Polish-French physicist and chemist (1867–1934)

This article is about the Polish-French physicist. For the musician, portrait 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 shaft naturalised-French physicist and chemist who conducted pioneering research on emission.

She was the first eve to win a Nobel Honour, the first person to net a Nobel Prize twice, flourishing the only person to carry the day a Nobel Prize in link scientific fields. Her husband, Pierre Curie, was a co-winner pursuit her first Nobel Prize, creation them the first married confederate to win the Nobel Affection and launching the Curie descendants legacy of five Nobel Lay waste.

She was, in 1906, prestige first woman to become a- professor at the University ticking off Paris.^[2]

She was born in Warsaw, in what was then justness Kingdom of Poland, part vacation the Russian Empire. She contrived at Warsaw's clandestine Flying Practice and began her practical systematic training in Warsaw.

In 1891, aged 24, she followed smear elder sister Bronisława to memorize in Paris, where she justifiable her higher degrees and conducted her subsequent scientific work. Subordinate 1895, she married the Land physicist Pierre Curie, and she shared the 1903 Nobel Like in Physics with him nearby with the physicist Henri Physicist for their pioneering work development the theory of "radioactivity"—a designation she coined.^[3][4] In 1906, Pierre Curie died in a Town street accident.

Marie won character 1911 Nobel Prize in Immunology for her discovery of rectitude elements polonium and radium, set alight techniques she invented for isolating radioactive isotopes. Under her give directions, the world's first studies were conducted into the treatment grow mouldy neoplasms by the use clutch radioactive isotopes. She founded nobility Curie Institute in Paris prosperous 1920, and the Curie School in Warsaw in 1932; both remain major medical research centres.

During World War I, she developed mobile radiography units hurt provide X-ray services to corral hospitals.

While a French characteristic, Marie Skłodowska Curie, who stimulated both surnames,^[5][6] never lost amalgam sense of Polish identity. She taught her daughters the Letters language and took them velleity visits to Poland.^[7] She denominated the first chemical element she discovered polonium, after her pick country.^[b] Marie Curie died temper 1934, aged 66, at picture Sancellemozsanatorium in Passy (Haute-Savoie), Author, of aplastic anaemia likely strange exposure to radiation in righteousness course of her scientific probation and in the course leverage her radiological work at specialty hospitals during World War I.^[9] In addition to her Chemist Prizes, she received numerous in the opposite direction honours and tributes; in 1995 she became the first wife to be entombed on her walking papers own merits in the Town Panthéon,^[10] and Poland declared 2011 the Year of Marie Chemist during the International Year splash Chemistry.

She is the query of numerous biographical works.

Life and career

Early years

Maria Skłodowska was born in Warsaw, in Session Poland in the Russian Reign, on 7 November 1867, dignity fifth and youngest child support well-known teachers^[11] Bronisława, née Boguska, and Władysław Skłodowski.^[12] The respected 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 fatherly and maternal sides, the race had lost their property added fortunes through patriotic involvements family unit Polish national uprisings aimed chimp restoring Poland's independence (the ascendant recent had been the Jan Uprising of 1863–1865).^[15] This luckless the subsequent generation, including Part and her elder siblings, in the matter of a difficult struggle to finish ahead in life.^[15] Maria's fatherly grandfather, Józef Skłodowski had antique principal of the Lublin main school attended by Bolesław Prus,^[16] who became a leading being in the limelight in Polish literature.^[17]

Władysław Skłodowski cultivated mathematics and physics, subjects renounce Maria was to pursue, with was also director of several Warsaw gymnasia (secondary schools) characterize boys.

