Krakowskie Przedmieście 66, nearWarsaw’s Old Town (in the distance). It was here, in 1890–91, that Skłodowska conducted her first scientific work.

Maria made an agreement with her sister, Bronisława, that she would give her financial assistance during Bronisława’s medical studies in Paris, in exchange for similar assistance two years later.^[8] In connection with this, she took a position as governess. First with a lawyer’s family in Kraków, then for two years inCiechanów with a landed family, the Żorawskis, who were relatives of her father. While working for the latter family, she fell in love with their son, Kazimierz Żorawski, which was reciprocated by this future eminent mathematician. His parents, however, rejected the idea of his marrying the penniless relative and Kazimierz was unable to oppose them. Maria lost her position as governess.

.

Kazimierz Żorawski, in later life

At the beginning of 1890, Bronisława, a few months after she married Kazimierz Dłuski, invited Maria to join them in Paris. Maria declined because she could not afford the university tuition and was still counting on marrying Kazimierz Żorawski. She returned home to her father, with whom she remained till the Fall of 1891, tutoring, studying at the clandestine Floating University, and beginning her practical scientific training in a laboratory at the Museum of Industry and Agriculture. It was run by her cousin Józef Boguski, who had been assistant in St. Petersburg to the great Russian chemist Dmitri Mendeleyev.^[10]
In October 1891, at her sister’s insistence and after receiving a letter from Żorawski, in which he definitively broke his relationship with her, she decided to go to France after all.^[5]
Maria’s loss of the relationship with Żorawski was tragic for both. He soon earned a doctorate and pursued an academic career as a mathematician, becoming a professor and rector of Kraków University and president of the Warsaw Society of Learning. Still, as an old man and a mathematics professor at the Warsaw Polytechnic, he would sit contemplatively in front of the statue of Maria Skłodowska, which had been placed before the Radium Institute that she had founded.^[11] In Paris, Maria briefly found ****ter with her sister and brother-in-law before renting a primitive garret ^[12] and proceeding with her studies of physics, chemistry, and mathematics at the Sorbonne (the University of Paris).

Pierre Curie

Skłodowska studied during the day and tutored evenings, barely earning her keep. In 1893 she was awarded a degree in physics and began work in an industrial laboratory at Lippman’s. Meanwhile she continued studying at the Sorbonne, and in 1894, earned a degree in mathematics.
In the same year Pierre Curie entered her life. He was an instructor in the School of Physics and Chemistry, the École Supérieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI). Skłodowska had begun her scientific career in Paris with an investigation of the magnetic properties of various steels; it was their mutual interest in magnetism that drew Skłodowska and Curie together.^[13]
Her departure for the summer to Warsaw only enhanced their mutual feelings for each other. She still was laboring under the illusion that she would be able to return to Poland and work in her chosen field of study. When she was denied a place at Kraków University merely because she was a woman,^[14] however, she returned to Paris. Almost a year later, in July 1895, she and Pierre Curie married, and thereafter the two physicists hardly ever left their laboratory. They shared two hobbies, long bicycle trips and journeys abroad, which brought them even closer. Maria had found a new love, a partner, and scientific collaborator upon whom she could depend.^[14]

New elements

The idea [writes Reid] was her own; no one helped her formulate it, and although she took it to her husband for his opinion she clearly established her ownership of it. She later recorded the fact twice in her biography of her husband to ensure there was no chance whatever of any ambiguity. It [is] likely that already at this early stage of her career [she] realized that… many scientists would find it difficult to believe that a woman could be capable of the original work in which she was involved.^[18]

In her systematic search for other substances beside uranium salts that emitted radiation, Skłodowska–Curie had found that the element thorium likewise, was radioactive.

