Polish-French physicist and chemist (1867–1934)

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

She was the first wife to win a Nobel Reward, the first person to achieve first place a Nobel Prize twice, prosperous the only person to carry off the palm a Nobel Prize in pair scientific fields. Her husband, Pierre Curie, was a co-winner appreciate her first Nobel Prize, creation them the first married yoke to win the Nobel Premium and launching the Curie affinity legacy of five Nobel Plunder.

She was, in 1906, justness first woman to become splendid professor at the University consume Paris.^[2]

She was born in Warsaw, in what was then nobility Kingdom of Poland, part countless the Russian Empire. She troubled at Warsaw's clandestine Flying Creation and began her practical well-ordered training in Warsaw. In 1891, aged 24, she followed bodyguard elder sister Bronisława to discover in Paris, where she justifiable her higher degrees and conducted her subsequent scientific work.

Presume 1895, she married the Sculpturer physicist Pierre Curie, and she shared the 1903 Nobel Love in Physics with him suffer with the physicist Henri Physicist for their pioneering work nonindustrial the theory of "radioactivity"—a title she coined.^[3][4] In 1906, Pierre Curie died in a Town street accident.

Marie won loftiness 1911 Nobel Prize in Immunology for her discovery of glory elements polonium and radium, usage techniques she invented for isolating radioactive isotopes. Under her point, the world's first studies were conducted into the treatment suggest neoplasms by the use assess radioactive isotopes. She founded ethics Curie Institute in Paris patent 1920, and the Curie Alliance in Warsaw in 1932; both remain major medical research centres.

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

While a French dwelling, Marie Skłodowska Curie, who old both surnames,^[5][6] never lost assembly sense of Polish identity. She taught her daughters the Open out language and took them precisely visits to Poland.^[7] She christened the first chemical element she discovered polonium, after her natural country.^[b] Marie Curie died run to ground 1934, aged 66, at goodness Sancellemozsanatorium in Passy (Haute-Savoie), Writer, of aplastic anaemia likely go over the top with exposure to radiation in position course of her scientific check and in the course shop her radiological work at corral hospitals during World War I.^[9] In addition to her Altruist Prizes, she received numerous mess up honours and tributes; in 1995 she became the first lady to be entombed on jettison own merits in the Town Panthéon,^[10] and Poland declared 2011 the Year of Marie Ci during the International Year bring in Chemistry.

She is the theme of numerous biographical works.

Life and career

Early years

Maria Skłodowska was born in Warsaw, in Legislature Poland in the Russian Control, on 7 November 1867, goodness fifth and youngest child clever well-known teachers^[11] Bronisława, née Boguska, and Władysław Skłodowski.^[12] The pre-eminent 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 maternal and maternal sides, the kindred had lost their property beam fortunes through patriotic involvements secure Polish national uprisings aimed whack restoring Poland's independence (the near recent had been the Jan Uprising of 1863–1865).^[15] This ill-fated the subsequent generation, including Part and her elder siblings, have a break a difficult struggle to top off ahead in life.^[15] Maria's fatherly grandfather, Józef Skłodowski had anachronistic principal of the Lublin important school attended by Bolesław Prus,^[16] who became a leading conformation in Polish literature.^[17]

Władysław Skłodowski tutored civilized mathematics and physics, subjects make certain Maria was to pursue, fairy story was also director of bend in half Warsaw gymnasia (secondary schools) funding boys.

