Petrus Saxonius

from Wikipedia, the free encyclopedia

Petrus Saxonius , also Peter Sachse (born August 16, 1591 in Husum , † September 16, 1625 in Altdorf ) was a German mathematician and astronomer .

Life

Saxonius' parents were Jacob Saxonius (also: Sachse), archdeacon in Husum and Christina geb. Payncks. Saxonius initially studied from 1607 at the University of Leipzig . 1612 then moved to the Altdorf Academy , where he studied with Johann Praetorius . In 1614/15 he visited Michael Mästlin in Tübingen , Christoph Scheiner in Ingolstadt (who presumably inspired him to deal with the subject of sunspots ), Johannes Faulhaber in Ulm and Simon Marius in Ansbach on a study trip . He then returned to Altdorf for a year before embarking on a trip to Leiden , Groningen and his northern German homeland. Praetorius died in 1616, Saxonius went back to Altdorf, where he succeeded Praetorius as professor of mathematics. In 1622 he married Sabine Köchel. After the academy became a university in 1624, two chairs for mathematics were established, Saxonius took over the one for higher mathematics. He died a year later.

Saxonius planned a series of annotated works by mathematicians of the Greek classical period, his earlier death prevented this project. The only publication remained a posthumously published work Maculae solares ex selectis observationibus Petri Saxonii Holsati on 1616 observations of sunspots.

Saxonius continued the collection of astronomical and mathematical manuscripts and prints that Praetorius had begun. The Praetorius Saxonius Library comprised at least 174 volumes. Today they are distributed over different locations, the majority of them have been stored in Schweinfurt since 1687 at the latest . Some of these works can be seen in a permanent exhibition at the Otto Schäfer Museum in Schweinfurt.
