In 1939, an average Joe named Homer Kelley played golf for the first time and scored 116 - a respectable score for a beginner but frustrating for a science-obsessed perfectionist like Kelley. He did not play again for six months, then carded a 77. He devoted the next 30 years to solving the science behind the perfect golf swing. Here, veteran journalist Scott Gummer brings to light the untold story of golf's most curious genius.
