She was the aunt of Otto Robert Frisch. Her father was Philipp Meitner.

Lise Meitner (7 November 1878 – 27 October 1968) was an Austrian physicist who worked on radioactivity and nuclear physics.[4] Meitner was part of the Hahn-Meitner-Strassmann team that worked on "transuranium-elements" from 1935 onward, which led to the radiochemical discovery of the nuclear fission of uranium and thorium in December 1938, an achievement for which her colleague Otto Hahn was awarded the Nobel Prize for Chemistry in 1944.[5] Meitner is often mentioned as one of the most glaring examples of women's scientific achievement being overlooked by the Nobel committee.[6][7][8]

A 1997 Physics Today study concluded that Meitner's omission was "a rare instance in which personal negative opinions apparently led to the exclusion of a deserving scientist" from the Nobel.[9] Element 109, meitnerium, is named in her honour.[10][11][12]

Early years[edit]

Meitner in 1906

Meitner was born into a Jewish family as the third of eight children in Vienna, 2nd district (Leopoldstadt). Her father, Philipp Meitner,[13] was one of the first Jewish lawyers in Austria.[8] She was born on 7 November 1878. She shortened her name from Elise to Lise.[14] The birth register of Vienna's Jewish community lists Meitner as being born on 17 November 1878, but all other documents list it as 7 November, which is what she used.[1] As an adult, she converted to Christianity, following Lutheranism,[1][15] and was baptized in 1908.[16]


Women were not allowed to attend public institutions of higher education in Vienna around 1900, but Meitner was able to achieve a private education in physics in part because of her supportive parents, and she completed in 1901 with an "externe Matura" examination at the Akademisches Gymnasium.[3][17]

Meitner studied physics and went on to became the second woman to obtain a doctoral degree in physics at the University of Vienna in 1905 (her dissertation was on "heat conduction in an inhomogeneous body").[8] After she received her doctorate, Meitner rejected an offer to work in a gas lamp factory. Encouraged by her father and backed by his financial support, she went to the Friedrich-Wilhelms-Universität in Berlin where famous physicist Max Planck allowed her to attend his lectures, an unusual gesture by Planck, who until then had rejected any woman wanting to attend his lectures.[citation needed]

Scientific career[edit]

After one year of attending Planck's lectures, Meitner became Planck's assistant. During the first years she worked together with chemist Otto Hahn and together with him discovered several new isotopes. In 1909 she presented two papers on beta-radiation.

In 1912 the research group Hahn–Meitner moved to the newly founded Kaiser-Wilhelm-Institute (KWI) in Berlin-Dahlem, south west in Berlin. She worked without salary as a "guest" in Hahn's department of Radiochemistry. It was not until 1913, at 35 years old and following an offer to go to Prague as associate professor, that she got a permanent position at KWI.

In the first part of World War I, she served as a nurse handling X-ray equipment. She returned to Berlin and her research in 1916, but not without inner struggle. She felt in a way ashamed of wanting to continue her research efforts when thinking about the pain and suffering of the victims of war and their medical and emotional needs.[18]

Lise Meitner and Otto Hahn in their laboratory.

In 1917, she and Hahn discovered the first long-lived isotope of the element protactinium, for which she was awarded the Leibniz Medal by the Berlin Academy of Sciences. That year, Meitner was given her own physics section at the Kaiser Wilhelm Institute for Chemistry.[8]

In 1922, she discovered the cause, known as the Auger effect, of the emission from surfaces of electrons with 'signature' energies.[19] The effect is named for Pierre Victor Auger, a French scientist who independently discovered the effect in 1923.[20]

In 1926, Meitner became the first woman in Germany to assume a post of full professor in physics, at the University of Berlin. In 1935, as head of the physics department of the Kaiser Wilhelm Institute for Chemistry in Berlin-Dahlem (today "Hahn-Meitner-Building of the Free University) she and Otto Hahn, the director of the KWI, undertook the so called "transuranium research" program. This program eventually led to the unexpected discovery of the nuclear fission of heavy nuclei in December 1938, half a year after she had left Berlin. She was praised by Albert Einstein as the "German Marie Curie".[8][21][22]

While at the Kaiser Wilhelm Institute, Meitner corresponded with James Chadwick at the Cavendish Laboratory in Cambridge. As Chadwick and others were attempting to prove the existence of the neutron, Meitner sent polonium to Chadwick for his experiments. Chadwick eventually required and received more polonium for his experiments from a hospital in Baltimore, but he would remain grateful to Meitner.[23] Later, he said he was "quite convinced that [Meitner] would have discovered the neutron if it had been firmly in her mind, if she had had the advantage of, say, living in the Cavendish for years, as I had done."[24]

