Science and technology in Venezuela

Science and technology in Venezuela includes research based on exploring Venezuela's diverse ecology and the lives of its indigenous peoples.

Under the Spanish rule, the monarchy made very little effort to promote education in the American colonies and in particular in those in which they had less commercial interest, as in Venezuela. The country only had its first university some two hundred years later than Mexico, Colombia or Peru.

The first studies on the native languages of Venezuela and the indigenous customs were made in the middle of the XVIII century by the Catholic missionaries. The Jesuits Joseph Gumilla and Filippo Salvatore Gilii were the first to theorize about linguistic relations and propose possible language families for the Orinoco river basin. The Swedish botanist Pehr Löfling, one of the 12 Apostles of Carl Linnaeus, classificated for the first time the exuberant tropical flora of the Orinoco river basin.

In the nineteenth century, several scientists visited Venezuela such as Alexander Humboldt, Aimé Bonpland, Francisco Javier de Balmis, Agostino Codazzi, Jean-Baptiste Boussingault, Mariano Rivero, François de Pons, Auguste Sallé, Robert Hermann Schomburgk, Wilhelm Sievers, Carl Ferdinand Appun, Gustav Karsten, Adolf Ernst, Benedikt Roezl, Karl Moritz, Friedrich Gerstäcker, Anton Goering, Johann Gottlieb Benjamin Siegert, Augustus Fendler, Federico Johow, Charles Waterton, Alfred Russel Wallace, Everard im Thurn, François Désiré Roulin, Jean Chaffanjon, Frank M. Chapman, Émile-Arthur Thouar, Jules Crevaux and many others, some of whom are buried in Venezuela.

The Venezuelan Institute for Scientific Research (IVIC) founded on February 9, 1959, by government decree, has its origins in the Venezuelan Institute of Neurology and Brain Research (IVNIC) which Dr. Humberto Fernandez Moran founded in 1955.

Other major research institutions include the Central University of Venezuela and the University of the Andes, Venezuela.

Notable Venezuelan scientists include nineteenth century physician José María Vargas, the chemist Vicente Marcano and the botanist and geographer Alfredo Jahn (1867–1940). More recently, Baruj Benacerraf shared the 1980 Nobel Prize in Physiology or Medicine, (1955), Aristides Bastidas (1980), Marcel Roche (1987) and Marisela Salvatierra (2002) have been recipients of UNESCO's Kalinga Prize for promotion of the public understanding of science. On July 2, 2012, L. Rafael Reif – a Venezuelan American electrical engineer, inventor and academic administrator – was elected president of the Massachusetts Institute of Technology.

Pehr Löfling (Tolvfors Bruk, Gävle, Sweden, January 31, 1729 – San Antonio del Caroni (Guayana, Venezuela), February 22, 1756). Swedish botanist who studied at the University of Uppsala where he attended courses taught by Carl Linnaeus. When the Spanish ambassador at Stockholm asked Linnaeus to select a botanist for service in the American colonies, the professor at once named Loefling. He went to Spain in 1751 to learn Spanish, and then embarked with other scientists for Venezuela in February 1754. In Cumana he had entire charge of the department of natural history, and was assisted by two young Spanish doctors. He introduced the first microscope in Venezuela. His prematural death was considered a great loss to natural history, and especially to botany. Linnæus believed the loss irreparable. The manuscripts of Löfling, which were found after his death, were preserved by his two assistants and Linnnæus posthumously published his ''Iter Hispanicum, eller resa til Spanska Länderna uti Europa och America 1751 til 1756'' in 1758. Parque Löefling in Ciudad Guayana, Venezuela is named after him.

Henri François Pittier (August 13, 1857, Bex, Switzerland – January 27, 1950, Caracas, Venezuela) was a Swiss-born geographer and botanist. He graduated as an engineer from the University of Jena and moved to Costa Rica in 1887, where he founded the Physical Geographic Institute and an herbarium. Pittier arrived in Venezuela in 1917, where he classified more than 30,000 plants and devoted many years to studying the flora and fauna in the country. In 1937 had achieved the creation of the Rancho Grande National Park at north of Maracay, Aragua state, the first national park of Venezuela. The plant genera ''Pittiera'' (now considered a synonym of ''Polyclathra''), ''Pittierella'' (now considered a synonym of ''Cryptocentrum'') and ''Pittierothamnus'' (now considered a synonym of '' Amphidasya'') are named after him. His name is also associated with Pittier's crab-eating rat, ''Ichthyomys pittieri''. In 1953 the Rancho Grande National Park was renamed in his honour as Henri Pittier National Park.

