Bobby Jones was arguably the Mozart of the golf world, winning his first children's tournament at the age of 6 and making it to the third round of the U.S. Amateur Championship at just 14. Famously, he remained an amateur throughout his impressive career (he won 13 majors). In 1930 Jones took his third and final Open championship at the Royal Liverpool Golf Club. But that barely tells the story, as the triumph was part of a historic achievement: winning all four legs of the Grand Slam. Back then, the British and U.S. Opens, the British Amateur and the U.S. Amateur championships comprised the championship quartet. No player had won the Slam before, and no one has done it since. (Tiger Woods has come the closest, winning four in a row within a 12-month period over two years.)
