Benjamin Frankel (31 January 1906 – 12 February 1973) was a British composer. His best known pieces include a cycle of five string quartets, eight symphonies, and concertos for violin and viola. He was also notable for writing over 100 film scores and working as a big band arranger in the 1930s. During the last 15 years of his life, Frankel also developed his own style of 12-note composition which retained contact with tonality.
