In December 1938, the German chemists Otto Hahn and Fritz Strassmann sent a manuscript to Naturwissenschaften reporting they had detected the element barium after bombarding uranium with neutrons; simultaneously, they communicated these…

If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively. Josef Mattauch (21 November 1895 – 10 August 1976) was a nuclear physicist and chemist. He was known for the development of the Mattauch-Herzog double-focusing mass spectrometer, for his work on the investigation of isotopic abundances using…
Chemist Otto Hahn and physicist Lise Meitner collaborated on radiochemistry for thirty years in Berlin. In 1918 they discovered the first long-lived isotope of protactinium, and they are also both credited for the 1938 discovery of nuclear… He was knighted in Britain in 1945 for his achievements in physics. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Meitner, and her nephew Frisch, correctly interpreted these results as being nuclear fission. Frisch confirmed this experimentally on 13 January 1939. The man leaned over his creation, carefully assembling the tiny pieces. This was the hardest part, placing a thin silver plated diaphragm over the internal chamber. The diaphragm had to be strong e… In 1934 she was the first to mention the idea later named nuclear fission. With her husband Walter Noddack and Otto Berg she discovered element 75, rhenium.
Lise Meitner (November 7, 1878, Vienna – October 27, 1968, Cambridge) was an Austrian-Swedish physicist. She had a very large role in discovering nuclear fission.

Friedrich Wilhelm "Fritz" Strassmann (German: Straßmann; 22 February 1902 – 22 April 1980) was a German chemist who, with Otto Hahn in early 1939, identified barium in the residue after bombarding uranium with neutrons, results which, when… Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch.

After the war, he was a professor of physical chemistry at the University of Zurich.
