The oldest faculty of Comenius University – the Faculty of Medicine began operating immediately after the establishing of Comenius University, in 1919. During the first five years of its existence only clinical classes were open. From the 1924/25 academic year all grades of medical studies began to be run and by 1945 most of the courses had been established. Between the years 1939 and 1952 specialists in pharmacy had trained at the faculty, too. It contributed considerably to establishing other faculties of medicine in Slovakia.
