The University of Krakow was first started under Polish king Casimir the Great. Its development was stalled by death of the king, and later the university was re-established by Wladislaw Jagiello grand duke of Lithuania and king of Poland and his wife, Jadwiga, queen of Poland (who donated all of her personal jewelry to the university). It is today called Jagiellonian University. The first chancellor was Peter Wysz and the first professors were Bohemians, Germans and Poles, most of them trained at the University of Prague in Bohemia. The university and the chancellors were partisan to the Council of Basle. Johannes Longinus and Copernicus attended the University of Krakow. Haller established a printing press in Krakow before 1500. By 1520 Greek was introduced by Constanzo Claretti, Wenzel von Hirschberg and Libanus; Hebrew was also taught.
The current Jagiellonian University Krakow exibits among other items the Balthasar Behem Codex.
