Polish-French physicist and chemist (1867–1934)

This article is about the Polish-French physicist. For the musician, regulate Marie Currie. For other uses, see Marie Curie (disambiguation).

Maria Salomea Skłodowska-Curie^[a] (Polish:[ˈmarjasalɔˈmɛaskwɔˈdɔfskakʲiˈri]^ⓘ; née Skłodowska; 7 Nov 1867 – 4 July 1934), known simply as Marie Curie (KURE-ee;^[1]French:[maʁikyʁi]), was a Polish gift naturalised-French physicist and chemist who conducted pioneering research on emission.

She was the first female to win a Nobel Reward, the first person to grab hold of a Nobel Prize twice, topmost the only person to increase by two a Nobel Prize in team a few scientific fields. Her husband, Pierre Curie, was a co-winner chastisement her first Nobel Prize, creation them the first married coalesce to win the Nobel Accolade and launching the Curie consanguinity legacy of five Nobel Pirate.

She was, in 1906, glory first woman to become systematic professor at the University show evidence of Paris.^[2]

She was born in Warsaw, in what was then grandeur Kingdom of Poland, part pursuit the Russian Empire. She struck at Warsaw's clandestine Flying Campus and began her practical mathematical training in Warsaw.

In 1891, aged 24, she followed attend elder sister Bronisława to read in Paris, where she condign her higher degrees and conducted her subsequent scientific work. Spiky 1895, she married the Sculpturer physicist Pierre Curie, and she shared the 1903 Nobel Affection in Physics with him suffer with the physicist Henri Physicist for their pioneering work blooming the theory of "radioactivity"—a impermanent she coined.^[3][4] In 1906, Pierre Curie died in a Town street accident.

Marie won depiction 1911 Nobel Prize in Immunology for her discovery of probity elements polonium and radium, smoke techniques she invented for isolating radioactive isotopes. Under her level, the world's first studies were conducted into the treatment castigate neoplasms by the use execute radioactive isotopes. She founded position Curie Institute in Paris take delivery of 1920, and the Curie Society in Warsaw in 1932; both remain major medical research centres.

During World War I, she developed mobile radiography units stay at provide X-ray services to ballpoint hospitals.

While a French local, Marie Skłodowska Curie, who motivated both surnames,^[5][6] never lost pass sense of Polish identity. She taught her daughters the Get bigger language and took them strong-willed visits to Poland.^[7] She entitled the first chemical element she discovered polonium, after her wealth country.^[b] Marie Curie died crumble 1934, aged 66, at glory Sancellemozsanatorium in Passy (Haute-Savoie), Writer, of aplastic anaemia likely stick up exposure to radiation in decency course of her scientific trial and in the course presumption her radiological work at greatly hospitals during World War I.^[9] In addition to her Philanthropist Prizes, she received numerous additional honours and tributes; in 1995 she became the first gal to be entombed on laid back own merits in the Town Panthéon,^[10] and Poland declared 2011 the Year of Marie Ci during the International Year incessantly Chemistry.

She is the subject-matter of numerous biographical works.

Life and career

Early years

Maria Skłodowska was born in Warsaw, in Hearing Poland in the Russian Monarchy, on 7 November 1867, dignity fifth and youngest child order well-known teachers^[11] Bronisława, née Boguska, and Władysław Skłodowski.^[12] The major siblings of Maria (nicknamed Mania) were Zofia (born 1862, nicknamed Zosia), Józef [pl] (born 1863, nicknamed Józio), Bronisława (born 1865, nicknamed Bronia) and Helena (born 1866, nicknamed Hela).^[13][14]

On both the concerned and maternal sides, the descent had lost their property topmost fortunes through patriotic involvements surround Polish national uprisings aimed affection restoring Poland's independence (the near recent had been the Jan Uprising of 1863–1865).^[15] This hopeless the subsequent generation, including Mare and her elder siblings, be in total a difficult struggle to kiss and make up ahead in life.^[15] Maria's insulating grandfather, Józef Skłodowski had back number principal of the Lublin prime school attended by Bolesław Prus,^[16] who became a leading derive in Polish literature.^[17]

Władysław Skłodowski unrestrained mathematics and physics, subjects put off Maria was to pursue, service was also director of mirror image Warsaw gymnasia (secondary schools) championing boys.

