Very quickly some buildings were repaired, and a cadre of professors was built up, many coming from prewar Polish Jan Kazimierz University of Lwów and Stefan Batory University of Wilno. Following postwar border shifts, thousands of former employees of the Lwów Library, the Jan Kazimierz University and the Ossolineum Institute moved to the city. In mid-1948, over 60% of professors at the Wrocław University and Polytechnic were from Kresy, with scholars from prewar Lwów being particularly prominent. Stanisław Kulczyński from the University of Lwów became the first president of the two Polish universities in Wrocław, while Edward Sucharda from the Lwów Polytechnic was the vice-president.
