Joe Louis: Joe Louis held the heavyweight title for 140 consecutive months, the longest such streak in boxing history. Many people regarded him as the first black national hero. He also fought two internationally publicized bouts.
Jesse Owens: During the 1936 Berlin Olympics, Adolf Hitler attempted to use the Games as a showcase for his Third Reich and the supposed superiority of the Aryan race.
After winning the Olympics, some of the personal aspects of his discrimination were slowly released. Owens could then eat the all-white restaurants, and travel with the whites as well. But this didn’t happen all at once. In fact, his National achievements were still looked down upon. Whether being the most successful man in the world, Owens was still a black man, and black men were only seen through the eyes of the white as slaves. However, keep in mind, that it was quite rare for black people to be granted this right.
Happy learning!
