The Umpire Plates at the Cosmic Baseball Association

The Professional Umpire
Before the advent of professional baseball, umpires were selected for their knowledge of the rules and gentlemanly characteristics, but not necessarily their objectivity. With the advent of professional baseball the characteristics of strength, authority and confidence were recognized. Bill McLean, an ex-prizefighter is credited with being the first famous umpire in professional baseball. He worked in the National Association in the early 1870s.
