Julius Arnold Koch
Julius Arnold Koch (August 15, 1864 – February 2, 1956) was an American chemist who was born in the Free Hanseatic City of Bremen. Koch graduated from the University of Pittsburgh in 1884. He was the first Dean (education), dean of the University of Pittsburgh School of Pharmacy, School of Pharmacy at the University of Pittsburgh and held this position until his retirement in 1932. In 1897, he discovered, together with Ludwig Gattermann, the Gattermann-Koch reaction (a method of synthesis of benzaldehyde using CO). He agreed on receiving the status of dean only after his following concern was taken into consideration "I will accept the deanship if the sessions are changed from evening to the daytime."

Free Hanseatic City Of Bremen
Bremen (), officially the Free Hanseatic City of Bremen (german: Freie Hansestadt Bremen; nds, Free Hansestadt Bremen), is the smallest and least populous of Germany's 16 states. It is informally called ("State of Bremen"), although the term is sometimes used in official contexts. The state consists of the city of Bremen and its seaport exclave, Bremerhaven, surrounded by the larger state of Lower Saxony in northern Germany. Geography The state of Bremen consists of two non-contiguous territories. These enclaves contain Bremen, officially the 'City' (''Stadtgemeinde Bremen'') which is the state capital, and the city of Bremerhaven (''Stadt Bremerhaven''). Both are located on the River Weser; Bremerhaven ("Bremen's harbour") is further downstream on the mouth of the Weser with open access to the North Sea. Both enclaves are completely surrounded by the neighbouring State of Lower Saxony (''Niedersachsen''). The highest point in the state is in Friedehorst Park (32.5m). Hi ...

Benzaldehyde
Benzaldehyde (C6H5CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is the simplest aromatic aldehyde and one of the most industrially useful. It is a colorless liquid with a characteristic almond-like odor. The primary component of bitter almond oil, benzaldehyde can be extracted from a number of other natural sources. Synthetic benzaldehyde is the flavoring agent in imitation almond extract, which is used to flavor cakes and other baked goods. History Benzaldehyde was first extracted in 1803 by the French pharmacist Martrès. His experiments focused on elucidating the nature of amygdalin, the poisonous material found in bitter almonds, the fruit of ''Prunus dulcis''. Further work on the oil by Pierre Robiquet and Antoine Boutron-Charlard, two French chemists, produced benzaldehyde. In 1832, Friedrich Wöhler and Justus von Liebig first synthesized benzaldehyde. Production As of 1999, 7000 tonnes of synthetic and 100 tonnes of natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Bremen (city)
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

19th-century American Chemists
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemische Berichte
''Chemische Berichte'' (usually abbreviated as ''Ber.'' or ''Chem. Ber.'') was a German-language scientific journal of all disciplines of chemistry founded in 1868. It was one of the oldest scientific journals in chemistry, until it merged with ''Recueil des Travaux Chimiques des Pays-Bas'' to form ''Chemische Berichte/Recueil'' in 1997. ''Chemische Berichte/Recueil'' was then merged with other European journals in 1998 to form ''European Journal of Inorganic Chemistry''. History Founded in 1868 as ''Berichte der Deutschen Chemischen Gesellschaft'' (, CODEN BDCGAS), it operated under this title until 1928 (Vol. 61). The journal was then split into: * ''Berichte der Deutschen Chemischen Gesellschaft, A: Vereins-Nachrichten'' (, CODEN BDCAAS), and * ''Berichte der Deutschen Chemischen Gesellschaft, B: Abhandlungen'' (, CODEN BDCBAD). Vol. 78 and 79 (1945–1946) were omitted and not published due to World War II. The journal was renamed ''Chemische Berichte'' (, CODEN CHBEAM) in 19 ...

Ludwig Gattermann
Ludwig Gattermann (20 April 1860 – 20 June 1920) was a German chemist who contributed significantly to both organic and inorganic chemistry. Early life Ludwig Gatterman was born on 20 April 1860 in Goslar, an old mining town north of the Harz mountains. Two of his three siblings died at a young age. During his time in the Realschule he started experimenting. In 1880, he wanted to study at the University of Leipzig, but he had to complete his compulsory military service before he could start. He started his studies in 1881. After one year with Robert Bunsen at the University of Leipzig, he visited Liebermann for one semester at the University of Berlin to improve his skills in organic chemistry. Gattermann chose the University of Göttingen, which was close to Goslar for his further studies. He started his thesis under the supervision of Hans Hübner, who died in 1884, and finished his Ph.D. in 1885. As successor of Hans Hübner, Victor Meyer came to Göttingen and som ...

Dean (education)
Dean is a title employed in academic administrations such as colleges or universities for a person with significant authority over a specific academic unit, over a specific area of concern, or both. In the United States and Canada, deans are usually the head of each constituent college and school that make up a university. Deans are common in private preparatory schools, and occasionally found in middle schools and high schools as well. Origin A "dean" (Latin: ''decanus'') was originally the head of a group of ten soldiers or monks. Eventually an ecclesiastical dean became the head of a group of canons or other religious groups. When the universities grew out of the cathedral schools and monastic schools, the title of dean was used for officials with various administrative duties. Use Bulgaria and Romania In Bulgarian and Romanian universities, a dean is the head of a faculty, which may include several academic departments. Every faculty unit of university or academy. The ...
