Short Answer
Early Life and Path to the SOE
Claude Marie Marc Boucherville de Baissac was born on 28 February 1907 in Curepipe, Mauritius [1, 2]. Born to British aristocratic landowners, he received his education at the Lycée Henri-IV in Paris [2]. Before the outbreak of the Second World War, de Baissac’s professional life was varied; he worked for a mica mining company in Madagascar before returning to France to pursue a career in advertising [2].
Following the German invasion of France in May 1940, de Baissac fled Paris for the south of the country [2]. His attempts to reach the United Kingdom were fraught with difficulty; he crossed the Pyrenees into Spain, where he was imprisoned for seven months before eventually securing passage to Britain [2]. Upon his arrival, he was recruited into the Special Operations Executive (SOE) in February 1942 [2, 4].
Training and Deployment
De Baissac was assigned to the SOE’s French Section (F Section) as a Circuit Organiser [2]. He underwent training alongside other notable agents, including Francis Suttill, Harry Peulevé, and Roger Landes [2].
On 30 July 1942, de Baissac and his wireless operator, Harry Peulevé (codename ‘Jean’), were parachuted into France via a Halifax bomber [3, 4]. The deployment was marred by a technical error: the aircraft dropped the men too low over Nîmes, resulting in injuries for both [3]. While Peulevé suffered a severe leg fracture that necessitated his immediate return to England, de Baissac suffered a broken ankle but remained in the field to begin his mission [3, 4].
The Scientist Network
Operating under the codenames ‘David’, ‘Denis’, and ‘Clement’, de Baissac established the Scientist network in the Bordeaux area and southwestern France [1, 2]. His primary objectives were to organize and supply the French Resistance with arms, conduct reconnaissance, and gather intelligence [1].
Personnel and Expansion
To support the growth of the network, additional agents were deployed to the region. On 2 November 1942, Roger Landes (codename ‘Aristide’) was parachuted in to assist, followed by Mary Herbert, who arrived by boat on 8 November to serve as a liaison agent [4].
The network’s capacity grew rapidly through collaboration with existing local resistance groups. In January 1943, a Mauritian national known as Elme informed de Baissac of a strong resistance group led by André Grandclement [4]. The integration of Grandclement’s group provided Scientist with significant manpower and local expertise. By March 1943, de Baissac reported to SOE headquarters in London that he had approximately 11,000 men under his command [3].
Operational Focus
The Scientist network divided its efforts between two primary environments: the urban center of Bordeaux and the rural Landes region [3]. In the port of Bordeaux, the network focused on targeting German submarine pens, while the rural elements focused on sabotage and guerrilla activity [3].
Security Risks and the Prosper Connection
The Scientist network maintained close ties with the Prosper network in Paris, led by Francis Suttill [3]. However, this connection brought significant risk. In May 1943, Suttill warned de Baissac that he suspected Henri Dericourt, a key member of the Prosper network, of being a double agent for the Germans [3].
The fears were realized on 23 June 1943, when the Gestapo captured Suttill and several senior members of the Prosper group [3]. This wave of arrests created a precarious security situation for all linked networks in France, including Scientist.
Post-War Life and Legacy
Claude de Baissac survived the war and was recognized for his service with the Distinguished Service Order (DSO) and bar, as well as the Croix de Guerre (CdeG) [1]. He eventually married Mary Katherine Herbert [1]. De Baissac died on 22 December 1974 at the age of 67 [1].
