We all hear about the “committee” that approved the poomse but who really designed them? I have talked with committee members and they did not design them, they admit that. History often obscures the workers not the leaders. That sir is a whole other topic and belongs when we get to the end of this chain of thought.
Which committee members did you talk to? The committee who worked on the forms were also the ones who approved them. In 1967-68, the Palgwae and Yudanja poomsae were created by having each committee member create two or three forms on their own. The committee then got together and chose the best ones. In 1972, the committee got back together with three additional members and they worked together to create Koryo 2 and the Taeguek poomsae. There was no separate committee that "approved" of the new poomsae. Again, which committee members did you speak with?
