German civil engineer and computer scientist who built the world's first programmable computer, the Z4, in 1941. His work went unnoticed in the UK and US due to WWII but IBM optioned his patents after the war in 1946.
He intended to study engineering and architecture in college, but he found that the subjects were too boring for him.
In addition to building computer hardware, he came up with the foundations of programming language.
He married Gisela Brandes in 1945; they had five children together.
The computer that he built passed a vital programming test named after Alan Turing.
