This replica of the Stepped Reckoner (or Staffelwalze) machine designed by Gottfried Wilhelm Leibniz (1646-1716) is on display at the Technische Sammlungen Museum (also known as the Deutsches Museum), in Dresden, Germany. Gottfried Wilhelm Leibniz built a machine called the stepped reckoner based on the design of the stepped drum in 1694. It was a digital mechanical calculator which was called the stepped reckoner as instead of gears it was made of fluted drums. Over the decades, scientists have theorized that it was a portable device that allowed its user to input the date and learn the position of the Sun, Moon, and other astronomical phenomena. Joseph-Marie Jacquard Joseph-Marie Jacquard was a weaver. The 'younger machine', the surviving machine, was built from 1690 to 1720.[6]. The Step Reckoner (or Stepped Reckoner) was a digital mechanical calculator invented by German mathematician Gottfried Wilhelm Leibniz around 1672 and completed in 1694. Accordingly, he eventually designed an entirely new machine called the Stepped Reckoner; it used his Leibniz wheels, 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.
