1922-1982prof. CZESŁAW EIMER

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.

1924-1977prof. JERZY WEHR

Graduate and – since 1948 – assistant at Warsaw University of Technology, Department of Electronic Engineering. One of the first employees of the Department of Vibration Research Polish Academy of Sciences (1952) in the field of acoustics. At IPPT PAN since the Vibration Research Department was incorporated into the Institute, until his tragic death in the mountains in Hindu Kush. He received the doctoral degree in 1960, habilitation degree in 1967 and professor degree in 1975. Head of the Department of Physical Acoustics (1961-1973), IPPT deputy director for research (1973-1977). Most of his research was devoted to methods of acoustic measurement, relations between parameters of acoustic fields and mechanical properties of solids and fluids, and also the applications of piezoelectric transducers. Author of 2 books, 60 publications and 10 patents. He became a leading authority among the international community of acousticians.
