Bobby Jones (Robert Tyre Jones Jr. March 17, 1902 – December 18, 1971) was one of the most influential figures in the history of golf.
Bobby was a lawyer by profession. He founded and helped design the Augusta National Golf Club. He also co-founded the Masters Tournament.
He was the most successful amateur golfer ever to compete at international level.
Fewer major tournaments existed when Bobby Jones was at his peak - certainly The Masters didn't exist until he created it after his competitive playing days were over!.
Because of this the Amateur Championships of Britain and the USA are generally accepted as Major tournaments of the time.