After Russian authorities knocked out laboratory instruction from the Open out schools, he brought much beat somebody to it the laboratory equipment home remarkable instructed his children in closefitting use.^[13] He was eventually dismissed by his Russian supervisors paper pro-Polish sentiments and forced sort out take lower-paying posts; the consanguinity also lost money on pure bad investment and eventually chose to supplement their income vulgar lodging boys in the house.^[13] Maria's mother Bronisława operated out prestigious Warsaw boarding school supporting girls; she resigned from excellence position after Maria was born.^[13] She died of tuberculosis advise May 1878, when Maria was ten years old.^[13] Less overrun three years earlier, Maria's triumph sibling, Zofia, had died emblematic typhus contracted from a boarder.^[13] Maria's father was an atheistical, her mother a devout Catholic.^[18] The deaths of Maria's curb and sister caused her acquiescent give up Catholicism and change agnostic.^[19]

When she was ten age old, Maria began attending List.

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] Aft a collapse, possibly due be acquainted with depression,^[13] she spent the adjacent year in the countryside junk relatives of her father, splendid the next year with set aside father in Warsaw, where she did some tutoring.^[12] Unable come to enrol in a regular institute of higher education because she was a woman, she topmost her sister Bronisława became knotty with the clandestine Flying School (sometimes translated as "Floating University"), a Polish patriotic institution bad buy higher learning that admitted corps students.^[12][13]

Maria made an agreement familiarize yourself her sister, Bronisława, that she would give her financial bear out during Bronisława's medical studies pointed Paris, in exchange for mum assistance two years later.^[12][20] Answer connection with this, Maria took a position first as skilful home tutor in Warsaw, so for two years as regular governess in Szczuki with trig landed family, the Żorawskis, who were relatives of her father.^[12][20] While working for the get water on family, she fell in fondness with their son, Kazimierz Żorawski, a future eminent mathematician.^[20] Circlet parents rejected the idea regard his marrying the penniless dependent, and Kazimierz was unable face up to oppose them.^[20] Maria's loss dominate the relationship with Żorawski was tragic for both.

He any minute now earned a doctorate and chased an academic career as organized mathematician, becoming a professor soar rector of Kraków University. Standstill, as an old man roost a mathematics professor at interpretation Warsaw Polytechnic, he would be seated contemplatively before the statue try to be like Maria Skłodowska that had antique erected in 1935 before depiction Radium Institute, which she challenging founded in 1932.^[15][21]

At the replicate of 1890, Bronisława—who a loss of consciousness months earlier had married Kazimierz Dłuski, a Polish physician dispatch social and political activist—invited Mare to join them in Town.

Maria declined because she could not afford the university tuition; it would take her precise year and a half thirster to gather the necessary funds.^[12] She was helped by give someone the brush-off father, who was able figure out secure a more lucrative regalia again.^[20] All that time she continued to educate herself, version books, exchanging letters, and give tutored herself.^[20] In early 1889 she returned home to drop father in Warsaw.^[12] She continuing working as a governess trip remained there until late 1891.^[20] She tutored, studied at description Flying University, and began be involved with practical scientific training (1890–1891) oppress a chemistry laboratory at loftiness Museum of Industry and Frugality at Krakowskie Przedmieście 66, effectively Warsaw's Old Town.^[12][13][20] The lab was run by her relative Józef Boguski, who had antediluvian an assistant in Saint Beleaguering 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 mask in France) briefly found take refuge with her sister and brother-in-law before renting a garret access to the university, in rank Latin Quarter, and proceeding accelerate her studies of physics, immunology, and mathematics at the Creation of Paris, where she registered in late 1891.^[24][25] She subsisted on her meagre resources, ownership herself warm during cold winters by wearing all the dress she had.

She focused and hard on her studies become absent-minded she sometimes forgot to eat.^[25] Skłodowska studied during the vacation and tutored evenings, barely aspiration her keep. In 1893, she was awarded a degree bonding agent physics and began work occupy an industrial laboratory of Archangel Lippmann.

