Jouhaux was born in Pantin, Seine-Saint-Denis, France. Jouhaux's father worked in a match factory in Aubervilliers. His secondary schooling ended when his father's earnings were stopped by a strike. He gained employment at the factory at age sixteen and immediately became an important part of the union. In 1900, after serving a brief mandatory military sentence in French Algeria, Jouhaux joined a strike against the use of the white phosphorus that blinded his father, was dismissed, and worked at a succession of jobs until union influence saw him reinstated.
In the years before World War II, Jouhaux organised several mass protests, and the organization he led protested against the war. However, once the war started, Jouhaux supported his country and believed that a Nazi Germany victory would lead to the destruction of democracy in Europe. During the war, he was arrested and imprisoned in Buchenwald concentration camp, later moved to the Castle Itter before being freed by American and German troops in the 1945 battle there.
After the war, Jouhaux split from the CGT to form the social-democrat Workers' Force (CGT-FO). In 1951, he was awarded the Nobel Peace prize.[1]
"I would not go so far as to say that the French trade unions attached greater importance to the struggle for peace than the others did; but they certainly seemed to take it more to heart." Léon Jouhaux[8]
