Konrad Zuse (1910-1995) was a German computer scientist and inventor and is considered the pioneer of program controlled computers. Zuse developed the first ever program controlled computer, Z1, in 1938, but his greatest accomplishment is considered the Z3, a functional program-controlled Turing-complete computer he completed in 1941. Zuse was also the first to start a commercial computer business.
Konrad Zuse completed the Z1 before World War II, and it was financed by his family. Later, he received funding from the German government. Z1 was a preliminary design of a Turing machine based computer and was later improved to become the Z3 in 1941. Zuse is also the inventor of the first high-level programming language PlanKalKul (Plan Calculus).
Konrad Zuse is also the author of several books and received many awards from the German government.
