Edgar Brandt was a French iron worker born in 1880. He was a prolific weapons designer and head of a company that designed 60mm, 81mm and 120mm mortars that were very widely copied throughout and subsequent to World War II. He also invented discarding-sabot artillery shells, and contributed substantially through his development of HEAT rifle grenades to the development of effective HEAT-warhead weapons for infantry anti-tank use.
