as the main research tool. As the director of the Institute of Nuclear Physics and of the Institute of Physics of the Jagiellonian University, Niewodniczański was the initiator of the majority of the research carried out in these two institutes. He assembled a group of young scientists who, undaunted by difficult conditions, built with him the necessary equipment and under his inspiration began research works. In 1988, twenty years after his death, the Institute of Nuclear Physics he created was renamed ''The Henryk Niewodniczanski Institute of Nuclear Physics''.
