Lise Meitner was a pioneering physicist who studied radioactivity and nuclear physics. She was part of a team that discovered nuclear fission — a term she coined — but she was overlooked in 1945 when her colleague Otto Hahn was awarded the Nobel Prize in Chemistry. She has been called the "mother of the atomic bomb," even though she did not directly have anything to do with its development. Element No. 109, meitnerium, was named in her honor.
