The article sets out to present the history of the departments of Law and Criminal Procedure at the Faculty of Law and Social Sciences of the Stefan Batory University in Vilnius through the prism of the two professors Bronisław Wróblewski and Stefan Glaser. They differed in almost everything (except the place of employment); place of birth, almae matres, and above all the way of pursuing academic passion. Unfortunately, their relationship was significantly affected by their differences in the field of politics too. Wróblewski adamantly believed that criminal law and procedure should be lectured and researched separately, whereas Glaser felt otherwise, perhaps on account of his practical experience. The disputes between both of them concerned inter alia Glaser’s professorship appointment and his election to be dean, the reassignment of the academic tasks of their departments, and last but not least – granting them full professorships.
