Hyam 'Bumps' Greenbaum was an English conductor, violinist and composer, who, in 1936, became the world's first conductor of a television orchestra. He was friendly with many of his English music contemporaries, including Constant Lambert, Alan Rawsthorne, and William Walton, and often helped them with technical advice on orchestration. His brother Bernard (1917–1993) was an artist, and his sister was the pianist and composer Kyla Greenbaum (1922–2017).
