Wilhelm Koenigs
Wilhelm Koenigs (born April 22, 1851 in Dülken near Mönchengladbach , † December 15, 1906 in Munich ) was a German chemist and professor at the Ludwig Maximilians University in Munich .
Koenigs was the son of the entrepreneur Franz Wilhelm Koenigs (May 8, 1819 - 1882) and studied from 1868 at the Gewerbeakademie Berlin and the Bergakademie Berlin . He turned to chemistry and worked in 1871 with Carl Remigius Fresenius and at the University of Bonn , where he received his doctorate in 1875 after having worked in Heidelberg in 1874/1875. After completing his doctorate, he briefly attended the University of Berlin , the Polytechnic in Zurich and, from 1876, at the Ludwig Maximilians University in Munich, where he completed his habilitation in 1881 and was appointed associate professor in 1892 .
He mainly dealt with quinoline alkaloids and quinuclidine derivatives and their structure elucidation (the well-known quinine consists of quinoline and quinuclidine). In 1879 he synthesized quinoline from N -allylaniline and thus clarified the structure of quinoline. The Koenigs-Knorr method is named after him and his colleague Eduard Knorr (1867–1926) .
In 1900 Koenigs was elected a member of the Leopoldina . He died in 1906 at the age of 55 and was buried in the family crypt in the Melaten cemetery in Cologne (MA, between lit. P + Q). His older brothers were the bankers Felix Koenigs and Ernst Friedrich Wilhelm Koenigs .