William H. Phelps (New York, June 14, 1875 – Caracas, December 8, 1965) was an American ornithologist and businessman. He studied biology at Milton Academy and Harvard College. In the summer of 1896 he decided to go on an ornithological exploration to Venezuela following the advice of Wirt Robinson, who had visited Margarita Island the year before, and from his mentor Frank M. Chapman. After a long stay in Sucre and Monagas, he became fascinated with the country and its birds. He returned to the United States with a small collection of specimens that he brought to Chapman at the American Museum of Natural History. The specimens he collected became the basis for his first publication published with Chapman in 1897. Once he finished his studies at Harvard, Phelps returned to Venezuela in 1897, to marry Alicia Elvira Tucker and settle in Maturín. There he began one of many successful business ventures by selling coffee and in 1930 founded Radio Caracas Radio. In 1938 he founded the Phelps Collection considered the largest ornithological collection in Latin America and the largest private collection in the world. It is a mandatory study resource on tropical birds for experts who wish to know more about this area. Currently the Phelps Collection has a heritage of 80,000 birds in feathers, a thousand preserved in alcohol and 1,500 skeletons. His second son, William H. Phelps Jr. founded RCTV in 1953, became one of his foremost collaborators in all matters concerning ornithology.

Hermano Ginés (Bilbao, 1912 – Caracas, 2011). Born under the name of Pablo Mandazen Soto, Hermano Ginés arrived in Caracas in 1939, when Venezuela awoke from the lethargy of the long gomecista dictatorship. Poverty and illiteracy were combined with epidemics, when oil seemed to give a new impetus to the country.
It is thus that Hermano Ginés, creator of the La Salle Foundation of Natural Sciences, together with committed young students of the College La Salle, created in 1940 the Society of Natural Sciences La Salle, from which the Foundation La Salle was born in 1957. These visionaries sowed the seed of science, knowledge and education, in a country urged by lights. Several centers today rooted in most places of Venezuela, serving its people and its Environment.

Leandro Aristeguieta (Guasipati, 1923 – Caracas, 2012), botanist graduated at the Central University of Venezuela. In 1959 participated in the design of the Park of the East (now Park Generalísimo Francisco de Miranda) together with Brazilian landscape architect Roberto Burle Marx, Fernando Tabora and John Stoddart, who combined the majesty of the national flora with a small but varied zoological collection. Individual number of the Academy of Physical, Mathematical and Natural Sciences, having been 1st vice-president (1997–2001), and president (2001–2003). In his honor was designated a Hall of the Faculty of Sciences of the Central University of Venezuela. Doctor Honoris Causa of the University of Carabobo.

Francisco Mago Leccia (Tumeremo, Bolívar State, Venezuela, May 21, 1931 – Puerto La Cruz, Anzoátegui State, Venezuela on February 27, 2004). Mago was a distinguished Venezuelan ichthyologist who specialized in electric fish of the rivers and lagoons of South America, particularly of Venezuela. His education was Docent in Biology and Chemistry graduate from the "Instituto Pedagógico de Caracas", (today Universidad Pedagógica Experimental El Libertador), Master of Sciences (Marine Biology) from the University of Miami, Florida, U.S.A., Doctor in Sciences from Universidad Central de Venezuela.

Niklaus Grünwald (born in Caracas in 1965). Venezuelan- American biologist and plant pathologist of German and Swiss ancestry. He obtained a Bachelor of Science in plant science at University of California, Davis (UC Davis) in 1992. He completed his PhD in ecology and plant pathology in 1997 at UC Davis studying the effect of cover crop decomposition on soil nutrient cycling and soil microbiology. Grünwald pursued postdoctoral research at Cornell University. His academic research focuses on the evolution, genomics, and ecology of plant pathogens in the genus Phytophthora and management of the diseases they cause. This pathogen group includes some of the most costly diseases affecting crops and ecosystems. These pathogens have well characterized effectors to circumvent plant host recognition that in the genus Phytophthora include RxLR, Crinkler and other small secreted proteins. Grünwald is best known for providing novel insights into how plant pathogens emerge, methods to study pathogen evolution, particularly when populations are clonal, and characterizing the evolutionary history of Phytophthora pathogens. He is currently working with the USDA Agricultural Research Service, a professor (courtesy) in the Department of Botany and Plant Pathology at Oregon State University, and a professor (adjunct) in the Department of Plant Pathology and Plant-Microbe Biology at Cornell University.

Epidemiology

Louis-Daniel Beauperthuy (Basse-Terre, Guadeloupe, France, August 25, 1808 – Demerara, British Guiana, September 3, 1871) was a Venezuelan-French physician who made important contributions to the study of the causes of infectious diseases such as yellow fever, malaria, and leprosy. He was the first to systematically argue that malaria and yellow fever were transmitted by mosquitos. He studied medicine at the Paris Faculty of Medicine, and obtained his M.D. in 1837. He was immediately appointed by the Paris Museum of Natural History as a "Travelling Naturalist" to work in Orinoco basin, Venezuela. He was one of the earliest scientists to observe microorganism using microscopy in relation to diseases. In 1838 he developed a theory that all infectious diseases were due to parasitic infection with "animalcules" (microorganisms). With the help of his friend M. Adele de Rosseville, he presented his theory in a formal presentation before the French Academy of Sciences in Paris. He suspected that mosquitos were the carriers of the infectious pathogens, including those of leprosy. In 1842 he worked at the Facultad Médica de Caracas (Caracas Medical School). In 1850 he became professor of anatomy at the School of Medicine of the college of Cumana. He was appointed the director of the Leper Hospital in Demerara in British Guiana, the post he held till his death. By 1853, he was convinced that malaria and yellow fever were spread by mosquitos. He even identified the particular group of mosquitos that transmit yellow fever as the "domestic species" of "striped-legged mosquito", which can be recognised as ''Aedes aegypti'', the actual vector. He published his theory in 1854 in the ''Gaceta Oficial de Cumana'' ("''Official Gazette of Cumana''"). His reports were assessed by an official commission, which discarded his mosquito theory. Only after 1891, with the works of Carlos Finlay, his investigations are reviewed with seriousness. A hospital in Basse-Terre, called the Centre hospitalier Louis-Daniel Beauperthuy, was established in 1959 in his honour.

