Otto Hahn
Together with Fritz Straßmann and Lise Meitner, Otto Hahn discovered nuclear fission at the end of 1938, ushering in the atomic age.
On December 17, 1938, nuclear fission of uranium was discovered and radiochemically proven by Otto Hahn and his assistant Fritz Straßmann.

Lise Meitner
In exile in Sweden, Lise Meitner and her nephew Otto Frisch published the first physical-theoretical explanation of nuclear fission in February 1939, which Otto Hahn and his assistant Fritz Straßmann had triggered on December 17, 1938 and demonstrated using radiochemical methods.

Ida Noddack
In 1934, Ida Noddack suggested that “when heavy nuclei are bombarded with neutrons, these nuclei break up into several larger fragments.” Since this assumption contradicted common assumptions about the physics of the atomic nucleus at the time, it received no significant attention. The decay of heavy atomic nuclei into lighter elements was considered impossible
The chemist Ida Noddack had already expressed the assumption in 1934 that “when heavy nuclei are bombarded with neutrons, these nuclei break up into several larger fragments.”
