On Sunday, May 18, 1947, Jackie Robinson became the first African American to play in a Major League baseball game at Wrigley Field in Chicago. He was the starting first baseman for the Brooklyn Dodgers. My father took me to that game. We had been to three other Chicago Cubs games, so I had a sense of how many people typically attended a game at Wrigley Field. When we entered the park I was amazed at how many people were already there, far more than I had ever seen at a Cubs game.
