Bernard Hartwell "Step-Buddy" Anderson (1919–1997) was an American jazz trumpeter from Oklahoma City, Oklahoma. Having studied music at school under Zelia N. Breaux, Anderson was a professional musician by 1934, playing with the Ted Armstrong band in Clinton, Oklahoma. In the late 1930s he was a member of the Xavier University jazz band in New Orleans. Shortly after joining the Billy Eckstine Orchestra in 1944, he caught tuberculosis and was medically advised to abandon the trumpet. He played his own unique style of piano after putting down the trumpet.
