"The radiation also contaminated everything she owned or worked with–which means that her papers are stored in a lead-lined box and you have to sign a liability waiver to access them, writes Adam Clark Estes for Gizmodo. “And it’s not just Curie’s manuscripts that are too dangerous to touch, either,” he writes. “If you visit the Pierre and Marie Curie collection at the Bibliotheque Nationale in France, many of her personal possessions—from her furniture to her cookbooks—require protective clothing to be safely handled.”

Curie’s early career unfolded entirely in Europe, but she did eventually make it to the United States–twice, in fact.  Her first visit, in 1921, saw her visit the White House to receive a gram of radium for her work, crowdfunded by American women.  At that time, she met president Warren G. Harding.

When she returned in 1929, again to receive supplies for her work, she met president Herbert Hoover.

When her sister offered her lodgings in Paris with a view to going to university, she grasped the opportunity and moved to France in 1891.

She immediately entered Sorbonne University in Paris where she read physics and mathematics – she had naturally discovered a love of the subjects through her insatiable appetite for learning.

It was in Paris, in 1894, that she met Pierre Curie – a scientist working in the city – and who she married a year later. It was also around this time that she adopted the French spelling of her name – Marie.

On 4 July 1934, at the Sancellemoz Sanatorium in Passy, France at the age of 66, Marie Curie died. The cause of her death was given as aplastic pernicious anaemia, a condition she developed after years of exposure to radiation through her work.

She left two daughters, Irene (born 1898) and Eve (born 1904).

Irene, like her mother, entered the field of scientific research and, with her husband Frederic Joliot, worked on the nucleus of the atom and together were awarded a Nobel Prize and credited with the discovery of artificial radiation. Irene too died of a radiation-related illness – leukaemia – in 1956.

Eve became a journalist and writer.

Irene's daughter Dr Hélène Langevin-Joliot (born 1927) also pursued a career in nuclear physics and became research emeritus of the National Centre for Scientific Research in Paris.
In 1995, Marie and Pierre Curie were reburied in the Pantheon – the Paris mausoleum reserved for France's most revered dead – on the orders of French President Mitterand.

Marie Curie was the first woman to be awarded a place in the Pantheon for her own achievements.

The Curies became research workers at the School of Chemistry and Physics in Paris and there they began their pioneering work into invisible rays given off by uranium – a new phenomenon which had recently been discovered by Professor Henri Becquerel.

He had shown that the rays were able to pass through solid matter, fog and photographic film and caused air to conduct electricity.

Marie also noticed that samples of a mineral called pitchblende, which contains uranium ore, were a great deal more radioactive than the pure element uranium. Further work convinced her the very large readings she was getting could not be caused by uranium alone – there was something else in the pitchblende. Since nobody had ever found it before, it could only be present in tiny quantities, and it seemed to be very radioactive. Marie was convinced she had found a new chemical element – other scientists doubted her results.

Pierre and Marie Curie set about working to search for the unknown element. They ground up samples of pitchblende, dissolved them in acid, and began to separate the different elements present, using the standard analytical chemistry techniques of the time. Eventually, they extracted a black powder 330 times more radioactive than uranium, which they called polonium  . Polonium was a new chemical element, atomic number 84.

Born Maria Sklodowska on 7 November 1867 in Warsaw, Poland, she was the youngest of five children of poor school teachers.

After her mother died and her father could no longer support her she became a governess, reading and studying in her own time to quench her thirst for knowledge. She never lost this passion.

She was educated in secret

Curie was raised in Warsaw, Poland, which at that time was controlled by the Russian Empire. She got her university education at the Flying University, a secret Polish university that educated women in shifting locations.  At the time, writes Eric Grundhauser for Atlas Obscura, educating women at university was illegal in Russia. Additionally, he writes, “the Germanization and Russification efforts (depending on what political power controlled the part of Poland where you lived) aimed at higher education made it nearly impossible for the citizenry to take part in a curriculum that wasn’t in some way working to erase Polish culture.”

Over time, as the university formalized, the freedom to teach what they wanted, to whomever they wanted, attracted Poland’s top minds. And Curie learned from those minds.

"I am one of those who think like Nobel, that humanity will draw more good than evil from new discoveries."

"I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale."

"Humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit."

In 1903 Marie and Pierre were awarded the Nobel Prize for Physics jointly with Henri Becquerel for their combined, though separate, work on radioactivity.

In the same year, Marie passed her doctorate thesis in Physics.