Rafael Rangel (Betijoque, 1877-Caracas, 1909). Venezuelan scientist and researcher, who devoted himself to tropical diseases. He is considered the father of parasitology and bioanalysis in Venezuela. He is famous for being the first to describe in Venezuela the ''Necator americanus'', parasite that caused hookworm, between 1903 and 1904. As a researcher, in 1902 Rangel was appointed first director of the laboratory of histology and bacteriology of Vargas Hospital. In 1908, at the request of President Cipriano Castro, he was in charge of the sanitary campaign to eradicate bubonic plague in La Guaira. A year later, after falling into depression by several problems that arose during the plague and by the refusal to a longed for scholarship abroad, he committed suicide with cyanide. His remains were buried in the National Pantheon on August 20, 1977.

Arnoldo Gabaldón ( Trujillo, March 1, 1909 – Caracas, September 1, 1990) was a physician, researcher and politician. Graduated in 1928 earned a doctorate in medical sciences at the Universidad Central de Venezuela. In (Germany) completed a specialty at the Institute for Maritime and Tropical Diseases of Hamburg. Later traveling in 1935 to the United States as a fellow of the Rockefeller Foundation to obtain a doctorate from Johns Hopkins University in hygiene sciences with speciality in protozoology. Back in Venezuela he was appointed to head the newly created Special Directorate of Malariology within the Ministry of Health and Welfare, a position he held until 1950. Under the direction of Gabaldón, Venezuela became the first country which organized a nationwide campaign against malaria by using DDT, which led to be the first to achieve eradication of the disease in a large area extension of the tropical zone.COLMENARES ARREAZA, Guillermo
Arnoldo Gabaldón (1909–1990)
''Gac Méd Caracas'', mar. 2006, vol.114, no.1, p.69-69. ISSN 0367-4762. He also discovered new species of malarial parasites and devoted himself to studying the mosquito ''Anopheles nuneztovari'', action that catalyzed the recognition of educational needs and preparing managerial staff of the Ministry of Health, through the creation of the school that bears his name in Maracay, a deep and additional contribution.http://www.iaesp.edu.ve/index.php/iae Between 1959 and 1964 President Rómulo Betancourt appointed him Minister of Health and Welfare and Gabaldón. He was the first professor of the Simón Bolívar Chair of Latin-American Studies at the University of Cambridge, England (1968–69) and directed post-doctoral studies at the Central University of Venezuela. Gabaldón wrote more than 200 papers published in national and international medical journals. Gabaldón was active as an expert of the World Health Organization (WHO) for malaria control in countries from 5 continents.

Jacinto Convit (Caracas, September 11, 1913 – Caracas-May 12, 2014) was a physician and researcher, known for developing a vaccine to fight leprosy and his studies to cure different types of cancer. In 1987, he received the Prince of Asturias Award in the Scientific and Technical Research category. Inspired by leprosy victims, he entered medical school at Central University of Venezuela (UCV) in 1932. He earned his title as a Medical Science Doctor in 1938. In 1968, Convit was elected president of the International Leprosy Association (ILA) and was re-elected in 1973. In 1971, Convit was named by the WHO as director of the Co-operative Centre for the Study and Histological Classification of Leprosy. In 1976, Convit was elected director of the Pan American Research and Training in Leprosy and Tropical Diseases. He was also named president of the ''International Journal of Leprosy''. In 1987, Convit added killed ''Mycobacterium leprae'' to the BCG vaccine. The combined vaccine was tested worldwide, but was not more effective than regular BCG. A vaccine for leishmaniasis was later developed using Convit's method. He also worked on mycosis, onchocerciasis, and other tropical diseases. In 1988, the Venezuelan government nominated Convit for a Nobel Prize in Medicine for his experimental anti-leprosy vaccine.

