Emil Fischer

German chemist (1852–1919)

For other people named Emil Fischer, see Emil Fischer (disambiguation).

Hermann Emil Louis FischerFRS FRSE FCS (German pronunciation:[ˈeːmiːlˈfɪʃɐ]^ⓘ; 9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also hypothesized lock and key mechanism of enzyme action. He never used his first given name, and was known throughout his life simply as Emil Fischer.^[2]^[3]^[4]^[5]

Early years and career

Fischer was born in Euskirchen, near Cologne, the son of Laurenz Fischer, a businessman, and his wife Julie Poensgen. After graduating he wished to study natural sciences, but his father compelled him to work in the family business until determining that his son was unsuitable. Fischer then attended the University of Bonn in 1871, but switched to the University of Strasbourg in 1872.^[6] He

Hermann Emil Fischer was an eminent German organic chemist who made brilliant contributions to the chemistry of natural products. He was an exemplary chemist and an excellent model for all future generations of chemists. He is considered one of the great “discoverers” of biochemistry. His main studies addressed the molecular structures of various biochemical molecules, especially sugars. He was the first to clarify the structures of various sugars and enzymes as well as of several other natural products, including glucose, caffeine, and uric acid, and to demonstrate the mechanisms of their formation. He synthesized several amino acids and created small chains thereof as precursors to protein formation. He defined the “lock-and-key” mechanism to explain how enzymes can catalyze certain reactions, but not others. He discovered the chemical compound phenylhydrazine, which later proved to be very useful for a variety of purposes and has been found to induce eczema. His work included methods of managing the chemistry of carbohydrates, thanks in part to the use of phenylhydrazine. This

Emil Fischer (1852–1919), a German organic chemist, discovered caffeine and other related purines. He also studied the molecular structures of sugars and proteins. For his work he was awarded the 1902 Nobel Prize in Chemistry.

Hermann Emil Fischer might have gone into the family lumber business had his father had his way. But his father relented and allowed his son to study science after Emil proved unskilled in business. Fischer attended the chemistry lectures of August Kekulé at the University of Bonn but left to obtain his doctorate at Strasbourg, under the far more experimentally oriented dye chemist Adolf von Baeyer. Successively holding appointments at various German universities, Fischer ultimately rose to be chemistry professor at the University of Berlin. In Berlin he was instrumental in establishing the Kaiser Wilhelm Society (now the Max Planck Society) and its related institutes for chemistry and physics in 1911.

Purines and Sugars: Nobel Work

Early in his career Fischer discovered a family of bases called purines. Caffeine and theobromine—found in tea, coffee,
