Gerhard Schrader (1903–1990) was a German chemist known for his discovery of effective insecticides such as parathion and bladan, the first fully synthetic contact insecticide. While working at IG Farben, Schrader accidentally synthesized deadly nerve agents including Tabun and Sarin, the latter partially named after him. Born near Wendeburg, he studied chemistry at Braunschweig University of Technology before his employment at Bayer AG. During World War II, Schrader’s teams developed additional organophosphate nerve agents, including Soman and Cyclosarin, under the Nazi regime.