Felix Pifano (San Felipe, Yaracuy, May 1, 1912 – August 8, 2003) was a Venezuelan physician and researcher, graduated in the Central University of Venezuela (1935) and laureate of the National Academy of Medicine in Paris. Back in Yaracuy he practiced tropical medicine with Enrique Tejera in the institute that he had founded 10 years earlier, treating diseases such as leishmaniasis, tuberculosis, diarrhea, and malaria. Together with Arnoldo Gabaldón he traveled through Central America in 1938 to follow the work of the Rockefeller Foundation in Costa Rica and Panama. With this training he worked with Gabaldón in the newly created Venezuelan Institute of Malariology, leading the effort to eradicate the yellow fever of Venezuela. In that position, along with Martín Mayer founded the research section of the National Institute of Hygiene in Caracas. In his recently founded section he studied Chagas disease, ''Trypanosoma rangeli'', cutaneous and visceral leishmaniasis, intestinal and hepatic amebiasis, schistosomiasis, onchocerciasis, Systematic mycoses, malnutrition and poisonous animals. During the dictatorship of Marcos Perez Jiménez signed a document prepared by Arturo Uslar Pietri that forces him to exile in Mexico, where he studied cardiology. With the fall of the Venezuelan dictator, Pifano returned to Venezuela and founded the Institute of Tropical Medicine of the UCV and directed it for almost 50 years. This institute earned him immense affection from his disciples and respect in all spheres of national society.

Microbiology

Manuel Núñez Tovar ( Caicara, Monagas, September 24, 1872 – Maracay, Aragua, January 27, 1928) was naturalist, researcher, parasitologist and entomologist. Nuñez Tovar began his studies at Caicara and later continued in Maturin, where he graduated from high school at age 16. The first two years studied medicine at the Federal College of Barcelona and gained the title at the Central University of Venezuela in 1895. In 1909, with Cesar Flamerich and Rafael Nuñez Isava, he was part of the Public Health Commission, and that same year he began his studies in entomology. In this discipline studied the importance of insects as vectors in the transmission of diseases, was the author of numerous papers and identified ''Necator americanus'' as the cause of anemia in patients who had suffered from malaria. After twenty years in Monagas state, Nuñez Tovar lived temporarily in Caracas and La Victoria, settling permanently in Maracay after being appointed medical brigade in the garrison of the city. During this time many animal species collected in the valleys of Aragua and around the Lake Valencia (Venezuela). Nuñez never left Venezuela, but scientists visited the country to personally know the voluminous scientific work included the discovery of several species of mosquitoes that carry his name. For his scientific legate, a high school and University Hospital of Maturin were named in his honor and his entomology collection was acquired by the government of Venezuela. This is preserved in the Department of Malariology and Environmental Sanitation, Ministry of Health of Maracay.

Engineering

Civil engineering

Alfredo Jahn (Caracas, 1867– Caracas,1942) finished his studies at the Central University of Venezuela in 1886. The following year, he participated in the preliminary studies for the construction of a major railroad between Caracas and Valencia with extension to San Carlos. As a Civil Engineer, he worked with civil engineer and lawyer German Jimenez in the National Plan of Highways and Railroads of Venezuela by order of the National Government. He was responsible for the construction of the railroad from Caracas to Valencia. He also built the highway from Caracas to El Junquito. In 1887 he accompanied the Venezuelan chemist Vicente Marcano on a scientific expedition to the upper Orinoco river, sent by President Antonio Guzmán Blanco. The trip provided geographical positions and a collection of plants and archaeological objects found today in United States and Germany. As a geographer he identified the levels of the Lake of Valencia, its tributaries river and determined all the heights of the Range of the Coast. He lived with the Orinoco basin indigenous people and wrote books on their customs and dialects. As a botanist he classified many plants in Venezuela, donated rare specimen samples to the Smithsonian Institution, and wrote a book on the Palms of Venezuela (''the Palms of the Flora Venezuelana'' – Caracas 1908). In 1911 he became the first person to ascend Pico Humboldt in the Sierra Nevada de Mérida in Venezuela.

Food engineering

Carlos Roubicek (Praga, 1916– Caracas, 2004) Czech master brewer of Jewish origin. In 1937 emigrated to Ecuador after the occupation of his country by Adolf Hitler troops. On January 1, 1943, he joined the Polar Group of Venezuela founded in 1941 by Lorenzo Alejandro Mendoza Fleury. Four months after his entry, Roubicek raised the board of directors the need to change the formula of the beer as it detected that the consumer wanted a product more refreshing and so adapt it to the Venezuelan palate and our tropical climate. Then decided to make a variation in the ingredients of the beer, replace 20% of the malted barley with corn flakes (also known as beer chips) and add more carbon dioxide. So he managed to reformulate the Polar beer adapting it to the consumer's taste, printing it an unrivaled body and flavor. This led her quickly to occupy the first place in the preference of Venezuelans. In 1954 created the process to produce the corn flake for Polar Group in order to substitute the import of this raw material. Counting by then with three brewing plants in operation and being the corn flakes one of the main ingredients of the beer formula, the company decided to build its own corn processing plant in Turmero, Aragua state. This decision would be a decisive step in the later development of the food business the precooked maize flour Harina P.A.N. for the arepas. Roubicek told: "Juan had the idea of making a flour to make arepas with the corn flakes that we used in the beer industry. I met with some manufacturers of arepas – in areperas – that existed in the country and they considered our project to be very complicated. I thought that if we changed the grinding and the humidity of the "Corn Flakes", we could get a precooked flour that would not give so much work to the housewife. I called a Remavenca technician to prepare a sample and we got what we wanted."
Launched in 1960 the Harina P.A.N. rapidly gained acceptance among housewives because of the tremendous saving in domestic labor and its high quality.

