Florence Delorez Griffith Joyner, also known as Flo-Jo, was an American track and field athlete. She is considered the fastest woman of all time based on the fact that the world records she set in 1988 for both the 100 m and 200 m still stand and have yet to be seriously challenged. During the late 1980s she became a popular figure in international track and field because of her record-setting performances and flashy personal style. She died in her sleep as the result of an epileptic seizure in 1998 at the age of 38. She attended California State University, Northridge and University of California, Los Angeles.
