Need help ID:ing this olympian

A family member of mine (now passed) has a photo from (I believe) the 1964 Tokyo Olympics, and in this photo there is what seems to be an olympian. No idea what discipline or country. All I know is it’s def not a relative in my family. Anyone have any guesses as to who this could be?
