I was recently doing a (general) “internet” search for Self-Defense (just to see what came up). One of the items that did, was for “Bruce Tegner's Self-Defense” book. For those that aren't aware of this guy, during the (mid/late)“60's”, his were the only books (readily) available to most people (including myself, when I was a youth during that time period). During his life (1929–1985) he published 80 books on various MA subjects (Hmmmm, yes, a “Jack” of all systems).
Although “The Green Hornet” was on (9/1966-3/1967), Nobody knew (or cared) who “Bruce Lee” was, Tegner's stuff was the only written information available regarding the MA.
Even at my own (young) age, I recognized that what was shown in his books were “simplistic” (if not amateurish). He instructed a number of famous people, and was generally considered to be “famous” himself as well.
Having owned a couple of his books as a youth, I downloaded one just to reminisce. Being “older”, I actually read the first chapter or two (which I hadn't bothered to do when I was younger, LOL). What I found, was a pretty good summation of what “self-defense” should consist of (and an excerpt has been included on this blog's "pages").
He named his system JuKaDo (meaning Ju(do), Ka(rate), and (Aiki)Do. He (obviously, LOL) wasn't fluent with the language, he just "combined" the pieces of the names in order to make a "new" one (sigh). To the "Western" perspective (of the time), doing so, made sense (though making it nearly impossible to write using kanji, LOL) .
