I always heard founder Choi studied under Takeda, but that is disputed by some. But frankly, most of the history of Hapkido I have learned from posters on MT or checking the internet. It just wasn't an important thing in my studies. My GM would answer my questions, but didn't hold classes on Hapkido history, at least not for 1st Dan nor 2nd Dan. It seemed that as the GM of his own kwan, that wasn't necessary. I got the impression the other GM were the same. He told me that founder Choi came from Japan, having studied there. He said all the old GM knew that. He also told me once who some of the older GM were, but their names didn't mean anything to me then. He also mentioned knowing and studying with some old GM, such as Bong Soo Hong. that name I remembered as I knew him from the movie Billy Jack. When I studied under Jhoon Goo Rhee, it was the same. I thing we just guessed there was some TKD in the sky that trained all TKD instructors or something, all senior instructors came from that. lol And he taught what I would guess was a very traditional TKD. We studied blocks, punches, and kicks. We were taught to constantly work on increasing power and speed. Without it being said, we learned to use gi (focusing energy). I often wonder if I had been able to stay with him and been belted, if I might have been taught more about some of those 'artsy' moves, or been taught some throws or joint locks. Frankly, I agree that grappling moves added to TKD would be an advantage. I think a little more practice in striking and kicking might not help some Hapkido. But as I learned it, probably not that much. In Hapkido, we just learn that as we go and get stronger and faster. Interesting to contemplate though. Week end seminars for BB in Hapkido disgusts me. Or any other MA for that matter. I think I may have run into one myself a few years back. He didn't seem anxious to talk when he found out I was belted and didn't seem to want to answer what style he was belted in.
