While gazing at DC-11's and L10-11's, I started wondering about engines perched on tails. I've also read about emergency situations where the two engines on the wings failed and the third engine proved to be a life-saver. Does anyone know what person was first responsible for the radical idea of putting an engine above the fuselage? Was it a Boeing engineer? A Lockheed engineer? Do we have his/her name?

I don't have the answer you're looking for, but here's a few corrections:
#1 : It's DC10, or MD11, or the few MD10 that Fedex has.
#2 : The L-1011's #2 engine is located directly behind the fuselage, not above, the S-duct feeds #2 with air.
#3 : I don't recall any situations where #2 was the only surviving engine, however, it did cause UA232 to lose all hydroulics.
If I have to guess, I'd guess Hawker Siddeley with the Trident, or Boeing with the 727.

In 1977, Delta flight 1080, an L10-11, had a bearing break, jamming the left elevator in the up position. Capt. Jack McMahan eventually had to cut power to the two wing engines because he was climbing at too steep an angle. He used the third engine nearly exclusively to get to LAX and land safely.
