Nathaniel Woodhull "Nat" Hicks was an American professional baseball player. He played as a catcher in Major League Baseball for six seasons, two in the National League. Hicks was one of the first catchers to stand directly behind the batter, which allowed future Hall of Fame pitcher, Candy Cummings to develop the first curveball used in baseball. Hicks was a popular and highly regarded player during his time in baseball, but injuries sustained over the course of his career cut his playing time short.

Robert Vavasour Ferguson was an American infielder, league official, manager and umpire in the early days of baseball, playing both before and after baseball became a professional sport. In addition to playing and managing, he served as president of the National Association of Professional Base Ball Players from 1872 through 1875, the sport's first entirely professional league. His character and unquestioned honesty were highly regarded during a period in baseball history where the game's reputation was badly damaged by gamblers and rowdy behavior by players and fans. However, his bad temper and stubbornness were traits that created trouble for him at times during his career, and caused him to be disliked by many. His nickname, "Death to Flying Things", was derived from his greatness as a defensive player.
