Early Life and Education

François-Yves Guillin was born on September 7, 1921, in Orléans, France, and spent part of his youth in Bourg-en-Bresse, where he became involved in resistance activities during World War II.

Involvement in the Resistance

While still a student at the Lalande High School in Bourg-en-Bresse, Guillin engaged in Gaullist propaganda as early as June 1940, showing an early commitment to the French Resistance.

Meeting with General Delestraint

In September 1940, Guillin met General Charles Delestraint, who was staying at his family home. This connection led Guillin to become involved in clandestine activities with Delestraint and his officer colleagues.

Medical Studies and Resistance Work

Guillin left high school in June 1941 to begin medical studies, but in 1942 he became a liaison agent for Delestraint in the Resistance, using the pseudonym Mercure. Later, he served as Delestraint’s secretary after the general was appointed head of the Secret Army.

After Delestraint's Arrest

Following Delestraint’s arrest by the Gestapo in Paris in 1943, Guillin evaded capture and joined the Maquis, a network of French resistance fighters operating in rural areas.

Postwar Career and Historical Work

After the war, Guillin completed his medical training and became a rheumatologist. He also dedicated himself to preserving the memory of General Delestraint, eventually earning a doctorate in history and publishing a thesis on the general in 1995.

Awards and Recognition

Guillin received several honors for his service, including the Knight of the Legion of Honour, the Cross of War 1939-1945, and the Cross of the Combatant, among others. He passed away on October 18, 2020, in Sainte-Foy-lès-Lyon.
