Description
Wilhelm Schickard (1592–1635) was a German professor of Hebrew and astronomy who became famous in the second part of the 20th century after Franz Hammer, a biographer (along with Max Caspar) of Johannes Kepler, claimed that the drawings of a calculating clock, predating the public release of Pascal's calculator by twenty years, had been discovered in two unknown letters written by Schickard to Johannes Kepler in 1623 and 1624.
Wilhelm Schickard invented his calculating machine in 1623, making it one of the earliest examples of a mechanical calculator. The machine used a system of toothed wheels and rods to perform arithmetic operations automatically, representing a significant advancement in the field of computing at the time.
