Co-creator, with Bobby Jones, of the Augusta Nation golf tournament helped improve the Masters tour and the game itself.
Running the Masters with an iron first and behind a wall of secrecy, he instituted the over-under par system, the twosome pairing system, and grandstands for viewers.
He was also known to be a racist, once saying that 'As long as I'm alive, golfers will be white, and caddies will be black.'
He was born in Morning Sun, Iowa, growing up in a troubled family: both his parents were financially struggling and in poor health.
He successfully kept black players out of the Masters Tour until 1975, when Lee Elder competed.
