Communist, resistance fighter, deportee, Marie-Claude Vaillant-Couturier is one of the great heroines of the 20th century. Nicknamed Maïco, she became a photojournalist and embraced the class struggle at the same time as she fell in love with one of the figures of the Popular Front, Paul Vaillant-Couturier. During World War II, she joined the Resistance and later gave decisive testimony at Nuremberg.
