Stoppard wrote short radio plays in 1953–54 and by 1960 he had completed his first stage play, A Walk on the Water, which was later re-titled Enter a Free Man (1968). He noted that the work owed much to Robert Bolt's Flowering Cherry and Arthur Miller's Death of a Salesman. Within a week after sending A Walk on the Water to an agent, Stoppard received his version of the "Hollywood-style telegrams that change struggling young artists' lives." His first play was optioned, staged in Hamburg, then broadcast on British Independent Television in 1963. From September 1962 until April 1963, Stoppard worked in London as a drama critic for Scene magazine, writing reviews and interviews both under his name and the pseudonym william Boot (taken from Evelyn Waugh's Scoop). In 1964, a Ford Foundation grant enabled Stoppard to spend 5 months writing in a Berlin mansion, emerging with a one-act play titled Rosencrantz and Guildenstern Meet King Lear, which later evolved into his Tony-winning play Rosencrantz and Guildenstern Are Dead. In the following years, Stoppard produced several works for radio, television and the theatre, including "M" is for Moon Among Other Things (1964), A Separate Peace (1966) and If You're Glad I'll Be Frank (1966). On 11 April 1967 – following acclaim at the 1966 Edinburgh Festival – the opening of Rosencrantz and Guildenstern Are Dead in a National Theatre production at the Old Vic made Stoppard an overnight success. Jumpers (1972) places a professor of moral philosophy in a murder mystery thriller alongside a slew of radical Gymnasts, and Travesties (1974) explored the 'Wildean' possibilities arising from the fact that Vladimir Lenin, James Joyce, and Tristan Tzara had all been in Zurich during the First World War. In his early years, he also wrote extensively for BBC radio, often introducing surrealist themes. He has also adapted many of his stage works for radio, film and television winning extensive awards and honours from the start of his career. His latest original radio production, Darkside (2013), has been written for BBC Radio 2 to celebrate the 40th anniversary of Pink Floyd's album, The Dark Side of the Moon.
