The Atlas (aka the MU-3 IIRC) was the world's first virtual memory 
machine (paging only, no segmentation) and was designed - like the 
world's first stored-program electronic computer - at Manchester 
University in the UK.

Cambridge built a similar machine called Titan, which was still around 
when I was there in the late '60s, although my first programs, written 
while I was at high school, were for Imperial College's IBM 7090 and the 
numerical analysis course I took at Cambridge - taught by Maurice 
Wilkes, builder of the EDSAC, the world's second computer, and inventor 
of microcode (and a lousy lecturer) - used a PDP-8.
