St. Louis was once home to two Major League Baseball teams. The St. Louis Browns signed Hank Thompson and Willard Brown in July 1947 making them the third and fourth Black American baseball players to cross the color barrier. This also made the St. Louis Browns the first MLB team to field two Black athletes. Historian and author Ed Wheatley joins St. Louis on the Air to share what this moment means to baseball history and the efforts to keep the history alive.
