Frederick Craig Riddle OBE (20 April 1912 – 5 February 1995) was a British violist. He was considered to be in the line from Lionel Tertis and William Primrose, through to the violists of today such as Lawrence Power.^[1]

Frederick Riddle was born in Liverpool in 1912. He studied at the Royal College of Music (RCM) in London from 1928 to 1933. He had a solo career while playing with the London Symphony Orchestra from 1933 to 1938. In 1938, was appointed principal viola with the London Philharmonic Orchestra.

Riddle was distinguished as a chamber music player and a concerto soloist. He made the first recording of William Walton's Viola Concerto, on 6 December 1937,^[3] with the composer conducting.^[4] He was recommended for this recording by Lionel Tertis. He made some revisions to the concerto, with Walton's approval.^[5] Although Walton conducted the work many times with leading soloists such as Tertis and William Primrose, the interpretation he liked above all others was Riddle's.^[6] He also performed the work in concert under Beecham.^[2]

Riddle was married twice, and had three daughters. He was appointed an Officer of the Order of the British Empire (OBE) in 1980.^[4] His first wife was soprano, conductor, and voice teacher Audrey Langford.^[7] In 1946, he married soprano singer Helen Clare.^[8]
