:"Johannes von Gmünd is also the name of a 14th century architect, see
Basel Münster "Johannes von Gmunden (Johannes de Gamundia, c. 1380 – 1442) was a German/Austrian astronomer, mathematician and humanist.
He received the degree of a master of arts at
Vienna University in 1406. From 1408, he was a lecturer at Vienna University, lecturing onAristotle 's "Physics" (1408) and "Meteora" (1409, 1411),Peter of Spain (1410) and "algorismus de minutiis" (1412). He fell seriously ill in 1412, and in 1415 and 1416 studied theology, completing a bachelor degree in 1416.He continued lecturing only in 1419, on "algorismus de integris". From 1420, Johannes was permitted to restrict his teaching to the specialized field of the mathematical of astronomy, focussing onEuclid 's "Elements" and the "Sphaera materialis" ofJohn Holywood . With the aid of students (Weidler's 1741 "Historia astronomiae" namesGeorg Pruneck of Ruspach, Georg of Neuenburg, Johannes Schinkel and Johannes Feldner) he compiled voluminous astronomical tables.In 1425, he was elected canon at St. Stephen's Cathedral.Georg von Peuerbach succeeded him at Vienna University in 1450.John's origins are somewhat disputed. He was probably born in
Gmunden ,Upper Austria , but there were also suggestions connecting him withGmünd, Lower Austria , or that he was a Swabian fromSchwäbisch Gmünd who studied inUlm in his youth, based on a document written at Ulm in 1404 by one "Johannes Wissbier de gamundia".Legacy
