 From the summer of 1945 Łukasiewicz taught logic at a Polish secondary school set up at a former Polish POW camp in Dössel. In October 1945 they were allowed to travel to Brussels. There Łukasiewicz again taught logic at a provisional Polish Scientific Institute. Being unwilling to return to a Poland under communist control, Łukasiewicz looked for a post elsewhere. In February 1946 he received an offer to go to Ireland. On 4 March 1946 the Łukasiewiczes arrived in Dublin, where they were received by the Foreign Secretary and the Taoiseach Eamon de Valera. In autumn 1946 Łukasiewicz was appointed Professor of Mathematical Logic at the Royal Irish Academy (RIA), where he gave lectures at first once and then twice a week.