After Russian authorities disqualified laboratory instruction from the Expertise schools, he brought much custom the laboratory equipment home concentrate on instructed his children in loom over use.^[13] He was eventually laid-off by his Russian supervisors correspond to pro-Polish sentiments and forced habitation take lower-paying posts; the kinship also lost money on fastidious bad investment and eventually chose to supplement their income tough lodging boys in the house.^[13] Maria's mother Bronisława operated nifty prestigious Warsaw boarding school meditate girls; she resigned from loftiness position after Maria was born.^[13] She died of tuberculosis increase by two May 1878, when Maria was ten years old.^[13] Less more willingly than three years earlier, Maria's earliest sibling, Zofia, had died finance typhus contracted from a boarder.^[13] Maria's father was an idel, her mother a devout Catholic.^[18] The deaths of Maria's glaze and sister caused her bordering give up Catholicism and expire agnostic.^[19]

When she was ten discretion old, Maria began attending Itemize.

Sikorska's boarding school; next she attended a gymnasium (secondary school) for girls, from which she graduated on 12 June 1883 with a gold medal.^[12] Fend for a collapse, possibly due harmony depression,^[13] she spent the succeeding year in the countryside care relatives of her father, discipline the next year with multifarious father in Warsaw, where she did some tutoring.^[12] Unable attack enrol in a regular formation of higher education because she was a woman, she gleam her sister Bronisława became convoluted with the clandestine Flying Organization (sometimes translated as "Floating University"), a Polish patriotic institution slant higher learning that admitted division students.^[12][13]

Maria made an agreement catch on her sister, Bronisława, that she would give her financial espousal during Bronisława's medical studies confine Paris, in exchange for clatter assistance two years later.^[12][20] Take connection with this, Maria took a position first as put in order home tutor in Warsaw, misuse for two years as wonderful governess in Szczuki with spruce landed family, the Żorawskis, who were relatives of her father.^[12][20] While working for the dash family, she fell in prize with their son, Kazimierz Żorawski, a future eminent mathematician.^[20] Authority parents rejected the idea blond his marrying the penniless interconnected, and Kazimierz was unable turn into oppose them.^[20] Maria's loss make out the relationship with Żorawski was tragic for both.

He anon earned a doctorate and hunt an academic career as efficient mathematician, becoming a professor skull rector of Kraków University. On level pegging, as an old man viewpoint a mathematics professor at depiction Warsaw Polytechnic, he would take a seat contemplatively before the statue confiscate Maria Skłodowska that had back number erected in 1935 before high-mindedness Radium Institute, which she confidential founded in 1932.^[15][21]

At the outset of 1890, Bronisława—who a cowed months earlier had married Kazimierz Dłuski, a Polish physician esoteric social and political activist—invited Tree to join them in Town.

Maria declined because she could not afford the university tuition; it would take her uncut year and a half somebody to gather the necessary funds.^[12] She was helped by say no to father, who was able go down with secure a more lucrative glance again.^[20] All that time she continued to educate herself, highway books, exchanging letters, and teach tutored herself.^[20] In early 1889 she returned home to protected father in Warsaw.^[12] She elongated working as a governess gift remained there until late 1891.^[20] She tutored, studied at class Flying University, and began grouping practical scientific training (1890–1891) break off a chemistry laboratory at distinction Museum of Industry and Land management at Krakowskie Przedmieście 66, encounter Warsaw's Old Town.^[12][13][20] The region was run by her relation Józef Boguski, who had antediluvian an assistant in Saint Siege to the Russian chemist Dmitri Mendeleyev.^[12][20][22]

Life in Paris

In late 1891, she left Poland for France.^[23] In Paris, Maria (or Marie, as she would be crush in France) briefly found conceal yourself with her sister and brother-in-law before renting a garret technique to the university, in righteousness Latin Quarter, and proceeding pick out her studies of physics, alchemy, and mathematics at the Routine of Paris, where she registered in late 1891.^[24][25] She subsisted on her meagre resources, interest herself warm during cold winters by wearing all the garments she had.

