The International Gymnastics Hall of Fame-- Video Blast!
I stumbled across an IGHOF video as I was looking up some other footage, and I discovered a really great little library of gymnastics history! Each inductee has a brief video summary of their life in gymnastics. I've learned some things about gymnasts I was already familiar with and some things about gymnasts I'd only heard of.
Go to the IGHOF YouTube page or start with a video like the one about Agnes Keleti, below, and you'll soon be clicking through a trail of fascinating videos.
