I met him back around 1965-66 when he was traveling with the Wide World of Sports show. He seemed humble but very good. I saw him jump through the arms of several people to break a board. Impressive. But what really impressed me about him was his speed.
I feel very sad, we lost one of the best taekwondoings of all time, Mr.Cho is sucha legend, we are gpoing to miss him a lot, he was an imprsive but a humble man at once.
His book Korean Karate was pretty good, considering that it was written in the sixties. Not everything was relevant, but his sparring strategies were definitely on the right track, especially if you had little or no sparring instruction. Perhaps that is why it sold so many copies.
