Wilhelm Schickard Wilhelm Schickard lebte von 1592 bis 1635. Er erfand die erste "Rechenmaschiene" im Dreißigjährigen Krieg (1623). Die Rechenmaschine des Tübingers konnte automatisch addieren, subtrahieren, multiplizieren und dividieren. In einem Brief an Kepler zeichnete er seine Maschine. Die Maschine arbeitete mit Zahnrädern. Zu jeder Dezimalstelle der Additionseinrichtung dieser Rechenmaschine gehörte ein Rad mit zehn Zähnen, das Zählrad. Auf dem Umfang dieser Zählräder (A , A , A , ...) standen die Ziffern 0-9. Jeder Zahn entsprach also einer Ziffer. Auf der Achse jedes Zählrades saß ein weiteres Rad mit nur einem Zahn, das Übertragsrad. Dieses Rad war für den Übertrag auf die nächste Zehnerstufe (Zehnerpotenz) zuständig. Der Übertragszahn (Ü , ...) drehte über ein weiteres Rad (B , B , B ,...) das nächste Zählrad. Das Funktionsprinzip (s. Abb. links): Die Schickardsche Rechenmaschine hätte damals für die astronomischen Berechnungen ein gutes Werkzeug sein können. Man konnte mit ihr addieren, subtrahieren und - im oberen Teil - multiplizieren und dividieren. Leider arbeitete die Maschine niemals zuverlässig. Die Anforderungen an die Genauigkeit überstiegen die damaligen feinmechanischen Möglichkeiten. Ein Nachbau der Rechenmaschine von Wilhelm Schickard made by Blazej Lebek (15.5.2000)

Wilhelm Schickard It is widely believed that the first mechanical calculating device was created by the French mathematician Blaise Pascal in 1642. However, that distinction actually belongs to Wilhelm Schickard, a university professor and Lutheran minister. Schickard was born on April 22nd, 1592 in Herrenberg, Germany. Little is known about his early life. He attended the University of Tübingen, earning a B.A. in 1609 and M.A. in 1611. In 1613, he became a Lutheran minister, serving several towns around Tübingen. He served in this capacity until 1619, when he was appointed Professor of Hebrew at the University of Tübingen. He taught Biblical languages until 1631, when he became Professor of Astronomy. In 1623, Schickard built a mechanical device which could perform mathematical operations. In a letter to Johannes Kepler, written on September 20, 1623, Schickard described his machine as follows: What you have done by calculation I have just tried to do by way of mechanics. I have conceived a machine consisting of eleven complete and six incomplete sprocket wheels; it calculates instantaneously and automatically from given numbers, as it adds, subtracts, multiplies and divides. You would enjoy to see how the machine accumulates and transports spontaneously a ten or a hundred to the left and, vice-versa, how it does the opposite if it is subtracting ... Unfortunately, the only two original copies of Schickard's machine were lost, one in a fire and one after his death from plague in 1635. However, in the 1950s, scholars who were collecting the works of Kepler found, tucked into a book, Schickard's original drawings of his device. This made it possible for Professor Bruno Baron von Freytag Loringhoff of the University of Tübingen to reconstruct Schickard's calculator.

Editorial Introduction The Schickard Calculator is the first known mechanical calculator to add, subtract, multiply and divide. It was invented by the German professor Wilhelm Schickard in 1623, but remained unknown for 300 years. In 1960 it was reconstructed by Baron Bruno von Freytag-Löringhoff. In this study work a simulation of the reconstructed calculator was done using a Java 3D-applet. This makes it possible to perform calculations like Schickard did, watch the calculator from any view point you like and even gain an insight view of case.

Wer war WILHELM SCHICKARD? Biografie Links Biografie Neben den kirchlichen Pflichten beschäftigte er sich intensiv mit alten Sprachen, Astronomie und Mathematik. Im Jahr 1617 begann eine lange währende Freundschaft mit dem zwanzig Jahre älteren, in Linz lehrenden Johannes Kepler. Dieser lobte Schickards sowohl wissenschaftliche als auch praktische Fähigkeiten und nannte ihn einen "Beidhändigen Philosoph". Der württembergische Herzog Friedrich setzte sich 1619 für eine Professur Schickards an der Universität Tübingen für Hebräisch ein. Im Jahr 1631 wurde ihm auch die Professur für Mathematik (Astronomie) übertragen. In dieser Zeit erbrachte er spektakuläre technische und wissenschaftliche Leistungen. Er erdachte Modelle, die er in detaillierten Schriften und Skizzen festhielt. Von ihm stammen Betrachtungen zur hebräischen Grammatik ebenso wie Kartographische Landesaufnahmen zur Vermessung Württembergs. Er konstruierte neben dem Handplanetarium auch die Rechenstäbchen und die berühmte "Rechenuhr". Schickards "Rechenuhr" als Nachbau
