The UNESCO proclaimed the year 1973 as Copernicus Year. Polish immigrants in Denmark, who left the Polish People’s Republic between 1969–1973, with the encouragement of the Editor-in-chief of the newspaper „Chronicle” in Copenhagen, took the initiative to celebrate the great jubilee and arranged a symposium. The main paper, by Professor Leon Koczy (Glasgow), was about Copernicus and the excellent Danish astronomer Tycho Brahe. Participants of the symposium also had the opportunity to listen to five other papers and to take part in a long discussion. The second day of the symposium was dedicated to Polish and international music – a mass was celebrated in memory of Polish scientists and artists who had perished or been killed, followed by a classical music concert performed by immigrant master-musicians. The jubilee celebration in Denmark was under the patronage of Edward Raczyński, Polish ambassador to the UK and one of the Polish political leaders in exile. For the new immigration this was the first great step in their new life, because the symposium was in support of WWII combatant emigration and the President of the Polish Republic in exile.
