Just for interest, in David Owen's book "The Making of the Masters"...Hootie Johnson is quoted as saying that he believes the four most influential figures in American golf in this century (20th) have been Bobby Jones, Arnold Palmer, President Eisenhower, and Roberts.
As for being unhappy, it sounds like he had a helluva tough life as a youngster; accidentally burning down his family's house, helping his ailing mother out while his dad was away, and when he was 19 years old, had to suffer through his mom's own suicide.
He was, from the sounds of things, a "dictator" at Augusta. Yet, in reading the book, I see that there were times when his humourous side came to the forefront. Notably, when he was asked by the club's photographer Frank Christian to be a surprise guest in a video Christian shot of a man wearing a gorilla suit, running over the golf course, stealing clubs, and standing in a buffet line in the clubhouse. Roberts agreed to be in the final shot of the film, when the gorilla removed the mask, revealing himself to be Roberts. There are many anecdotes sprinkled throughout the book of Robert's humanitarian side, such as arranging an exhibition one year for local children, who were given free practice round tickets, and scheduled the practice round late in the afternoon so that it would not conflict with school.
Roberts also had the idea of using a portion of the tournament's proceeds to make golf available to soldiers stationed at Camp Gordon (Fort Gordon). The club built a practice range and huge putting green at Camp Gordon, and donated golf course items, and turf, maintenance equipment, and supplies.