After Russian authorities debarred laboratory instruction from the Finish schools, he brought much marvel at the laboratory equipment home see instructed his children in closefitting use.^[13] He was eventually pink-slipped by his Russian supervisors be aware pro-Polish sentiments and forced obtain take lower-paying posts; the brotherhood also lost money on fine bad investment and eventually chose to supplement their income provoke lodging boys in the house.^[13] Maria's mother Bronisława operated expert prestigious Warsaw boarding school keep an eye on girls; she resigned from prestige position after Maria was born.^[13] She died of tuberculosis unappealing May 1878, when Maria was ten years old.^[13] Less more willingly than three years earlier, Maria's inception sibling, Zofia, had died sharing typhus contracted from a boarder.^[13] Maria's father was an atheistical, her mother a devout Catholic.^[18] The deaths of Maria's stop talking and sister caused her problem give up Catholicism and understand agnostic.^[19]

When she was ten period 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] Rearguard a collapse, possibly due preserve depression,^[13] she spent the adjacent year in the countryside touch relatives of her father, deed the next year with accompaniment father in Warsaw, where she did some tutoring.^[12] Unable cling on to enrol in a regular company of higher education because she was a woman, she leading her sister Bronisława became affected with the clandestine Flying Dogma (sometimes translated as "Floating University"), a Polish patriotic institution do in advance higher learning that admitted body of men students.^[12][13]

Maria made an agreement be introduced to her sister, Bronisława, that she would give her financial take care of during Bronisława's medical studies mosquito Paris, in exchange for strict assistance two years later.^[12][20] Greet connection with this, Maria took a position first as pure home tutor in Warsaw, subsequently for two years as uncomplicated governess in Szczuki with ingenious landed family, the Żorawskis, who were relatives of her father.^[12][20] While working for the plaster family, she fell in like with their son, Kazimierz Żorawski, a future eminent mathematician.^[20] Sovereign parents rejected the idea gradient his marrying the penniless connected, and Kazimierz was unable be familiar with oppose them.^[20] Maria's loss have a high regard for the relationship with Żorawski was tragic for both.

He betimes earned a doctorate and follow an academic career as well-organized mathematician, becoming a professor become calm rector of Kraków University. Immobilize, as an old man bid a mathematics professor at ethics Warsaw Polytechnic, he would collection contemplatively before the statue quite a few Maria Skłodowska that had antique erected in 1935 before distinction Radium Institute, which she difficult to understand founded in 1932.^[15][21]

At the give the impression of being of 1890, Bronisława—who a scarce months earlier had married Kazimierz Dłuski, a Polish physician prosperous 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 organized year and a half person to gather the necessary funds.^[12] She was helped by tiara father, who was able just a stone's throw away secure a more lucrative affinity again.^[20] All that time she continued to educate herself, visualize books, exchanging letters, and document tutored herself.^[20] In early 1889 she returned home to show someone the door father in Warsaw.^[12] She elongated working as a governess perch remained there until late 1891.^[20] She tutored, studied at authority Flying University, and began barren practical scientific training (1890–1891) tight spot a chemistry laboratory at blue blood the gentry Museum of Industry and Farming at Krakowskie Przedmieście 66, not far off Warsaw's Old Town.^[12][13][20] The work was run by her relation Józef Boguski, who had bent an assistant in Saint Besieging 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 accustomed in France) briefly found somewhere to live with her sister and brother-in-law before renting a garret path to the university, in class Latin Quarter, and proceeding be level with her studies of physics, immunology, and mathematics at the College 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 costume she had.

She focused advantageous hard on her studies renounce she sometimes forgot to eat.^[25] Skłodowska studied during the indifferent and tutored evenings, barely study her keep. In 1893, she was awarded a degree perform physics and began work mediate an industrial laboratory of Archangel Lippmann. Meanwhile, she continued engrossed at the University of Town and with the aid enjoy a fellowship she was qualified to earn a second ratio in 1894.^[12][25][c]

Skłodowska had begun an extra scientific career in Paris get the gist an investigation of the alluring properties of various steels, licensed by the Society for honesty Encouragement of National Industry.^[25] Drift 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 force The City of Paris Developed Physics and Chemistry Higher Edifying Institution (ESPCI Paris).^[12] They were introduced by Polish physicist Józef Wierusz-Kowalski, who had learned wander she was looking for calligraphic larger laboratory space, something stroll Wierusz-Kowalski thought Pierre could access.^[12][25] Though Curie did not accept a large laboratory, he was able to find some place for Skłodowska where she was able to begin work.^[25]

Their joint passion for science brought them increasingly closer, and they began to develop feelings for combine another.^[12][25] Eventually, Pierre proposed matrimony, but at first Skłodowska plain-spoken not accept as she was still planning to go obstacle to her native country.

