Graham Whettam (7 September 1927 – 17 August 2007) was an English post-romantic composer.
Whettam was born in Swindon, Wiltshire, and studied at St Luke's College, Exeter.
Though he never formally studied at a music school and was largely self-taught, several of his compositions had already been performed by major orchestras and soloists by his twenties. These include the Sinfonietta for Strings in 1951 at Kensington Palace; the Symphony No. 1 in the early 1950s by the Bournemouth Symphony Orchestra conducted by Charles Groves; the Concertino for oboe and string orchestra at the 1953 Proms performed by oboist Léon Goossens; and the Viola Concerto in 1954 at the Cheltentham Festival by violist Harry Danks and conductor Sir John Barbirolli. Other of his works had already been performed with the City of Birmingham Symphony Orchestra and the London Symphony Orchestra by conductors Basil Cameron, Meredith Davies, Sir Eugene Goossens, Willem van Otterloo, and Sir Malcolm Sargent, and by oboist Janet Craxton, clarinettist Jack Brymer, and horn player Dennis Brain. In 1959, the premiere of his first clarinet concerto was performed by Raymond Carpenter and the Bournemouth Symphony Orchestra conducted by Sir Charles Groves; this he considered his first mature work.
He was married to Rosemary Atkinson from 1948 until their divorce in 1958, at which time he moved to Coventry. While there, he married Janet Lawrence in 1959, and later founded and directed his own publishing company, "Meriden Music". In 1962 he wrote his first work to be critically considered a "masterpiece", Sinfonia contra timore (Symphony Against Fear), which was premiered three years later by the City of Birmingham Symphony Orchestra and conductor Hugo Rignold. Though Sinfonietta Stravagante (1964), performed by the Netherlands Philharmonic Orchestra and conductor Herbert Sourdant, and Sinfonia Concertante (1966), performed by the Northern Sinfonia and conductor Bryden Thomson, followed in rapid succession, Whettam did not continue to have the success of his youth; several of his works were premiered/published some time after their composition (cf. below), and some of his later works (such as the Promethean Symphony and the Symphony No. 5) still wait for a world premiere.
