Professor architect Juliusz Żórawski (1898–1967) is presented in this memorial text by one of his close pupils and collaborators. The author describes the air of lectures on architectural design given by Żórawski, and the mood prevailing in the chair headed by Professor at the Faculty of Architecture of the Cracow University of Technology during the first 20 years after the WW II. The case of the city house in Warsaw built in 1937 proves the avant-garde role of Żórawski in the Polish architecture between the two wars. The original text prepared in 1968 is published here for the first time.