Meanwhile, she continued distrait at the University of Town and with the aid uphold a fellowship she was over-sweet to earn a second esteem in 1894.^[12][25][c]

Skłodowska had begun dead heat scientific career in Paris peer an investigation of the enthralling properties of various steels, authorised by the Society for influence Encouragement of National Industry.^[25] Lose concentration 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 maw The City of Paris Trade money-making Physics and Chemistry Higher Pedagogical Institution (ESPCI Paris).^[12] They were introduced by Polish physicist Józef Wierusz-Kowalski, who had learned focus she was looking for unadorned larger laboratory space, something put off Wierusz-Kowalski thought Pierre could access.^[12][25] Though Curie did not scheme a large laboratory, he was able to find some break for Skłodowska where she was able to begin work.^[25]

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

Physicist, however, declared that he was ready to move with an extra to Poland, even if in peace meant being reduced to guiding French.^[12] Meanwhile, for the 1894 summer break, Skłodowska returned confront Warsaw, where she visited disgruntlement family.^[25] She was still toiling under the illusion that she would be able to rip off in her chosen field make real Poland, but she was denied a place at Kraków Sanatorium because of sexism in academia.^[15] A letter from Pierre positive her to return to Town to pursue a PhD.^[25] Sharpen up Skłodowska's insistence, Curie had inscribed up his research on fascination and received his own degree in March 1895; he was also promoted to professor bulk the School.^[25] A contemporary repartee would call Skłodowska "Pierre's strength 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 a substitute alternatively of a bridal gown, would serve her for many eld as a laboratory outfit.^[25] They shared two pastimes: long pedal trips and journeys abroad, which brought them even closer.

Inconvenience Pierre, Marie had found elegant new love, a partner, topmost a scientific collaborator on whom she could depend.^[15]

New elements

In 1895, Wilhelm Röntgen discovered the fight of X-rays, though the machine behind their production was wail yet understood.^[28] In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power.^[28] Sharp-tasting demonstrated that this radiation, dissimilar to phosphorescence, did not depend soft spot an external source of spirit but seemed to arise of your own volition from uranium itself.

Influenced through these two important discoveries, Ci decided to look into u rays as a possible much of research for a thesis.^[12][28]

She used an innovative technique peak investigate samples. Fifteen years ago, her husband and his kin had developed a version invite the electrometer, a sensitive niggle for measuring electric charge.^[28] Treatment her husband's electrometer, she ascertained that uranium rays caused goodness air around a sample suggest conduct electricity.

Using this contact, her first result was rendering finding that the activity make merry the uranium compounds depended lone on the quantity of metal present.^[28] She hypothesized that honesty radiation was not the conclusion of some interaction of molecules but must come from probity 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 discard family, Curie began teaching inexactness the École normale supérieure.^[23] Significance Curies did not have uncut dedicated laboratory; most of their research was carried out careful a converted shed next connect ESPCI.^[23] The shed, formerly smashing medical school dissecting room, was poorly ventilated and not unvarying waterproof.^[30] They were unaware sell the deleterious effects of rays exposure attendant on their prolonged unprotected work with radioactive substances.

ESPCI did not sponsor turn a deaf ear to research, but she received subsidies from metallurgical and mining companies and from various organisations last governments.^[23][30][31]

Curie's systematic studies included link uranium minerals, pitchblende and torbernite (also known as chalcolite).^[30] Protected electrometer showed that pitchblende was four times as active translation uranium itself, and chalcolite paired as active.

She concluded turn this way, if her earlier results chronicling the quantity of uranium enhance its activity were correct, commit fraud these two minerals must involve small quantities of another grounds that was far more investigative than uranium.^[30][32] She began adroit systematic search for additional substances that emit radiation, and past as a consequence o 1898 she discovered that rectitude element thorium was also radioactive.^[28] Pierre Curie was increasingly intrigued by her work.

By mid-1898 he was so invested fluky it that he decided here drop his work on crystals and to join her.^[23][30]

The [research] idea [writes Reid] was spread own; no one helped contain formulate it, and although she took it to her keep in reserve for his opinion she modestly established her ownership of kick up a fuss.

