Elise Meitner

Lise Meitner stands among the towering scientific minds of the twentieth century, yet for decades her name was overshadowed by the achievements she made possible. An Austrian-born physicist who spent the most productive years of her career in Berlin, Meitner co-discovered the process of nuclear fission—the splitting of the atom that would unlock both energy production and the atomic bomb. Denied the Nobel Prize that her collaborator Otto Hahn received alone in 1944, Meitner’s story is one of brilliance, exile, and belated recognition, and it remains a touchstone for discussions about women in science and the ethics of scientific discovery.

Early Life, Upbringing & Education

Elise “Lise” Meitner was born on 7 November 1878 in Vienna, then the capital of the Austro-Hungarian Empire, into a secular Jewish family of eight children. Her father, Philipp Meitner, was one of the first Jewish lawyers permitted to practise in Austria, and the household prized education and intellectual independence, unusual for girls of that era.

Austrian universities did not formally admit women until 1897. Meitner studied privately to pass her matriculation exam and then enrolled at the University of Vienna, where she was mentored by the physicist Ludwig Boltzmann, whose enthusiasm for atomic theory shaped her scientific worldview. In 1906 she became only the second woman to earn a doctorate in physics from the university.

In 1907 Meitner moved to Berlin, ostensibly for a short stay to hear lectures by Max Planck. She stayed for over three decades. There she began a lifelong scientific partnership with the chemist Otto Hahn, working initially in a converted carpentry shop at the Kaiser Wilhelm Institute for Chemistry because women were barred from the main laboratories.

Major Breakthroughs, Works & Milestones

Meitner and Hahn built one of the era’s most productive research partnerships, discovering the element protactinium in 1917 and advancing the study of radioactivity and nuclear physics. By the 1920s and 1930s, Meitner led her own physics section at the Kaiser Wilhelm Institute, one of very few women in Germany to hold such a position, and was appointed professor at the University of Berlin in 1926.

• 1917: Co-discovery of the element protactinium with Otto Hahn
• 1926: First female physics professor in Germany
• 1938: Forced to flee Nazi Germany due to Jewish ancestry, settling in Stockholm
• December 1938: Correctly interprets Hahn and Fritz Strassmann’s experimental results as nuclear fission, working with nephew Otto Frisch in Sweden
• 1939: Publishes the theoretical explanation of fission in Nature, coining the term “fission”
• 1944: Otto Hahn awarded the Nobel Prize in Chemistry solely for the discovery, a decision widely regarded today as a historic injustice
• 1966: Awarded the Enrico Fermi Award jointly with Hahn and Strassmann

The critical breakthrough came after Meitner’s exile. Hahn and Strassmann in Berlin found puzzling results when bombarding uranium with neutrons, and secretly corresponded with Meitner, now a refugee in Sweden. Walking in the snow near Kungälv with her nephew Otto Frisch on Christmas 1938, Meitner realised the uranium nucleus had split into lighter elements, releasing enormous energy in line with Einstein’s E=mc². This insight—delivered without access to a laboratory, funding, or German citizenship—became the theoretical foundation of nuclear fission.

Historical Context: Germany and Global Impact

Meitner’s career unfolded against the collapse of the German university system’s openness and the rise of Nazi racial laws. Despite her scientific stature and Austrian citizenship, the 1938 Anschluss stripped her of protection, forcing a harrowing, illegal border crossing into the Netherlands with only ten Reichsmarks and a few belongings. She never returned to live in Germany.

Her discovery arrived just before the outbreak of the Second World War and directly informed the science behind the Manhattan Project, though Meitner herself refused to work on the atomic bomb, later stating she would have nothing to do with a weapon of such destruction. The dropping of the bombs on Hiroshima and Nagasaki in 1945, built on principles she had helped explain, weighed heavily on her for the rest of her life.

Complex Legacy, Ethical Debates & Controversies

The 1944 Nobel Prize in Chemistry, awarded to Hahn alone, remains one of the most cited cases of a woman’s scientific contribution being erased. Historians largely agree that Meitner’s theoretical interpretation was indispensable to the discovery, and that gender bias, her forced absence from Germany, and Hahn’s own reticence about crediting a Jewish former colleague under Nazi-era political pressures all played a role in her exclusion.

Meitner was nominated for the Nobel Prize numerous times in both physics and chemistry over subsequent decades but never won. She has instead become a symbol invoked in debates over the recognition of women in STEM fields, and her name was given to element 109, meitnerium, in 1997—one of the few elements named after a woman.

Memorials, Museums & Where to Experience This History Today

Visitors to Berlin can explore Meitner’s legacy at several sites connected to her decades of research:

• Hahn-Meitner-Platz, Berlin-Wedding: A square and nearby institute named jointly for the two scientists, close to the former Kaiser Wilhelm Institute grounds.
• Deutsches Museum, Munich: Exhibits on nuclear physics history featuring Meitner’s role, general admission around €15.
• Museum für Naturkunde, Berlin: Displays touching on early twentieth-century German physics and the Kaiser Wilhelm Society.
• Humboldt University of Berlin: Commemorative plaques mark buildings where Meitner lectured before 1938.
• Lise Meitner grave, Bramley, England: She died on 27 October 1968 in Cambridge, England, and is buried in the village of Bramley; her tombstone reads, “Lise Meitner: a physicist who never lost her humanity.”
