John of Gmunden was born c. 1380-1384 in Gmunden am Traunsee (Gmunden), Austria. His origins were long the subject of disagreement. Gmunden am Traunsee, Gmünd in Lower Austria, and Schwäbisch Gmünd were all thought to be possible birthplaces; and Nider, Schindel, Wissbier, and Krafft possible family names. But the research in the records of the Faculty of Arts of the University of Vienna, however, appears to have settled the question. The Vienna matriculation register records the entrance, on October 13, 1400, of an Austrian named “Johannes Sartoris de Gmundin,” that is, of the son of a tailor from Gmunden.