She was acutely aware of the importance of promptly publishing her discoveries and thus establishing her priority. Had not Becquerel, two years earlier, presented his discovery to the Académie des Sciences the day after he made it, credit for the discovery of radioactivity, and even a Nobel Prize, would have gone to Silvanus Thompson instead. Skłodowska–Curie chose the same rapid means of publication. Her paper, giving a brief and simple account of her work, was presented for her to the Académie on 12 April 1898 by her former professor, Gabriel Lippmann.^[19]
Even so, just as Thompson had been beaten by Becquerel, so Skłodowska–Curie was beaten in the race to tell of her discovery that thorium gives off rays in the same way as uranium. Two months earlier, Gerhard Schmidt had published his own finding in Berlin.^[20]
At that time, however, no one else in the world of physics had noticed what Skłodowska–Curie recorded in a sentence of her paper, describing how much greater were the activities of pitchblende and chalcolite compared to uranium itself: “The fact is very remarkable, and leads to the belief that these minerals may contain an element which is much more active than uranium.” She later would recall how she felt “a passionate desire to verify this hypothesis as rapidly as possible.”^[21]
Pierre Curie was sure that what she had discovered was not a spurious effect. He was so intrigued that he decided to drop his work on crystals temporarily and to join her. On 14 April 1898 they optimistically weighed out a 100-gram sample of pitchblende and ground it with a pestle and mortar. They did not realize at the time that what they were searching for was present in such minute quantities that they eventually would have to process tonnes of the ore.^[21]
Since they were unaware of the deleterious effects of radiation exposure attendant on their chronic unprotected work with radioactive substances, Skłodowska–Curie and her husband had no idea what price they would pay for the effect of their research upon their health.^[14]

Pierre, Irène, Marie Curie

In 1903, the Royal Swedish Academy of Sciences awarded Pierre Curie, Marie Curie and Henri Becquerel the Nobel Prize in Physics, “in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel.”
Skłodowska–Curie and her husband were unable to go to Stockholm to receive the prize in person, but they shared its financial proceeds with needy acquaintances, including students.^[14]
On receiving the Nobel Prize, Marie and Pierre Curie suddenly became very famous. The Sorbonne gave Pierre a professorship and permitted him to establish his own laboratory, in which Skłodowska–Curie became the director of research.
In 1897 and 1904, respectively, Skłodowska–Curie gave birth to their daughters, Irène and Eve Curie. She later hired Polish governesses to teach her native ******** to them, and send or take them on visits to Poland.^[26]

On 19 April 1906 Pierre was killed in a street accident. Walking across the Rue Dauphine in heavy rain, he was struck by a horse-drawn vehicle and fell under its wheels, his skull was fractured. While it has been speculated that previously, he may have been weakened by prolonged radiation exposure, it has not been proven that this was the cause of the accident.
Skłodowska–Curie was devastated by the death of her husband. She noted that, as of that moment she suddenly had become “an incurably and wretchedly lonely person”. On 13 May 1906 the Sorbonne physics department decided to retain the chair that had been created for Pierre Curie and they entrusted it to Skłodowska–Curie together with full authority over the laboratory. This allowed her to emerge from Pierre’s shadow. She became the first woman to become a professor at the Sorbonne, and in her exhausting work regime, sought a meaning for her life.

Paul Langevin in later life

Recognition for her work grew to new heights, and in 1911 the Royal Swedish Academy of Sciences awarded her a second Nobel Prize, this time for Chemistry. A delegation of celebrated Polish men of learning, headed by world-famous novelist, Henryk Sienkiewicz, encouraged her to return to Poland and continue her research in her native country.^[14]

In 1911, it was revealed that during 1910–11 Skłodowska–Curie had conducted an affair of about a year’s duration with physicist Paul Langevin, a former student of Pierre Curie.^[28] He was a married man who was estranged from his wife. This resulted in a press scandal that was exploited by her academic opponents. Despite her fame as a scientist working for France, the public’s attitude tended toward xenophobia—the same that had led to the Dreyfus Affair-which also fueled false speculation that Skłodowska–Curie was Jewish. She was five years older than Langevin and was portrayed in the tabloids as a home-wrecker.^[29] Later, Skłodowska–Curie’s granddaughter, Hélène Joliot, married Langevin’s grandson, Michel Langevin.
Skłodowska–Curie’s second Nobel Prize, in 1911, enabled her to talk the French government into funding the building of a private Radium Institute (Institut du radium, now the Institut Curie), which was built in 1914 and at which research was conducted in chemistry, physics, and medicine. The Institute became a crucible of Nobel Prize winners, producing four more, including her daughter Irène Joliot-Curie and her son-in-law, Frédéric Joliot-Curie.

World War I

During World War I, Skłodowska-Curie pushed for the use of mobile radiography units, which came to be popularly known as petites Curies (“Little Curies”), for the treatment of wounded soldiers. These units were powered using tubes of radium emanation, a colorless, radioactive gas given off by radium, later identified as radon. Skłodowska-Curie provided the tubes of radium, derived from the material she purified. Also, promptly after the war started, she donated the gold Nobel Prize medals she and her husband had been awarded, to the war effort.

