Benjamin Ursinus (mathematician)
Benjamin Ursinus (actually Benjamin Behr ; Latinized Ursinus ), (born July 15, 1587 in Sprottau , Principality of Glogau ; † September 27, 1633 in Frankfurt an der Oder ) was a German mathematician and astronomer.
Life
Benjamin Ursinus was court master (private teacher) in Prague and then grammar school teacher at the grammar school of the Unity of the Bohemian Brothers in Sobieslau and Beuthen (1614). He was in contact with Johannes Kepler , whom he supported in calculating the Rudolfinian tables and with whom he was later friends. From 1615 he was at the Joachimsthal Gymnasium in Berlin and from 1630 mathematics professor at the University in Frankfurt an der Oder .
In 1618 he published log tables by John Napier , printed in Cölln on the Spree , with numbers shortened by two digits and based on Napier's 1614 edition. In 1624 he published an improved, self-calculated table with one digit higher accuracy. In 1623 he published a German edition of Napier's Rhabdologia, which described his calculators, which influenced Ursinus Wilhelm Schickard's contemporary in his calculating machine (possibly via Ursinus).
