9. Arnold Palmer
The first golfer on this list, Arnold Palmer is a true icon of his sport. ‘The King’ won an incredible 62 PGA tour titles from 1955 to 1972 and just as significantly, he helped to change perceptions of the sport. Coming from a working-class background, the charismatic, plain-spoken Pennsylvanian was the son of a Country Club greenskeeper.
After the tragic death of his best friend Bud Worsham, he entered the US Coast Guard where he served for three years. At the training center in New Jersey, he built a nine-hole course where he continued to hone his skills. When his term of enlistment ended, he made the decision to turn pro.
