Wilhelm Schickard [SEP] date of death
Wilhelm Schickard
Wilhelm Schickard (22 April 1592 – 24 October 1635) was a German professor of Hebrew and Astronomy who became famous in the second part of the 20th century after Dr. 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.
Dr. Hammer asserted that because these letters had been lost
in Tübingen after taking part in the war. From 1955, Freytag-Löringhoff was Professor of Philosophy at the University of Tübingen. In 1957 he reconstructed the first calculating machine of 1623, which was handed down only in scanty sketches, of the Tübingen astronomy professor Wilhelm Schickard. He also built the data sticks from Schickard. After his retirement in 1977 Freytag studied the structures of the still new PCs.
