Lise Meitner Biography
Lise Meitner Biography Introduction 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. Source: www.livescience.com About Lisa Meitner Austrian Lisa Meitner was often the lone women in groups of European scientists researching radioactivity. Her influential work in the early 20th century made her a target of the Nazis, so she fled to Sweden in 1938 and it was there that she discovered the power of the fission reaction. Source: jwa.org Nuclear fission The dramatic splitting of the atom— “nuclear fission”—was a discovery which changed our world. Yet few know that it was a woman physicist who discovered the power of nuclear energy just after her dramatic escape from Nazi Germany. Source: jwa.org Meitner’s exclusion from sharing the Nobel Prize The irony of the story of Lise Meitner is that her laboratory partner of thirty years, Otto Hahn, who remained in Berlin throughout the Third Reich, was awarded the Nobel Prize for Chemistry in 1944. Meitner’s exclusion from sharing the Nobel Prize was thus integrally related to her escape from Nazi Germany to Sweden and the consequent social “marginalization” of her important physics research and discoveries. Source: jwa.org Early Life Lise’s parents were assimilated Viennese Jews, who did not practice Judaism. Her father Philipp was a lawyer whose family stemmed from Moravia. In 1873 he married Hedwig Skovran, whose family had emigrated from Russia to Slovakia. They had eight children. Lise was born on November 7, 1878.

At age 23, she was the first woman admitted to the university’s physics lectures and laboratories. Source: jwa.org Early Research Lise Meitner was the second woman to receive a Ph.D. in Physics from the University of Vienna and it was there that she was introduced to Max Planck, father of the quantum theory, who traveled to Vienna after the tragic suicide of Boltzmann. Source: jwa.org Research on radioactive processes Meitner’s pioneering research on radioactive processes led her into an interdisciplinary field in which chemists collaborated with physicists in primitive laboratories, often tracing the “tracks” of decaying particles by eye long into the night. Source: jwa.org Work During Nazi Regime Meitner became an official University Lecturer in 1922, but even in liberalizing Berlin the press jokingly reported the topic of her inaugural speech as “Cosmetic Physics” instead of cosmic physics. Source: jwa.org Death Meitner spent most of her 70s and 80s traveling, encouraging women students to “remember that science can bring both joy and satisfaction to your life.” During her final years she lived close to her nephew Otto Robert Frisch, in Cambridge, England, where she died on October 27, 1968.
