(1930–2017), brother of Jerzy Grotowski, renowned physicist, specialising in atomic physics. Having completed his secondary education in Rzeszów, he studied physics between 1948 and 1952 at The Jagiellonian University in Kraków, the institution where he also spent his academic career (becoming a teaching assistant in 1950 and professor in 1976). Between 1996 and 1999 he was director of the Institute of Physics at the Jagiellonian University. He is a member of the Polish Academy of Learning (Polska Akademia Umiejętności – PAU) and head of PAU’s Astrophysics Committee. Kazimierz Grotowski was also a member of the European Physical Society and the American Physical Society. His other interests include mountain climbing and sailing. He and Jerzy maintained close contact throughout Jerzy’s life, engaging in numerous discussions which also concerned contemporary experimental research and science. Although Kazimierz remained sceptical regarding the manner in which Jerzy applied scientific terminology, we can assume that Jerzy’s knowledge of the Niels Bohr Institute or his tendency to seek analogies with and references to the field of physics stemmed from these close relations and contacts with his brother. In 2009, Kazimierz donated Jerzy’s archive, which Jerzy had deposited at his home before leaving for the United States, to the library of the Ossolineum in Wrocław. He died on 23 July 2017.
