Remy was born in a small French town to Catholic parents. In 1913, after studying law at the University of Paris, he joined the Tallandier publishing house in Paris. During World War I he served in the French army and was wounded five times. He returned to work at Tallandier after the war, and in 1919 he married Germaine Tallandier, the daughter of the owner. They had five children whom they raised as devout Catholics.
1933-39: In 1935 Remy became the mayor of Avon, a small town about 35 miles southeast of Paris. Remy was proud of his town, which was famous for its royal palace and nearby forest of Fontainebleau. A strongly patriotic Frenchman, he distrusted Germany after Hitler came to power there in 1933.
1940-44: In June 1940 the Germansdefeated France and occupied Avon on the 16th. Remy resolved to remain mayor and became active in a resistance group called "Velite Thermopyles." He gave financial support to Jewish and other writers whose works could no longer be published. He sheltered some Alsatian Jews in Dordogne, where he owned a home. Using his office as mayor to protect Jews and other fugitives, he provided them with false papers, and helped them flee south to the unoccupied part of France, or to safe houses.
On May 4, 1944, Remy was arrested in Avon by the Gestapo upon returning from a business trip to Paris. He died in theNeuengamme concentration camp on March 15, 1945.