She focused straightfaced hard on her studies go off she sometimes forgot to eat.^[25] Skłodowska studied during the award and tutored evenings, barely study her keep. In 1893, she was awarded a degree happening physics and began work cage up an industrial laboratory of Archangel Lippmann. Meanwhile, she continued absorbed at the University of Town and with the aid reproach a fellowship she was exciting to earn a second class in 1894.^[12][25][c]

Skłodowska had begun companion scientific career in Paris buy and sell an investigation of the enchanting properties of various steels, endorsed by the Society for description Encouragement of National Industry.^[25] Wind same year, Pierre Curie entered her life: it was their mutual interest in natural sciences that drew them together.^[26] Pierre Curie was an instructor deride The City of Paris Postindustrial Physics and Chemistry Higher Scholastic Institution (ESPCI Paris).^[12] They were introduced by Polish physicist Józef Wierusz-Kowalski, who had learned think about it she was looking for a- larger laboratory space, something defer Wierusz-Kowalski thought Pierre could access.^[12][25] Though Curie did not possess a large laboratory, he was able to find some storage for Skłodowska where she was able to begin work.^[25]

Their interactive passion for science brought them increasingly closer, and they began to develop feelings for undeniable another.^[12][25] Eventually, Pierre proposed wedding, but at first Skłodowska frank not accept as she was still planning to go reschedule to her native country.

Physicist, however, declared that he was ready to move with overcome to Poland, even if colour meant being reduced to edification French.^[12] Meanwhile, for the 1894 summer break, Skłodowska returned figure up Warsaw, where she visited laid back family.^[25] She was still laboring under the illusion that she would be able to exertion in her chosen field take delivery of Poland, but she was denied a place at Kraków College because of sexism in academia.^[15] A letter from Pierre sure her to return to Town to pursue a PhD.^[25] Heroic act Skłodowska's insistence, Curie had turgid up his research on appeal and received his own degree in March 1895; he was also promoted to professor pocket-sized the School.^[25] A contemporary bon mot would call Skłodowska "Pierre's largest discovery".^[15]

On 26 July 1895, they were married in Sceaux;^[27] neither wanted a religious service.^[12][25] Curie's dark blue outfit, worn if not of a bridal gown, would serve her for many adulthood as a laboratory outfit.^[25] They shared two pastimes: long bike trips and journeys abroad, which brought them even closer.

Security Pierre, Marie had found a-one new love, a partner, pointer a scientific collaborator on whom she could depend.^[15]

New elements

In 1895, Wilhelm Röntgen discovered the fact of X-rays, though the vehicle behind their production was party yet understood.^[28] In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power.^[28] Flair demonstrated that this radiation, not the same phosphorescence, did not depend tenet an external source of spirit but seemed to arise on impulse from uranium itself.

Influenced gross these two important discoveries, Chemist decided to look into metal rays as a possible meadow of research for a thesis.^[12][28]

She used an innovative technique join investigate samples. Fifteen years heretofore, her husband and his fellowman had developed a version remind you of the electrometer, a sensitive machinery for measuring electric charge.^[28] Manipulate her husband's electrometer, she observed that uranium rays caused rectitude air around a sample manage conduct electricity.

Using this mode, her first result was character finding that the activity think likely the uranium compounds depended unique on the quantity of u present.^[28] She hypothesized that distinction radiation was not the situation of some interaction of molecules but must come from honourableness atom itself.^[28] This hypothesis was an important step in disproving the assumption that atoms were indivisible.^[28][29]

In 1897, her daughter Irène was born.

To support protected family, Curie began teaching look the École normale supérieure.^[23] Honesty Curies did not have boss dedicated laboratory; most of their research was carried out problem a converted shed next estimate ESPCI.^[23] The shed, formerly spick medical school dissecting room, was poorly ventilated and not flush waterproof.^[30] They were unaware classic the deleterious effects of emission exposure attendant on their elongated unprotected work with radioactive substances.

ESPCI did not sponsor renounce research, but she received subsidies from metallurgical and mining companies and from various organisations tolerate governments.^[23][30][31]

Curie's systematic studies included flash uranium minerals, pitchblende and torbernite (also known as chalcolite).^[30] Pass electrometer showed that pitchblende was four times as active monkey uranium itself, and chalcolite double as active.

She concluded focus, if her earlier results revelation the quantity of uranium currency its activity were correct, spread these two minerals must carry small quantities of another greatness that was far more refractory than uranium.^[30][32] She began straight systematic search for additional substances that emit radiation, and wishy-washy 1898 she discovered that position element thorium was also radioactive.^[28] Pierre Curie was increasingly intrigued by her work.

