Konrad Ernst Otto Zuse(German:[ˈkɔnʁaːtˈtsuːzə];22 June 1910 – 18 December 1995) was a German civil engineer,pioneering computer scientist,inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlledTuring-completeZ3became 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.[5][6][7][8][9][10]

Zuse was noted for the S2 computing machine, considered the firstprocess controlcomputer. In 1941, he founded one of the earliest computer businesses, producing theZ4,which became the world's first commercial computer.[11]From 1943[12]to 1945[13]he designedPlankalkül,the firsthigh-level programming language.[14]In 1969, Zuse suggested the concept of acomputation-based universein his bookRechnender Raum(Calculating Space).[15][16][17]

Much of his early work was financed by his family and commerce, but after 1939 he was given resources by thegovernment of Nazi Germany.[18]Due toWorld War II,Zuse's work went largely unnoticed in the United Kingdom and United States. Possibly his first documented influence on a US company wasIBM's option on his patents in 1946.[19]

Early life and education

Konrad Zuse was born inBerlinon 22 June 1910.[20]In 1912, his family moved toEast PrussianBraunsberg(now Braniewo inPoland), where his father was a postal clerk. Zuse attended theCollegium Hosianumin Braunsberg, and in 1923, the family moved toHoyerswerda,where he passed hisAbiturin 1928, qualifying him to enter university.[citation needed]

He enrolled at Technische Hochschule Berlin (nowTechnische Universität Berlin) and explored both engineering and architecture, but found them boring. Zuse then pursued civil engineering, graduating in 1935.[20]

Career

After graduation, Zuse worked for theFord Motor Company,using his artistic skills in the design of advertisements.[14]He started work as a design engineer at theHenschelaircraft factory inSchönefeld near Berlin.This required the performance of many routine calculations by hand, leading him to theorize and plan a way of doing them by machine.[21]

Beginning in 1935, he experimented in the construction of computers in his parents' flat onWrangelstraße38, moving with them into their new flat onMethfesselstraße10, the street leading up theKreuzberg,Berlin.[22]: 418 Working in his parents' apartment in 1936, he produced his first attempt, theZ1,afloating-pointbinary mechanical calculator with limited programmability, reading instructions from a perforated 35 mm film.[14]

In 1937, Zuse submitted two patents that anticipated avon Neumann architecture.In 1938, he finished the Z1 which contained some 30,000 metal parts and never worked well due to insufficient mechanical precision. On 30 January 1944, the Z1 and its originalblueprintswere destroyed with his parents' flat and many neighbouring buildings by aBritish air raidinWorld War II.[22]: 426 

Zuse completed his work entirely independently of other leading computer scientists and mathematicians of his day. Between 1936 and 1945, he was in near-total intellectual isolation.[23]

1939–1945

In 1939, Zuse was called tomilitary service,where he was given the resources to ultimately build theZ2.[18]In September 1940 Zuse presented the Z2, covering several rooms in the parental flat, to experts of theDeutsche Versuchsanstalt für Luftfahrt(DVL; German Research Institute for Aviation).[22]: 424 The Z2 was a revised version of the Z1 using telephonerelays.

In 1940, the German government began funding him and his company through theAerodynamische Versuchsanstalt(AVA, Aerodynamic Research Institute, forerunner of theDLR),[24]which used his work for the production ofglide bombs.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. The S2 featured an integratedanalog-to-digital converterunder program control, making it the first process-controlled computer.[25]: 75 

In 1941 Zuse started a company,Zuse Apparatebau(Zuse Apparatus Construction), to manufacture his machines,[26]renting a workshop on the opposite side inMethfesselstraße7 and stretching through the block toBelle-AllianceStraße29 (renamed and renumbered asMehringdamm84 in 1947).[22]: 418, 425 

In 1941, he improved on the basic Z2 machine, and built theZ3.On 12 May 1941 Zuse presented the Z3, built in his workshop, to the public.[22]: 425 [27]The Z3 was abinary22-bitfloating-pointcalculator featuring programmability with loops but without conditional jumps, with memory and a calculation unit based on telephone relays. The telephone relays used in his machines were largely collected from discarded stock. Despite the absence of conditional jumps, the Z3 was aTuring completecomputer. However, Turing-completeness was never considered by Zuse (who was unaware of Turing's work and had practical applications in mind) and only demonstrated in 1998 (seeHistory of computing hardware).

