Biography: Edward F. Davis (March 2, 1922 – November 3, 1986),known professionally as Eddie "Lockjaw" Davis, was an American jazz tenor saxophonist. It is unclear how he acquired the moniker "Lockjaw" (later shortened to "Jaws"): it is either said that it came from the title of a tune or from his way of biting hard on the saxophone mouthpiece.
