Arthur Allyn Jr.

Arthur Allyn Jr. (December 24, 1913 – March 22, 1985) was the co-owner of the Chicago White Sox of the American League with his brother John Allyn from 1961 through 1969. A few years after purchasing the franchise from Bill Veeck, Allyn tried to sell the team to a number of different parties, including Lamar Hunt and Bud Selig (who planned to move the team to Milwaukee, Wisconsin), before selling his share of the White Sox to his co-owner and brother John. Allyn also owned the Chicago Mustangs soccer club that was a charter member of the United Soccer Association in 1967. The Mustangs became part of the newly formed North American Soccer League the following year after merging with the NPSL.