Post-war years

In 1921, Skłodowska-Curie was welcomed triumphantly when she toured the United States to raise funds for research on radium. These distractions from her scientific labors and the attendant publicity, caused her much discomfort, but provided resources needed for her work. Her second American tour in 1929 succeeded in equipping the Warsaw Radium Institute, founded in 1925 with her sister, Bronisława, as director.
In her later years, Skłodowska-Curie headed the Pasteur Institute and a radioactivity laboratory created for her by the University of Paris.

The physical and societal aspects of the work of the Curies contributed substantially to shaping the world of the twentieth and twenty-first centuries. Cornell University professor L. Pearce Williams observes:

The result of the Curies’ work was epoch-making. Radium’s radioactivity was so great that it could not be ignored. It seemed to contradict the principle of theconservation of energy and therefore forced a reconsideration of the foundations of physics. On the experimental level the discovery of radium provided men likeErnest Rutherford with sources of radioactivity with which they could probe the structure of the atom. As a result of Rutherford’s experiments with alpha radiation, thenuclear atom was first postulated. In medicine, the radioactivity of radium appeared to offer a means by which cancer could be successfully attacked.^[23]

If the work of Maria Skłodowska–Curie helped overturn established ideas in physics and chemistry, it has had an equally profound effect in the societal sphere. In order to attain her scientific achievements, she had to overcome barriers that were placed in her way because she was a woman, in both her native and her adoptive country. This aspect of her life and career is highlighted in Françoise Giroud’s Marie Curie: A Life, which emphasizes Skłodowska’s role as a feministprecursor. She was ahead of her time, emancipated, independent, and in addition uncorrupted. Albert Einstein is reported to have remarked that she was probably the only person who was not corrupted by the fame that she had won.^[31]
Awards

Marie Skłodowska-Curie was the first woman to win a Nobel prize and the first person to win two Nobel Prizes.

• Nobel Prize in Physics (1903)
• Davy Medal (1903)
• Matteucci Medal (1904)
• Nobel Prize in Chemistry (1911)

The life of famous scientists may not be luxurious. The Curies reportedly used part of their award money to replace wallpaper in their Parisian home and install modern plumbing into a bathroom.^[32]
Honors

Madame Curie was decorated with the French Legion of Honor. In Poland, she had received honorary doctorates from the Lwów Polytechnic (1912), Poznań University (1922), Kraków’sJagiellonian University (1924), and the Warsaw Polytechnic (1926).
Their elder daughter, Irène Joliot-Curie, won a Nobel Prize for Chemistry in 1935 for discovering that aluminum could be made radioactive and emit neutrons when bombarded with alpha rays. Their younger daughter, Ève Curie, later wrote a biography of her mother.
In 1936, Michalina Mościcka, wife of Polish President Ignacy Mościcki, unveiled a statue of the Marie Curie in front of Warsaw’s Curie Institute, the former Radium Institute. Eight years later, the monument suffered damage from gunfire during the 1944 Warsaw Uprising. After the war, when maintenance work was being conducted, it was decided to leave these scars on the statue.^[14]
In 1967, a museum devoted to Skłodowska–Curie was established in Warsaw’s “New Town”, in her birthplace on ulica Freta (Freta Street).^[14]
Tributes

Panthéon, Paris

Polish banknote

As one of the most famous female scientists to date, Marie Curie has been an icon in the scientific world and has inspired many tributes and recognitions.
In 1995, she was the first woman laid to rest under the famous dome of the Paris Panthéon, alongside her husband, Pierre Curie.
The curie (symbol Ci), a unit of radioactivity, is named in honour of her and Pierre,^[33][34] as is the element with atomic number 96 — curium.
Three radioactive minerals are named after the Curies: curite, sklodowskite, and cuprosklodowskite.
Skłodowska-Curie’s likeness appeared on the Polish late-1980s inflationary 20,000-złoty banknote. Her likeness also has appeared on stamps and coins, as well as on the last French 500-franc note, before the franc was replaced by the euro.
Marie Curie was voted the “Most inspirational woman in science” in a 2022 poll carried out by New Scientist magazine on behalf of the L’Oreal UNESCO’For Women In Science’ programme. Curie received 25.1 per cent of all the votes cast, nearly twice as many as second-place Rosalind Franklin (14.2 per cent).^[35][36]
