Stefan Slopek

Professor Stefan Slopek was born on December 1, 1914 in Skawa near Kraków and died in Wrocław on 22 August 1995. He was a Polish scientist specializing in clinical microbiology and immunology.

Education
After he had completed his secondary education in Tarnopol, he started his medical studies at the Faculty of Medicine in Jan Kazimeirz University in Lvov, having graduated in May 1939. In 1945, upon presentation of the thesis “On modification of Lvov method of serologic examination of syphilis”, he was granted a degree of M.D. at the Faculty of Medicine of the Jagiellonian University in Kraków.

Career
In 1948, he was promoted to the rank of associate professor (docent) on the basis of a dissertation within the subject of microbiology and serology.

In 1950 he was conferred a title of professor at the Department of Microbiology of the Silesian School of Medicine where he carried on his scientific research and in 1957 got a title of full professor.

In 1965 Stefan Slopek was elected a corresponding member of the Polish Academy of Sciences (PAN) and in 1973 as its full member.

Stefan Slopek was an outstanding specialist in the field of clinical microbiology and immunology. Motivated by his great interest in the above mentioned subjects, as early as before the Second World War, he started working for a branch of the State Department of Hygiene in Lvov and at the same time, under a scientific guidance of Prof. N. Gasiorowski, at the Department of Clinical Microbiology of Jan Kazimierz University in Lvov.

During World War II (1941-1945), he worked at the Institute for Research on Thyphus in Lvov with Rudolf Weigel as the head and then at its Kraków branch. At that time he was involved in production of sera, vaccines and diagnostic kits. Immediately after the war, in 1946-1949, 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.

In the years 1949-1954 he was employed at the Silesian School of Medicine as the head of the Faculty and Department of Clinical Microbiology, also fulfilling the duties of the dean of the Medical Department of the Silesian School of Medicine and from 1953 to October 1954 the rector’s duties of the above school.

During the period 1954-1973 Stefan Slopek held the position of the head of the Faculty and Department of Clinical Microbiology of the Wrocław School of Medicine and beginning in September 1954, up to the moment of his retirement in December 1985, the director of the Ludwik Hirszfeld Institute of Immunology and Experimental Therapy of the Polish Academy of Sciences in Wrocław.

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 Institute is known as the centre of research in the field of immunology and experimental therapy in Poland, and owing to its wide cooperation with many foreign laboratories, it renders great service to the exploration of immunological phenomena and immunological differentiation of living organisms.

Phage therapy
The most detailed publications documenting phage therapy have come from Stefan Slopek's group at the Institute of Immunology and Experimental Medicine of the Polish Academy of Sciences in Wroclaw.

Awards and recognitions
As a distinguished immunologist and microbiologist he held a number of responsible positions in the scientific life of Poland. From 1956 to 1987 he was editor-in-chief of the Archivum Immunologiae et Therapiae Experimentalis; in 1962-1990 – the head and president of the Coordination Committee of the interdisciplinary program “Studies and application of immunologic differentiation of organisms” member of the Presidium of its Wrocław branch; president of the Committee of Immunology; a founding member and the president of the Polish Association of Immunologist (and also its honorary member); a member of the International Union of Oncology and a member of numerous scientific societies; a member of the Presidium and the president of the Medical Sciences of the Central Qualifying Board, the vice-president of the Board, and a honorary member of the Polish Microbiological Society.

Publications
Stefan Slopek is the author of over 300 original scientific papers, above 30 reviewed and popularized scientific publications, 7 manuals, 7 monographs among them Immunology, Practical Immunology, Medical Microbiology (published: 1955, 1958, 1965, 1966, 1972), Clinical Microbiology, Dictionary of Immunology (published: 1980, 1983). He is also a coauthor of numerous chapters in books published in Poland and other countries.
