Fernande Grudet (born 6 July 1923), also known as Madame Claude, is the most famous French procurer. In the 1960s she was the head of a French network of call girls who worked especially for dignitaries and civil servants.
Born on 6 July 1923 in Angers, France, Fernande Grudet was reared in a convent by nuns. After acting as an agent of the Resistance during the German Occupation of France during World War II and doing several other jobs, she created her exclusive prostitution network in Paris during the 1960s.
Her clientelle included not only political figures, but also members of the Mafia, as well as police administrators who ensured her protection. One of her friends was the gangster, Pierre Loutrel alias Pierrot le Fou.
During the 1980s she returned to France, convinced that she was protected by new tax laws, and set up a new prostitution organization. The French Treasury, however, prosecuted her in 1986. In 1992 she was sentenced to a term in Fleury-Mérogis Prison for procuring.
