During his career, Sifford won the UGA National Negro Open six times but was excluded from PGA competition due its "Caucasian only" policy. (Video via WEWS)
But Sifford was adamant about changing that, even though he received death threats in the process. In 1961, Sifford broke down golf's color barrier and became the first black man to earn a PGA Tour card. (Video via Back9Network)
Sifford went on to win two PGA Tour championships — one in 1967 and the other in 1969. He also became the first black man inducted into the World Golf Hall of Fame in 2004.
According to the World Golf Hall of Fame, Sifford found inspiration from Jackie Robinson and even spoke with him about his plans to break the color barrier in golf.
"[Robinson] asked me if I was a quitter. He said, 'OK, if you're not a quitter, go ahead and take the challenge. If you're a quitter, there's going to be a lot of obstacles you're going to have to go through to be successful in what you're trying to do.' ... I made up my mind I was going to do it. I just did it. Everything worked out perfect, I think," said Sifford.
