Émile Maupas
François Émile Maupas (2 July 1842 in Vaudry – 18 October 1916 in Algiers) was a French librarian, protozoologist, cytologist, and botanist. Maupas contributed to ideas on the life cycle and reproduction of the ciliates. He founded the idea, known as the Maupasian life cycle, that some protists had a definite death following sexual reproduction, contrary to contemporary ideas on protists being immortal. He also identified the existence of mating types in ciliates. He developed culture techniques for a number of organisms and described the nematode ''Caenorhabditis elegans,'' which has since become a widely used model organism in biological studies. Life and work Maupas was born in Vaudry, to deputy mayor Pierre Augustin and Marie Adèle Geffroy. After studies at the local schools he joined the École des chartes, and from 1867 he worked as an archivist in Cantal. It was here that he developed an interest in natural history and began to study protozoa working in summer at ...

Hermann Burmeister
Karl Hermann Konrad Burmeister (also known as Carlos Germán Conrado Burmeister) (15 January 1807 – 2 May 1892) was a German Argentine zoologist, entomologist, herpetologist, botany, botanist, and coleopterologist. He served as a professor at the University of Halle, headed the museum there and published the ''Handbuch der Entomologie'' (1832–1855) before moving to Argentina where he worked until his death. Career Burmeister was born in Stralsund, where his father was a customs officer. He studied medicine at University of Greifswald, Greifswald (1825–1827) and Halle (Saale), Halle (1827–1829), and in 1830 went to Humboldt University of Berlin, Berlin to qualify himself to be a teacher of natural history. His dissertation was titled ''De insectorum systemate naturali'' and graduated as a doctor of medicine on November 4, 1829 and then received a doctor of philosophy on December 19 in the same year. He then joined for military service in Berlin and Grünberg (Silesia). He ...

1842 Births
__NOTOC__ Year 184 ( CLXXXIV) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Eggius and Aelianus (or, less frequently, year 937 ''Ab urbe condita''). The denomination 184 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

19th-century French Zoologists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ...

History Of Research On Caenorhabditis Elegans
The nematode worm '' Caenorhabditis elegans'' was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics. In 1974, Brenner published the results of his first genetic screen, which isolated hundreds of mutants with morphological and functional phenotypes, such as being uncoordinated. In the 1980s, John Sulston and co-workers identified the lineage of all 959 cells in the adult hermaphrodite, the first genes were cloned, and the physical map began to be constructed. In 1998, the worm became the first multi-cellular organism to have its genome sequenced. Notable research using ''C. elegans'' includes the discoveries of caspases, RNA interference, and microRNAs. Six scientists have won the Nobel prize for their work on ''C. elegans''. Early research ''C. elegans'' was first described in 1900 by Émile Maupas ...
