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. From 1943Zuse, Konrad (1943), "Ansätze einer Theorie des allgemeinen Rechnens unter besonderer Berücksichtigung des Aussagenkalküls und dessen Anwendung auf Relaisschaltungen" [Inception of a universal theory of computation with special consideration of the propositional calculus and its application to relay circuits], unpublished manuscript, Zuse Papers 045/018. to 1945A book on the subject: (full text of the 1945 manuscript) he designed Plankalkül, the first high-level programming language. In 1969, Zuse suggested the concept of a computation-based universe in his book (Calculating Space).
