John Lenwood (Jackie) McLean was an alto saxophonist, composer, bandleader and educator, born in New York City.
His father, John Sr., who died in 1939, played guitar in Tiny Bradshaw's orchestra. After his father's death, his musical education was continued by his godfather, by his stepfather, who owned a record store, and by several noted teachers. He also received informal tutoring from neighbours Thelonious Monk, Bud Powell, and Charlie Parker. During high school he played in a band with Kenny Drew, Sonny Rollins, and Andy Kirk Jr. (the tenor saxophonist son of Andy Kirk).
