William Joseph Klem born William Joseph Klimm (February 22 1874 – September 16 1951) known as the "father of baseball umpires" was a National League umpire in Major League Baseball from 1905 to 1941. Finally he was the last umpire to work the plate exclusively (traditionally the crew chief always worked the plate; today umpire crews rotate base/plate assignments). He was the first to straddle foul lines and stand to the catcher's side for better perspective.
