Zygmunt and Maria Zaleski 1930
After the war, Zygmunt Lubicz-Zaleski unsuccessfully tried to open a chair of Polish language at the Sorbonne.
However, he managed to organize a language network in many university centres in France, including in Paris, Strasbourg, Nancy, Grenoble or Lyon effectively promoting Polish language and culture. He also lectured at the Institute of Slavonic Studies.
During the twenty years of the interwar period, Zygmunt Zaleski was very active both in the political and literary fields.
He became a delegate of the Ministry of Religious Denominations and Public Education, he dealt with scholarship holders and collected information on cultural and political life. He did not neglect his own development. In 1927 he obtained a doctorate at the Jagiellonian University, in 1929 he was habilitated at the University of Warsaw, where in 1935 he received the title of professor. During holidays spent every year in Poland, he lectured in Warsaw.
Maria Zaleska, after marriage with Zygmunt, gave up her medical career. She dealt with home, family and social activities. She developed her medical interests by participating in numerous lectures on medical celebrities. A lot of her time involved her social work. She was active in FIDAC (the Inter-allied Veterans Federation), where she was a member of the council, and in the female section of that organization, Auxiliaire Féminine (International Federation of veterans), as a board member. She participated in numerous congresses: in Poland, the USA, Portugal, Czechoslovakia and Romania. She was also the vice-chairwoman of the Union for Female Civic Work.
