Jack Beaver (27 March 1900 – 10 September 1963) was a British film score composer and pianist.
In the early 1930s he played with the Michael Doré Trio and wrote some concert pieces, including the three movement Sonatina for piano.
He wrote music for Alfred Hitchcock's The 39 Steps (1935), and composed the pseudo piano concerto Portrait of Isla from the score for the 1940 Edgar Wallace film The Case of the Frightened Lady.
[2] Later in life Beaver was a regular contributor to the recorded music libraries, through which his march Cavalcade of Youth (1950) became widely known when it was used as signature tune for the BBC radio series The Barlowes of Beddington.
[3][4] Another example of his library music is Holiday Funfair (1954), performed by Dolf van der Linden And His Orchestra.
