Konrad Zuse,

Konrad Zuse built Z1, world's first program-controlled 

computer. Despite certain mechanical engineering problems it 

had all the basic ingredients of modern machines, using the 

binary system and today's standard separation of storage and 

control. Zuse completes Z3, world's first fully 

functional programmable computer in 1941.
