Fritz Ullmann

Fritz Ullmann (born July 2 1875 in Fürth; died March 171939) was a German Chemist.

Ullmann started studying chemistry in Nurenberg, but received his PhD of the University of Geneva for work with Carl Gräbe in 1895. After some time in Geneva he went to Berlin in 1905. Ullmann taught technical chemistry during 1905-1913 and 1922-1925 at the Technischen Hochschule Berlin now Technische Universität Berlin, first as part of the ordinary teaching staff, later on as a Professor. In 1900 he introduced dimethyl sulfate as an alkylating agent. Between 1914 and 1922, when he was back in Geneva, he published the first edition of the "Enzyklopädie der Technischen Chemie" in 12 volumes ( ISBN 3-527-20142-4 ) in English the Ullmann's Encyclopedia of Industrial Chemistry, a publication that exists to this day. He was married to Irma Goldberg who was his assistant from 1905 to 1910 at his laboratory.

They named after themselves the following reactions: the Ullmann reaction, the Ullmann condensation, the Graebe-Ullmann synthesis, the Goldberg reaction and the illustrious Jourdan-Ullmann-Goldberg synthesis
