In its earliest years, the National League was not segregated, and a few teams included Black ballplayers, but in 1887 major and minor league owners adopted a so-called “gentlemen’s agreement” that no new contracts would be given to Black players. In 1920, pitcher and manager Rube Foster founded the first of the Negro Leagues, the Negro National League, to organize professional Black baseball, which was played at a very high level. Other professional Negro leagues followed, and for decades the stars of the game played in the Negro Leagues, until the National League and American League began to slowly accept Black players, starting with Jackie Robinson in 1947.  Joining me in this episode is Dr. Leslie Heaphy, Associate Professor of History at Kent State University at Stark, Vice President of the Society for American Baseball Research, founding editor of Black Ball, and author of The Negro Leagues, 1869-1960.Our theme song is Frogs Legs Rag, composed by James Scott and performed by Kevin MacLeod, licensed under Creative Commons.
