Philippe Albert de Crevoisier, Baron de Vomécourt, code names Gauthier and Antoine, was an agent of the United Kingdom's clandestine Special Operations Executive (SOE) organization in World War II. He was the organiser (leader) of the Ventriloquist network from May 1941 until the liberation of France from Nazi German occupation in September 1944. The purpose of SOE in occupied France was to conduct espionage, sabotage and reconnaissance. SOE agents allied themselves with French Resistance groups and supplied them with weapons and equipment parachuted in from England. The primary area of Vomécourt's activity was in the Sologne region about 160 kilometres (99 mi) south of Paris. Philippe's older brother Jean and younger brother Pierre were also members of the French Resistance.
