Ireneusz Roszkowski born on 24 March 1909, in Łapy in the Białystok region, into a family with patriotic noble traditions, with the coat of arms Ogończyk, eldest son of Franciszek and Natalia (née Wnorowska).

During his studies he attended lectures with such as professors: Mściwój Semerau-Siemianowski, Witold Orłowski, Adam Czyżewicz, Tadeusz Butkiewicz, Henryk Gromadzki, Dr. Roman Welman.

After completing military exercises he was promoted to the rank of second lieutenant, sanitary division, allocated to the officer resources of the district hospital in Warsaw.In 1936 – 1937 he worked at the Saint Sophie Gynecological – Obstetrics unit.

On 15 October 1939, thanks to the help of his uncle Wacław Roszkowski and friend, Jerzy Niżałowski, he managed to escape from the POW camp and returned to Warsaw.

For a young doctor these were years of hard work, with continuous extra operations in addition to the scheduled ones, carried out in secret, with great risk to life as extensive gunshot wound operations (each gunshot wound had to be reported to the German authorities).

Ireneusz Roszkowski was part of the team of surgeons operating on wounded soldiers from the Resistance, amongst whom, were those injured in the assassination attempt on the head of the Gestapo, Kutschera.

From 1944 to 1945 he was one of the initiators and organizers of the teaching of medical students on Boremlow, which at the end of the war evolved into the structure of the Faculty of Medicine at the University of Warsaw.

His professorial thesis entitled "The thyroid and ovulation mechanism", was presented and defended on 8 July 1947 before the Council of the Faculty of Medicine at the Medical Academy in Gdansk ("Polish Gynaecology magazine" 1948 No.

From 1951 to 1955, he was the Head of the Obstetrics and Gynaecology Clinic of the University of Medical Sciences in Poznan on Polna Street.

Since then, analysis of the causes of death of fetuses and newborns is carried out by a team including obstetricians, neonatologists, pathologists, bacteriologists, immunologists, neurologists, biochemists and other disciplines, depending on the specific clinical situation.

In 1962 at the Conference of Polish Gynecologists in Gdansk he presented a paper on the programme entitled "Pathophysiology of fetal hypoxia".

In 1974 at the Polish Gynaecology Society (PTG) Conference in Katowice he presented a paper titled "Pregnancy of high risk" – based on analysis of his own clinical / biochemical material.

Throughout his working life he applied the basic principle of trying to exclude as far as possible, intra and post-operative complications.

His surgical capabilities and in-depth knowledge of anatomy allowed him to carry out some of the most complicated gynecological and oncological operations.

The essential result was the upgrading of the professional skills of midwives and the possibility of post-graduate education at universities not only in the field of medicine, but also psychological and pedagogical.

All his procedures were dominated by concern for the welfare of the patient and their problems and he passed on these characteristics to many students and colleagues.

He trained a large group of medical specialists, scientists and academics both in Poznan and Warsaw.

Professor Roszkowski's organizational and scientific activities far outgrew the boundaries of just midwifery and gynaecology.

Based on his scientific and teaching experiences and clinical research, he produced dozens of films, of which 17 were presented at conferences in Poland and abroad.

In addition to taking part in many conventions and national symposia Roszkowski attended foreign congresses in Geneva (1954), Basel (1954), Belgrade (1959), Zagreb (1962), Dubrovnik (1963), Ljubljana (1969), Prague (1961, 1963, 1965, 1967), Moscow (1963, 1973), Berlin (1965, 1967), Bratislava (1970), Rome (1972), Lausanne (1972), Athens (1973), Uppsala (1976), Dresden (1978), Vienna (1961, 1972, 1978), Leipzig (1965) and Paris (1965, 1967).

He ensured the publication was of a very high standard and made sure that all the published articles related to the creation, not destruction of life.

Out of choice, he served in many capacities at medical universities and scientific societies; he served as Dean (1958–1960) and Vice Dean (1960–1962) of the Medical Academy in Warsaw; took an active role on the Boards of numerous institutions and the Ministry of Health; was a longtime member of the Government Commission on Population policy; a long time Chairman of Fetus Pathophysiology Commission PAN; a member of the Science Committee on demographics; Chairman of the Medical Demography section of PAN; Chairman of the committee on natural birth defects and fetal damage PAN; a member of the Scientific Council of the Institute of Mother and Child; a scientific expert for the Central Commission for Science for the President of the Council Of Ministers.

On the reverse was a notable inscription: "This Medal is a symbol of gratitude to those who create timeless values, for those who have found a place in history and in people's hearts and minds".

Throughout his working life he benefited from the resources of the main medical library in Warsaw by familiarizing himself with the newest developments in medicine.

In 1949, Roszkowski married Halina Obrocka (19 February 1922 – 2 September 1999), a medical student originally from Wilno and the daughter of a lawyer.

A plaque commemorating Roszkowski was erected and solemnly dedicated at the Church of the Holy Redeemer in Warsaw on 17 November 1999.
