Jessie Owens ... kicking Nazi, and most importantly, American racism, butt since 1936. The following from Wikipedia:
In 1936 Owens arrived in Berlin to compete for the United States in the Summer Olympics. Adolf Hitler was using the games to show the world a resurgent Nazi Germany.[citation needed] He and other government officials had high hopes German athletes would dominate the games with victories (the German athletes did indeed achieve a top of the table medal haul). Meanwhile, Nazi propaganda promoted concepts of "Aryan racial superiority" and depicted ethnic Africans as inferior.
Owens surprised many by winning four gold medals: On August 3, 1936 he won the 100m sprint, defeating Ralph Metcalfe; on August 4, the long jump (later crediting friendly and helpful advice from German competitor Luz Long); on August 5, the 200m sprint; and, after he was added to the 4 x 100 m relay team, his fourth on August 9 (a performance not equaled until Carl Lewis won gold medals in the same events at the 1984 Summer Olympics).
The long jump victory is documented, along with many other 1936 events, in Olympia (1938 film) by Leni Riefenstahl.
On the first day, Hitler shook hands only with the German victors and then left the stadium. Olympic committee officials then insisted Hitler greet each and every medalist or none at all. Hitler opted for the latter and skipped all further medal presentations. On reports that Hitler had deliberately avoided acknowledging his victories, and had refused to shake his hand, Owens recounted:“When I passed the Chancellor he arose, waved his hand at me, and I waved back at him. I think the writers showed bad taste in criticizing the man of the hour in Germany.”He also stated:“Hitler didn't snub me—it was FDR who snubbed me. The president didn't even send me a telegram.”Jesse Owens was never invited to the White House nor bestowed any honors by Presidents Franklin D. Roosevelt (FDR) or Harry S. Truman during their terms. In 1955, President Dwight D. Eisenhower acknowledged Owens' accomplishments, naming him an "Ambassador of Sports."
Owens was cheered enthusiastically by 110,000 people in Berlin's Olympic Stadium and later ordinary Germans sought his autograph when they saw him in the streets. Owens was allowed to travel with and stay in the same hotels as whites, an irony at the time given that blacks in the United States were denied equal rights. After a New York ticker-tape parade in his honor, Owens had to ride the freight elevator to attend his own reception at the Waldorf-Astoria.
