 Marsilius of Inghen was born around 1340 in Nijmegen, a city in the eastern part of the Low Countries  (Netherlands).[1]  In the older literature it is often said that he came from one of the villages in the vicinity of Nijmegen (Inghen), but this view is mistaken. It was based on a confused reading of the Oratio Funebris held in 1396 by Nicholas Prowin at the funeral of Marsilius and published in 1499 at  Mainz.[2]  From 1362 on, Marsilius was master at the Faculty of Arts at the University of Paris, where he was also rector (1367 and 1371), and a student of theology. As a teacher at Paris, Marsilius was much esteemed and his lectures drew large audiences. Among his students were many compatriots, some of whom came from Nijmegen and surrounding villages. In 1378, Marsilius found himself the University’s delegate at the court of Pope Urban VI in Tivoli. In 1379, he instructed one of his colleagues, Hugh of Hervort, to look after his interests in Paris. After 1379, Marsilius’s name is no longer mentioned in the acts of the University of Paris. He probably turned away from Paris because of the imbroglio surrounding the Great Schism of 1378. Meanwhile, he kept in touch with his native city. In 1382 the town council of Nijmegen treated him to a banquet. From 1386 on, Marsilius was master at the University of Heidelberg. There, as in Paris, he held a number of administrative offices. He was one of the founders of the University of Heidelberg, of which he was rector no fewer than nine times, from 1386–1392 and also in 1396. In 1389–1390, as the University’s nuncio together with Conrad of Soltau, he was responsible for transferring the University register to Rome (Boniface IX). At the beginning of the 1390s, Marsilius again took up the study of theology. The masters who taught theology were by then Conrad of Soltau (since 1387) and Matthew of Krakow (since 1394), both from the University of Prague. In 1395/1396 Marsilius finished his lectures on the Sentences and so became the first theologian to obtain the doctorate at Heidelberg. He died a short time later, on August 20, 1396.
