Born in Kraków on the 26th of November, 1869. He studied in Kraków, Berlin, and Vienna. From 1887 he assisted his father in gathering and sorting the materials for Karol Estreicher’s monumental work Bibliografia polska; then he was the proof reader of its successive volumes. After his father’s death, he continued Karol’s opus magnum on his own, publishing ten more volumes of the Bibliografia before 1939. He collaborated with several Warsaw magazines – first and foremost with ‘Ognisko’ – and in 1898 took up the post of the editor of the literary column of the Kraków “Czas” Conservative daily, in which he popularized the ideas of the Young Poland movement. In 1902 he became a professor of the Jagiellonian University; he also repeatedly performed the duties of its dean and rector. From 1912 he was also a member of the Polish Academy of Arts and Sciences, as well as of many other scientific societies. He wrote numerous literary essays dedicated to the output of, among others, Adam Asnyk or Juliusz Słowacki; he was a great admirer of Stanisław Wyspiański’s production, too. His publicist activity was also an important voice in the political debates of the Second Polish Republic, as it represented a standpoint typical of the moderate Conservative environments in, for instance, opposing the political line pursued by Józef Piłsudski’s camp after the May Coup of 1926. Arrested by the Germans together with many other professors of the Jagiellonian University during the Sonderaktion Krakau, he died at the Sachsenhausen concentration camp on the 28th of December, 1939.
