Georg von Reisswitz

Georg Heinrich Rudolf Johann von Reisswitz (1794–1827) was a Prussian army officer. Reisswitz is regarded by many as the father of wargaming, as he developed the first wargaming system to be widely used as a serious tool for training and research. The particular genre of wargaming he developed is known in the English-speaking world as Kriegsspiel. It is characterized by high realism, an emphasis on the experience of decision-making rather than on competition, and the use of an umpire to keep the system flexible.
