Life and career Pniewski was born in 1913 in Płock, Congress Poland. He studied mathematics and physics at the University of Warsaw. He served as Director at the Institute of Experimental Physics of the University of Warsaw between 1953–1958 and 1962–1975 and subsequently as Head of the Department of Physics from 1975 to 1981. In the 1950s, he enabled his physics students to work at CERN, who were officially unable to participate in this project due to political reasons at that time. His contributions to science are in the area of subatomic experimental physics, in particular nuclear physics. In 1952, he co-discovered the hypernucleus with Marian Danysz. The discovery was made with the use of a nuclear emulsion plate exposed to cosmic rays, based on their energetic but delayed decay. This event was inferred to be due to a nuclear fragment containing a Λ baryon. This achievement proved to be fundamental in the development of nuclear and elementary particle physics as for the first time, researchers observed atomic nuclei in which at least one proton or neutron was replaced by a slightly heavier hyperon (containing a strange quark). In 1962, he discovered hypernuclear isomery. In 1964, he received the Order…
