The engineer that put the hump on the front of the 747 was a freep'n genius. 747 without a doubt the the most recognizable aircraft in history.

[Prophet in the wilderness]

Actually, it was the president and C.E.O. of Pan Am airlines Juan Tripp who had the most influence , input, and design of the 747.
Back before the 747 was even built, Juan Tripp thought that the 747 was just a stop gap effort because back in the late 60s most thought that the SST would be the mainstay of airlines, so Juan Tripp told Boeing to add the " 747 Hump " because he saw the future of it being a freighter ( and so it did fulfilled that role ).
But, to Juan Tripps and Boeing's surprise the 747 because the outstanding success, and so the 747 lives on today.
Juan Trip saw that the hump would give it the capability to have a door on the freighters that would hinge up, and the hump would give it the capacity to load big loads on the 747-F.
So ? it was Juan Tripp who had the most design influence of the 747.
Another thing to note is ? in contrast to the wing test of the A-380 failing in it's max load flex text ( Airbus has to reinforce the wings with added metal ) the 747's wing flex test back in 1969 exceeded and surprised, and happily satisfied Boeing that it exceeded the max flex allowed by the F.A.A., the early 747's wing was robust enough that Boeing didn't actually need to put reinforcement into the wings.
