Bero Magni de Ludosia or Björn Magnusson from Lödöse (died 1465) was a Swedish-born scholar, active at the University of Vienna.
An ink portrait of him preserved in the Bavarian State Library is also the oldest known depiction of a Swedish scholar.
[2] In 1433 he obtained the degree of regent master, entitled to give lectures at the university.
[4] In 1449 he was also made a titular dean at the Diocese of Skara in his native Sweden, a purely formal position but which entailed a higher salary.
[10] His library is the largest medieval book collection known to have been owned by a person connected to Sweden.
