Complete Biography

Origins And Childhood

Born in Vienna to a secular Jewish family headed by lawyer Philipp Meitner and Hedwig Skovran, Lise Meitner grew up in an intellectually vibrant environment. She excelled at mathematics, pursued private tutoring to pass the state examination that opened university studies to women, and entered the University of Vienna in 1901. There she studied under Ludwig Boltzmann, whose lectures on thermodynamics and kinetic theory shaped her scientific approach. In 1906 she completed a doctorate on heat conduction in inhomogeneous solids, becoming the university’s second female physics PhD.

Historical Context

The early twentieth century brought revolutionary discoveries in physics—X-rays, radioactivity, and quantum theory—while European universities remained restrictive toward women and Jews. Moving to Berlin in 1907, Meitner found opportunities at the University of Berlin and the Kaiser Wilhelm Society’s new institutes, yet she initially worked unpaid and entered through servant entrances. World War I, the collapse of empires, and the Nazi seizure of power later disrupted research networks. Anti-Jewish laws enacted after 1933 pushed Meitner and many other scientists into exile.

Public Ministry

Meitner’s thirty-year partnership with chemist Otto Hahn defined her Berlin career. Together they investigated radioactive decay series, combining Hahn’s chemical separations with Meitner’s physical measurements. In 1917, joined by Otto von Baeyer, they isolated protactinium-231. During the 1920s she became a leading authority on beta and gamma radiation, publishing influential papers and gaining appointment as a full professor of physics at the University of Berlin in 1926.

Teachings And Message

As a teacher, Meitner emphasized precision and collaboration. Her lectures stressed the unity of nuclear physics and chemistry, encouraging students to relate experimental evidence to theoretical insight. She championed ethical conduct, insisting on proper attribution and cautioning that scientists must consider the societal consequences of their work, especially after fission’s discovery.

Activity In Galilee

Her Berlin years were marked by meticulous experiments in the Kaiser Wilhelm Institute’s basement laboratories. Meitner and Hahn designed shielded facilities to detect faint radioactivity, refined Geiger counter measurements, and advanced ionization chamber techniques. Her data on beta spectra influenced theoretical debates leading to Wolfgang Pauli’s neutrino hypothesis. Regular interactions with Niels Bohr, James Chadwick, and Enrico Fermi underscored her international stature.

Journey To Jerusalem

The 1938 Anschluss stripped Meitner of Austrian citizenship and left her vulnerable in Berlin. With assistance from Dutch and Danish colleagues, she escaped to the Netherlands and then to Sweden, joining Manne Siegbahn’s Nobel Institute. Despite limited resources, she analyzed Hahn and Fritz Strassmann’s puzzling results on neutron-irradiated uranium. During a snowy walk with her nephew Otto Robert Frisch in December 1938, she realized that the nucleus could split; together they coined ‘fission’ and calculated its energy release in early 1939.

Sources And Attestations

Meitner’s scientific papers, institutional records from the Kaiser Wilhelm Society, and extensive correspondence with contemporaries such as Niels Bohr and James Franck document her contributions. Oral histories collected by the American Institute of Physics in the 1960s and testimonies from students and colleagues confirm her role as both pioneering physicist and ethical voice. Archival materials in Berlin, Vienna, Stockholm, and Washington, D.C., provide detailed evidence of her career and exile.

Historical Interpretations

Scholars interpret Meitner as a bridge between classical radioactivity research and modern nuclear physics. Biographers Ruth Lewin Sime and Patricia Rife highlight gender and political barriers that limited recognition of her achievements, including the Nobel exclusion. Studies of scientific migration underscore her experience as emblematic of Nazi-era exile. Histories of nuclear physics credit her theoretical interpretation of fission as crucial to the field’s development.

Legacy

After World War II, Meitner advocated peaceful applications of nuclear energy, accepted the 1966 Enrico Fermi Award with Hahn and Frisch, and supported women scientists. The element meitnerium (109) honors her, and scholarships, societies, and university chairs bearing her name promote equity in science. Her gravestone’s inscription—‘A physicist who never lost her humanity’—encapsulates her enduring reputation.

Frequently Asked Questions

She was born on 7 November 1878 in Vienna and died on 27 October 1968 in Cambridge, United Kingdom.

She co-discovered protactinium, interpreted nuclear fission with Otto Robert Frisch, and helped lay the foundations of nuclear physics.

Anti-Jewish laws under the Nazi regime forced her to flee Berlin in 1938; she resettled in Sweden.

No. The 1944 Nobel Prize in Chemistry went solely to Otto Hahn for fission, and her omission remains widely criticized.

Meitner declined invitations to join the Manhattan Project and urged scientists to take moral responsibility for nuclear technology.
