Lise Meitner: The Woman Who Split the Atom But Was Denied the Nobel.
Lise Meitner’s name often sparks curiosity. Known for her groundbreaking explanation of nuclear fission and being overlooked for the Nobel Prize, her life story is one of extraordinary intellect, resilience, and societal skepticism toward women and Jewish scientists amid Nazi persecution.
Who Is Lise Meitner?
Lise Meitner was an Austrian-Swedish physicist renowned for her contributions to radioactivity and nuclear physics. Born on November 7, 1878, in Vienna, Austria-Hungary, into a Jewish family as the third of eight children, she grew up in an intellectually stimulating environment encouraged by her father, Philipp Meitner, a lawyer and chess master.
Facing barriers to women’s education, she privately prepared for university and earned a doctorate in physics from the University of Vienna in 1906, becoming the second woman to do so there.
In 1907, she moved to Berlin to collaborate with chemist Otto Hahn at the Kaiser Wilhelm Institute, where they discovered protactinium and advanced isotope research. A Lutheran convert since 1908, Meitner drew inspiration from mentors like Max Planck and Ludwig Boltzmann, becoming the first female full professor of physics in Germany in 1926 at the University of Berlin.
Her work during World War I included serving as an X-ray nurse, and she later refused involvement in atomic bomb development.

The Nuclear Fission Discovery: A Defining Moment.
In 1938–1939, Meitner’s reputation transcended her Berlin lab when she and her nephew Otto Robert Frisch provided the theoretical explanation for nuclear fission, following experiments by Hahn and Fritz Strassmann.
The incident:
From 1934, Meitner, Hahn, and Strassmann bombarded uranium with neutrons, initially misinterpreting results as transuranic elements. Forced to flee Nazi Germany in July 1938 due to her Jewish heritage, Meitner escaped to Sweden with help from Dutch physicists. Hahn and Strassmann continued, detecting barium in December 1938 and informing Meitner by letter. Over Christmas in Kungälv, she and Frisch walked in the snow, applying the liquid-drop model to explain the uranium nucleus splitting into lighter elements, releasing 200 MeV of energy via E=mc². Frisch coined “fission” and confirmed it experimentally in January 1939. Their paper appeared in Nature on February 11, 1939, but Hahn received sole credit for the 1944 Nobel Prize in Chemistry.
Meitner’s response was measured: She acknowledged Hahn’s chemical work but emphasized her and Frisch’s physical interpretation. The oversight sparked debates, with nominators like Niels Bohr advocating for her. Decades later, it’s cited as a prime example of gender and ethnic bias in science, inspiring calls for recognition reform.
Why Did People Get It Wrong?
Meitner attributed the Nobel exclusion and downplaying of her role to ingrained flaws in how scientific institutions approached credit and diversity. She argued that:
- People “reset” the narrative: Once fission was framed as a chemical discovery, assumptions of Hahn’s sole authorship persisted, treating physics contributions as secondary.
- Systemic biases are deceptive: The prestige of the Nobel masked underlying sexism and antisemitism, making it seem merit-based when wartime politics and disciplinary silos favored men and non-Jews.
- Education and awareness play a role: Meitner believed global systems discouraged recognition of interdisciplinary and female-led work, leaving many unable to navigate the counterintuitive reality that a Jewish woman in exile drove the breakthrough.
The Cost of Being a Pioneer.
For Meitner, her genius was both a gift and a burden. Despite her achievements, she often felt isolated and undervalued, especially in Sweden where Manne Siegbahn provided minimal support amid anti-refugee sentiments.
As she reflected in letters, the Nazi era forced her into exile, separating her from her lab and family, with relatives like her brother-in-law imprisoned in Dachau.
Her refusal to join the Manhattan Project stemmed from ethical concerns—“I will have nothing to do with a bomb!”—requiring her to fight twice as hard not just against scientific challenges, but against erasure and persecution. Her experiences highlight the societal challenges faced by women in STEM who dare to innovate under oppression.
The Legacy of Lise Meitner.
Lise Meitner’s life reminds us of the importance of equitable recognition and ethical science. Her fission work serves as a cautionary tale about dismissing marginalized contributions too quickly. She continues to inspire through posthumous honors like element 109, meitnerium (named in 1997), and the European Physical Society’s Lise Meitner Prize (established 2000). Through initiatives like the Gothenburg Lise Meitner Award and lectures named after her, she proves brilliance isn’t just about discoveries—it’s about enduring skepticism with grace.
Her accolades, including the Max Planck Medal (1949, shared with Hahn), Enrico Fermi Award (1966, shared with Hahn and Strassmann), and honorary doctorates from institutions like the University of Rochester, underscore her impact. Meitner lectured worldwide, including in the U.S. post-World War II, and her story has been featured in books like Marissa Moss’s biography and podcasts like Lost Women of Science. She tied her research to broader themes of humanity, criticizing scientists’ complicity under Nazism.

What Can We Learn?
The story of Lise Meitner is more than a scientist’s anecdote. It challenges us to rethink how we approach recognition, diversity, and ethics in science. Are we nurturing talents from all backgrounds capable of seeing beyond biases? Or are we limiting potential by clinging to outdated exclusions?
Meitner’s advice: “Stay selfless in the pursuit of truth, and accept reality with wonder and admiration.”
“Science makes people reach selflessly for truth and objectivity; it teaches people to accept reality, with wonder and admiration, not to mention the deep reverence for the laws of Nature.”
