I should have posted a bit more. Here is an interview with GM LEE Yong Bok.
From the 1st American Martial Arts Leaders Taekkyon Instructors Seminar held last year in Cleveland, Ohio, my comments about Taekkyon's modern history.
"Taekkyon is well known as the original form of Taekwondo. It’s existence can be traced back to at least 57 BC. Taekkyon survived several millennia but was almost extinguished under Japanese Colonial Rule during the 1909—1945 period of occupation. However, one Taekkyon practitioner who was still alive and well after the occupation by the name of SONG Duk Ki brought the last remaining remnants of Taekkyon to the edge of modern times. Along came a martial arts historian and researcher who was also a high level Taekwondo Master in search of the roots of Korean Martial Arts. His name is Yong Bok Lee."
"Great Master Yong Bok Lee studied every movement, wrote down every detail and researched all he could from his new found teachers, Grandmaster SONG Duk Ki and his disciple SHIN Han Seung. After painstakingly researching the history of Korea Martial Arts and discovering the principle of Taekkyon, Great Master Lee developed Taekkyon’s first standard curriculum, as traditionally Taekkyon had no standardized format. Then Great Master Lee made a big decision."
"Great Master Lee began the process of adding Taekkyon programs to his existing Taekwondo Dojangs. After time, Taekkyon became very popular, especially among Taekwondo Dan holders. Some Dojang even completely converted over to Taekkyon. Today, Taekkyon is practiced by about 500,000 persons in Korea and is now beginning to spread to other nations."
