Florence Griffith-Joyner, also known affectionately as Flo-Jo, track and field athlete. She is considered the "fastest woman of all time," based on the records she set in the 1988 Olympics for both the 100m and 200m, which still stand and have yet to be seriously challenged. She also became known for her long, ornately painted fingernails. R.I.P. photo by Corbis.
