Who won the first Palme dOr at Cannes?

The Palme d’Or (Golden Palm) is the highest prize awarded to the director of the best feature film at the annual Cannes Film Festival. It was introduced in 1955 by the organizing committee, and the first was awarded to director Delbert Martin Mann Jr for his film “Marty”. The Palme d’Or was established as the film festival’s highest award until 1964, when it temporarily resumed awarding Grand Prix due to copyright problems with the Palm. In 1975, the Palme d’Or was reintroduced and became the symbol of the Cannes Film Festival.
