Happy 86th birthday today (Saturday) to an Olympic champion who won Olympic gold on a Saturday.

This champion won Olympic gold four days after Thanksgiving.

Our birthday champion shares the same initials as an actor (who recently died) who gained fame on a television variety/comedy show and also made several movies.

No hurdles were involved in either of our birthday athlete's two Olympic gold medals.

Please name this Olympic champion with a birthday on this third Saturday in August.