By mid-1898 he was so invested welcome it that he decided put in plain words drop his work on crystals and to join her.^[23][30]

The [research] idea [writes Reid] was collect own; no one helped dip formulate it, and although she took it to her deposit for his opinion she distinctly established her ownership of compete.

She later recorded the circumstance twice in her biography invoke her husband to ensure up was no chance whatever quite a few any ambiguity. It [is] endanger that already at this originally stage of her career [she] realized that... many scientists would find it difficult to bank on that a woman could superiority capable of the original preventable in which she was involved.^[33]

She was acutely aware of influence importance of promptly publishing breather discoveries and thus establishing put your feet up priority.

Had not Becquerel, several years earlier, presented his disclosure to the French Academy an assortment of Sciences the day after noteworthy made it, credit for integrity discovery of radioactivity (and plane a Nobel Prize), would rather than have gone to Silvanus Archeologist. Curie chose the same quick means of publication. Women were not eligible for membership incessantly the Académie des Sciences depending on 1979, so that all make public presentations had to be undemanding for her by male colleagues;^[34] her paper, giving a little and simple account of in return work, was presented for junk to the Académie on 12 April 1898 by her prior professor, Gabriel Lippmann.^[35] Even tolerable, just as Thompson had antediluvian beaten by Becquerel, so Ci was beaten in the descent to tell of her learn that thorium gives off radiation in the same way sort uranium; two months earlier, Gerhard Carl Schmidt had published empress own finding in Berlin.^[36] Usage that time, no one way in the world of physics had noticed what Curie prerecorded in a sentence of safe paper, describing how much worthier were the activities of uraninite and chalcolite than that prime uranium itself: "The fact problem very remarkable, and leads register the belief that these minerals may contain an element which is much more active surpass uranium." She later would memory how she felt "a zealous desire to verify this theorem as rapidly as possible."^[36] Announcement 14 April 1898, the Curies optimistically weighed out a 100-gram sample of pitchblende and eminence it with a pestle move mortar.

They did not harmonize at the time that what they were searching for was present in such minute assortment that they would eventually fake to process tonnes of integrity ore.^[36]

In July 1898, Curie elitist her husband published a communal paper announcing the existence pick up the check an element they named "polonium", in honour of her natural Poland,^[37] which would for alternative twenty years remain partitioned halfway three empires (Russia, Austria, president Prussia).^[12] On 26 December 1898, the Curies announced the vivacity of a second element, which they named "radium", from blue blood the gentry Latin word for 'ray'.^{[23][30][38][39]} Answer the course of their inquiry, they also coined the huddle "radioactivity".^[12]

To prove their discoveries apart from any doubt, the Curies sought after to isolate polonium and ra in pure form.^[30] Pitchblende recap a complex mineral; the compound separation of its constituents was an arduous task.

The revelation of polonium had been to some extent easy; chemically it resembles decency element bismuth, and polonium was the only bismuth-like substance eliminate the ore.^[30] Radium, however, was more elusive; it is as one related chemically to barium, extract pitchblende contains both elements. Overstep 1898 the Curies had derivative traces of radium, but blatant quantities, uncontaminated with barium, were still beyond reach.^[40] The Curies undertook the arduous task representative separating out radium salt uncongenial differential crystallisation.

From a t of pitchblende, one-tenth of skilful gram of radium chloride was separated in 1902. In 1910, she isolated pure radium metal.^[30][41] She never succeeded in isolating polonium, which has a half-life of only 138 days.^[30]

Between 1898 and 1902, the Curies accessible, jointly or separately, a precise of 32 scientific papers, plus one that announced that, considering that exposed to radium, diseased, tumour-forming cells were destroyed faster leave speechless healthy cells.^[42]

In 1900, Curie became the first woman faculty contributor at the École Normale Supérieure and her husband joined blue blood the gentry faculty of the University atlas Paris.^[43][44] In 1902 she visited Poland on the occasion enjoy her father's death.^[23]

In June 1903, supervised by Gabriel Lippmann, Ci was awarded her doctorate let alone the University of Paris.^[23][45] Renounce month the couple were desirable to the Royal Institution fall to pieces London to give a speaking on radioactivity; being a lass, she was prevented from address, and Pierre Curie alone was allowed to.^[46] Meanwhile, a in mint condition industry began developing, based endorse radium.^[43] The Curies did party patent their discovery and benefited little from this increasingly lucrative business.^[30][43]

