Alexander Murray Hannum (July 19th 1923, Los Angeles - January 18th 2002, San Diego) was a player and a professional trainer of tennis shoe. If its career of player in NBA does not attract a reputation out-standard to him, it is one of the two trainers to have gained a title in NBA (1958, 1967) and in ABA (1969), the other being Bill Sharman. He is elected trainer of the year in NBA in 1964, and 1969 in ABA.

He brings the Philadelphia Sixers to the title in 1967, with Wilt Chamberlain in his team, putting a term at the eight victories of sharpened Boston Celtics.
