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.
In 1672, Gottfried Leibniz started designing an entirely new machine called the Stepped Reckoner. It used a stepped drum, built by and named after him, the Leibniz wheel, was the first two-motion calculator, the first to use cursors (creating a memory of the first operand) and the first to have a movable carriage. Leibniz built two Stepped ...
Thomas de Colmar Arithmometer (from 1852, significantly different from his 1820 model) uses Leibnitz stepped drum. Considered by many to be the first largely successful mechanical calculator, and the first to be produced in large numbers (thousands) – Gottfried Leibniz built his first stepped reckoner in 1694 and another one in 1706.

Germany: German mathematician, Gottfried Leibniz started designing a machine which multiplied, the 'Stepped Reckoner'. It could multiply numbers of up to 5 and 12 digits to give a 16 digit result. Two machines were built, one in 1694 (it was discovered in an attic in 1879), and one in 1706. [26] 1685 Germany
