J. L. Wilkinson
Baseball executive (1878-1964)

J. Leslie Wilkinson (May 14, 1878 – August 21, 1964) was an American sports executive who founded the All Nations baseball club in 1912, and the Negro league baseball team Kansas City Monarchs in 1920.
Early life
Born in Algona, Iowa, Wilkinson was a promising pitcher until he hurt his throwing wrist. He turned to team ownership and management, parlaying a promotional flair into an association with the game that lasted more than 50 years.
Note: Wilkinson was born as “J Leslie.” He was not given a first name and never adopted one during his lifetime.
Team ownership
In 1909, he developed a women's baseball team—possibly with a few men in drag—to draw up to 2,000 fans to a covered grandstand moved around the Midwest by train. A team band whipped up tunes for crowds, a male catcher wrestled all comers and a brown bulldog served as the mascot. Town teams throughout Iowa and surrounding states faced Wilkinson's gimmick-laden squad.
In 1912, he founded the multi-racial All Nations team in Des Moines, Iowa. The team consisted of whites, blacks, Polynesians, Asians, Native Americans and – at one time – a woman. As did Wilkinson's first venture, it also had a team band and a number of other promotions, but featured a number of athletes of major league calibre, including John Donaldson and José Méndez.
