Logo of a baseball team from the old Negro Leagues, the Newark Eagles. The Eagles played in the Negro National League from 1936 until 1948, when the league disbanded due to Jackie Robinson’s successful integration into the major leagues. They have the distinction of being the first professional team with a female owner, Effa Manley, and under her guidance won the Negro League World Series over the powerhouse Kansas City Monarchs in 1946. Their roster over the years included many players who went on to great major league careers, including Larry Doby, Don Newcombe, Monte Irvin and Ray Dandridge.
