When in 1951 by the decision of the communist state the activities of Polska Akademia Umiejętności (PAU) has been suspended, Polish émigré circles were presented with a challenge to maintain the independence of the Polish Library in Paris. It took years of legal battle in French courts and even at the French parliament to resolve the issue. Final verdict of the Tribunal of Appeals has severed any links between the Library and Polska Akademia Nauk - the communist backed successor of the PAU. In 1975 the building and the library has been passed to 'Towarzystwo Historyczno-Literackie' which was obliged to maintain the building. This has brought considerable burdens on the Polish Diaspora and a special appeal for funds has been announced by Andrzej Poniatowski. It was met with a positive response and among many, colonel Roman Umiastowski has given 10.000 dollars to renovate the building. This article presents an exchange of letters between Jan Nowak-Jezioranski, who was a coordinator of the appeal for funds, and colonel Umiastowski.
