Stefan Ślopek (1 December 1914 in Skawa near Kraków – 22 August 1995, Wrocław[1] was a Polish scientist specializing in clinical microbiology and immunology.
After he had completed his secondary education in Tarnopol, he started his medical studies at the Faculty of Medicine in Jan Kazimierz University in Lviv, having graduated in May 1939.
In 1945, upon presentation of the thesis "O modyfikacji lwowskiej metody serologicznego badania kiły" (On Modification of the Lviv Method of Serologic Examination of Syphilis), he was granted a degree of M.D.
During World War II (1941–1945), he worked at the Institute for Research on Thyphus in Lviv with Rudolf Weigel as the head and then at its Kraków branch.
Immediately after the war, from 1946 to 1949, he worked at the Faculty of Bacteriology of the Jagiellonian University and the Laboratory for Production of Sera and Vaccines of the State Department of Hygiene in Kraków.
As a result of his long term efforts the new premises at 12 Czerska street were built and since 1975 have been the location of the Ludwik Hirszfeld Institute of Immunology and Experimental Therapy.
The most detailed publications documenting phage therapy have come from Stefan Ślopek's group at the Institute of Immunology and Experimental Medicine of the Polish Academy of Sciences in Wroclaw.
