About Léon Geismar
Lived 1895 – 1944 (aged 48). Léon Geismar was a French colonial administrator.
Léon Geismar (1895–1944) was a French politician and colonial governor of French West Africa.
Early life He was born in Alsace to a pious Jewish family. His father was a winemaker, and his ancestors included General Gédéon Geismar.
Life and career He initially served for the German army in World War One, but deserted to France in September 1914. He received several awards for his actions during the war, including the Escapees' Medal and the Volunteer Combatant's Cross.
After the war ended, Geismar studied for university and then moved to Dakar shortly after. His importance eventually grew to the point where he became Governor General of French West Africa. He received several honours during his time in Africa, including the Black Star, Dragon of Annam, and finally a Knight of the Legion of Honour, the highest order of merit in France.
Under the Vichy regime, Geismar was subjected to extreme persecution, and told by authorities that he would have to give up all his posts within a month. He was then demoted from Governor general to Treasurer for Ivory Coast.

He was married to a Malagasy Catholic, Marguerite Mouneyres, a descendant of Ranavalo III, and had one daughter. Geismar converted to Catholicism after marriage, but was still treated as a Jew by Vichy authorities. Geismar was fluent in six languages (including French, German, Hausa, and English) and had at least some knowledge of Italian, Portuguese, and Dutch.
