 Charlie Sifford decided that he was going to integrate the game of golf just as Jackie Robinson had done in the game of baseball. Sifford had won the National Negro Open five straight times, from 1950 to 1956, and in 1957 he won the Long Beach Open. In 1960, when he was 39 years old, Sifford, after years of trying, earned a PGA player card, and a year later, under pressure from the California Attorney General, the PGA of America dropped its Caucasian-only membership clause. Sifford had finally broken the color barrier and became a member of the Tour in 1961. Despite his advanced age, he went on to win two official money events in 1967 and in 1969. He was also the first African-American to win the PGA Seniors Championship in 1975. In 2004, Sifford became the first African-American inducted into the World Golf Hall of Fame.
