Karolyi coached Nadia Comaneci in the 1976 Olympics, where she was the first person to score perfect tens in Olympic history. Karolyi and writer Nancy Ann Richardson have collaborated on a biography of his life, called "Feel No Fear." The book tells of Karolyi's defection from Romania to the U.S., and how he brought the American gymnasts Mary Lou Retton and Kim Zmeskal into the public eye.
