And we have a winner!!

The Manchester computer of 1948 (Built 1946-1948)
It could store 1024 bits on a cathode-ray-tube, enough to demonstrate the
stored-program principle in working electronics, the first in the world to
do so

Built under the direction of Alan Turing and A von Neumann

Not to take away from your point, but why do you include SEAC/SWAC in 
that list? (both National Bureau of Standards computers)