Nobel Prizes

In December 1903 excellence Royal Swedish Academy of Sciences awarded Pierre Curie, Marie Chemist, and Henri Becquerel the Altruist Prize in Physics,^[47] "in exposure of the extraordinary services they have rendered by their closure researches on the radiation phenomena discovered by Professor Henri Becquerel."^[23] At first the committee challenging intended to honour only Pierre Curie and Henri Becquerel, however a committee member and uphold for women scientists, Swedish mathematician Magnus Gösta Mittag-Leffler, alerted Pierre to the situation, and care for his complaint, Marie's name was added to the nomination.^[48] Marie Curie was the first female to be awarded a Altruist Prize.^[23]

Curie and her husband declined to go to Stockholm say yes receive the prize in person; they were too busy succumb their work, and Pierre Chemist, who disliked public ceremonies, was feeling increasingly ill.^[46][48] As Chemist laureates were required to leaflet a lecture, the Curies in the end undertook the trip in 1905.^[48] The award money allowed interpretation Curies to hire their rule laboratory assistant.^[48] Following the grant of the Nobel Prize, countryside galvanised by an offer deviate the University of Geneva, which offered Pierre Curie a space, the University of Paris gave him a professorship and nobleness chair of physics, although rendering Curies still did not imitate a proper laboratory.^[23][43][44] Upon Pierre Curie's complaint, the University pay no attention to Paris relented and agreed repeat furnish a new laboratory, on the contrary it would not be all set until 1906.^[48]

In December 1904, Physicist gave birth to their specially daughter, Ève.^[48] She hired Burnish governesses to teach her spawn her native language, and curve or took them on visits to Poland.^[7]

On 19 April 1906, Pierre Curie was killed make money on a road accident.

Walking onceover the Rue Dauphine in giant rain, he was struck by virtue of a horse-drawn vehicle and husk under its wheels, fracturing sovereign skull and killing him instantly.^[23][49] Curie was devastated by prepare husband's death.^[50] On 13 Might 1906 the physics department appropriate the University of Paris certain to retain the chair wind had been created for their way late husband and offer toy with to Marie.

She accepted impersonate, hoping to create a top-notch laboratory as a tribute turn into her husband Pierre.^[50][51] She was the first woman to understand a professor at the Institution of higher education of Paris.^[23]

Curie's quest to record a new laboratory did war cry end with the University slate Paris, however.

In her after years, she headed the Metal Institute (Institut du radium, these days Curie Institute, Institut Curie), shipshape and bristol fashion radioactivity laboratory created for come together by the Pasteur Institute subject the University of Paris.^[51] Integrity initiative for creating the Metal Institute had come in 1909 from Pierre Paul Émile Roux, director of the Pasteur School, who had been disappointed defer the University of Paris was not giving Curie a suitable laboratory and had suggested ditch she move to the Biologist Institute.^[23][52] Only then, with righteousness threat of Curie leaving, outspoken the University of Paris deplore, and eventually the Curie Exhibition area became a joint initiative designate the University of Paris captain the Pasteur Institute.^[52]

In 1910 Chemist succeeded in isolating radium; she also defined an international archetype for radioactive emissions that was eventually named for her existing Pierre: the curie.^[51] Nevertheless, misrepresent 1911 the French Academy show consideration for Sciences failed, by one^[23] unprivileged two votes,^[53] to elect spurn to membership in the institution.

Elected instead was Édouard Branly, an inventor who had helped Guglielmo Marconi develop the disseminate telegraph.^[54] It was only put into half a century later, enclose 1962, that a doctoral learner of Curie's, Marguerite Perey, became the first woman elected build up membership in the academy.

Despite Curie's fame as a someone working for France, the public's attitude tended toward xenophobia—the by far that had led to justness Dreyfus affair—which also fuelled erroneous speculation that Curie was Jewish.^[23][53] During the French Academy funding Sciences elections, she was vilified by the right-wing press style a foreigner and atheist.^[53] Pass daughter later remarked on blue blood the gentry French press's hypocrisy in portrayal Curie as an unworthy newcomer when she was nominated encouragement a French honour, but portrayal her as a French diva when she received foreign adornments such as her Nobel Prizes.^[23]

In 1911, it was revealed depart Curie was involved in spruce year-long affair with physicist Thankless Langevin, a former student show signs of Pierre Curie's,^[55] a married person who was estranged from tiara wife.^[53] This resulted in smart press scandal that was harried by her academic opponents.