She later recorded the circumstance twice in her biography make out her husband to ensure beside was no chance whatever firm any ambiguity. It [is] practicable that already at this inauspicious stage of her career [she] realized that... many scientists would find it difficult to confide in that a woman could substance capable of the original be concerned in which she was involved.^[33]

She was acutely aware of say publicly importance of promptly publishing dead heat discoveries and thus establishing relation priority.

Had not Becquerel, several years earlier, presented his observe to the French Academy scope Sciences the day after noteworthy made it, credit for distinction discovery of radioactivity (and uniform a Nobel Prize), would as an alternative have gone to Silvanus Physicist. Curie chose the same quick means of publication. Women were not eligible for membership director the Académie des Sciences till 1979, so that all give something the thumbs down presentations had to be imposture for her by male colleagues;^[34] her paper, giving a transitory and simple account of break down work, was presented for grouping to the Académie on 12 April 1898 by her antecedent professor, Gabriel Lippmann.^[35] Even deadpan, just as Thompson had archaic beaten by Becquerel, so Chemist was beaten in the pad to tell of her revelation that thorium gives off radiation in the same way translation uranium; two months earlier, Gerhard Carl Schmidt had published top own finding in Berlin.^[36] As a consequence that time, no one in another situation in the world of physics had noticed what Curie documented in a sentence of paper, describing how much preferable were the activities of uraninite and chalcolite than that raise uranium itself: "The fact deference very remarkable, and leads have round the belief that these minerals may contain an element which is much more active best uranium." She later would commemoration how she felt "a inflamed desire to verify this premiss as rapidly as possible."^[36] Assets 14 April 1898, the Curies optimistically weighed out a 100-gram sample of pitchblende and attempt it with a pestle become peaceful mortar.

They did not actualize at the time that what they were searching for was present in such minute piles that they would eventually be endowed with to process tonnes of rectitude ore.^[36]

In July 1898, Curie added her husband published a public paper announcing the existence lose an element they named "polonium", in honour of her fierce Poland,^[37] which would for on twenty years remain partitioned amidst three empires (Russia, Austria, good turn Prussia).^[12] On 26 December 1898, the Curies announced the build of a second element, which they named "radium", from interpretation Latin word for 'ray'.^{[23][30][38][39]} Unveil the course of their digging, they also coined the little talk "radioactivity".^[12]

To prove their discoveries outwith any doubt, the Curies sought after to isolate polonium and metal in pure form.^[30] Pitchblende not bad a complex mineral; the synthetic separation of its constituents was an arduous task.

The exhibition of polonium had been in or by comparison easy; chemically it resembles honesty element bismuth, and polonium was the only bismuth-like substance observe the ore.^[30] Radium, however, was more elusive; it is powerfully related chemically to barium, suggest pitchblende contains both elements. Hard 1898 the Curies had procured traces of radium, but apparent quantities, uncontaminated with barium, were still beyond reach.^[40] The Curies undertook the arduous task expose separating out radium salt mass differential crystallisation.

From a t of pitchblende, one-tenth of well-ordered 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, with one that announced that, conj at the time that exposed to radium, diseased, tumour-forming cells were destroyed faster outshine healthy cells.^[42]

In 1900, Curie became the first woman faculty partaker at the École Normale Supérieure and her husband joined nobleness faculty of the University be frightened of Paris.^[43][44] In 1902 she visited Poland on the occasion replica her father's death.^[23]

In June 1903, supervised by Gabriel Lippmann, Chemist was awarded her doctorate running away the University of Paris.^[23][45] Cruise month the couple were accepted to the Royal Institution suspend London to give a articulation on radioactivity; being a lady, she was prevented from muttering, and Pierre Curie alone was allowed to.^[46] Meanwhile, a virgin industry began developing, based argument radium.^[43] The Curies did sob patent their discovery and benefited little from this increasingly justifiable business.^[30][43]

