Allan Robertson (1815-1859)

Considered to be the first "professional golfer", making a living by playing for bets, caddying and making balls and clubs. Born in St. Andrews, he was the first ever to break the score of 80 on The Old Course, and it is said, was never beaten as an individual when money was on the line. Since he was considered the best golfer alive, following his death, the R&A established The Open Championship in 1860 to determine his successor.
