Uber den Allgemeinen Plankalkul als Mittel zur Formulierung schematisch-kombinativer Aufgaben" [in] Archiv der Mathematik. Band 1, Heft 6, 1948/49

Karlsruhe: G. Braun GMBH, 1949. First Edition. Near Fine. First edition of Konrad Zuse's first report on his computer programming language Plankalkul, which laid the foundation for modern computing, found on pages [441]-449 of Archiv der Mathematik. Bound in publisher's buff paper wraps lettered in black; all edges speckled red. Near Fine with spine neatly rebacked, light soiling and toning to covers. Several small chips, contents moderately toned, and small circular repair to rear cover at recto. The pioneering computer engineer's review of Plankalkul, a computer language he developed between 1941 and 1946. It was the world's first high-level programming language, which not only dealt with numerical calculations but also combinatorial operations. Zuse is recognized for building the world's first programmable, fully automatic digital computer, Z1, completed in 1938; scarce.
