Pierre Louis Le Chêne LdH CdG MBE (14 June 1900 – 1979) was a British-born French Special Operations Executive agent during the Second World War.
During the German invasion in 1940 Pierre, his older brother Henri, and his sister-in-law Marie-Thérèse, left France for England on the last boat leaving from Bayonne.
On the night of 30 April/1 May 1942 he was parachuted near Loches to assist Edward Zeff in the Lyons area, as a radio operator of the SPRUCE network, successively headed by Georges Duboudin and Robert Boiteux.
He was taken to the police station in Lyons for two weeks, then handed over to the Sicherheitsdienst headquarters in Avenue Foch in Paris, then moved to Fresnes prison.
After 10 months he was transferred to Gusen I where he endured even worse physical and mental torment: sorting internees for the gas chamber, mass executions, and accumulation of corpses.
