Julius Tröger

Who was Julius Tröger?

Julius Tröger was a German chemist.

Tröger studied at the University of Leipzig from 1882 till 1888. During his Ph.D. he synthesized in 1887 2,8-Dimethyl-6H,12H-5,11-methanodibenzo-[b,f][1,5]diazocine from p-toluidine and formaldehyde. This substance is now known as the Tröger's base. Because he was not able to give a structure of the new compound Johannes Wislicenus, the new director of the department, assigned a mediocre grade for Trögers thesis. It took another 48 years to confirm the structure of Tröger's base. In 1888 he started working at the University of Braunschweig where he stayed until his retirement in 1928. Tröger died in Brunswick.
