Karl Schoy

from Wikipedia, the free encyclopedia

Karl Schoy (in a different spelling also: Carl ; * April 7, 1877 in Bittelschieß ; † December 6, 1925 in Frankfurt am Main ) was a German source researcher and author in the field of Arabic astronomy , gnomonics and mathematics .

education

Schoy came from a Catholic family of teachers in the then Hohenzollern Bittelschieß and had two brothers and a sister. He was initially denied higher education because his father had the modest income of a country teacher. He received his first training in the old teacher training college in Meersburg on Lake Constance . He passed the Absolutorium in the Realgymnasium in Karlsruhe in 1901. He obtained his doctorate in 1911 at the Technical University of Munich with a dissertation on the subject of "The historical development of the pole heights in the older peoples" . His doctoral supervisors were Siegmund Günther and Sebastian Finsterwalder .

Life

Schoy was a math teacher in Mülheim an der Ruhr in 1908 and in Essen in 1909 . From 1919 to 1921 he was a private lecturer in the history of mathematics and astronomy at the University of Bonn .

He was a member of the German Mathematicians Association .

Schoy, who was seen as the appointed successor to Heinrich Suter (1848–1922) in the research of Islamic mathematics and astronomy, died on December 6, 1925 in Frankfurt am Main, where he had relocated a few weeks earlier as a university lecturer. The then 49-year-old source researcher died of a stroke.
