Claude Shannon, Richard Hamming, William Shockley, Ken Thompson, Dennis Ritchie, John Hopcroft & Brian Kernighan. (I am probably forgetting several Nobel prize and Turing award recipients)
One could also argue that both Windows and Unix were necessary phases for general computing given limited hardware resources, and only now is the stateless functional paradise envisioned at MIT in the 1960's actually possible.

Ken Thompson, Dennis Ritchie, and Brian Kernighan, on the other hand, aren't of the same caliber as people like Shannon and Feynman (and the Manhattan project all-stars).
They've had a huge influence on programming, and on IT, but not always for the better from an academic and quality perspective (e.g. Worse is Better), and more as pragmatic hackers and tinkerers than deep thinkers.
To be fair that's also true of almost any three people involved in the Manhattan Project too.
I could argue for Shockley and Hamming, but they were more on an engineering side.
I get the feeling the Manhattan Project is pretty high up with regard to Nobel Prizes / Scientists employed, at least if you count only the research team at the Los Alamos site (the total team was in the 6-digits IIRC because of "Computers", Military staff, and all the physical work of enrichment and metalworking)
I think there's one school in Budapest that might have more laureates among an even smaller student body. Coincidently (or not) there's a rather large overlap of that group an Los Alamo (.
