The stepped reckoner or Leibniz calculator was a mechanical calculator invented by the German mathematician Gottfried Wilhelm Leibniz (started in 1673, when he presented a wooden model to the Royal Society of London [2] and completed in 1694). [1]
Leibniz built two Stepped Reckoners, one in 1694 and one in 1706. [5] The Leibniz wheel was used in many calculating machines for 200 years, and into the 1970s with the Curta hand calculator, until the advent of the electronic calculator in the mid-1970s. Leibniz was also the first to promote the idea of an Pinwheel calculator. [6]
Invented by Leibniz in 1673, it was used for three centuries until the advent of the electronic calculator in the mid-1970s. Gottfried Wilhelm Leibniz built a machine called the stepped reckoner based on the design of the stepped drum in 1694. [1]
Gottfried Wilhelm Leibniz (or Leibnitz; [a] 1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic and statistics.
Leroy E. Loemker (December 28, 1900 – November 28, 1985) was an American philosopher and historian of philosophy, best known for his scholarship on the works of Gottfried Wilhelm Leibniz. Over the course of his career, Loemker made significant contributions to the study of early modern philosophy and the intellectual history of the ...
Gottfried Wilhelm Leibniz (1646–1716) was a German philosopher and mathematician. In engineering, the following concepts are attributed to Leibniz: Leibniz wheel, a cylinder used in a class of mechanical calculators; Leibniz calculator, a digital mechanical calculator based on the Leibniz wheel
At the time Martin wrote the book, "mechanical calculating machines were a symbol of high-tech sophistication in the workplace"; reviewer Jonathan Samuel Golan suggests that it was aimed at collectors rather than historians, [5] while the editors of the Bulletin of Science, Technology & Society suggest that instead its purpose was to inform the public.