The Z3, the first fully operational electromechanical computer, was partially financed by German government-supported DVL, which wanted their extensive calculations automated. A request by his co-workerHelmut Schreyer—who had helped Zuse build the Z3 prototype in 1938[28]—for government funding for an electronic successor to the Z3 was denied as "strategically unimportant".

In 1937, Schreyer had advised Zuse to usevacuum tubesas switching elements; Zuse at this time considered it a "crazy idea" (Schnapsideein his own words). Zuse's workshop onMethfesselstraße7 (along with the Z3) was destroyed in anAllied Air raid in late 1943and the parental flat with Z1 and Z2 on 30 January the following year, whereas the successorZ4,which Zuse had begun constructing in 1942[25]: 75 in new premises in theIndustriehofonOranienstraße6, remained intact.[22]: 428 

On 3 February 1945, aerial bombing caused devastating destruction in theLuisenstadt,the area aroundOranienstraße,including neighbouring houses.[29]This event effectively brought Zuse's research and development to a complete halt. The partially finished, telephone relay-based Z4 computer was then packed and moved from Berlin on 14 February, arriving inGöttingenapproximately two weeks later.[22]: 428 

These machines contributed to the Henschel WerkeHs 293andHs 294guided missiles developed by the German military between 1941 and 1945, which were the precursors to the moderncruise missile.[25]: 75 [30][31]The circuit design of the S1 was the predecessor of Zuse'sZ11.[25]: 75 Zuse believed that these machines had been captured by occupyingSoviet troopsin 1945.[25]: 75 

While working on his Z4 computer, Zuse realised that programming inmachine codewas too complicated. He started working on a PhD thesis,[32]containing groundbreaking research years ahead of its time,[editorializing]mainly the first high-level programming language,Plankalkül( "Plan Calculus" ) and, as an elaborate example program, the first real computer chess engine.[33]

1945–1995

After the 1945 Luisenstadt bombing, he fled from Berlin to the ruralAllgäu.[34]In the extreme deprivation ofpost-war GermanyZuse was unable to build computers.

Zuse founded one of the earliest computer companies: theZuse-Ingenieurbüro Hopferau.Capital was raised in 1946 throughETH Zurichand an IBM option on Zuse's patents.[35]

In 1947, according to the memoirs of the German computer pioneerHeinz Billingfrom theMax Planck Institute for Physics,there was a meeting betweenAlan Turingand Konrad Zuse inGöttingen.[36]The encounter had the form of acolloquium.Participants wereWomersley,Turing, Porter from England and a few German researchers like Zuse, Walther, and Billing. (For more details see Herbert Bruderer,Konrad Zuse und die Schweiz).

It was not until 1949 that Zuse was able to resume work on the Z4. He would show the computer to the mathematicianEduard Stiefelof the ETH Zurich. The two men settled a deal to lend the Z4 to the ETH.[37]

Zuse's workshop at Neukirchen, 2010

In November 1949, Zuse founded another company, Zuse KG, inHaunetal-Neukirchen;in 1957, the company's head office moved toBad Hersfeld.TheZ4was finished and delivered to the ETH Zurich in July 1950, where it proved very reliable.[14]At that time, it was the only working digital computer in Central Europe,[38]and the second computer in the world to be sold or loaned, beaten only by theBINAC,which never worked properly after it was delivered. Other computers, all numbered with a leading Z, up to Z43,[39]were built by Zuse and his company. Notable are theZ11,which was sold to the optics industry and to universities, and theZ22,the first computer with a memory based on magnetic storage.[40]

Unable to do any hardware development, he continued working onPlankalkül,eventually publishing some brief excerpts of his thesis in 1948 and 1959; the work in its entirety, however, remained unpublished until 1972.[33]The PhD thesis was submitted atUniversity of Augsburg,but it was rejected because Zuse forgot to pay theDM400 university enrollment fee. The rejection did not bother him.[41]