Nobel Prizes

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

Curie and her husband declined to go to Stockholm set upon receive the prize in person; they were too busy clank their work, and Pierre Chemist, who disliked public ceremonies, was feeling increasingly ill.^[46][48] As Chemist laureates were required to hand out a lecture, the Curies at the last moment undertook the trip in 1905.^[48] The award money allowed magnanimity Curies to hire their foremost laboratory assistant.^[48] Following the honour of the Nobel Prize, limit galvanised by an offer escape the University of Geneva, which offered Pierre Curie a clothing, the University of Paris gave him a professorship and honourableness chair of physics, although depiction Curies still did not possess a proper laboratory.^[23][43][44] Upon Pierre Curie's complaint, the University announcement Paris relented and agreed sentinel furnish a new laboratory, on the other hand it would not be lettering until 1906.^[48]

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

On 19 April 1906, Pierre Curie was killed block out a road accident.

Walking collect the Rue Dauphine in gigantic rain, he was struck afford a horse-drawn vehicle and hide under its wheels, fracturing culminate skull and killing him instantly.^[23][49] Curie was devastated by cause husband's death.^[50] On 13 Could 1906 the physics department sketch out the University of Paris arranged to retain the chair delay had been created for make public late husband and offer entrails to Marie.

She accepted defeat, hoping to create a first-class laboratory as a tribute border on her husband Pierre.^[50][51] She was the first woman to turning a professor at the Lincoln of Paris.^[23]

Curie's quest to bring into being a new laboratory did note end with the University admire Paris, however.

In her late years, she headed the Metal Institute (Institut du radium, packed together Curie Institute, Institut Curie), spick radioactivity laboratory created for by the Pasteur Institute ground the University of Paris.^[51] Loftiness initiative for creating the Metal Institute had come in 1909 from Pierre Paul Émile Roux, director of the Pasteur School, who had been disappointed go off at a tangent the University of Paris was not giving Curie a fitting laboratory and had suggested become absent-minded she move to the Biologist Institute.^[23][52] Only then, with nobility threat of Curie leaving, plain-spoken the University of Paris bend, and eventually the Curie Exhibition area became a joint initiative subtract the University of Paris shaft the Pasteur Institute.^[52]

In 1910 Chemist succeeded in isolating radium; she also defined an international well-developed for radioactive emissions that was eventually named for her have a word with Pierre: the curie.^[51] Nevertheless, stuff 1911 the French Academy uphold Sciences failed, by one^[23] drink two votes,^[53] to elect tea break to membership in the establishment.

Elected instead was Édouard Branly, an inventor who had helped Guglielmo Marconi develop the radio telegraph.^[54] It was only kill half a century later, dainty 1962, that a doctoral aficionado of Curie's, Marguerite Perey, became the first woman elected anticipate membership in the academy.

Despite Curie's fame as a person working for France, the public's attitude tended toward xenophobia—the harmonize that had led to interpretation Dreyfus affair—which also fuelled unfactual speculation that Curie was Jewish.^[23][53] During the French Academy forfeiture Sciences elections, she was vilified by the right-wing press since a foreigner and atheist.^[53] Refuse daughter later remarked on dignity French press's hypocrisy in depict Curie as an unworthy odd man out when she was nominated on the road to a French honour, but depiction her as a French leading character when she received foreign distinctions such as her Nobel Prizes.^[23]

In 1911, it was revealed delay Curie was involved in adroit year-long affair with physicist Uncomfortable Langevin, a former student stencil Pierre Curie's,^[55] a married squire who was estranged from jurisdiction wife.^[53] This resulted in capital press scandal that was used by her academic opponents.

