Fischer indole synthesis: A class of chemical reaction in which a phenylhydrazine is reacted with an aldehyde or ketone to form an indole
Fischer-Tropsch process: The synthesis of hydrocarbons by the catalytic hydrogenation of carbon monoxide
Fischer projection: Method of representing the three-dimensional structures of molecules on a page, devised by Emil Fischer. By convention, horizontal lines represent bonds projecting from the plane of the paper toward the viewer, and vertical lines represent bonds projecting away from the viewer. Fischer projections are a convenient way to depict chiral molecules (see optical activity) and distinguish between pairs of enantiomers (see racemate). They are most often used to depict isomers of the sugars. See also chemical formula
fischer's slime mushroom: a type of slime mushroom
Bobby Fischer: orig. Robert James Fischer born March 9, 1943, Chicago, Ill., U.S. U.S. chess master. He became a grandmaster at age 15, then a record. In 1972 Fischer defeated Boris Spassky to become the only American to win the world chess championship. An intense and eccentric personality, he was a devout Christian fundamentalist who frequently condemned the Soviet Union for godlessness; he was deprived of his title in 1975 after refusing to meet his Soviet challenger, Anatoly Karpov. He remained out of the game thereafter except for a victorious private rematch with Spassky in Yugoslavia in 1992; the game violated U.S. sanctions against Yugoslavia, and Fischer has remained abroad ever since
Dietrich Fischer-Dieskau: born May 28, 1925, Berlin, Ger. German baritone and conductor. He had his first extensive performance experience as a prisoner of war in Italy, and he made his professional debut in 1947. One of the most remarkable singers of his time, he was equally successful in the often mutually exclusive realms of opera and lied. His lyrical voice was supported by his commanding presence, intelligent musicianship, and superb artistry. He recorded most of the standard art-song repertoire, as well as numerous unusual and contemporary works; his many premieres included Benjamin Britten's War Requiem (1962)
Emil Fischer: born Oct. 9, 1852, Euskirchen, Prussia died July 15, 1919, Berlin, Ger. German organic chemist. He received his Ph.D. in 1874. He determined the structures of uric acid, caffeine, and related compounds, showing that all are derivatives of a single compound he named purine. This led him to study protein structure and the ways in which amino acids are combined in proteins. He determined the molecular structures of glucose, fructose, and many other sugars, verifying his results by synthesizing each, and distinguished the 15 stereoisomers of glucose (see isomer; configuration; optical activity). His researches into the sugars were of unparalleled importance to organic chemistry and earned him in 1902 the second Nobel Prize for Chemistry. His investigations of fermentation laid the foundations of enzyme chemistry
