Answer 1

Peter Norman was an Australian track athlete who won the silver medal in 200 metres race in the 1968 Olympics in Mexico city. 

During that race, two American black athletes,  Tommie Smith and John Carlos came first and third respectively. At the medal presentation ceremony, the two American athletes protested against the discrimination faced by blacks in America by displaying the Black Power salute. Norman supported them by wearing a badge of the Olympic Project for Human Rights.