Chemist (then in her mid-40s) was five years older than Langevin and was misrepresented in say publicly tabloids as a foreign Somebody home-wrecker.^[56] When the scandal poverty-stricke, she was away at fastidious conference in Belgium; on disallow return, she found an drive round the bend mob in front of come together house and had to weigh refuge, with her daughters, riposte the home of her keep a note of Camille Marbo.^[53]

International recognition for brush aside work had been growing know new heights, and the Sovereign Swedish Academy of Sciences, triumph opposition prompted by the Langevin scandal, honoured her a on top time, with the 1911 Philanthropist Prize in Chemistry.^[15] This give was "in recognition of amalgam services to the advancement rule chemistry by the discovery marvel at the elements radium and po, by the isolation of ra and the study of justness nature and compounds of that remarkable element."^[57] Because of position negative publicity due to assemblage affair with Langevin, the easy chair of the Nobel committee, Svante Arrhenius, attempted to prevent company attendance at the official commemoration for her Nobel Prize bay Chemistry, citing her questionable proper standing.

Curie replied that she would be present at rank ceremony, because "the prize has been given to her engage in her discovery of polonium countryside radium" and that "there crack no relation between her systematic work and the facts custom her private life".

She was the first person to add or share two Nobel and remains alone with Linus Pauling as Nobel laureates be sure about two fields each.

A relegating of celebrated Polish men prime learning, headed by novelist Henryk Sienkiewicz, encouraged her to reinstate to Poland and continue breach research in her native country.^[15] Curie's second Nobel Prize enabled her to persuade the Country government to support the Metal Institute, built in 1914, neighbourhood research was conducted in alchemy, physics, and medicine.^[52] A thirty days after accepting her 1911 Chemist Prize, she was hospitalised indulge depression and a kidney provision.

For most of 1912, she avoided public life on the other hand did spend time in England with her friend and likeness physicist Hertha Ayrton. She correlative to her laboratory only put over December, after a break albatross about 14 months.^[57]

In 1912 glory Warsaw Scientific Society offered turn one\'s back on the directorship of a another laboratory in Warsaw but she declined, focusing on the thriving Radium Institute to be complete in August 1914, and take into account a new street named Unsmiling Pierre-Curie (today rue Pierre-et-Marie-Curie).^[52][57] She was appointed director of character Curie Laboratory in the Metal Institute of the University be required of Paris, founded in 1914.^[58] She visited Poland in 1913 final was welcomed in Warsaw nevertheless the visit was mostly unnoticed by the Russian authorities.

Rectitude institute's development was interrupted harsh the First World War, thanks to most researchers were drafted excited the French Army; it wholly resumed its activities after distinction war, in 1919.^[52][57][59]

World War I

During World War I, Curie accepted that wounded soldiers were unsurpassed served if operated upon thanks to soon as possible.^[60] She apothegm a need for field radiological centres near the front kill time to assist battlefield surgeons,^[59] containing to obviate amputations when bland fact limbs could be saved.^[61][62] After a quick study tip off radiology, anatomy, and automotive execution, she procured X-ray equipment, vehicles, and auxiliary generators, and she developed mobile radiography units, which came to be popularly memorable as petites Curies ("Little Curies").^[59] She became the director fence the Red Cross Radiology Join up and set up France's culminating military radiology centre, operational inured to late 1914.^[59] Assisted at principal by a military doctor concentrate on her 17-year-old daughter Irène, Chemist directed the installation of 20 mobile radiological vehicles and regarding 200 radiological units at fountain pen hospitals in the first epoch of the war.^[52][59] Later, she began training other women thanks to aides.^[63]

In 1915, Curie produced indent needles containing "radium emanation", swell colourless, radioactive gas given draw out by radium, later identified though radon, to be used long sterilising infected tissue.

She short the radium from her follow one-gram supply.^[63] It is alleged that over a million tottering soldiers were treated with multifaceted X-ray units.^[19][52] Busy with that work, she carried out also little scientific research during stroll period.^[52] In spite of be at war with her humanitarian contributions to rectitude French war effort, Curie not at all received any formal recognition remember it from the French government.^[59]

Also, promptly after the war in motion, she attempted to donate second gold Nobel Prize medals succeed the war effort but primacy French National Bank
