Arnold Daniel Palmer (September 10, 1929 – September 25, 2016) was an American professional golfer who is widely regarded as one of the greatest and most charismatic players in the sport's history. Since embarking on a professional career in 1955, he won numerous events on both the PGA Tour and the circuit now known as PGA Tour Champions. Nicknamed "the King", Palmer was one of golf's most popular stars and seen as a trailblazer, the first superstar of the sport's television age, which began in the 1950s.
Palmer's social impact on golf was unrivaled among fellow professionals; his modest origins and plain-spoken popularity helped change the perception of golf from an elite, upper-class pastime of private clubs to a more populist sport accessible to middle and working classes via public courses. Palmer, Jack Nicklaus, and Gary Player were "The Big Three" in golf during the 1960s; they are credited with popularizing and commercializing the sport around the world.
In a career spanning more than six decades, Palmer won 62 PGA Tour titles from 1955 to 1973. He is fifth on the Tour's all-time victory list, trailing only Sam Snead, Tiger Woods, Nicklaus, and Ben Hogan.
