Marie Curie, born Marie Sklodowska, grew up in Poland, a police state under the Russian czar Alexander II. Her mother was headmistress of a prestigious girls'.

Marie Skłodowska Curie was a Polish and naturalized-French physicist and chemist who The deaths of Maria's mother and sister caused her to give up Catholicism and become agnostic. . Eventually Pierre Curie proposed marriage , but at first Skłodowska did not accept as she was still planning to go back to her native.
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.
Polonium was a new chemical element, atomic number 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. 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 Marie eventually isolated radium as radium chloridedetermining its atomic weight as The journey to the discovery had been long and arduous. In the same year, Marie passed her doctorate thesis in Physics. In 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 inthis 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.

- The Curies: A Biography of the Most Controversial Family in Science
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 Octoberthe 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.
The technology Marie Curie developed for the "Petits Curies" is similar to that used today in the fluoroscopy machine at our Hampstead hospice. A powerful X-ray machine, it allows doctors to examine moving images in the body, such as pumping action of the heart or the motion of swallowing. After the war, Marie continued her work as a researcher, teacher and head of a laboratory and received many awards and prizes. She was also the recipient of many honorary degrees from universities around the world.
Opened init was staffed entirely by women to treat female cancer patients using radiology. It also had research facilities. Now, in the 21st century, Marie Curie is a major UK charity for people living with any terminal illness, not just cancer, and their families. Their joint researches into radioactive polonium and radium, painstakingly separated from several tons of pitchblende, earned them the Nobel Prize in physics with Henri Becquerel.
Eight years later, Marie Curie earned a second Nobel Prize, in chemistry, for the separation of polonium and radium. Marie became not only the first woman in science to earn 2 Nobel Prizes but also the first woman to be appointed professor at the Sorbonne.
The book is not limited to just the scientific achievements of the Curies; the author also focuses on the lesser known controversial events in their lives. Pierre afterward would take notes describing levitating tables and mysterious music heard in the distance.The Afterlife Interview with Marie Curie
The book also describes how the Curies dealt with the public recognition that accompanied their professional achievements, including the scandalous love affair made public between Marie Curie and her physicist colleague Paul Langevin.
The scandal escalated to such heights that many journalists and editors, as well as Langevin himself, fought duels over the honor of Madame Curie. Many wondered how Marie, a dignified and reserved scientist seemingly devoted to her work, could be involved with breaking up homes and dishonoring her name. In contrast, Eve Curie, not having the scientific predisposition of the rest of her family, sought to make her mark in music.
Later, she turned to journalism and provided the most famous biography of her mother. The final chapter of the book discusses the further achievements of the offspring of the Curies.
