At a breakfast years ago in my parents old home, a breakfast I did not attend, my father (a retired Engineer who once worked with Stanton Friedman at AeroetJet General testing atomic engines) sat with Dutch Schweggman, my *grandfather* (widowed grandmother's second husband and an award-winning math whiz) when Dutch abruptly said, "I think I can prove the (BLANK) theorem."
"Nonsense," my Father said, a bona fide whiz and aeronautical architect in his own right... "that's not possible."
Dutch constructed the picture provided with a straight-edge and compass. At its completion my Dad was reported to have said, "Well, I'll be damned Dutch... I think you did it."
There was some excitement, many "I'll be damned" exhortations. End of story.
My Mother, now deceased, who did attend, saved the paper above (also at http://www.alienview.net/schwegg.jpg) and the bones of the tale.
