Cromwell Everson (28 September 1925 – 11 June 1991) was primarily known as a composer during his lifetime. He was brought up as an Afrikaner by his mother, Maria De Wit and father, Robert Everson. He continued this tradition and all his children were brought up as Afrikaners.
Everson wrote the first Afrikaans opera, and most of his other vocal works were in Afrikaans. His works consist of five sonatas, a trio, an opera, a set of inventions, four song-cycles, a piano suite, miscellaneous movements for the piano and guitar and an incomplete symphony and string quartet.
