Matthew “Mack” Robinson was the older brother of baseball great Jackie Robinson. He was also a pretty good track and field athlete, and made the U.S. team that competed in the 1936 Olympics in Berlin. With no coach to help him and running in a worn-out pair of track shoes, Mack broke the world record in the 200-meter race. In fact, he not only broke the world record, he shattered it. And he finished in second place. The man who came in first place was named Jesse Owens.