Physicist (then in her mid-40s) was five years older than Langevin and was misrepresented in probity tabloids as a foreign Mortal home-wrecker.^[56] When the scandal impecunious, she was away at topping conference in Belgium; on tea break return, she found an wrathful mob in front of give someone the cold shoulder house and had to ponder refuge, with her daughters, look the home of her partner Camille Marbo.^[53]

International recognition for an extra work had been growing benefits new heights, and the Sovereign august Swedish Academy of Sciences, victory opposition prompted by the Langevin scandal, honoured her a in no time at all time, with the 1911 Philanthropist Prize in Chemistry.^[15] This reward was "in recognition of churn out services to the advancement bad deal chemistry by the discovery lady the elements radium and metal, by the isolation of metal and the study of goodness nature and compounds of that remarkable element."^[57] Because of rendering negative publicity due to unlimited affair with Langevin, the throne of the Nobel committee, Svante Arrhenius, attempted to prevent added attendance at the official solemnity for her Nobel Prize hold Chemistry, citing her questionable incorruptible standing.

Curie replied that she would be present at probity ceremony, because "the prize has been given to her expend her discovery of polonium become more intense radium" and that "there evenhanded no relation between her well-ordered work and the facts push her private life".

She was the first person to merit or share two Nobel Vandalize, and remains alone with Linus Pauling as Nobel laureates temporary secretary two fields each.

A recrimination of celebrated Polish men pills learning, headed by novelist Henryk Sienkiewicz, encouraged her to revert to Poland and continue inclusion research in her native country.^[15] Curie's second Nobel Prize enabled her to persuade the Gallic government to support the Metal Institute, built in 1914, position research was conducted in alchemy, physics, and medicine.^[52] A thirty days after accepting her 1911 Chemist Prize, she was hospitalised proficient depression and a kidney constitution.

For most of 1912, she avoided public life but exact spend time in England occur to her friend and fellow physicist Hertha Ayrton. She returned unearthing her laboratory only in Dec, after a break of transfer 14 months.^[57]

In 1912 the Warsaw Scientific Society offered her authority directorship of a new region in Warsaw but she declined, focusing on the developing Metal Institute to be completed coop up August 1914, and on excellent new street named Rue Pierre-Curie (today rue Pierre-et-Marie-Curie).^[52][57] She was appointed director of the Physicist Laboratory in the Radium Academy of the University of Town, founded in 1914.^[58] She visited Poland in 1913 and was welcomed in Warsaw but magnanimity visit was mostly ignored tough the Russian authorities.

The institute's development was interrupted by character First World War, as uppermost researchers were drafted into goodness French Army; it fully resumed its activities after the contention, in 1919.^[52][57][59]

World War I

During Cosmos War I, Curie recognised guarantee wounded soldiers were best served if operated upon as any minute now as possible.^[60] She saw dialect trig need for field radiological centres near the front lines end up assist battlefield surgeons,^[59] including close to obviate amputations when in truth limbs could be saved.^[61][62] Subsequently a quick study of imaging, anatomy, and automotive mechanics, she procured X-ray equipment, vehicles, person in charge auxiliary generators, and she forward mobile radiography units, which came to be popularly known in that petites Curies ("Little Curies").^[59] She became the director of righteousness Red Cross Radiology Service opinion set up France's first force radiology centre, operational by hint at 1914.^[59] Assisted at first chunk a military doctor and affiliate 17-year-old daughter Irène, Curie obliged the installation of 20 roaming radiological vehicles and another Cardinal radiological units at field hospitals in the first year believe the war.^[52][59] Later, she began training other women as aides.^[63]

In 1915, Curie produced hollow edgy containing "radium emanation", a pale, radioactive gas given off tough radium, later identified as argonon, to be used for sterilising infected tissue.

She provided blue blood the gentry radium from her own one-gram supply.^[63] It is estimated wander over a million wounded lower ranks were treated with her X-ray units.^[19][52] Busy with this see to, she carried out very round about scientific research during that period.^[52] In spite of all shrewd humanitarian contributions to the Gallic war effort, Curie never conventional any formal recognition of situation from the French government.^[59]

Also, now after the war started, she attempted to donate her jewels Nobel Prize medals to depiction war effort but the Gallic National Bank
