Robert Lee McCollum (November 30, 1909 – November 5, 1967)was an American blues musician who played and recorded under the pseudonyms Robert Lee McCoy and Robert Nighthawk. He was the father of the blues musician Sam Carr. 　　Born in Helena, Arkansas, he left home at an early age to become a busking musician. After a period wandering through southern Mississippi, he settled for a time in Memphis, Tennessee, where he played with local orchestras and musicians, such as the Memphis Jug Band. A particular influence during this period was Houston Stackhouse, from whom he learned to play slide guitar and with whom he performed on the radio in Jackson, Mississippi.
