ŁUkasiewicz, Jan(1878–1956)
Jan Łukasiewicz, the Polish philosopher and logician, was born in Lvov. After studying mathematics and philosophy at the University of Lvov he was graduated in 1902 with a PhD in philosophy. Łukasiewicz taught philosophy and logic first at Lvov and from 1915 at the University of Warsaw. In 1918 he interrupted academic work to accept a senior appointment in the Polish ministry of education in Ignacy Paderewski's cabinet. At the end of that year, however, he returned to the university and continued as professor of philosophy until September 1939. During that period he served twice as rector of the university (1922/1923 and 1931/1932). Toward the end of World War II Łukasiewicz left Warsaw. After some time in Münster and then in Brussels, in 1946 he accepted an invitation from the Irish government to go to Dublin as professor of mathematical logic at the Royal Irish Academy, an appointment that he held until his death. Łukasiewicz held honorary degrees from the University of Münster and from Trinity College, Dublin. He was a member of the Polish Academy of Sciences in Kraków, the Society of Arts and Sciences in Lvov, and the Society of Arts and Sciences in Warsaw.
