William Christopher Handy (November 16, 1873 – March 28, 1958) was an American blues composer and musician.
Handy remains among the most influential of American songwriters. Though he was one of many musicians who played the distinctively American form of music known as the blues, he is credited with giving it its contemporary form. While Handy was not the first to publish music in the blues form, he took the blues from a regional music style with a limited audience to one of the dominant national forces in American music.
Handy was an educated musician who used folk material in his compositions. He was scrupulous in documenting the sources of his works, which frequently combined stylistic influences from several performers.
