While many might think the Harlem Globetrotters hail from New York, their roots actually belong to Chicago’s South Side. The team was founded by Jewish immigrant Abe Saperstein, a man whose incredible foresight led to a shake up in the world of sports and a legacy enshrined in the Basketball Hall of Fame. Matthew and Mark Jacob, brothers and authors of the book “Globetrotter: How Abe Saperstein Shook Up the World of Sports,” spoke to a crowd at the Abraham Lincoln Presidential Library and Museum in January about Saperstein and his instrumental role in basketball and baseball.
