Beckett translated all of his works into English himself, with the exception of Molloy, for which he collaborated with Patrick Bowles. The success of Waiting for Godot opened up a career in theatre for its author. Beckett went on to write successful full-length plays, including Fin de partie (Endgame) (1957), Krapp's Last Tape (1958, written in English), Happy Days (1961, also written in English), and Play (1963). In 1961, Beckett received the International Publishers' Formentor Prize in recognition of his work, which he shared that year with Jorge Luis Borges.
The 1960s were a time of change for Beckett, both on a personal level and as a writer. In 1961, he married Suzanne in a secret civil ceremony in England (its secrecy due to reasons relating to French inheritance law). The success of his plays led to invitations to attend rehearsals and productions around the world, leading eventually to a new career as a theatre director. In 1957, he had his first commission from the BBC Third Programme for a radio play, All That Fall. He continued writing sporadically for radio and extended his scope to include cinema and television. He began to write in English again, although he also wrote in French until the end of his life.
