Otto Hahn and Lise Meitner
Otto Hahn and Lise Meitner frequently worked together, as can be seen in this 1918 photograph which captures their joint discovery of protactinium. Twenty years later, in 1938, they made the discovery of nuclear fission that won them international fame. A German physicist and chemist, Otto Han (1879-1968) would eventually win the Nobel Prize in 1945. Lise Meitner (1878-1968) was born in Vienna and studied at university there as well as in Berlin. She was a professor of physics at the Berlin University between 1926 and 1933, leaving Germany in 1938 to join the atomic research staff at the Stockholm University. In 1939, Lise Meitner published the first scientific article explaining nuclear fission.
