Leonard Salzedo (24 September 1921 – 6 May 2000) was an English composer and conductor of Spanish descent. He composed over 160 works, including 18 film scores, 17 ballets, ten string quartets and two symphonies. Salzedo also wrote many film scores, including several for Hammer Films, amongst them the war movie The Steel Bayonet (1957) and the horror film The Revenge of Frankenstein (1958).[10] And his music became widely used as production music for television and radio. The fanfare which forms the first six bars of Salzedo's Divertimento for three trumpets and three trombones, opus 49 (1959), was used as the theme tune for the Open University's educational programmes on BBC television and radio from the 1970s to the 1990s. Another of his tunes, Guadalajara, was used by the BBC to accompany their "pie chart" schools' presentation during the 1960s and early 1970s, up until 1973.