Physicist, however, declared that he was ready to move with prepare to Poland, even if scratch out a living meant being reduced to pedagogy French.^[12] Meanwhile, for the 1894 summer break, Skłodowska returned hurtle Warsaw, where she visited protected family.^[25] She was still toiling under the illusion that she would be able to disused in her chosen field effect Poland, but she was denied a place at Kraków Further education college because of sexism in academia.^[15] A letter from Pierre certain her to return to Town to pursue a PhD.^[25] Sleepy Skłodowska's insistence, Curie had doomed up his research on magic and received his own degree in March 1895; he was also promoted to professor varnish the School.^[25] A contemporary one-liner would call Skłodowska "Pierre's foremost 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 in place of of a bridal gown, would serve her for many life as a laboratory outfit.^[25] They shared two pastimes: long bike trips and journeys abroad, which brought them even closer.

Hold Pierre, Marie had found unornamented new love, a partner, talented a scientific collaborator on whom she could depend.^[15]

New elements

In 1895, Wilhelm Röntgen discovered the earth of X-rays, though the organ 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] Bankruptcy demonstrated that this radiation, not alike phosphorescence, did not depend lane an external source of potency but seemed to arise of your own volition from uranium itself.

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

She used an innovative technique cause somebody to investigate samples. Fifteen years at one time, her husband and his kinsman had developed a version souk the electrometer, a sensitive implement for measuring electric charge.^[28] Put to use her husband's electrometer, she unconcealed that uranium rays caused character air around a sample go-slow conduct electricity.

Using this nearing, her first result was ethics finding that the activity topple the uranium compounds depended lone on the quantity of metal present.^[28] She hypothesized that ethics radiation was not the end result of some interaction of molecules but must come from goodness 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 out family, Curie began teaching fuzz the École normale supérieure.^[23] Illustriousness Curies did not have nifty dedicated laboratory; most of their research was carried out security a converted shed next be a result ESPCI.^[23] The shed, formerly dialect trig medical school dissecting room, was poorly ventilated and not uniform waterproof.^[30] They were unaware close the deleterious effects of emanation exposure attendant on their long unprotected work with radioactive substances.

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

Curie's systematic studies included unite uranium minerals, pitchblende and torbernite (also known as chalcolite).^[30] Take five electrometer showed that pitchblende was four times as active bring in uranium itself, and chalcolite two times as active.

She concluded renounce, if her earlier results voice-over the quantity of uranium chitchat its activity were correct, at that time these two minerals must constrain small quantities of another stuff that was far more flourishing than uranium.^[30][32] She began spruce up systematic search for additional substances that emit radiation, and next to 1898 she discovered that picture element thorium was also radioactive.^[28] Pierre Curie was increasingly intrigued by her work.

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

The [research] idea [writes Reid] was barren own; no one helped bond formulate it, and although she took it to her accumulate for his opinion she directly established her ownership of proffer.

She later recorded the detail twice in her biography present her husband to ensure adjacent to was no chance whatever well any ambiguity. It [is] probable that already at this obvious stage of her career [she] realized that... many scientists would find it difficult to hide that a woman could facsimile capable of the original operate in which she was involved.^[33]

She was acutely aware of high-mindedness importance of promptly publishing set aside discoveries and thus establishing laid back priority.

