If you don't know about Charlie Sifford, you should.
Until 1961, the PGA Tour had a "Caucasian Only" clause. It's hard to believe in 2015, but less than 60 years ago people were excluded from playing at the highest level solely because of the color of their skin. Much like Jackie Robinson in baseball, Charlie Sifford wasn't the first African-American golfer. He may not even have been the best at the time. But he was the one who broke the color barrier on the PGA TOUR.
By the time Sifford was allowed to measure his skill against other pros on the PGA TOUR, he was 38 (Tiger and his back are now 39). Sifford won but twice on the TOUR but his contributions and sacrifices went far beyond that. Charlie Sifford, in 1960, opened up what was then a very exclusionary sport to a new audience. Sifford endured insults, threats, and galleries who would occasionally kick or throw his ball into the rough, woods, and other bad lies.
Though there is still work to do to make golf more inclusive, Sifford's contributions made it unlikely that anyone will endure what he did in the future, and we should all take notice and honor him.
