Grandmaster Kim was born in Seoul, Korea in 1929. He was the son of a full-time merchant and a part-time Sumo wrestler, who had trained in Japan and won the Korean Sumo Championships. The prize, Grandmaster Kim recalls, was the traditional one - a live cow.
An avid sportsman and athlete, the elder Kim wanted his son to master a "manly" sport. In 1945 he enrolled his son in a Western-style boxing club. He was a good student, winning eleven of his fifteen bouts on the Korean amateur circuit (similar to our own Golden Gloves). Two events, however, led to a road he has traveled ever since. In his fifteenth bout he knocked out his opponent and the boy, a friend, lay unconscious for twenty minutes. "I thought" Grandmaster Kim remembers, "that I had killed him."

The other, while studying Sumo in Japan, Grandmaster Kim’s father (Dong Hwan Kim) had witnessed karate training and had been impressed by what he saw. He decided to end his son’s boxing career and in April of 1945 enrolled him in Grandmaster Hwang Kee’s Moo Duk Kwan Tang Soo Do Dojang in Seoul. Grandmaster Kim became a devoted and gifted student of Tang So Do under Grandmaster Hwang Kee’s firm leadership and iron discipline. In 1947 he earned his black belt. Grandmaster Hwang Kee’s training was rigorous and sometimes brutal. He required hard body conditioning through constant repetition. Students punched and kicked the Tal yun bong (makiwara) 100 times a day with each hand and foot, often leaving the board stained with blood. All students had Tal yun bong in their homes, Grandmaster Kim had two. Grandmaster Hwang Kee assigned "homework" and Grandmaster Kim was often up smashing the board well past midnight, sometimes to his neighbor’s chagrin.

In 1952 Grandmaster Kim assisted in the formation of the Korean Tang Soo Do Association in Seoul, Korea. From 1955 to 1959 he was the top Master Instructor of Moo Duk Kwan in Korea. In 1955 he gave an exhibition at the 1st International Goodwill Tang Soo Do Tournament. In 1961, he was appointed Vice President of the Moo Duk Kwan Tang Soo Do Association and in 1962 was elected Vice President of the Korean Soo Bahk Do Association (the parent organization headed by Grandmaster Hwang Kee.) During 1967 and 1968 he was awarded the 8th Dan and appointed president of the Moo Duk Kwan in the United States by Grandmaster Hwang Kee. He brought Moo Duk Kwan Tang Soo Do to the United States and founded the Association In Detroit, Michigan.

Through the years, Grandmaster Kim has toured the world for exhibitions and has trained Master Instructors in Europe, Asia, North and South America and South Africa. Along the way he has found time to train and promote Chuck Norris, Pat Johnson and World Heavyweight Boxing Champion Leon Spinks. Grandmaster Kim also instructed Detroit Mayor Coleman Young’s bodyguards. His selfless contributions to the community have GRAND MASTER JAE JOON KIMresulted in numerous proclamations from mayors around the country. 
Veteran martial artists will recognize that Grandmaster Jae Joon Kim holds one of the highest ranks in Tang Soo Do in the world: in fact his Dan Number is #38, which was awarded by Grandmaster Hwang Kee (the founder of Tang Soo Do.) For over 50 years Grandmaster Kim has been a devoted teacher and inspiration to all who come in contact with him.

Grandmaster Jae Joon Kim has continued to develop the World Moo Duk Kwan Tang Soo Do Federation until his death in January 2007.  The World Moo Duk Kwan Tang Soo Do name has been changed as of August, 2006 to the World Traditional Tang Soo Do Federation due to litigation and compliance with Federal law.  The Federation still stretches its way from California to New York and from Michigan (where the main club started) to Florida, the present world headquarters of the World Traditional Tang Soo Do Federation under the leadership of Grandmaster Saul M. Kim, the son of Grandmaster Jae Joon Kim.  

On April 11, 2015 Grandmaster Saul M. Kim was promoted to the rank of 10th Dan in Oklahoma City, Oklahoma by Grandmaster Cox of San Diego California, Master Ethan Shaw of Wichita Falls, TX, Master Price B. and Master Smith of Oklahoma City, Oklahoma.  Congratulations to Grandmaster!  Tang Soo!