Structural engineering

Ibrahim López García ( Cabure, 1925 – Maracaibo, 1994). A visionary like few formed in civil engineering, exerted for many years the teaching and the investigation in the Central University of Venezuela and the University of Zulia. His practice was based on a careful observation of nature, its surprising structures and designs. He tried to make engineering proposals lighter and fresh, optimizing resources and reducing environmental impact. As a result of these deep convictions, he founded the Social Ecological Movement for the XXI Century at the end of the sixties, with strong environmental principles. He also carried out several construction projects such as the roof of the "José Pérez Colmenares Stadium" ( Maracay, Aragua state) in which his new thinking becomes evident with a design inspired by the shape of the palm leaf. In 1970, he prepared a challenging work of promotion, titled ''On tops, domes and flights'' that tried to break with some paradigms of the modernity. First, it criticizes our reliance on fire-based technology, on combustion, by proposing the use of alternative energies. He criticizes that humans have been inspired by fish and birds to design aircraft, helicopters and submarines since its principle is linear, which in its opinion has the result of waste of energy and fuel. Thanks to a study that for a long time made on the spores, shells of turtles and other natural domes, proposes the construction of an airship based on the way of moving of these beings. His airship model consisted of a large central dome surrounded by a ring of aerodynamic rotating domes that would allow it to travel in the air and even in the water, to which is added an engine that applies the laws of electromagnetism.

Petroleum engineering

Gustavo Inciarte Perich (1938, Maracaibo, Venezuela – 2010, Norman, Oklahoma).

Inciarte was the first Venezuelan to become chief petroleum engineer for any of SHELL's Group of Companies Worldwide, and after many years of a very successful career in PDVSA was named the first president of INTEVEP (Venezuela's Technology Research and Development Center). In 1998 he was the first Latin American elected as president of the Society of Petroleum Engineers (SPE). In 1998 ended his 41-year career in the oil industry as a member of PDVSA board which was, at the time, one of the biggest oil companies in the world. Since 2003 he was a visiting research scholar at the University of Oklahoma, in the Sarkeys Energy Center, and worked mainly with the Energy Institute of the Americas.

Inventors

Carlos del Pozo y Sucre (1743, Calabozo – 1814, Camaguán) is probably the first outstanding inventor that Venezuela had. Alexander von Humboldt mentions a meeting with this man in 1800 cite:''We found in Calabozo, in the heart of the plains, an electric machine of large disks, electrophores, batteries, electrometers, a material almost as complete as that of our physicists in Europe. All these objects had not been purchased in the United States; Were the work of a man who had never seen any instrument, which no one could consult, who did not know the phenomena of electricity more than by reading the Treaty of Sigaud de Lafond (Joseph Aignan Sigaud de Lafond) and the Memoirs of Franklin (Benjamin Franklin).'' Journey to the Equinoctial Regions of the New Continent.
In 1804 participated with the Spanish scientist Francisco Javier Balmis in the vaccination against smallpox in Venezuela. Del Pozo was a partisan of the Spanish colonial government and for this reason he received no support from the new independist government established in 1811. He died forgotten in 1814.

Johann Gottlieb Benjamin Siegert (Grosswaltz, 1796– Ciudad Bolivar, 1870), German surgeon general in Simón Bolívar's army who developed the recipe of the called Angostura bitter as a tonic for soldiers affected by upset stomachs and tropical diseases. Siegert began to sell it in 1824 and established a distillery for the purpose in 1830. Siegert was based in the town of Angostura, now Ciudad Bolívar, and used locally available ingredients, perhaps aided by botanical knowledge of the local Amerindians.Raymond,

January 10, 2000 The product was exported abroad from 1853 used for flavouring cocktails, beverages or less often, food. In 1875 the plant was moved from Ciudad Bolivar to Port of Spain, Trinidad, where it remains. Angostura bitter won a medal at the Weltausstellung 1873 Wien. The medal is still depicted on the oversized label, along with reverse which shows Emperor Franz Joseph I of Austria in profile. The exact formula is a closely guarded secret, with only one person knowing the whole recipe, passed hereditarily.