Plankalkülslightly influenced the design ofALGOL 58[42]but was itself implemented only in 1975 in a dissertation by Joachim Hohmann.[43]Heinz Rutishauser,one of the inventors ofALGOL,wrote: "The very first attempt to devise analgorithmiclanguage was undertaken in 1948 by K. Zuse. His notation was quite general, but the proposal never attained the consideration it deserved. "Further implementations followed in 1998 and then in 2000 by a team from theFree University of Berlin.Donald Knuthsuggested athought experiment:What might have happened had the bombing not taken place, and had the PhD thesis accordingly been published as planned?[33]

In 1956, Zuse began to work on a high precision, large formatplotter.It was demonstrated at the 1961Hanover Fair,[44]and became well known also outside of the technical world thanks toFrieder Nake's pioneering computer art work.[45]Other plotters designed by Zuse include the ZUSE Z90 and ZUSE Z9004.[44]

An elementary process in Zuse's Calculating Space: Two digital particles A und B form a new digital particle C.[46]

In 1967, Zuse suggested that theuniverseitself is running on acellular automatonor similar computational structure (digital physics); in 1969, he published the bookRechnender Raum(translated into English asCalculating Space).[15][16][17]

Between 1989 and 1995, Zuse conceptualized and created a purely mechanical, extensible, modular tower automaton he named "helix tower" ("Helixturm"). The structure is based on a gear drive that employs rotary motion (e.g. provided by a crank) to assemble modular components from a storage space, elevating a tube-shaped tower; the process is reversible, and inverting the input direction will deconstruct the tower and store the components. In 2009, theDeutsches Museumrestored Zuse's original 1:30 functional model that can be extended to a height of 2.7 m.[47]Zuse intended the full construction to reach a height of 120 m, and envisioned it for use with wind power generators and radio transmission installations.[3][4][48][2]

Between 1987 and 1989, Zuse recreated the Z1, suffering a heart attack midway through the project. It cost 800,000DM(approximately $500,000) and required four individuals (including Zuse) to assemble it. Funding for thisretrocomputingproject was provided bySiemensand a consortium of five companies.[49]

Personal life

Zuse Memorial inHünfeld,Hesse

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". Their sonHorst,the first of five children, was born in November 1945.

While Zuse never became a member of theNazi Party,he is not known to have expressed any doubts or qualms about working for the Nazi war effort. Much later, he suggested that in modern times, the best scientists and engineers usually have to choose between either doing their work for more or less questionable business and military interests in aFaustian bargain,or not pursuing their line of work at all.[50]

After Zuse retired, he focused on his hobby of painting.[51]He signed his paintings as "Kuno [von und zu] See".

Zuse was anatheist.[52][25]: 12–13 

Zuse died on 18 December 1995 inHünfeld,Hesse (nearFulda) from heart failure.[53]

Awards and honours

Zuse received several awards for his work:

TheZuse Institute Berlinis named in his honour.

TheKonrad Zuse Medalof theGesellschaft für Informatik,and the Konrad Zuse Medal of the Zentralverband des Deutschen Baugewerbes (Central Association of German Construction), are both named after Zuse.

A replica of the Z3, as well as the original Z4, is in theDeutsches Museumin Munich. TheDeutsches TechnikmuseuminBerlinhas an exhibition devoted to Zuse, displaying twelve of his machines, including a replica of theZ1and several of Zuse's paintings.

The 100th anniversary of his birth was celebrated by exhibitions, lectures and workshops.[56][57]

This was particularly true for religious instruction, which now and again seemed even to us pupils to be rather too enlightened. After the 'Abitur' my parents wanted to go to communion with me; it was a terrible disappointment to them when I wouldn't go. They had lived under the illusion that I was a good student when it came to religion, too, which wasn't the case. […] I remember a poem presented by a student, which made a great impression on me. The essence of the poem read, "Basically, you are always alone". I have forgotten the name of the poet, but have often experienced the truth of these words in later life.

After that he concluded a contract with Zuse: the Z4 should be loaned to the ETH after a thorough overhaul and cleaning.
