Interesting find. Wikipedia says Jhoon Rhee born in 1932 started training at age 13 which would be 1945. It also says Nam Tae Hi was his instructor, but that Nam started training in 1946. Nam was a second dan in 1954 and definitely Senior to Jhoon Rhee. I don't see how Nam could have been his instructor if Jhoon Rhee started training sooner unless he started somewhere else. Since I knew Nam's history starting in 1946 and Jhoon Rhee was his Junior circa 1950 was calculated to be Jhoon Rhees start date.
