William Joseph Klem, born William Joseph Klimm (February 22, 1874 – September 16, 1951), known as the "Old Arbitrator" and the "father of baseball umpires", was a National League (NL) umpire in Major League Baseball from 1905 to 1941. He worked 18 World Series, which is a major league record. Klem was posthumously inducted into the Baseball Hall of Fame in 1953. Biography Early life Klem was born on February 22, 1874, in the "Dutchtown" area of Rochester, New York. He had changed the spelling of his last name from "Klimm" to "Klem" because he thought it had a better sound. Klem pursued a baseball career as a catcher until he sustained an arm injury. He then worked as a bartender and traveled through the Northeast building bridges. He decided to pursue umpiring after reading a newspaper article about major league umpire Silk O'Loughlin. His umpiring career began in the Connecticut League in 1902. That year, Klem had a run-in with league secretary and team manager Jim O'Rourke after Klem ejected one of the manager's players. O'Rourke threatened that Klem would not umpire another game in the league, but Klem responded, "Maybe so, but I'll umpire this one." He worked in the New York State League the following year. Klem spent the 1904 season in the American Association before joining the NL in 1905. MLB career He worked a record 18 World Series: 1908, 1909, 1911, 1912, 1913, 1914, 1915, 1917, 1918, 1920, 1922, 1924, 1926, 1929, 1931, 1932, 1934 and 1940. No other umpire has worked in more than ten Series. Of the 16 major league teams in existence during his career, all but one—the St. Louis Browns, who would not win a pennant until 1944—appeared in a World Series that he officiated; the only other teams which did not win a championship with Klem on the field were the Brooklyn Dodgers, Philadelphia Phillies (neither of which won a title during Klem's lifetime) and the Detroit Tigers. He was also one of the umpires for the first All-Star Game in 1933, and worked behind the plate for the second half of the game; he later umpired in the 1938 All-Star Game as well. Klem holds the MLB record for most career ejections by an umpire with 251. He called balls and strikes in five no-hitters, an NL record later tied by Harry Wendelstedt. He was also the home plate
