Essay on Hermann Emil Fischer: The Fischer esterification

1185 Words 5 Pages
Born Hermann Emil Louis Fischer in Germany, Fischer was best known for his work in the field of chemistry, including the study of sugars and purines . He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms, and discovered the Fischer esterification, a special type of esterification by refluxing a carboxylic acid with an alcohol in the presence of an acid catalyst .
Fischer attended the University of Strasbourg in 1872, and earned a doctorate in chemistry with his study of phenolphthalein under Professor Adolf von Baeyer. He was a 1902 recipient of the Nobel Prize in Chemistry, as well as many other awards.
Fischer was born in Euskirchen, Germany on October 9th, 1852. He was the only child of a German

Fischer earned his doctorate under von Baeyer in 1874, and finally decided to devote his life to chemistry. With his study of the phthalein dyes, he was appointed assistant instructor at the university. Also in 1874, Fischer obtained his Ph.D. in chemistry at Strasbourg with his thesis on fluoresceine and orcin-phthalein. During his time as assistant instructor, he discovered the first hydrazine base , phenylhydrazine , and showed its relationship to hydrazobenzene . This discovery was considered accidental, but greatly influenced Fischer’s later work.
In 1875, von Baeyer was asked to succeed Professor Leibig at the University of Munich, Germany. Fischer accompanied him there to become his assistant in organic chemistry. During this time, Fischer discovered the substance phenylhydrazine , and invented the Fischer Indole Synthesis which led to his later research on sugars. Fischer continued to work on the hydrazines, and with his cousin, worked out a new theory of the constitution of dyes from triphenylmethane .
Later, in 1879, Fischer was appointed Associate Professor of Analytical Chemistry at the university. He was also offered many other positions, including the Professor of Chemistry for the University of Erlangen in 1881, which he accepted. He was also offered to become an assistant to Victor Meyer, but had to decline due to gastritis, which had attacked him again. During his time at Erlangen, he studied the active ingredients of tea,