In 1930, Meitner taught a seminar on nuclear physics and chemistry with Leó Szilárd. After the discovery of the neutron in the early 1930s, the scientific community speculated that it might be possible to create elements heavier than uranium (atomic number 92) in the laboratory. A scientific race began between the teams of Ernest Rutherford in Britain, Irène Joliot-Curie in France, Enrico Fermi in Italy, and the Meitner–Hahn team in Berlin. At the time, all concerned believed that this was abstract research for the probable honour of a Nobel prize. None suspected that this research would culminate in nuclear weapons.

When Adolf Hitler came to power in 1933, Meitner was still acting as head of the physics department of the Kaiser Wilhelm Institute for Chemistry. Although she was protected by her Austrian citizenship, all other Jewish scientists, including her nephew Otto Frisch, Fritz Haber, Leó Szilárd and many other eminent figures, were dismissed or forced to resign from their posts. Most of them emigrated from Germany. Her response was to say nothing and bury herself in her work. After the Anschluss in March 1938, her situation became difficult. On July 13, 1938, Meitner, with the support of Otto Hahn and the help from the Dutch physicists Dirk Coster and Adriaan Fokker, departed for the Netherlands. She was forced to travel under cover to the Dutch border, where Coster persuaded German immigration officers that she had permission to travel to the Netherlands. She reached safety, though without her possessions. [25] Meitner later said that she left Germany forever with 10 marks in her purse. Before she left, Otto Hahn had given her a diamond ring he had inherited from his mother: this was to be used to bribe the frontier guards if required. It was not required, and Meitner's nephew's wife later wore it.

An appointment at the University of Groningen did not come through, and she went instead to Stockholm, where she took up a post at Manne Siegbahn's laboratory, despite the difficulty caused by Siegbahn's prejudice against women in science. Here she established a working relationship with Niels Bohr, who travelled regularly between Copenhagen and Stockholm. She continued to correspond with Hahn and other German scientists.[26]

Nuclear fission[edit]

On occasion of a lecture by Hahn in Niels Bohr's Institute he, Bohr, Meitner and Frisch met in Copenhagen on November 10, 1938. Later they continued to exchange a series of letters. In December Hahn and his assistant Fritz Strassmann performed the difficult experiments which isolated the evidence for nuclear fission at their laboratory in Berlin-Dahlem. The surviving correspondence shows that Hahn recognized that 'fission' was the only explanation for the proof of barium (at first he named the process a 'bursting' of the uranium), but, baffled by this remarkable conclusion, he wrote to Meitner. The possibility that uranium nuclei might break up under neutron bombardment had been suggested years before, notably by Ida Noddack in 1934. However, by employing the existing "liquid-drop" model of the nucleus,[27] Meitner and Frisch, exclusively informed by Hahn in advance, were therefore the first to articulate a theory of how the nucleus of an atom could be split into smaller parts: uranium nuclei had split to form barium and krypton, accompanied by the ejection of several neutrons and a large amount of energy (the latter two products accounting for the loss in mass). She and Frisch had discovered the reason that no stable elements beyond uranium (in atomic number) existed naturally; the electrical repulsion of so many protons overcame the strong nuclear force.[27] Frisch and Meitner also first realized that Einstein's famous equation, E = mc2, explained the source of the tremendous releases of energy in nuclear fission, by the conversion of rest mass into kinetic energy, popularly described as the conversion of mass into energy. Ironically, Meitner was motivated to begin these calculations in order to show that Irene Joliot-Curie's interpretation of some experiments violated the liquid drop model.

A letter from Bohr, commenting on the fact that the amount of energy released when he bombarded uranium atoms was far larger than had been predicted by calculations based on a non-fissile core, had sparked the above inspiration in December 1938. But Meitner and Frisch later confirmed that chemistry had been solely responsible for the discovery, although Hahn, as a chemist, was reluctant to explain the fission process in correct physical terms.

In a later appreciation Lise Meitner wrote:[28]

The discovery of nuclear fission by Otto Hahn and Fritz Strassmann opened up a new era in human history. It seems to me that what makes the science behind this discovery so remarkable is that it was achieved by purely chemical means.

