Gaston Bodart (1867–1940) was a military historian, statistician, and government official. He was born in 1867 in Vienna, Austria. He achieved distinction for his analysis of casualties of war in Austria's wars, from the Thirty Years War to the Russo-Japanese War in 1905 and for many years his studies of military casualties remained the standard in the literature. As an assistant commissioner of the Imperial and Royal Commission, he also helped to organize Austria's presentations at various world fairs and exhibitions.
