Julius Bernhard Friedrich Adolph Wilbrand (22 August 1839 – 22 June 1906)[1] was a German chemist. Born in Gießen to Franz Joseph Julius Wilbrand and Albertine Knapp,[1] he discovered trinitrotoluene in 1863,[2] [3] but the compound's use as an explosive was not developed until later. Wilbrand obtained trinitrotoluene or TNT by the nitration of toluene.
