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.

Philippe Georges de Gunzbourg was born in Paris on 17 February 1904, the son of Baron Pierre de Gunzburg (the son of Baron Horace Günzburg), a banker, and Yvonne Deutsch de La Meurthe.^{[citation needed]} A relative, Aline de Gunzbourg, married the British writer and philosopher Isaiah Berlin.^[1]

He studied in Paris and Oxford.

He finished second in the 1933 Le Mans 24 Hours motor race.

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.^{[citation needed]} The wireless operator was Marcus Bloom.

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.^[2] They were possibly betrayed by double agent Roger Bardet.^[3] Pertschuk was deported to Buchenwald, Bloom to Mauthausen, and both were executed. The PRUNUS network collapsed after their arrest, though de Gunzbourg escaped and transferred to the WHEELWRIGHT network of George Starr, where he worked until liberation.^{[citation needed]}

After the war, he devoted himself to agriculture, agri-food, and prunes. He was one of the pioneers of France-Prune, and its first president.

He died on 10 July 1986, aged 82, and was buried in the cemetery of Saint-Léon.
