Julius Pokorny was a scholar of the Celtic languages, particularly Irish, and a supporter of Irish nationalism. He was born in Prague and studied at the University of Vienna, where he also taught from 1913 to 1920. From 1920 to 1935, he held the chair of Celtic philology at Friedrich Wilhelm University in Berlin, before the Nazis discovered that, in spite of being a German nationalist, he was of Jewish descent.
