Ernest Berk (12 October 1909 – 30 September 1993) was a dancer, modern dance choreographer and composer of electronic music.

Born in Koln, Germany, Berk received his musical education from the Rheinische Musikschule, and was taught dance by Mary Wigman and the Brazilian dancer Chinita Ullmann.

[3] During this period he founded the Modern Dance Group in London and produced Buddha the Enlightened, a ballet commissioned by the poet John Masefield.

[7] His music was often used to accompany his own expressionist dance works, but he soon also began producing electronic soundtracks for theatre, television (such as the 1963 BBC drama A Little Bit Of Gold Said "Jump")[8] and film.

[16] They separated in the 1960s, and Lotte Berk went on to develop methods of exercise that attracted celebrity interest from Britt Ekland, Barbra Streisand and Joan Collins.

[10] Together they formed the Dance Theatre Commune in 1970, and taught at the Guildhall School of Music and Drama and at the Stanhope Institute for adult education.
