Robert Tyre Jones Jr. (March 17, 1902 – December 18, 1971) was an American amateur golfer who was one of the most influential figures in the history of the sport; he was also a lawyer by profession. Jones founded and helped design the Augusta National Golf Club, and co-founded the Masters Tournament. The innovations that he introduced at the Masters have been copied by virtually every professional golf tournament in the world.
Jones was the most successful amateur golfer ever to compete at a national and international level. During his peak from 1923 to 1930, he dominated top-level amateur competition, and competed very successfully against the world's best professional golfers. Jones often beat stars such as Walter Hagen and Gene Sarazen, the era's top pros.
