Hyam 'Bumps' Greenbaum (12 May 1901 – 13 May 1942) was an English conductor, violinist and composer, who, in 1936, became the world's first conductor of a television orchestra.[1] 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.[2] His brother Bernard (1917–1993) was an artist,[3] and his sister was the pianist and composer Kyla Greenbaum (1922–2017).
