Konrad Zuse

Konrad Zuse (1910-1995) was a German engineer and computer scientist. He is credited with building the world's first fully functional program-controlled electromechanical computer, the Z3, in 1941. Zuse also developed the first high-level programming language, Plankalkül, and made significant contributions to the field of computer architecture and design.

Built the first digital freely programmable computer, the Z1. Built the first functional program-controlled computer, the Z3 in 1941. The Z3 already used what later became known as Reverse Polish Notation, and it was proven to be Turing-complete in 1998. Produced the world's first commercial computer, the Z4. Designed the first high-level programming language, Plankalkül.

Konrad Ernst Otto Zuse was a German civil engineer, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse is regarded by some as the inventor and father of the modern computer.

• His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941.
• Zuse was noted for the S2 computing machine, considered the first process control computer.
• In 1941, he founded one of the earliest computer businesses, producing the Z4, which became the world's first commercial computer.
• Possibly his first documented influence on a US company was IBM's option on his patents in 1946.
