In 1938, Konrad Zuse of Berlin completed the Z1, the first mechanical binary programmable computer, this was however unreliable in operation.

The first was the German work of Konrad Zuse.

Zuse also claimed to have designed the first higher-level programming language, which he named Plankalkül, in 1945 ( published in 1948 ) although it was implemented for the first time in 2000 by a team around Raúl Rojas at the Free University of Berlin — five years after Zuse died.

Konrad Zuse (; 1910 – 1995 ) was a German civil engineer, inventor and computer pioneer.

In 1939, Zuse was called to military service, where he was given the resources to ultimately build the Z2.

However, Turing-completeness was never considered by Zuse ( who had practical applications in mind ) and only demonstrated in 1998 ( see History of computing hardware ).

A request by his co-worker Helmut Schreyer — who had helped Zuse build the Z3 prototype in 1938 — for government funding for an electronic successor to the Z3 was denied as " strategically unimportant ".

On 8 November 1949, Zuse KG was founded.

While working on his Z4 computer, Zuse realised that programming in machine code was too complicated.

Heinz Rutishauser, one of the inventors of ALGOL, wrote: " The very first attempt to devise an algorithmic language was undertaken in 1948 by K. Zuse.

On his religious views, Zuse was an atheist.

Notwithstanding, the idea of programming language existed earlier ; the first high-level programming language to be designed for a computer was Plankalkül, developed for the German Z3 by Konrad Zuse between 1943 and 1945.

Her work never ran because Babbage's machine was never completed to a functioning standard in her time ; the first programmer to successfully run a program on a functioning modern electronically based computer was pioneer computer scientist Konrad Zuse, who achieved this feat in 1941.

The first actual implementation of a Turing-complete machine appeared in 1941: the program-controlled Z3 of Konrad Zuse, but the first machine explicitly designed to be Turing complete and widely appreciated as being universal was the 1946 ENIAC.

A single program was called by Zuse a Rechenplan ( i. e. computation plan ) and already in 1944 Zuse envisioned a device that should read and then automatically translate a mathematical formulation of a program into machine readable punched film stock – a device which he called Planfertigungsgerät ( i. e. plan construction device ).

* The German Z3 ( shown working in May 1941 ) was designed by Konrad Zuse.

The hypothesis that the universe is a digital computer was pioneered by Konrad Zuse in his book Rechnender Raum ( translated into English as Calculating Space ).

The first version of Doxygen borrowed code from an early version of DOC ++ ( developed by Roland Wunderling and Malte Zöckler at Zuse Institute Berlin ); later, the Doxygen code was rewritten by Dimitri van Heesch.

Researchers such as Turing and Konrad Zuse investigated the idea of using the computer's memory to hold the program as well as the data it was working on, but it was mathematician John von Neumann who became widely credited with defining that computer architecture, still used in almost all computers.

Zuse also proposed, but did not complete, carefully rounded floating – point arithmetic that would have included ±∞ and NaNs, anticipating features of IEEE Standard floating – point by four decades.

In two 1936 patent applications, Konrad Zuse also anticipated that machine instructions could be stored in the same storage used for data — the key insight of what became known as the von Neumann architecture, first implemented in the British SSEM of 1948.

In 1967, Zuse also suggested that the universe itself is running on a cellular automaton or similar computational structure ( digital physics ); in 1969, he published the book Rechnender Raum ( translated into English as Calculating Space ).

In 1936 Konrad Zuse also anticipated in two patent applications that machine instructions could be stored in the same storage used for data.

During the festival there are also many lectures, the most well-known speakers are until this day Robert Jungk, Joseph Weizenbaum and Konrad Zuse.

The first programmable computer built by Konrad Zuse used binary notation for numbers.

While Zuse never became a member of the Nazi Party, he is not known to have expressed any doubts or qualms about working for the Nazi war effort.

Konrad Zuse married Gisela Brandes in January 1945-employing a carriage, himself dressed in tailcoat and top hat and with Gisela in a wedding veil, for Zuse attached importance to a " noble ceremony ".

Zuse received several awards for his work:

Plankalkül (, " Plan Calculus ") is a computer language designed for engineering purposes by Konrad Zuse between 1943 and 1945.

The computer could be, for example, a huge cellular automaton ( Zuse 1967 ), or a universal Turing machine, as suggested by Schmidhuber ( 1997 ), who pointed out that there exists a very short program that can compute all possible computable universes in an asymptotically optimal way.

* 1943-Plankalkül ( Konrad Zuse ), designed, but unimplemented for a half-century

Zuse constructed the Z1 in his parents ' apartment ; in fact, he was allowed to use the living room for his construction.

Zuse built the S1 and S2 computing machines, which were special purpose devices which computed aerodynamic corrections to the wings of radio-controlled flying bombs.

Zuse proposed that the universe is being computed by some sort of cellular automaton or other discrete computing machinery, challenging the long-held view that some physical laws are continuous by nature.

In 1948 Zuse published a paper about the Plankalkül in the " Archiv der Mathematik " but still did not attract much feedback-for a long time to come programming a computer would only be thought of as programming with machine code.

A century later, Konrad Zuse built his own machine when electromechanical relay technology was widely available.

Zuse used thin metal sheets to construct his machine.

The original Z1 was destroyed by the Allied air raids in 1943, but in 1986 Zuse decided to rebuild the machine.

A century later, Konrad Zuse built his own machine when electromechanical relay technology was widely available.

In 1937, Schreyer had advised Zuse to use vacuum tubes as switching elements ; Zuse at this time considered it a crazy idea (" Schnapsidee " in his own words ).
