1912 Stockholm Games
Track and field star Jim Thorpe dominates the pentathlon and decathlon competitions. He is stripped of his medals when it's learned he was paid to play minor league baseball. The IOC eventually reinstates his Olympic titles about 70 years later.

1936 Berlin Games
During the 1936 Berlin Games, with Adolph Hitler looking on, African-American Jesse Owens wins four gold medals, finishing first in the 100m, 200m, 4x100m relay and the long jump.

1960 Rome Games
Wilma Rudolph -- who was unable to walk until she was seven after suffering from polio, scarlet fever and pneumonia as a child -- becomes the first American woman to win three gold medals at a single Olympics when she wins the 100m, 200m and 4x100m relay.

Eighteen-year-old American boxer Cassius Clay, who would later become known as Muhammad Ali, wins gold in the light heavyweight division to take his first step toward becoming one of the best boxers of all time.

1968 Mexico City Games
U.S. high jumper Dick Fosbury wins gold by using his own technique -- leaping off his outside foot and clearing the bar head first, with his back to the bar. Today all high jumpers use the "Fosbury Flop."

During the medal ceremony for the men's 200m, U.S. sprinters Tommie Smith, who won gold in the event, and bronze medalist John Carlos bow their heads and raise their black-gloved fists. The gesture was meant to demonstrate against racial injustice.

U.S. boxer George Foreman, who had only fought in 18 matches before the Olympics, wins the super heavyweight gold.

1972 Munich Games
U.S. swimmer Mark Spitz wins seven gold medals -- four in individual events and three in relays -- to set a single Olympics record.

Seventeen-year-old Soviet Olga Korbut becomes the first gymnast to ever do a backward somersault on the uneven bars. Korbut, who becomes known as the "Munchkin of Munich," claims silver on the uneven bars and wins golds on the balance beam and floor exercise.

1976 Montreal Games
Fourteen-year-old Romanian gymnast Nadia Comaneci becomes the first person to score a perfect 10.0 in competition. She wins five medals at the Montreal Games, including the all-around gold.

Twenty-year-old American boxer "Sugar" Ray Leonard wins gold in the light welterweight division with a victory over Cuba's Andres Aldama. After the victory, Leonard says he's fought his last fight, but then decided to turn professional a few months later.

1984 Los Angeles Games
Sixteen-year-old West Virginia native Mary Lou Retton becomes the first U.S. gymnast to win the women's all-around crown when she scores a pair of 10s in her final two events to surpass Romania's Ecaterina Szabo for a victory in her first major competition.

American track and field star Carl Lewis wins four gold medals (100m, 200m, 4x100m and long jump) in Los Angeles, equaling the mark set by Jesse Owens at the 1936 Berlin Games.

1988 Seoul Games
American track star Florence Griffith Joyner, known as "Flo Jo," wins gold in the 100m, 200m and 4x100m relay, and claims silver in the 4x400m relay.

After winning two golds at the 1984 Los Angeles Games, diver Greg Louganis defends his titles by winning the men's springboard and platform crowns at the 1988 Seoul Games. However, Louganis' run to back-to-back golds was not without incident. The American hit the back of his head on the board during the preliminary round of the springboard event, causing a gash that needed four sutures to close. Six years later it was learned that Louganis was HIV-positive at the time of the injury.

U.S. swimmer Matt Biondi comes up short in his bid to match Mark Spitz's record of seven gold medals in a single Games, but the American still claims five golds, a silver and a bronze.

U.S. boxer Oscar de la Hoya wins gold, which he dedicates to his mother, who died of cancer two years earlier.

1996 Atlanta Games
American sprinter Michael Johnson becomes the first man to win gold in the 200m and 400m. He wins the 200m in world-record time.

The U.S. women's gymnastics team wins the team gold, thanks in part to Kerri Strug. On the vault, the final rotation, Strug injures her ankle on her first attempt. But despite the injury, the 18-year-old returns to perform her second vault, which appears to clinch the gold for the American squad, although it is later determined that the squad would have won without Strug's heroics. During the medal ceremony, Strug -- whose ankle is wrapped in a soft cast -- is carried out to the medal stand by coach Bela Karolyi.

In the Olympic debut of women's soccer, the U.S. team defeats China in the final to win gold. The American women added another gold at the 2004 Athens Games.

2000 Sydney Games
American Greco-Roman wrestler Rulon Gardner, who grew up on a dairy farm in Wyoming, entered the gold-medal match a heavy underdog. His opponent, Russian Aleksandr Karelin, entered the 2000 Olympics trying to become wrestling's first four-time Olympic champion and remain undefeated in his 13-year international career. But Karelin's resume couldn't defeat Gardner, who won the match in overtime. Gardner followed up his gold with a bronze at the 2004 Athens Games, where he left his shoes on the mat following his match, demonstrating his retirement from the sport.

Australian swimmer Ian Thorpe, known as the "Thorpedo," wins two golds in one night at the 2000 Sydney Games. The 17-year-old won the 400m freestyle in world-record time and then led Australia to a victory over the Americans in the 4x100m freestyle relay.

2004 Athens Games
Michael Phelps falls short in his attempt to match Mark Spitz's mark of seven gold medals in a single Games, but he ties the record for most medals at a single Olympics when he hauls in eight jewels at the Athens Games. The American swimming star won six golds (200m IM, 400m IM, 100m butterfly, 200m butterfly, 4x200m freestyle relay and the 4x100m medley relay) and two bronzes (200m freestyle and 4x100m freestyle relay).

Carly Patterson becomes the second U.S. women's gymnast -- and the first since Mary Lou Retton in 1984 -- to win the all-around gold.

Paul Hamm becomes the first American to win the men's Olympic all-around title. However, his victory is marred by controversy. Bronze medalist, South Korea's Yang Tae-Young, claims there was a scoring error during his parallel bars routine that cost him the title. Officials acknowledged the error, but the results are not overturned. Yang appealed the decision, but the Court of Arbitration for Sport ruled against him in October 2004.
