Happy 52nd birthday today (Wednesday) to an Olympic champion who competed in one Olympic Games and only one event.

Injury limited our birthday athlete to only one Olympics.

This champion won that gold medal on a Wednesday at the age of 21, but not in the hurdles.

You might already know that our birthday person had eleven sisters and only one brother.

Our birthday athlete set an Olympic record in winning the gold medal.

Please name this champion with a birthday on the first Wednesday of June.
