Between The First and The Second World Wars school hygiene was as important as other medical disciplines. In 1922 Stanisłow Kopczyński created an act which concerned sanitary demands for schools being built. The importance of the health and growth of children had been noticed. In 1931 there were 8 school doctors working in Poznań. At that time Poznań was one of four centres engaged in research concerning school hygiene (the other being Warsaw, Kraków and Wilno). A School Sanitary Science Department (E. Piasecki), Anthropological Department (A. Wrzosek, M. Cwirko-Godycki) and Orthopedic Clinic (W. Dega), all at Poznań University were involved. The scientific attainments of these departments was regularly presented at school doctors' meetings. A periodical magazine "Physical Education" (E. Piasecki) was published from 1920 to 1933. In 1939 "School hygiene" (M. Cwirko-Godycki) is was being published quarterly.
