The Soviet Union returned to the Olympic fold in 1952 after a 40-year absence, a period of time that included a revolution and two world wars. Ironically, the Soviets chose to make their comeback in Finland, a country they had invaded twice during World War II.

This time it was the United States that was surprised by the Soviets, and the USA had to scramble on the last day of competition to hold off the USSR's assault on first place in the overall standings. It was the beginning of an all-consuming 36-year Cold War rivalry.

Despite the Soviets' impressive debut, it was a Communist from another Iron Curtain country who turned in the most memorable individual performance of the Games. Emil Zátopek of Czechoslovakia, the 10,000-meter champion in London, not only repeated at 10,000 meters, but also won at 5,000 and in the marathon–an event he had never run before. He also set Olympic records in each race and topped it off by watching his wife Dana Zátopková win the women's javelin.

Zátopek's unique triple was wildly applauded by the distance-minded Finns, but their greatest outburst came in the opening ceremonies when legendary countryman Paavo Nurmi, now 56, ran into the stadium with the Olympic torch and handed it off to another native legend Hannes Kolehmainen, now 62, who lit the flame to start the Games.

Also, Harrison Dillard of the U.S. won the 110-meter hurdles. In 1948, Dillard, the world's best hurdler, failed to qualify for the hurdles and won the 100-meter dash instead.
