Charles E. Hallstrom (January 22, 1863[1] – May 6, 1949), nicknamed the "Swedish Wonder", was a Swedish Major League Baseball player who pitched one game for the Providence Grays of the National League.[2] The Grays were in need of a pitcher for that day's game versus the Chicago White Stockings, and used Hallstrom, a local Chicago amateur player.[3] Hallstrom is the first of four Major League Baseball players born in Sweden.[4] He was born in Jönköping, Sweden, and died in Chicago at the age of 86.[2] He is interred at the All Saints Cemetery in Des Plaines, Illinois.[2]
