Crepeau chose these wins on one day as the most impressive athletic achievement since 1850. 1936 Berlin Summer Olympics On December 4, 1935, NAACP Secretary Walter Francis White wrote a letter to Owens but never sent it. He was trying to dissuade Owens from taking part in the 1936 Summer Olympics in Nazi Germany, arguing that an African American should not promote a racist regime after what his race had suffered at the hands of white racists in his own country. In the months prior to the Games, a movement gained momentum in favor of a boycott. Owens was convinced by the NAACP to declare: "If there are minorities in Germany who are being discriminated against, the United States should withdraw from the 1936 Olympics".

On August 5, he won the 200 m sprint with a time of 20.7 seconds, defeating teammate Mack Robinson (the older brother of Jackie Robinson). On
