Ken Butler, a very pleasant and unassuming man. After Vincents he designed and built the "Bat Bike", a feet forward device. He's a very talented engineer. His byline in "M.P.H." Verbum satis sapienti" I believe the Latin is incorrect, but I think he meant by it "a word is sufficient to the wise." By the way, I'm no Latin scholar, or much of anything, really. So I'll invite correction for dear Ken and myself- as usual.
