Alain Jessua was a French film director and screenwriter who directed ten films between 1956 and 1997.
Léon la lune (1956), a film documenting the life of the ‘clochard‘ of the title, was Alain Jessua’s first film and it won the influential Prix Jean Vigo in 1957. The short film was inspired by Jean-Paul Clébert’s book Paris insolite (1952), the first of a series of realist photojournalistic books depicting the underworld in Paris. Clébert’s friends Jacques Yonnet and Robert Giraud wrote their own tales of the vagabond life on the streets of Paris; Yonnet wrote Paris Noir (1954), and Giraud’s Le Vin des rues (1955). The three frequented the same haunts as the youths of Letterist International, and this scene would become the subject of Ed van der Elsken’s photonovel Love on the Left Bank (1956), the most popular depiction of Parisian bohemian bar life.
