An Austrian and Swedish nuclear physicist, Lise Meitner discovered nuclear fission,
the process through which a larger atom splits into two(or more) smaller particles.
A discovery by nuclear physicists in a laboratory in Berlin, Germany, in 1938 made the first atomic bomb possible, after Otto Hahn,
Lise Meitner and Fritz Strassman discovered nuclear fission.
In 1938, German chemists Otto Hahn and Fritz Strassmann,
along with Austrian physicist Lise Meitner and Meitner's nephew, Otto Robert Frisch, conducted experiments with
the products of neutron-bombarded uranium, as a means of further investigating Fermi's claims.
