Irvin Key "Kaiser" Wilhelm (January 26, 1874 – May 22, 1936) was a pitcher and manager in Major League Baseball. Between 1903 and 1914, he moved between the major and minor leagues several times. He played with the Pittsburgh Pirates, Boston Beaneaters, Brooklyn Superbas and Baltimore Terrapins. After 1914, Wilhelm spent time as a player, manager and scout for the minor leagues. In 1921, he became the manager for the Philadelphia Phillies and pitched in four games for the team. Wilhelm held the minor league baseball pitching record for consecutive scoreless innings for 97 years, but was not recognized as the record holder by baseball officials until 2004. Baseball officials declared Wilhelm the record holder a few days before Brad Thompson was thought to have broken the record. Two days after Wilhelm's streak was thought to have been broken, The New York Times reported a historian found three scoreless innings which were previously left off Wilhelm's streak, indicating his record had not actually been broken. Wilhelm is still the current record holder. Early life Wilhelm was born in Wooster, Ohio, to Joseph H. and Celia P. DeMiller Wilhelm. His father had found work as a painter, blacksmith and house decorator. Wilhelm attended Wooster High School; the school did not have a baseball team. He entered professional baseball in 1895 with the Mansfield Kids. Career While pitching for the Birmingham Barons in 1902, Wilhelm threw back-to-back one-hit games. This attracted the attention of Pittsburgh Pirates owner Barney Dreyfuss, who invited Wilhelm to spring training with the Pirates in 1903. Wilhelm appeared in 12 games that year for the Pirates, finishing with a 5–3 win–loss record. He played with the Boston Beaneaters in the next two seasons. In 1904, Wilhelm earned a 14–20 record and gave up a league-high 118 earned runs. The next year he gave up 122 earned runs, second highest in the league, and finished with a 3–23 record. Wilhelm became commonly known as "Kaiser" during his career, a nickname which originated from the early 20th century German emperor Wilhelm II. Playing with the Barons in 1906, Wilhelm pitched the team's first perfect game since its founding in 1884. The 1906 Barons won the team's first title since joining the Southern Association in 1901. His record that year was 22–13. He had similar success the following year, finishing 23–14. Wilhelm returned to the major leagues with the Brooklyn Superbas
