In 1946, he became associate professor, and head of the Department of Strength of Materials at the AGH University of Science and Technology in Cracow. He organized research in the field of prestressed structures and applied mechanics at two universities – the AGH and the newly-established Cracow University of Technology. In 1952, he started his cooperation with the Warsaw University of Technology and the then-establishing Polish Academy of Sciences and created the first Department of Theory of Elasticity and Plasticity and the Department of the Mechanics of Continuous Media, thus creating solid foundations for the IPPT, which he directed until 1970.

In 1954, he became a corresponding member, and in 1956, a member of the Polish Academy of Sciences. Director of IPPT (1963-1970), Secretary to the 4th Department of the Polish Academy of Sciences (1957-1960), member of the PAN Presidium, co-organizer and rector of the International Centre for the Mechanical Sciences in Udine (CISM) (1970-1980). Creator of the world-famous Polish school of theory of elasticity. His scientific research included: theory of elasticity; theory of prestressed structures; rheology.

Author of 290 scientific papers, 10 monographs, editor of 6. Co-founder and member of the board of the RILEM and IASS, IUTAM and IABSE. Co-founder of the Archiwum Mechaniki Stosowanej (Archives of Applied Mechanics) and Rozprawy Inżynierskie (Engineering Theses), 1949. Member of editorial committees of many magazines, organizer of international meetings. He initiated the Polish Conference of Solid Mechanics. Great international authority, propagator of the achievements of Polish mechanics abroad. Supervisor of 16 doctoral students. Honorary doctor (doctor honoris causa) of 9 domestic and foreign universities. Member of 17 foreign academies of sciences. Winner of many state and international awards, a two-time winner of the Polish State Award.

Prof. Eimer graduated from the AGH University of Science and Technology (1949); he received the doctorate degree in 1951; he was made associate professor in 1962 and professor in 1969. He worked at IPPT PAN since its establishment in 1952. He headed the Laboratory of Theory of Elastic Structures (1955-1959), Rheology of Structures (1969-1981), and IPPT Doctoral Study (1968-1978). An outstanding civil engineer. Co-author of pioneer papers on reinforced structures and the rheology of structures (theory, bridge designs, Polish Standard PN-B, patent for the continuous production of prestressed concrete etc.) A well-known researcher into multiphase media; he proposed a rheological model of micro-cracked concrete, later known as Eimer’s micro-cracked concrete. He managed a project aiming at setting up the calculations of containment building of a nuclear reactor in Żarnowiec. He was one of those scientists who could combine abstract thinking with practical use of the technical knowledge. He co-authored two monographs and authored ninety-two publications in prestigious Polish and foreign journals.

Graduate of the Gdansk University of Technology, Faculty of Electrical Engineering (1942). From 1953 to 1962 at the Department of Analogy IPPT, which he headed. Again at IPPT since 1974- head of the Department of Aeroacoustics. He received the doctoral degree (PhD) in 1959, habilitation degree (DSc) in 1965, 1972 – associate professor degree, 1980 – professor degree. Author of over 100 scientific papers in the fields related to aerodynamic sound generation, industrial noise reduction, interior acoustics, theory of acoustic screens, sound source identification and acoustic energy transmission paths. Organizer of numerous international conferences, including 2nd FASE Congress and INTER-NOISE'79. Long-term Secretary of Research of the Polish Academy of Sciences Committee on Acoustics, co-founder of PTA (Polish Acoustical Association). Creator and editor-in-chief (since 1966) of the Archiwum Akustyki (renamed to the ‘Archives of Acoustics’ in 1974).

Radio and electronics engineer. One of the first graduates of the Warsaw University of Technology (WUT) in 1919 and the Military Academy for communications officers in Paris (1922). As such, he was a lecturer on radio engineering in military schools.

In 1928 he received a doctorate degree for his thesis on radio wave stability compensation method (Metoda kompensacyjna kontroli stałości fali) and was appointed Chair of Radio Engineering at the WUT Faculty of Electrical Engineering. In 1929 he was appointed associate professor and subsequently, professor in 1935.

In 1928 he initiated the establishment of the first radio engineering institute in the country (later Institute of Telecommunications), which he directed since 1934. During occupation years, he was the underground lecturer at University. Simultaneously to his educational career, he was a soldier of the Polish Home Army, in which he managed to decipher missile navigating systems of V-2 rockets. In 1945 he founded the WUT Faculty of Electrical Engineering (later Faculty of Communications), where he chaired the Radiolocation Institute until retirement in 1968. He organized the first Polish Academy of Sciences (PAN) research units: the Electronics Unit and The Institute of Fundamental Technological Research in Science (IPPT), to which the unit was later incorporated. In 1961-1963 he was appointed Director of IPPT PAN.

Janusz Groszkowiski was an outstanding expert in high vacuum measurement. He gained international recognition for his work on ionizing heads for low-pressure measurement. Author of 16 patents and 361 scientific papers, also books (Techinika wysokiej próżni, 1972). Supervisor of 33 dissertations.

Since 1936, he was a member of Akademia Nauk Technicznych (Academy of Technical Sciences), since 1949 – Towarzystwo Naukowe Warszawskie (Warsaw Scientific Society), since 1952 he was a member of the PAN, since 1957 – its vice-president, and then in 1962-1971 its president. He resigned from being a member of the Sejm (lower house of the Polish Parliament) of the PRL - People’s Republic of Poland, and vice-president of Rada Państwa (the State Council), as an act of protest against progressing political repression in 1976. Member of 6 foreign academies of sciences (Czechoslovakia, Hungary, the Soviet Union, Romani, Bulgaria and Cuba) and honorary member of many associations. Laureate of the First Class State Award (1951, 1955, 1968, 1979). He was conferred the degree of honorary doctor (doctor honoris causa), at: Warsaw, Gdansk, and Łódź Universities of Technology. Holder of state awards: the Gold Cross of the Virtuti Militari War Order, Commander's Cross of the Order of Polonia Restituta (twice), Officer's Cross of the Order of Polonia Restituta.

The Military Communication Institute credited professor Groszkowski’s scientific achievements, giving the Institute his name.
