With a steam-shovel... :-) Well, technically, as you probably know, the mouse came from Engelbart (well, his group; I'm not sure who the individual was); and the display, I'm honestly not sure of. I know the Knight TV system at the AI Lab was a very early bit-mapped display, but I don't know where the idea first appeared. (There were of course influential earlier display systems, such as the one on SAGE, althoug those were of course all stroke-based systems, given the limited memory of the period.) Windows and menus are AFAIK from PARC, but maybe there are antecedents I don't know of. Now I'm not sure how serious _you_ are being! :-) As to the first, there is some truth to it, but like many (all) humans, he was complex... Hard to say what else he would have done, could he have gone on; perhaps not so much (he was getting up there, and people do slow down), but I suspect his early death was a serious loss (in terms of further advances).
