Paul Guldin
Paul Guldin , originally Habakuk Guldin (born June 12, 1577 in St. Gallen , † November 3, 1643 in Graz ), was a Swiss astronomer and professor of mathematics in Graz and Vienna .
Guldin first learned the goldsmith's art . He was baptized Protestant, converted to Catholicism in 1597 and took the first name Paul. Shortly afterwards he entered the Jesuit order in Munich . There his talent for mathematics was recognized and he was sent to Rome for further training . He then taught in Rome, Vienna and Graz.
His greatest work Centrobaryea appeared in four books in 1635, 1640 and 1641 in Vienna and also contains the zentrobarische rule or barycentric rules today guldinsche rules called, with which one volume and surfaces of solids of revolution can be calculated. However, these rules were already described by Pappos of Alexandria in his mathematical textbook around 300 AD , so this is a rediscovery.
Guldin's private library, comprising around 300 volumes, is now owned by the Graz University Library .
