Nam Suk Lee (June 28, 1925 – August 29, 2000) born in the city of Yeo Joo, is credited with co-founding the traditional Korean martial art of Chang Moo Kwan in the mid-1940s, and then promoting and expanding it globally. Chang Moo Kwan was one of the five original Kwans which became Tae Kwon Do in the mid 1950s. In his later life Nam Suk Lee was to make the seaside community of San Pedro, California his home, where he reestablished his traditional roots in Chang Moo Kwan. He was 75 and still actively teaching Chang Moo Kwan through the San Pedro YMCA. Nam Suk Lee died in the neighboring Southern California community of Torrance on August 29, 2000, due to a stroke.