Luis Zambrano (Bailadores, 1901 – Tovar, 1990) was a Venezuelan self-taught inventor and popular technologist. He left formal education after the fourth year of primary school, but soon began to develop an interest in mechanics, enjoying discovering for himself the speed ratios produced by connecting oranges of different diameters and rotating them by means of jets of water. These gadgets lead him to consider new challenges and discover of physical principles in practical ways. In his Valle Nuevo workshop, near Bailadores, he empirically and intuitively learned enough about water turbines to generate electricity and mechanics to allow him to create about 50 inventions, some of which were commissions, such as a strawberry-peeling machine and a sieve for categorising garlic, and numerous improvements to various different machines, despite having lost his right hand to a saw in an accident in 1977. In November 1984, the University of Los Andes awarded him the title of Doctor Honoris Causa "for his useful creative work", the first time that this award had been given to a country man. He was declared an illustrious son of Bailadores, and a street in this Méridan village is now named after him.

Luis Caballero Mejias (Caracas, 1903– Caracas, 1959) was a Venezuelan engineer who invented the Precooked maize flour for the arepas in the 1950s. The traditional preparation of arepa flour is very labor-intensive, requiring the pounding of maize in a large mortar, boiling and grinding. Caballero used the profits from his patent to finance a Technical Schools system. The precooked flour was later mass-produced and sold in larger quantities. In 1954, the Venezuelan beer and malted drinks company Empresas Polar developed an industrial production method, launching the brand Harina P.A.N. in 1960. The product rapidly gained acceptance among housewives because of the tremendous saving in domestic labor and its high quality. The original slogan was'' "Se acabó la piladera"'', which means ''"No more pounding"''. Harina P.A.N. has remained essentially unchanged since then, as can be seen from the original advertisements.

Humberto Fernández-Morán (Maracaibo, February 18, 1924 – Stockholm, March 17, 1999) was a Venezuelan research scientist, renowned for inventing the diamond knife or scalpel, significantly advancing the development of electromagnetic lenses for electron microscopy based on superconducting technology, and many other scientific contributions. Dr. Fernández-Morán founded the Venezuelan Institute for Neurological and Brain Studies, the predecessor of the current Venezuelan Institute of Scientific Research (IVIC). In 1958 he was appointed Minister of Education during the last year of the regime of Marcos Pérez Jiménez and was forced to leave Venezuela when the dictatorship was overthrown. He worked with NASA for the Apollo Project and taught in many universities, such as Massachusetts Institute of Technology, University of Chicago and the University of Stockholm. In the United States he was proposed to be nominated for the Nobel Prize. He rejected the nomination because he would have had to embrace American citizenship, which he refused, wanting to maintain his Venezuelan nationality. Among honors and awards includes the John Scott Medal, Dr. Eugene Garfield is member of the Advisory Committee.
Knight of the Order of the Polar Star, Claude Bernard Medal, Cambridge annual Medical Prize.

Medicine

Experimental medicine

Blessed José Gregorio Hernández ( Isnotu, 1858-Caracas, 1919). Graduated as a medical doctor at ''Universidad Central de Venezuela'', in Caracas. The Venezuelan government awarded him a grant to continue his studies in Europe. Hernández traveled to Paris, France, where he studied other fields of medicine such as: bacteriology, pathology, microbiology, histology, and physiology. Following his return to Venezuela, he became a leading doctor at the ''Hospital José María Vargas''. Between 1891 and 1916, Hernández dedicated himself to teaching, medicine, and religious practice. He sought priesthood in two occasions, but his fragile physical conditions would ultimately prevent him from achieving that status. He studied at the ''Monastery of Lucca'' in Italy for ten months in 1908. In 1913, he enrolled at the ''Latin American Pío School of Rome'' to continue the priestly career, but had to return to Venezuela for health reasons. Among the scientific publications of this famous Venezuelan are ''The Elements of Bacteriology'' (1906), ''About the Angina Pectoris of Malaric Origin'' (1909) and ''The Elements of Philosophy'' (1912). Dr. Hernández treated the poor for free and even bought them medicines with his own money. One day in 1919, while bringing medicine to the home of one of his patients in Caracas, Hernández was struck by a car and killed. In 1986 the Pope John Paul II solemnly declared his heroic virtues, for which he was granted the title of Venerable. After more than 80 years of investigating the first miracle that Hernández did, on 30 April 2021, was beatified in Caracas, Venezuela. He is currently in the process of canonization.

(Barcelona 1879 – Ciudad de Mexico, 1965). Graduate in medicine at the University of Barcelona in 1899 gained a doctorate at the University of Madrid in 1900 with a thesis on anaerobic life. He worked as an assistant professor of physiology in Barcelona in 1902 under Ramon Coll i Pujol, and in 1904 obtained the chair in the University of Seville. In 1906 he presided over the executive committee of the First Congress of Hygiene of Catalonia and in 1907 resigned to the chair to return to Barcelona to dedicate itself to the investigation. In 1914 was named professor of physiology of the Faculty of Medicine of the University of Barcelona, of which in 1916 happened to be full professor.

From then until he went into exile he devoted himself to medicine. He created a physiological research center in the Barcelona Municipal Laboratory, led by Ramon Turro i Darder, who was his friend and considered himself a disciple. From his experiments with animals he made various discoveries about reflexes, physical stimuli, and their influence on respiration. In 1920 he went to direct the Institute of Physiology of the Commonwealth, where he created a school of certain international prestige. In 1912 he founded the Catalan Society of Biology, was president of the Barcelona Royal Academy of Medicine between 1926 and 1939 and was director of the publication Treballs de la Societat de Biologia (1913–1938), where he published most of his works.

