Ok not to be disagreeable, but you can be right. Many people will trace much of what became TKD to the CDK, there is little doubt about that.
However when I use the term "Original TKD" I am referring to Gen Choi's TKD that they started to develop in the ROK Army. By that I mean it was the ORIGINAL or 1st system of Korean Martial Art to apply the name TKD to it, continuously from 1954/5 to present day.
So it can really boil down to both semantics & definitions of how the term is applied or used.
It may be semantics George, but even under your definition, Oh Do Kwan doesn't apply because they did not use the name Taekwon-Do continuously. The Oh Do Kwan, like all the other Kwan that was part of the Korea Taesoodo Association, used the name Taesoodo to describe their art from 1961-1965.
In fact, GM NAM Tae Hi and GM KO Jae Chun were members of the group that created the Korea Taesoodo Association.
Modern History: "Since then, the representatives from each Kwan finally decided to gather to have a Unification Conference at the Korean National Sports Auditorium on September 14, 1961. Participants of this Conference were YOON Kwe Byung (Jidokwan representative), UHM Woon Kyu (Chung Do Kwan representative), LEE Nam Suk (Chang Moo Kwan representative), HWANG Kee (Moo Duk Kwan representative), RO Byung Jick (Song Moo Kwan representative), NAM Tae Hi (Oh Do Kwan representative), PARK Chull Hee (Kang Duk Won representative ), and LEE Kyo Yun (Han Moo Kwan representative). Also in attendance were LEE Chong Woo (Jidokwan/Han Kuk Che Yuk Kwan), LEE Byung Ro (Jidokwan/Han Kuk Che Yuk Kwan), KO Jae Chun (Oh Do Kwan) and LEE Young Sup (Song Moo Kwan)."
On September 20, 1961, the name Taesoodo was voted and agreed upon. GM NAM Tae Hi, as Oh Do Kwan Jang, participated:
Modern History: "The next part was the most sensitive topic of the meeting, which was the naming of the art. NAM Tae Hi said "I strongly suggest that the name has to be Taekwondo because the name Taekwondo was passed when the meeting had been held in 1959." UHM Woon Kyu agreed with NAM Tae Hi but YOON Kwe Byung said: "We agreed on the name Taekwondo unanimously because the Ministry of Education decided on the name
Taekwondo, so it was not agreed unanimously." YOON also said, "And so we suggest Kong Soo Do be the name." YOON Kwe Byung was serious and his idea was that the name ong Soo Do (Karate Do) was the name recognized internationally, which was his strong argument. RO Byung Jick and LEE Nam Suk agreed with this. Because YOON Kwe Byung realized that the situation was going to messed up, he suggested Tae Soo Do, which came from Tae (Taekwondo) and Soo (Kong Soo Do). After the voting, the result was Taesoodo, which had 4 votes for and 2 votes abstention."
The first President of the Korea Taesoodo Association, General CHOI Myung Shin, was at the time Chairman of the ROK Joint Chiefs of Staff. If you were President of the Taesoodo Association, and Chairman of the Joint Chiefs, would you continue to have the art called Taekwondo in the ROK military, or would you instead choose to call the art Taesoodo, which is what the organization that you are president of calls it?
In November 1962, the KTA had its first promotion test. Participating from the Oh Do Kwan were CHOI Myung Shin, HYUN Jong Myung, KO Jae Chun and BAEK Joon Ki, among others.
Modern History: "The first Promotion Test was held at the Kuk Min Hwe Eui Dang on November 11, 1962. The Korea Taesoodo Association supported the event, along with the Korean Amateur Sports Association (KASA), the Daehan Jaekeon Kukmin Un Dong Bonbu (political party) and the Dae Han Ilbo Sa (Korea Newspaper Company). There were 25 judges and they included: CHOI Myung Shin, LEE Nam Suk, LEE Chong Woo, UHM Woon Kyu, PARK Chull Hee, LEE Young Sup, HYUN Jong Myung, HONG Jong Pyo, KIM Soon Bae, KIM Soo Jin, LEE Byung Ro, KO Jae Chun, LEE Kyo Yun, BAEK Joon Ki, among others."
At this test, the Chang Hon tul were used to test applicants from the Oh Do Kwan.
Modern History: "CHOI Hong Hee's Chang Hon Ryu forms Ge Baek and Choong Moo used at the Oh Do Kwan was included in this promotion test."
This means that Oh Do Kwan members were given Korea Taesoodo Association dan certificates. Over and above all of this is the universal understanding that the Oh Do Kwan was a close annex kwan of the Chung Do Kwan, and the two pretty much did things in unison, including but not limited to use of the name Taesoodo. This goes farther, because the GM HYUN Jong Myung (not Myun) was a member of the KTA committee that created the Palgwae, Taeguek and Yudanja poomsae. By including an Oh Do Kwan representative, then all factions were included in the creation of the new forms, which served to eliminate any objections to use of these forms.
Therefore, Oh Do Kwan did NOT as you erroneously state, use the name Taekwondo continuously. Looks like you are going to have to change the name of your dojang George.
