Jerzy Pniewski
Jerzy Pniewski (born June 1, 1913 in Płock ; † June 16, 1989 in Warsaw ) was a Polish experimental physicist who dealt with nuclear and high-energy physics. In 1952 with Marian Danysz he discovered hypernuclei and in 1962 isomers hypernuclei.
Pniewski was the son of a high school teacher and studied mathematics and then physics at the University of Warsaw . At first he worked on molecular optics. From 1948 to 1950 he was in Liverpool , where he worked on beta spectroscopy and received his doctorate on it after returning to Warsaw in 1951. In 1952 he started working closely with Danysz - both of them studied cosmic rays with nuclear emulsions. In the same year they discovered hyper nuclei, which they immediately informed Cecil Powell (with whom Danysz had previously been in Bristol) and Werner Heisenberg (via Klaus Gottstein ) by letter . In the meantime, the Powell group had discovered a similar event in old measurement results and the results of the Polish and British physicists were published in Philosophical Magazine in March 1953. Pniewski became a professor at the University of Warsaw and was there from 1953 to 1958 and 1962 to 1975 director of the Institute for Experimental Physics and from 1975 to 1981 dean of the physics faculty.
He had been a corresponding member of the Polish Academy of Sciences since 1964 and a full member since 1971 , an honorary doctorate from the Universities of Lyon and Heidelberg and a member of the Heidelberg Academy of Sciences . In 1969 he received the Marian Smoluchowski Medal .
