During the season, he was sold to the Duluth Dukes of the Northern League for the money Sioux Falls needed to finance their next road trip.
[5] He objected to the trade because Sioux Falls would cover players' living expenses on the road trip, while Duluth was going to be starting a homestand, meaning Horning would need to find a place to rent.
After spending a few weeks with Duluth, Horning enlisted in the United States Army Air Corps, leaving during the 1942 season.
[1] In August 1951, Representative Emanuel Celler announced that he was calling Horning as a witness before the United States House Judiciary Committee to examine the anti-trust exemption granted to Major League Baseball (MLB).
Celler's final report suggested that the U.S. Congress should take no action, allowing for the matter to be settled in the federal judiciary of the United States.
The Supreme Court of the United States upheld MLB's anti-trust exemption and the reserve clause in Toolson v. New York Yankees, Inc. in 1953.
[18] Horning began to pursue a Doctor of Philosophy in Russian history, international law, and European and American diplomacy.
[19] Horning completed his Doctor of Philosophy degree in October 1958 and became a professor at Wisconsin State College at Eau Claire that year.
Speakers have included Chuck Hagel, George McGovern, Eric Schlosser, Margaret MacMillan, and Scott Simon.
