From Wikipedia:
For about 14 years from around 1920 to 1934, Bill Tilden was generally considered the greatest player of all time. From 1934 through 1967, during the Golden Age of Tennis, when Vines, Perry, Budge, Riggs, Kramer, Gonzales, Segura, Sedgman, Trabert, Hoad, Rosewall, and Laver were the top tier players, Gonzales was considered the best of this period. Since 1968, with the first Grand Slam of the Open Era at the French Open, Champions such as Rod Laver, Jimmy Connors, Björn Borg, John McEnroe, Pete Sampras, Rafael Nadal, and Roger Federer have been considered by their contemporaries to be greater players than Tilden or Gonzales.
