Baron Philippe de Gunzbourg LdH CdG MBE (1904–1986) was a French aristocrat who became a Special Operations Executive agent during the World War II.
[citation needed] A relative, Aline de Gunzbourg, married the British writer and philosopher Isaiah Berlin.
In November 1942 after the German occupation of Vichy France, he made contact with Maurice Pertschuk, organiser of the PRUNUS network in Toulouse, and joined him as courier.
Philippe de Gunzbourg noted that Pertschuk had a reckless lack of security, with resistance leaders sharing tables in black-market restaurants in Toulouse and speaking in English, and on 12 April 1943 Pertschuk, Bloom, and several of their key colleagues were arrested.
In Losse (Landes), a stele inaugurated on 23 May 2002 quotes Philippe de Gunzbourg as part of a tribute to seven other agents brought to France nearby during five airdrops between August 1943 and April 1944: Maurice Southgate, organiser of the STATIONER network; four agents for the WHEELWRIGHT network of George Starr: Yvonne Cormeau, radio operator, Anne-Marie Walters, courier, Claude Arnault, saboteur instructor, and Denis Parsons, radio operator; two agents for the SCHOLAR network: Gonzague de Saint-Geniès, network organiser, and Yvonne Baseden, radio operator.
