ジャン・ガレアッツォ・ヴィスコンティ
During the 13th-14th centuries there was an educational institution, "studium", in Parma, but it was closed in 1387 by Gian Galeazzo Visconti, Duke of Milan. The university was opened in 1412 by Niccolò III d'Este, and, although no papal bull was issued, the degrees were granted. In 1420 Filippo Maria Visconti closed it again.
