For 40 years, Olympians Tommie Smith and John Carlos have lived with the consequences of their fateful protest

When the medals were awarded for the men's 200-meter sprint at the 1968 Olympic Games, Life magazine photographer John Dominis was only about 20 feet away from the podium. "I didn't think it was a big news event," Dominis says. "I was expecting a normal ceremony. I hardly noticed what was happening when I was shooting."

Smith and Carlos, winners of the gold and bronze medals, respectively, in the event, had come to the ceremony dressed to protest: wearing black socks and no shoes to symbolize African-American poverty, a black glove to express African-American strength and unity. (Smith also wore a scarf, and Carlos beads, in memory of lynching victims.) As the national anthem played and an international TV audience watched, each man bowed his head and raised a fist. After the two were banished, images of their gesture entered the iconography of athletic protest.
