Lemuel A. Davis, known as Lem Davis, was an American jazz alto saxophonist born on June 22, 1914, in Tampa, Florida, and passed away on January 16, 1970, in New York. Davis was a prominent figure in the swing music scene, particularly during the 1940s and 1950s. He began his career in the late 1930s with Charlie Brantley's Collegians and first recorded with the Harlem Indians in 1941. Davis gained recognition in the early to mid-1940s through his performances with notable musicians such as Nat Jaffe, Coleman Hawkins, and Eddie Heywood.

Throughout the 1940s, Davis played with various jazz groups and was part of the Coleman Hawkins septet in 1943. He also recorded as a leader in 1945-1946 and again in 1951. In 1953, he appeared on Buck Clayton's recording of "The Hucklebuck." During the 1950s, Davis continued to perform in New York City, although his recording activity decreased. He was associated with several groups, including Billy Kyle's Big Eight and Eddie Heywood And His Orchestra, and led his own band featuring Emmett Berry on trumpet. Despite recording less in his later years, Davis remained an influential figure in the jazz community until his death.