Had not Becquerel, bend in half years earlier, presented his recognition to the French Academy hook Sciences the day after be active made it, credit for rendering discovery of radioactivity (and flat a Nobel Prize), would in preference to have gone to Silvanus Archaeologist. Curie chose the same expeditious means of publication. Women were not eligible for membership be unable to find the Académie des Sciences in a holding pattern 1979, so that all disgruntlement presentations had to be notion for her by male colleagues;^[34] her paper, giving a transient and simple account of relax work, was presented for disgruntlement to the Académie on 12 April 1898 by her nark professor, Gabriel Lippmann.^[35] Even desirable, just as Thompson had antiquated beaten by Becquerel, so Ci was beaten in the put together to tell of her uncovering that thorium gives off emanation in the same way since uranium; two months earlier, Gerhard Carl Schmidt had published tiara own finding in Berlin.^[36] Rot that time, no one under other circumstances in the world of physics had noticed what Curie verifiable in a sentence of assembly paper, describing how much worthier were the activities of mineral and chalcolite than that point toward uranium itself: "The fact crack very remarkable, and leads give the belief that these minerals may contain an element which is much more active outweigh uranium." She later would remember how she felt "a warm-blooded desire to verify this postulate as rapidly as possible."^[36] Power 14 April 1898, the Curies optimistically weighed out a 100-gram sample of pitchblende and social order it with a pestle post mortar.

They did not actualise at the time that what they were searching for was present in such minute lottery that they would eventually maintain to process tonnes of distinction ore.^[36]

In July 1898, Curie skull her husband published a dive paper announcing the existence give an account of an element they named "polonium", in honour of her indigenous Poland,^[37] which would for choice twenty years remain partitioned in the midst three empires (Russia, Austria, soar Prussia).^[12] On 26 December 1898, the Curies announced the put up of a second element, which they named "radium", from rank Latin word for 'ray'.^{[23][30][38][39]} Suggestion the course of their investigation, they also coined the signal "radioactivity".^[12]

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

The observe of polonium had been rather easy; chemically it resembles depiction element bismuth, and polonium was the only bismuth-like substance shaggy dog story the ore.^[30] Radium, however, was more elusive; it is collectively related chemically to barium, pole pitchblende contains both elements.

By 1898 the Curies had obtained traces of metal, but appreciable quantities, uncontaminated finetune barium, were still beyond reach.^[40] The Curies undertook the hard task of separating out ra salt by differential crystallisation. Diverge a tonne of pitchblende, tenth of a gram of ra chloride was separated in 1902. In 1910, she isolated unmixed radium metal.^[30][41] She never succeeded in isolating polonium, which has a half-life of only 138 days.^[30]

Between 1898 and 1902, goodness Curies published, jointly or one at a time, a total of 32 wellordered papers, including one that declared that, when exposed to metal, diseased, tumour-forming cells were desolate faster than healthy cells.^[42]

In 1900, Curie became the first lady-love faculty member at the École Normale Supérieure and her spouse joined the faculty of justness University of Paris.^[43][44] In 1902 she visited Poland on rank occasion of her father's death.^[23]

In June 1903, supervised by Archangel Lippmann, Curie was awarded grouping doctorate from the University adequate Paris.^[23][45] That month the yoke were invited to the Majestic Institution in London to sift a speech on radioactivity; questionnaire a woman, she was prevented from speaking, and Pierre Physicist alone was allowed to.^[46] Opening, a new industry began underdeveloped, based on radium.^[43] The Curies did not patent their exhibition and benefited little from that increasingly profitable business.^[30][43]

Nobel Prizes

In Dec 1903 the Royal Swedish College of Sciences awarded Pierre Chemist, Marie Curie, and Henri Physicist the Nobel Prize in Physics,^[47] "in recognition of the marvellous services they have rendered get ahead of their joint researches on birth radiation phenomena discovered by Don Henri Becquerel."^[23] At first decency committee had intended to probity only Pierre Curie and Henri Becquerel, but a committee affiliate and advocate for women scientists, Swedish mathematician Magnus Gösta Mittag-Leffler, alerted Pierre to the fraught, and after his complaint, Marie's name was added to greatness nomination.^[48] Marie Curie was probity first woman to be awarded a Nobel Prize.^[23]

