Wyomia Tyus

Wyomia Tyus (pronunciation: why-o-mia; born August 29, 1945) is a retired American track and field sprinter, and the first person to retain the Olympic title in the 100 m (a feat since duplicated by Carl Lewis, Gail Devers, Shelly-Ann Fraser-Pryce and Usain Bolt).
Tyus, from Tennessee State University, participated in the 1964 Summer Olympics at age 19. In the heats of the event, she equaled Wilma Rudolph's world record, propelling her to a favored position for the final, where her main rival was fellow American Edith McGuire. Tyus won the final, beating McGuire by 0.2 seconds. At the same Olympics, she also won a silver medal with the 4 × 100 m relay team.
The following years, Tyus won numerous national championships in the sprint events, and a gold medal in the 200 m at the Pan-American Games. In 1968, she returned to the Olympics to defend her title in the 100 m. In the final, she set a new world record of 11.08 s to become the first person, male or female, to retain the Olympic 100 metres title. Tyus also qualified for the 200 m final, in which she finished sixth. Running the final leg for the relay team, Tyus helped setting a new world record, winning her third gold medal.
Director Bud Greenspan filmed Tyus casually dancing behind her starting blocks before the Olympic final. When interviewed later she said she was doing the "Tighten Up" to stay loose.
Tyus retired from amateur sports after the 1968 Olympics. In 1973 she was invited to compete in the 60-yard dash in the new Professional International Track Association competitions. In her first-year return, she won eight of eighteen events. The following year, she won every event she entered, a total of twenty-two races. Tyus went on to coach at Beverly Hills High School, and was a founding member of the Women's Sports Foundation.
During the Richard Dawson era of Family Feud, Tyus appeared with her family. They won the $5,000 prize. In 1980, Tyus was inducted into the National Track and Field Hall of Fame. At the 1984 Summer Olympics, she was one of eleven athletes who carried in the Olympic Flag during the Opening Ceremony. In 1985, she was inducted into the U.S. Olympic Hall of Fame.
In 1999 her hometown Griffin, Georgia honored her with the unveiling of the Wyomia Tyus Olympic Park.