After the outbreak of the Spanish Civil War, in 1939 he was exiled with his family to Paris and from there to Caracas, after receiving an invitation from the Venezuelan government to work as professor of physiology in the faculty of medicine of the Central University of Venezuela in 1940. He also directed the Institute of Experimental Medicine, where he formed a school of physiology like that of Barcelona. From 1946 he worked as a professor of biochemistry and, since 1942, as professor of biology and biochemistry at the National Pedagogical Institute of Caracas. In 1955 nationalizated as Venezuelan Pi Sunier wrote in Caracas ten books and two novels, apart from the essays and monographs collected in scientific journals and in cultural publications, which is an inventory of great value that earned him the Kalinga Prize, granted by UNESCO in 1955.

Surgery

José María Vargas (La Guaira, March 10, 1786 – New York City, April 13, 1854) graduated with a degree in philosophy from the Seminario Tridentino obtained in 1809 his medical title from the Real y Pontificia Universidad de Caracas. Vargas was imprisoned by the Spanish in 1813 for revolutionary activities. Upon his release in 1813, he travelled to Scotland for medical training in the University of Edinburgh. Vargas performed cataract surgery. He was one of the earliest eye surgeons in Puerto Rico after his arrival there in 1817. He returned to Venezuela to practice medicine and surgery in 1825. Elected as President of Venezuela in 1834 he resigned his charge in 1836. In 1839 Vargas receives from the President Paez office, an oil sample found in Pedernales, located in the Canton of the Lower Orinoco. He submits it to various physical-chemical analyzes involved the fractional distillation and wrote a much more complete report than the " Silliman Report" which was written 16 years later and which nevertheless appears in texts, as the first scientific report on oil. His final paragraph confirms the wisdom of Vargas: ''"this finding is more precious and worthy of congratulation than that of the mines of silver and gold." ''It amazes that such phrase was written decades before the invention of the engine to explosion that uses petroleum derivates to move all the cars and airplanes in the 20th century." Likewise, he continued to give his anatomy and surgery classes at the University, and in 1842 founded the Chair of Chemistry. In 1877, his ashes were brought to Caracas and buried in the National Pantheon on April 27 of that same year.

Luis Razetti ( Caracas, September 10, 1862 – May 14, 1932) was a surgeon who supported and managed a number of advances in the progress of Venezuelan medicine. He is considered the driving-force in the "Renaissance of the Venezuelan medicine", concerning education, research centers and medical practices in Venezuela. One of the two schools of Medicine of the Central University of Venezuela bears his name.

Razetti gained his doctorate in medicine from the Central University of Venezuela (August 4, 1884), to a month to turn 22 years old. So, a few days later traveled to the countryside, where he played his first professional years, particularly in the states Lara, Zulia and the Andes, back to Caracas after 5 years (1884 / 1889). In 1890 he moved to Paris, where he made his postgraduate studies (1890 / 1893), specializing in surgery and Obstetrics. The influence of the French school, dominant then, made a deep and lasting impression on his mind, although he continued to draw on other sources, which is evident in his admiration for Santiago Ramón y Cajal, Charles Darwin and Ernst Haeckel. Among his most notable contributions may mention, in chronological order as follows:

* The founding of the Society of Physicians and Surgeons of Caracas (1893).
* The establishment of clinical teaching in the Central University of Venezuela.
* The establishment of the contests of internship and externship hospitals (1895).
* The reform of the chairs of Anatomy and Operative Medicine (1895 / 1896).
* The founding of the College of Physicians of Venezuela (1902).
* The foundation of the National Academy of Medicine (1904), which was permanent secretary.
* The creation of the Venezuelan Congress of Medicine (1911).

Miguel Pérez Carreño (Valencia, 1904– Caracas, 1966) was a physician, researcher, scientist, university professor and writer. He graduated with a bachelor's degree from the Central University of Venezuela with his thesis called ''Calor animal'' (Animal heat). In 1920 he re-entered the university to study medicine and before graduating he worked as a clinical monitor. He earned a PhD in Medical Sciences in October 1926 with the presentation of the thesis ''Autoseroterapia de los derrames'' (Auto-serum therapy of effusions) and then devoted himself largely as a teacher. Between 1933 and 1934 he completed his academic training at hospitals of New York City, Paris and Vienna. He considered diagnosis an art that had to be accomplished not only through clinical history, but through long, sustained, conversation with the patient about their health problems and living conditions. Beginning in 1936, he worked on the study, analysis and evaluation of definitive treatment for surgical diseases. In Venezuela he did a series of interventions including pasacro nerve resection in the treatment of pelvic neuralgia, resection of the rectum with contra natura permanent anum, (1932), ovarian homografts (1936), the new technique of lymphatic blockade in infectious processes, carried out with electrosurgery linked with sulfonamide therapy (1938), the radical cure of rectal prolapse with fascia lata (aponeurosis of the thigh) ligation of the femoral artery by gangrene and embolectomy by phlebitis. He also contributed to improving the treatment of Banti syndrome (abnormal growth of the spleen) and portal hypertension (usually caused by liver cirrhosis). Active in the Caracas Polyclinic, the José María Vargas Hospital and the University Hospital, Perez-Carreño was head of descriptive practical anatomy procedures, head of surgical medicine, chief of clinical surgery and dean of the Faculty of Medicine, among other duties. He spent part of his last years on cancer research.
The hospital belonging to the National Institute of Social Security, located to the west of Caracas, bears his name.

