Bill Klem didn't just call balls and strikes; he invented the modern umpire. When he began his National League career in 1905, umpires were often targets of abuse and ridicule. Klem, with his barrel chest and stern jaw, changed that dynamic through sheer force of personality. He famously declared, 'I never missed one in my life,' cultivating an aura of infallibility. His dramatic, booming strike call and willingness to eject anyone—from star players to managers to entire dugouts—established the umpire as the game's ultimate authority. Over 37 seasons, he worked a record 18 World Series, his presence alone a signal that the biggest games were in steady hands. His legacy is in every umpire who stands firm today, a testament to the standard he set for integrity and control on the diamond.