And in an interview with the West German television (ARD, March 8, 1959) Meitner said:[29]

Otto Hahn and Fritz Strassmann were able to do this by exceptionally good chemistry, fantastically good chemistry, which was way ahead of what any one else was capable of at that time. The Americans learned to do it later. But at that time, Hahn and Strassmann were really the only ones who could do it. And that was because they were such good chemists. Somehow they really succeeded in using chemistry to demonstrate and prove a physical process.

Fritz Strassmann responded in the same interview with this clarification:[29]

Professor Meitner stated that the success could be attributed to chemistry. I have to make a slight correction. Chemistry merely isolated the individual substances, it did not precisely identify them. It took Professor Hahn's method to do this. This is where his achievement lies.

Hahn and Strassmann had sent the manuscript of their first paper to Naturwissenschaften in December 1938, reporting they had detected and identified the element barium after bombarding uranium with neutrons;[30] simultaneously, Hahn had communicated their results exclusively to Meitner in several letters, and did not inform the physicists in his own institute.

In their second publication on the evidence of barium (Die Naturwissenschaften, 10 February 1939) Hahn and Strassmann used for the first time the name Uranspaltung (Uranium fission) and predicted the existence and liberation of additional neutrons during the fission process (which was proved later to be a chain reaction by Frédéric Joliot and his team). Lise Meitner and her nephew Otto Frisch were the first who correctly interpreted Hahn's and Strassmann's results as being nuclear fission, a term coined by Frisch, and published their paper in Nature.[31] Frisch confirmed this experimentally on 13 January 1939.[32]

These three reports, the first Hahn-Strassmann publication of January 6, 1939, the second Hahn-Strassmann publication of February 10, 1939, and the Frisch-Meitner publication of February 11, 1939, had electrifying effects on the scientific community. Because there was a possibility that fission could be used as a weapon, and since the knowledge was in German hands, Leó Szilárd, Edward Teller, and Eugene Wigner jumped into action, persuading Albert Einstein, a celebrity, to write President Franklin D. Roosevelt a letter of caution. In 1940 Frisch and Rudolf Peierls produced the Frisch–Peierls memorandum, which first set out how an atomic explosion could be generated, and this ultimately led to the establishment in 1942 of the Manhattan Project. Meitner refused an offer to work on the project at Los Alamos, declaring "I will have nothing to do with a bomb!"[33] Meitner said that Hiroshima had come as a surprise to her, and that she was "sorry that the bomb had to be invented."[34]

In Sweden, Meitner was first active at Siegbahn's Nobel Institute for Physics, and at the Swedish Defence Research Establishment (FOA) and the Royal Institute of Technology in Stockholm, where she had a laboratory and participated in research on R1, Sweden's first nuclear reactor. In 1947, a personal position was created for Meitner at the University College of Stockholm with the salary of a professor and funding from the Council for Atomic Research.[35]

Awards and honours[edit]

On 15 November 1945 the Royal Swedish Academy of Sciences announced that Otto Hahn had been awarded the 1944 Nobel Prize in Chemistry for "his discovery of the fission of heavy atomic nuclei."[36]

"Surely Hahn fully deserved the Nobel Prize for chemistry. There is really no doubt about it. But I believe that Otto Robert Frisch and I contributed something not insignificant to the clarification of the process of uranium fission—how it originates and that it produces so much energy and that was something very remote to Hahn," wrote Lise Meitner to her friend B. Broomé-Aminoff in November 1945.[37]

And Carl Friedrich von Weizsäcker, Lise Meitner's former assistant, later added: "He certainly did deserve this Nobel Prize. He would have deserved it even if he had not made this discovery. But everyone recognized that the splitting of the atomic nucleus merited a Nobel Prize."[38] Also Otto Robert Frisch shared this opinion in a letter to Carl Seelig.[39]

Some American historians, who have documented their view of the discovery of nuclear fission, believe Meitner should have been awarded the Nobel Prize with Hahn.[40][41][42]

On a visit to the USA in 1946, she received the honor of "Woman of the Year" by the National Press Club and had dinner with President Harry Truman and others at the Women's National Press Club. She lectured at Princeton, Harvard and other US universities, and was awarded a number of honorary doctorates. Meitner refused to move back to Germany, and enjoyed retirement and research in Stockholm until her relocation to Cambridge, England in 1960. She received jointly with Hahn the Max Planck Medal of the German Physical Society in 1949, and in 1955 she was awarded the first Otto Hahn Prize of the German Chemical Society. In 1957 the German President Theodor Heuss awarded her the highest German order for scientists, the peace class of the Pour le mérite. She was nominated by Otto Hahn for both honors. Meitner's name was submitted, also by Hahn, to the Nobel Prize committee more than ten times, but she was not accepted. An even rarer honor was given to her in 1997 when element 109 was named meitnerium in her honor.[8][43][44] Named after Meitner were the Hahn–Meitner-Institut in Berlin, craters on the Moon and on Venus, and a main-belt asteroid.

