William Adam Meyer was an American baseball player and manager. He holds the dubious distinction of having played with, then managed, two of the worst teams in the history of Major League Baseball.

Henry Roy Hamey was an American front-office executive in Major League Baseball (MLB). A longtime employee of the New York Yankees, he was appointed the club's general manager in November 1960. Inheriting a pennant-winner from his predecessor, George Weiss, he maintained the Yankees' dominant position in MLB by producing three additional American League champions and two World Series champions in three full seasons before retiring in the autumn of 1963. Hamey also spent nine years as the general manager of two National League franchises, the Pittsburgh Pirates and Philadelphia Phillies, during the period between 1947 and 1958.
