Stanisław Estreicher : zapominany mistrz Bronisława Malinowskiego

In the paper, its author aims to show the degree to which the influence of just a single person, Stefan Estreicher, shaped the earliest knowledge of a student, fresh science graduate and young PhD at the Jagiellonian University, Bronisław Malinowski; the influence of a man that Malinowski deemed to be his master, “his professor”, and, with time, his good friend. We quote Stanisław Estreicher’s most important thoughts, which were often common truths of his times and, to an even higher extent, of the intellectual circles he belonged to. They later appeared in Bronisław Malinowski’s works, often in their edited versions or as specific “reference points” in the issues he addressed.
