Unlike sports like baseball or football, golf's eras have been primarily defined and dominated by a key one or two players. While baseball is divided into eras based on the differences of the game (Dead and Lively Ball Eras, Integration Era, Free Agency Era, Steroid Era) and football and basketball are mostly defined by mergers, golf's era are most easily divided by the dominant player, and these great players actually cut up the history of golf up quite well. Because 150 years of golf is tough to cut down, today we'll look at everything before Arnold Palmer, right up to and including the Nelson/Hogan/Snead Era.
From the ancient history of the early Open Championship days, to the relative parity of the 1980s and early 1990s, to the modern Tiger Woods era, golf is just begging to be split up and defined. So let's do it.
