Leroy Eliot “Slam” Stewart (September 21, 1914 – December 10, 1987) was an American jazz double bass player, whose trademark style was his ability to bow the bass (arco) and simultaneously hum or sing an octave higher. He was a violinist before switching to bass at the age of 20. Stewart was born in Englewood, New Jersey, United States and began playing string bass while attending Dwight Morrow High School. While attending the Boston Conservatory, he heard Ray Perry singing along with his violin. This gave him the inspiration to follow suit with his bass. In 1937, Stewart teamed with Slim Gaillard to form the novelty jazz act Slim and Slam. The duo’s biggest hit was “Flat Foot Floogie (with a Floy Floy)” in 1938.
