Kim Moo-Hong
(alternately rendered as Kim Moo-Woong or Kim Mu-Hyun)
A student from the Choi and Seo's Daehan Hapki Yu Kwon Sool Dojang, was Kim Moo-Hong (Hangul: 김무홍), who later taught at Seo's Joong Ang dojang (Hangul: 중앙 도장) in Daegu. Seo, who promoted Kim to 4th degree, credits Kim with the development of many kicks which are still used in hapkido today. Kim apparentally took the concepts from very basic kicks he had learned from Choi and went to a temple to work on developing them to a much greater degree. Later, in 1961, Kim travelled to Seoul and while staying at Ji Han-Jae's Sung Moo Kwan dojang they finalized the kicking curriculum.
Kim went on to found his Shin Moo Kwan dojang (Hangul: 신무관 도장) in the Jongmyo section of Seoul, also in 1961. Won Kwang-Hwa (Hangul: 원광화) also served as an instructor at this dojang. Kim's notable students were Lee Han-Cheol (Hangul: 이한철), Kim Woo-Tak (Hangul: 김우탁; who founded the Kuk Sool Kwan Hapkido dojang), Huh Il-Woong (Hangul: 허일웅), Lee Joo-Bang (Hangul: 이주방; who founded modern Hwa Rang Do), Na Han-Dong (Hangul: 나한동), Shin Dong-Ki (Hangul: 신동기) and Seo In-Hyuk (Hangul: 서인혁; who founded Kuk Sool Won).
Originally a member of the Korea Kido Association, the organization sent Kim to teach hapkido in the United States in 1969. Upon returning to Korea in 1970, Kim looked to Ji Han-Jae's move to set up his own organization and with the encouragement of his students followed suit and founded the Korean Hapkido Association (Hangook Hapkido Association) in 1971. Later he combined this organization with the groups led by Ji Han-Jae and Myung Jae-Nam to form the Republic of Korea Hapkido Association.
