Jack Johnson
John Thomas "Topeka Jack" Johnson (April 25, 1883 – January 29, 1940) was a Negro leagues second baseman and manager for several years before the founding of the first Negro National League. He was also a professional boxer and trainer, and his nickname may have resulted from the need to distinguish him from the heavyweight champion Jack Johnson. In 1917 Johnson managed "Jack Johnson's Topeka Giants," a team that played at least one game against the All Nations base ball club.

He was also a professional boxer and trainer, and his nickname may have resulted from the need to distinguish him from the heavyweight champion Jack Johnson. Johnson played for the Chicago Union Giants from 1903 to 1905 and again in 1907, his teammates including George Hopkins, Albert Toney, and Joe Green. He founded and managed the Topeka Giants in 1906, taking them on a tour of Nebraska, Iowa, Illinois, Missouri and Kansas.