Meitner was elected a foreign member of the Royal Swedish Academy of Sciences in 1945, and had her status changed to that of a Swedish member in 1951. Four years later she was elected a Foreign Member of the Royal Society (ForMemRS) in 1955.[3] She was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1960.[45]

In 1966 Hahn, Fritz Strassmann and Meitner were jointly awarded the Enrico Fermi Award by President Lyndon B. Johnson and the United States Atomic Energy Commission (USAEC) in Washington D.C. Lise Meitner's diploma bears the words: "For pioneering research in the naturally occurring radioactivities and extensive experimental studies leading to the discovery of fission." Otto Hahn's diploma is similar but essentially different: "For pioneering research in the naturally occurring radioactivities and extensive experimental studies culminating in the discovery of fission."[46]

Meitner received 21 scientific honors and awards for her work (including 5 honorary doctorates and membership of 12 academies). In 1947 she received the Award of the City of Vienna for science. She was the first female member of the scientific class of the Austrian Academy of Sciences. In 2008, the NBC defense school of the Austrian Armed Forces established the "Lise Meitner" award.

In 1960, Meitner was awarded the Wilhelm Exner Medal and in 1967, the Austrian Decoration for Science and Art.

In July 2014 a statue of Lise Meitner was unveiled in the garden of the Humboldt University of Berlin next to similar statues of Hermann von Helmholtz and Max Planck.[47]

Schools and streets were named after her in many cities in Austria and Germany.

The European Physical Society awards the "Lise Meitner Prize" for excellent research in nuclear science.[48] In Sweden the "Gothenburg Lise Meitner Award" is awarded annually by the Gothenburg Physics Center to a scientist who has made a breakthrough in physics.[49]

Later years[edit]

After the war, Meitner, while acknowledging her own moral failing in staying in Germany from 1933 to 1938, was bitterly critical of Hahn, Max von Laue and other German scientists who, she thought, would have collaborated with the Nazis and done nothing to protest against the crimes of Hitler's regime. Referring to the leading German nuclear physicist Werner Heisenberg, she said: "Heisenberg and many millions with him should be forced to see these camps and the martyred people." She wrote to Hahn:

Meitner's grave in Bramley

You all worked for Nazi Germany. And you tried to offer only a passive resistance. Certainly, to buy off your conscience you helped here and there a persecuted person, but millions of innocent human beings were allowed to be murdered without any kind of protest being uttered ... [it is said that] first you betrayed your friends, then your children in that you let them stake their lives on a criminal war – and finally that you betrayed Germany itself, because when the war was already quite hopeless, you did not once arm yourselves against the senseless destruction of Germany.

— [50]

Hahn received this letter but it did not harm his friendship with Meitner, because he knew that she had no idea at all of the real existing situation in the Nazi era after her escape in July 1938. After the war in the 1950s and 1960s, Lise Meitner again enjoyed visiting Germany and staying with Hahn and his family for several days on different occasions, particularly on March 8, 1959, to celebrate Hahn's 80th birthday in Göttingen, where she addressed recollections in his honour. Also Hahn wrote in his memoirs, which were published shortly after his death in 1968, that he and Lise Meitner had remained lifelong close friends.[51]

Meitner became a Swedish citizen in 1949. She retired in 1960 and moved to the UK where most of her relatives were, although she continued working part-time and giving lectures. A strenuous trip to the United States in 1964 led to Meitner having a heart attack, from which she spent several months recovering. Her physical and mental condition weakened by atherosclerosis, she was unable to travel to the US to receive the Enrico Fermi prize and relatives had to present it to her. After breaking her hip in a fall and suffering several small strokes in 1967, Meitner made a partial recovery, but eventually was weakened to the point where she moved into a Cambridge nursing home. She died on 27 October 1968 at the age of 89. Meitner was not informed of the deaths of Otto Hahn (d. July 1968) or his wife Edith, as her family believed it would be too much for someone so frail.[4] As was her wish, she was buried in the village of Bramley in Hampshire, at St. James parish church, close to her younger brother Walter, who had died in 1964. Her nephew Otto Frisch composed the inscription on her headstone. It reads "Lise Meitner: a physicist who never lost her humanity". A short residential street in the village is named "Meitner Close".
