Harold “Happy” Hairston (May 31, 1942 – May 1, 2001) was an American professional basketball player who played for the Los Angeles Lakers of the NBA. He was a member of 1971–72 NBA championship Lakers team that won 33 games in a row, a record not duplicated in any other American professional sport. Hairston was a 6’7″ (200 cm) 225 lb (102 kg) forward. He was born in Winston-Salem, North Carolina. Hairston attended Erasmus Hall in Brooklyn, New York. He played college basketball at New York University from 1962 to 1964. He played professionally for the Cincinnati Royals and Detroit Pistons before arriving at the Lakers in 1969. In 1971-72, Hairston grabbed 1,045 rebounds and his teammate Wilt Chamberlain pulled down 1,572. It remains the only season in NBA history that two teammates grabbed more than 1,000 rebounds each. Hairston led the Lakers in both rebounds and field goal percentage during the 1973-74 and 1974-75 seasons, and set an NBA record for most defensive rebounds in a quarter with 13 (vs. the Philadelphia 76ers, November 15, 1974).
