Speedy, the answer is a bit convoluted and hard to explain here without opening pandoras box. Suffice to say its somewhat based on jealousy intermixed with a few egos put out by the success of the said gentleman in other activities.
There is much more to the history than that however so I suggest you ask a few old timers who joined late 70's early 80's. In particular see if you can get an answer over a beer with one of the ex AIPA presidents who joined around the same time.
