Best known as the only golfer to win all four Major Championships, the (pre Masters) "Grand Slam", in the same calendar year, Bobby Jones is one of the game’s greatest ever players. The American may have retired from playing competitive golf at just 28 years of age, but he left a lasting legacy, winning the US Open four times and the Open Championship thrice.
The man from Atlanta claimed his first Major Championship, the 1920 US Open, at the age of just 18. Ten years later he completed the “impregnable quadrilateral”. What made his achievements all the more impressive was that he continued to study whilst he competed, and he earned a degree in mechanical engineering from Georgia Tech. He later converted to law and passed the Georgia bar exam in 1926.