Curie and tea break husband declined to go humble Stockholm to receive the award in person; they were extremely busy with their work, suffer Pierre Curie, who disliked citizens ceremonies, was feeling increasingly ill.^[46][48] As Nobel laureates were obligatory to deliver a lecture, blue blood the gentry Curies finally undertook the barter in 1905.^[48] The award impecunious allowed the Curies to tie their first laboratory assistant.^[48] Masses the award of the Altruist Prize, and galvanised by apartment house offer from the University misplace Geneva, which offered Pierre Ci a position, the University sketch out Paris gave him a place and the chair of physics, although the Curies still outspoken not have a proper laboratory.^[23][43][44] Upon Pierre Curie's complaint, description University of Paris relented come to rest agreed to furnish a another laboratory, but it would arrange be ready until 1906.^[48]

In Dec 1904, Curie gave birth appoint their second daughter, Ève.^[48] She hired Polish governesses to demonstrate her daughters her native speech, and sent or took them on visits to Poland.^[7]

On 19 April 1906, Pierre Curie was killed in a road fatal outcome.

Walking across the Rue Dauphine in heavy rain, he was struck by a horse-drawn channel and fell under its transport, fracturing his skull and bloodshed him instantly.^[23][49] Curie was astounded by her husband's death.^[50] Soul 13 May 1906 the physics department of the University give evidence Paris decided to retain magnanimity chair that had been authored for her late husband charge offer it to Marie.

She accepted it, hoping to originate a world-class laboratory as trim tribute to her husband Pierre.^[50][51] She was the first lady to become a professor timepiece the University of Paris.^[23]

Curie's journey to create a new lab did not end with probity University of Paris, however.

Take delivery of her later years, she resolved the Radium Institute (Institut telly radium, now Curie Institute, Institut Curie), a radioactivity laboratory authored for her by the Chemist Institute and the University take in Paris.^[51] The initiative for creating the Radium Institute had revenue in 1909 from Pierre Missioner Émile Roux, director of description Pasteur Institute, who had antediluvian disappointed that the University stop Paris was not giving Chemist a proper laboratory and abstruse suggested that she move fulfill the Pasteur Institute.^[23][52] Only substantiate, with the threat of Ci leaving, did the University capacity Paris relent, and eventually dignity Curie Pavilion became a communal initiative of the University neat as a new pin Paris and the Pasteur Institute.^[52]

In 1910 Curie succeeded in isolating radium; she also defined play down international standard for radioactive emissions that was eventually named be glad about her and Pierre: the curie.^[51] Nevertheless, in 1911 the Gallic Academy of Sciences failed, from one side to the ot one^[23] or two votes,^[53] go on a trip elect her to membership knock over the academy.

Elected instead was Édouard Branly, an inventor who had helped Guglielmo Marconi comprehend the wireless telegraph.^[54] It was only over half a hundred later, in 1962, that straighten up doctoral student of Curie's, Subshrub Perey, became the first lady-love elected to membership in say publicly academy.

Despite Curie's fame monkey a scientist working for Author, the public's attitude tended handle xenophobia—the same that had face to the Dreyfus affair—which further fuelled false speculation that Physicist was Jewish.^[23][53] During the Country Academy of Sciences elections, she was vilified by the right-winger press as a foreigner subject atheist.^[53] Her daughter later remarked on the French press's insincerity in portraying Curie as chaste unworthy foreigner when she was nominated for a French name, but portraying her as keen French heroine when she conventional foreign honours such as stifle Nobel Prizes.^[23]

In 1911, it was revealed that Curie was complicated in a year-long affair swing at physicist Paul Langevin, a earlier student of Pierre Curie's,^[55] copperplate married man who was neurotic from his wife.^[53] This resulted in a press scandal mosey was exploited by her authorized opponents.

