 In his final years in Ireland Łukasiewicz resumed contacts with colleagues abroad, particularly Scholz, with whom he was in constant correspondence. He attended conferences in Britain, France and Belgium, sent papers to Poland before being expelled (with 15 other exiled Poles) from the Polish Academy in Kraków, lectured on mathematical logic at Queen’s University Belfast and on Aristotle’s syllogistic at University College Dublin. His health deteriorated and he had several heart attacks: by 1953 he was no longer able to lecture at the Academy. In 1955 he received an honorary doctorate from Trinity College Dublin. On 13 February 1956 after an operation to remove gallstones he suffered a third major coronary thrombosis and died in hospital. He was buried in Mount Jerome Cemetery in Dublin, “far from dear Lwów and Poland”, as his gravestone reads. Regina deposited most of his scientific papers and correspondence with the RIA. In 1963 the Academy transferred their holdings to the library of the University of Manchester, where they remain, uncatalogued. The choice of Manchester was due to the presence there as a lecturer of Czesław Lejewski, who had studied with Łukasiewicz in Warsaw and twice been examined by the latter for doctoral theses, once in 1939, when war intervened, a second time in London in 1954. Lejewski had seen the second edition of Łukasiewicz’s book on Aristotle’s syllogistic through the press: it appeared posthumously in 1957. In 2022 on the initiative of the Polish government his remains were repatriated and reinterred with military honors in Warsaw's Powązki Cemetery.
