Thomas Lee Flanagan 16 March 1930?16 November 2001) was an American jazz pianist born in Detroit, Michigan, particularly remembered as an accompanist of Ella Fitzgerald. He played on a number of critically acclaimed recordings, such as John Coltrane's Giant Steps, Sonny Rollins' Saxophone Colossus and The Incredible Jazz Guitar of Wes Montgomery.
The Tommy Flanagan Trio (with bassist Wilbur Little and drummer Elvin Jones) released their first album, Tommy Flanagan Trio Overseas, in 1957. As an accompanist, Flanagan worked with Ella Fitzgerald from 1963?65 and 1968?78. But beginning in 1975, Flanagan began once again to perform and record as a leader. He continued to work with other players, however, forming a trio with Tal Farlow and Red Mitchell, among other projects.
