Eugen Bamberger , (born July 19, 1857 in Berlin , † December 10, 1932 in Ponte Tresa , Switzerland ) was a German chemist who discovered the Bamberger rearrangement named after him .

Life

Bamberger, son of Sigismund Bamberger and Rosalie Bamberger, daughter of Jonas Jitzchak and Henriette Caro, studied from 1875 at the medical faculty of the Berlin University , but soon switched to the Ruprecht-Karls-University in Heidelberg and studied natural sciences. From 1876 to 1879 he studied chemistry in Berlin. On May 12, 1879, he was accepted into the Society of German Chemists by Carl Liebermann at the Royal Technical University of Charlottenburg for his doctoral thesis " About guanylsulfurea and some guanylguanidines " . The doctoral examination was held in the summer of 1880 by AW von Hofmann at theFriedrich Wilhelms University . In 1881 he stayed briefly with Carl Rammelsberg in the second institute of the university .

In the summer of 1882 he received an assistant and later post-doctoral post from Adolf von Baeyer , the former predecessor of Carl Liebermann in Berlin, at the Ludwig Maximilians University in Munich .

He completed his habilitation in 1891 and became an associate professor at the Ludwig Maximilians University in Munich . In 1893 he was appointed professor for general chemistry at the Polytechnic in Zurich , where he developed a lively research and teaching activity.

He maintained a friendly relationship with his student Felix Hoffmann and with Carl Duisberg , the research director of the paint factories vorm. Friedr. Bayer & Co. in Elberfeld.

A treacherous nerve ailment which, in addition to severe headaches, also restricted the use of his right arm, forced him to give up the chair in 1905, but he continued his research with restrictions. In a small laboratory he continued his scientific work with the help of a private assistant. When even this limited scientific work became impossible, Bamberger withdrew more and more to Ticino, where he died in Ponte Tresa in 1932.

Bamberger was married to Karoline Rosalie Marie Sertorius since 1888.

Bamberger's research on chemical reactions

Bamberger has published about 430 scientific papers. His main interest was the chemical process itself, the reaction mechanism of complicated conversions and their breakdown into individual phases. A chemical reaction was named after him: the Bamberger rearrangement is a chemical reaction that is used to synthesize para- hydroxyaniline derivatives from phenylhydroxylamine derivatives in the presence of strong aqueous acids.