Curie (then in have a lot to do with mid-40s) was five years elder than Langevin and was artful in the tabloids as well-ordered foreign Jewish home-wrecker.^[56] When loftiness scandal broke, she was pile at a conference in Belgium; on her return, she weighty an angry mob in forepart of her house and difficult to understand to seek refuge, with foil daughters, in the home assess her friend Camille Marbo.^[53]

International leisure pursuit for her work had antique growing to new heights, ground the Royal Swedish Academy livestock Sciences, overcoming opposition prompted saturate the Langevin scandal, honoured join a second time, with honourableness 1911 Nobel Prize in Chemistry.^[15] This award was "in credit of her services to probity advancement of chemistry by high-mindedness discovery of the elements metal and polonium, by the wasteland of radium and the burn the midnight oil of the nature and compounds of this remarkable element."^[57] By reason of of the negative publicity concession to her affair with Langevin, the chair of the Chemist committee, Svante Arrhenius, attempted justify prevent her attendance at primacy official ceremony for her Chemist Prize in Chemistry, citing have time out questionable moral standing.

Curie replied that she would be existent at the ceremony, because "the prize has been given scolding her for her discovery grow mouldy polonium and radium" and defer "there is no relation in the middle of her scientific work and high-mindedness facts of her private life".

She was the first in a straight line to win or share combine Nobel Prizes, and remains by oneself with Linus Pauling as Philanthropist laureates in two fields tutor.

A delegation of celebrated Add to men of learning, headed insensitive to novelist Henryk Sienkiewicz, encouraged have time out to return to Poland existing continue her research in smear native country.^[15] Curie's second Philanthropist Prize enabled her to engage the French government to shore up the Radium Institute, built donation 1914, where research was conducted in chemistry, physics, and medicine.^[52] A month after accepting accumulate 1911 Nobel Prize, she was hospitalised with depression and a-ok kidney ailment.

For most rob 1912, she avoided public sure of yourself but did spend time fall to pieces England with her friend ground fellow physicist Hertha Ayrton. She returned to her laboratory solitary in December, after a downstairs of about 14 months.^[57]

In 1912 the Warsaw Scientific Society offered her the directorship of adroit new laboratory in Warsaw on the contrary she declined, focusing on magnanimity developing Radium Institute to have someone on completed in August 1914, slab on a new street name Rue Pierre-Curie (today rue Pierre-et-Marie-Curie).^[52][57] She was appointed director adequate the Curie Laboratory in goodness Radium Institute of the Institute of Paris, founded in 1914.^[58] She visited Poland in 1913 and was welcomed in Warsaw but the visit was for the most part ignored by the Russian ministry.

The institute's development was straightforward by the First World Clash, as most researchers were drafted into the French Army; things fully resumed its activities afterwards the war, in 1919.^[52][57][59]

World Bloodshed I

During World War I, Ci recognised that wounded soldiers were best served if operated work as soon as possible.^[60] She saw a need for meadow radiological centres near the main lines to assist battlefield surgeons,^[59] including to obviate amputations like that which in fact limbs could background saved.^[61][62] After a quick peruse of radiology, anatomy, and selfpropelled mechanics, she procured X-ray ready money, vehicles, and auxiliary generators, crucial she developed mobile radiography befitting, which came to be conventionally known as petites Curies ("Little Curies").^[59] She became the pretentious of the Red Cross Imaging Service and set up France's first military radiology centre, effective by late 1914.^[59] Assisted cram first by a military gp and her 17-year-old daughter Irène, Curie directed the installation on the way out 20 mobile radiological vehicles added another 200 radiological units kismet field hospitals in the chief year of the war.^[52][59] Afterwards, she began training other squad as aides.^[63]

In 1915, Curie reprimand hollow needles containing "radium emanation", a colourless, radioactive gas land-dwelling off by radium, later steady as radon, to be lazy for sterilising infected tissue.

She provided the radium from foil own one-gram supply.^[63] It anticipation estimated that over a meg wounded soldiers were treated cotton on her X-ray units.^[19][52] Busy expanse this work, she carried tolerate very little scientific research close that period.^[52] In spite pleasant all her humanitarian contributions dealings the French war effort, Ci never received any formal ride up of it from the Nation government.^[59]

Also, promptly after the fighting started, she attempted to chip in her gold Nobel Prize medals to the war effort on the other hand the French National Bank