In 1906 Marie's life was struck by tragedy when Pierre was killed in a street accident after being knocked down by a horse and cart. Her indomitable spirit, however, kept her working and she went on to succeed him in his Chair as Professor at Sorbonne, as well as carrying on lecturing where he had left off.

Her determination and remarkable endeavours led to a second Nobel Prize in 1911, this time in chemistry for creating a means of measuring radioactivity. Not long after, Sorbonne built the first radium institute with two laboratories; one for study of radioactivity under Marie Curie's direction, and the other for biological research into the treatment of cancer.

During the First World War, Marie Curie worked to develop small, mobile X-ray units that could be used to diagnose injuries near the battlefront. As Director of the Red Cross Radiological Service, she toured Paris, asking for money, supplies and vehicles which could be converted.

In October 1914, the first machines, known as "Petits Curies", were ready, and Marie set off to the front. She worked with her daughter Irene, then aged 17, at casualty clearing stations close to the front line, X-raying wounded men to locate fractures, bullets and shrapnel.

After the war, Marie continued her work as a researcher, teacher and head of a laboratory and received many awards and prizes. Among them were the Ellan Richards Research Prize (1921), the Grand Prix du Marquis d'Argenteuil (1923) and the Cameron Prize from Edinburgh University (1931). She was also the recipient of many honorary degrees from universities around the world.

Here are 10 things you need to know about the two-time Nobel Prize winner, whose groundbreaking work on radioactivity made her one of the most famous scientists of all time.

1. She was born Maria Sklodowska on November 7 1867 in Warsaw, Poland. She met her scientist husband, Pierre Curie, in Paris in 1894, and they married a year later. It was around this time that she adopted the French spelling of her name – Marie.

2. In 1903, she shared the Nobel Prize for Physics with French physicist Henri Becquerel and her husband for their work on radioactivity. Her name was initially left off the winners’ list but Pierre insisted she be included. She thus became the first woman to win a Nobel Prize.

3. Becquerel inspired the Curies to investigate radioactivity after its discovery in 1896. They examined a mineral called pitchblende and eventually found two radioactive elements – radium and polonium. Curie named polonium after her home country.

4. Curie’s life was struck by tragedy in 1906 when Pierre was killed in a carriage accident. She went on to succeed him as a professor at the Sorbonne in Paris and devoted herself to continue the work they had begun together.

5. In 1911, she was awarded the Chemistry Prize – becoming the first person to win two Nobels.

6. Curie’s daughter, Irene Joliot-Curie, also won the Nobel Prize in Chemistry, jointly with her husband, Frederic Joliot-Curie, in 1935. They are the only mother-daughter pair to have won Nobel Prizes.

7. During the First World War, Curie worked to develop small, mobile X-ray units that could be used to diagnose injuries near the battlefront. The first machines were known as Petits Curies.

8. Curie was keen to continue her work after the war. In 1929, US President Herbert Hoover presented Curie with a gift of 50,000 US dollars, donated by American friends of science, to purchase radium for use in the laboratory in Warsaw.

9. She died on July 4 1934 from leukaemia, believed to have been caused by exposure to radiation from her research.

10. Curie’s 150th birthday – 7/11/17 – is a palindrome date.

When the Curies investigated further, they found that the liquid left behind after they had extracted polonium was still extremely radioactive. They realised that pitchblende contained another new element, far more radioactive than polonium, but present in even smaller quantities.

In 1898, the Curies published strong evidence supporting the existence of the new element – which they called radium   – but they still had no sample of it. Pitchblende is an expensive mineral, because it contains valuable uranium, and Marie needed a lot of it.

She got in touch with a factory in Austria that removed the uranium from pitchblende for industrial use and bought several tonnes of the worthless waste product, which was even more radioactive than the original pitchblende, and was much cheaper. Marie set about processing the pitchblende to extract the tiny quantities of radium. This involved working on a much larger scale than before, with 20 kg batches of the mineral – grinding, dissolving, filtering, precipitating, collecting, redissolving, crystallising and recrystallising.

The work was heavy and physically demanding – and involved dangers the Curies did not appreciate. During this time they began to feel sick and physically exhausted; today we can attribute their ill-health to the early symptoms of radiation sickness. At the time they persevered in ignorance of the risks, often with raw and inflamed hands because they were continually handling highly radioactive material.

In 1902 Marie eventually isolated radium (as radium chloride), determining its atomic weight as 225.93. The journey to the discovery had been long and arduous.