Rene Sotelo (Caracas 1961) is one of the most experienced laparoscopic/robotic surgeons in the world. He received his medical degree from Central University of Venezuela and has been in practice for more than 20 years from prestigious hospitals of Venezuela and Mexico, he is a pioneer in robotic surgery for complex urinary fistulae in females and males, benign prostate enlargement and inguinal lymph node dissection for cancer. He has helped develop the novel concepts of single-port belly-button and natural orifice surgery. His experience with advanced robotic and laparoscopic surgery exceeds 2,300 personal cases, making him amongst the most experienced in the world. He has published more than 50 peer reviewed scientific papers, three textbooks and 28 chapters in major urology books. He also serves on the editorial board of three urologic journals. In recognition of his work, Dr. Sotelo has been invited as international guest-lecturer in more than 35 universities in 19 countries. His unique skills and large personal experience in minimally invasive laparoscopic and robotic surgery are well known. He is a passionate teacher, having taught his techniques and best practices in 19 countries as an invited guest. To date, he has trained over 64 post-graduate fellows from 14 countries in the art and science of minimally invasive urology. It is because of these seminal achievements that Dr. Sotelo was selected to join the University of Southern California Keck School of Medicine. His passion for surgical innovation, advancing the field and worldwide teaching coincides with, and further strengthens, the philosophy at the USC Institute of Urology.

He lived in England, where he studied in the University of London, obtaining a PhD in quantum mechanics in 1969. From 1971 till 1990 he worked in academic matters continually, especially in research at the Centre of Physics, the Venezuelan Institute for Scientific Research (Full Researcher 1978) and at the physics department, Simon Bolivar University (full professor 1980), both in Caracas. He is full professor ad honorem at the Institute for Advanced Studies (IDEA, Caracas) having been a co-founder of IDEA in 1980. Since 1994 he is an associate member of the Dublin Institute for Advanced Studies and International Centre for Theoretical Physics(ITCP) in Trieste. His field of research is astrobiology, in other words the science of the origin, evolution, distribution and destiny of life in the universe, especially life on Europa, the Jovian satellite.

Humberto Campins (born in Barquisimeto, 1946) is an international expert on asteroids and comets. He attended the University of Kansas, where he earned a bachelor's degree in astronomy. He went onto the University of Arizona, where he earned a PhD in planetary sciences. As a graduate student he was named a representative to the Committee for Peaceful Uses of Outer Space of the General Assembly of the United Nations. He conducts research at observatories around the world, including Arizona, Chile, France, Hawaii, Spain and the Vatican. In 2010 he discovered water ice and organic molecules on the asteroid 24 Themis and later on 65 Cybele adding weight to the growing theory that Earth's water may have come from asteroids. His expertise have landed him on NASA and European Space Agency teams preparing interplanetary vehicles that will launch in the coming few years, including the OSIRIS-REx project and the Marco Polo-R mission. Since 2002 worked at the University of Central Florida and University of Arizona. He has earned several prestigious awards including a Fulbright and the Don Quijote Award. The asteroid, 3327 Campins, was named after him.

Gustavo Bruzual (born in Caracas, August 2, 1949). Astronomer and PhD degree in 1981 from the University of California in Berkeley, US. His thesis versed on Spectral Evolution of Galaxies. Then after he joined the staff at Centro de Investigaciones de Astronomía (CIDA) in Mérida, Venezuela, where he served for more than 30 years, including 21 years as director of the center. His research is centered on evolutionary population synthesis and modeling the spectral evolution of galaxies. His work in collaboration with S. Charlot (IAP, France) has become a landmark in the field. Their three papers together have received over 6200 citations. The Bruzual and Charlot (2003) models have proven very useful in deriving the physical properties of galaxies of different types observed in large galaxy surveys like the SDSS, allowing to characterize galaxies at various redshifts as belonging to the red sequence or the blue cloud, and providing an estimate of the stellar mass and its growth rate, in these systems. Currently G. Bruzual is working on improving different aspects of stellar population synthesis, like the treatment of TP-AGB and WR stars in spectral evolution models. Actually is investigador Titular at the Centro de Radioastronomía y Astrofísica (CryA) in the Morelia Campus of the Universidad Nacional Autónoma de México (UNAM) and professor at the UNAM Graduate Program in Astrophysics.
