She had been away in Belgium when the scandal broke, and in those first days she could only imagine what was being said about her in Paris. But when Marie Curie finally returned to her home, she found the truth waiting at her doorstep: an angry mob had gathered in front of the house. No one knows what they intended to do to her. She did not stay to find out.

She fled to a friend’s home, and even Albert Einstein wrote to comfort her, urging her to ignore the sensationalist press. The greatest woman scientist of her age, the first person in history to win a Nobel Prize, had been reduced to the subject of a gutter scandal that her enemies used with relish. It had not always been like this. It had begun in Warsaw on November 7, 1867, when she was born Maria Salomea Skłodowska, the youngest of five children of two teachers, Bronisława and Władysław Skłodowski.

Poland at the time was a semi-independent entity within the Russian Empire, known as Congress Poland, and her family’s poverty was in part a legacy of their ancestors’ participation in failed uprisings against the empire. As punishment, their wealth and property had been confiscated. But her parents, both educators, instilled in their children a passion for knowledge that no confiscation could take away. Maria’s first experiences with applied science came through an act of political suppression.

Her father, a teacher of mathematics and physics, was forbidden from teaching laboratory courses in Polish schools. So he brought all his equipment home and allowed his children to use it. Maria was an outstanding student, graduating from secondary school early, at the age of fifteen. But her life was not all smooth.

After school she suffered from nervous problems, which in our time would likely have been classified as depression. She spent time in the countryside to recover, and then decided to pursue higher education. When she returned to Warsaw, she discovered that she was barred from attending any university simply because she was a woman. To work around the ban, she joined what was called the “Flying University,” a secret, nationalistic Polish institution that operated in hiding, offering evening lessons away from the eyes of the tsarist authorities and admitting women.

She and her sister, Bronisława, both received their university education there. Soon the two sisters made a mutually beneficial arrangement: Maria would work as a private tutor in Warsaw to support Bronisława’s move to Paris to study medicine. In return, Bronisława agreed to help Maria financially after two years from her graduation. Maria spent a brief period tutoring in Warsaw before moving to a small town in the Polish countryside, where she worked as a governess and lived with her father’s wealthy relatives, the Żorawski family.

There she fell in love with Kazimierz, the family’s son, who would later become a mathematician. The two young people decided to marry, but they faced obstacles. Kazimierz’s parents refused, despite loving Maria. They would not let their son marry a poor girl.

The engagement ended quickly. The rejection left Maria deeply hurt and insulted. She retreated into what she did best: she immersed herself in scientific books and pursued knowledge. Over the next few years she continued working toward her dream of becoming a scientist in Paris, taking various jobs and earning varying amounts of money to fund her future travels and her sister’s education.

By 1891, at the age of twenty-four, the time had come for her to travel to Paris. As soon as she arrived, she got to work. After a brief stay with her sister and brother-in-law, she found modest lodgings near the University of Paris, where she enrolled to study physics, chemistry, and mathematics. She lived simply so as not to distract herself from her studies, which consumed her so completely that she sometimes forgot to eat.

Once she even fainted from hunger. To cut expenses, she gave up heating her home and simply wore as many layers of clothing as she could. Her efforts paid off when she earned a degree in physics in 1893. She had finally achieved her dream of becoming a scientist, and she began working in a laboratory.

The work funded her graduate studies, and a year later she earned a second degree, this time in chemistry. Through her work she met the scientist Pierre Curie. Their shared interests drew them together, and before long love grew between them. Pierre proposed to Marie.

She initially refused, declaring that she planned to return to live and work in her homeland, Poland. But Pierre, deeply in love, was not deterred. He said he would follow her to Poland and teach her French if necessary. In 1894, Marie returned to Warsaw to visit her family and look for work in her field.

But things were not as they were in Paris. When she applied for a position at the University of Kraków, her application was rejected. The reason? She was a woman.

Marie was not happy about the rejection and told Pierre, who was equally saddened. He replied with a letter urging her to return to Paris and continue her studies. He convinced her that France was the only place where her talent could truly flourish. She returned to France, and the two married in a civil ceremony on July 26, 1895.

Not being the romantic type, Marie wore a dark blue dress instead of the traditional white wedding gown. She wore the same dress for years afterward in the laboratory, because it was practical and did not easily show dirt or chemical stains. They were perfectly matched, sharing many interests including cycling and travel, and above all, a love of science. By all accounts their marriage was happy, and they had two daughters.

In 1895, the scientific community was stirred by a new discovery: X-rays. Marie Curie was immediately fascinated and shifted her focus to research into radioactivity. Working with her husband, she discovered the element radium. Her pioneering research led her to coin the term “radioactivity.

” Soon a huge and highly profitable industry grew up around the element. But the Curies never saw the fruits of their labor. True to their ethics, they humbly refused to patent their discovery, believing that scientists should focus on the benefit of humanity rather than personal gain. That modesty perhaps explains why the couple did not have a proper laboratory for their research.

They worked in a converted shed. The shed lacked ventilation, its roof leaked, and it was freezing in winter and sweltering in summer. In hindsight, this was a very bad idea when working with radiation. The Curies were not fully aware of the serious dangers of radiation exposure.

Radium was not the only elemental discovery made by the Curies. Shortly before that groundbreaking discovery, the couple had found another new element, which they named polonium, in honor of Marie’s homeland. Despite all the rejection she had suffered there, she still loved her country deeply and hoped that this tribute would draw the world’s attention to Poland’s struggle for independence. Their research on radioactivity did not go unnoticed.

For their significant contributions, they were jointly awarded the Nobel Prize in Physics in 1903. Initially, the Swedish Academy had planned to honor only Pierre and Henri Becquerel, but Pierre insisted that Marie receive the same recognition. This was an unprecedented achievement: Marie was the first woman in history to receive the prize. It was also the first time a married couple had won a Nobel Prize.

It was the first of many achievements for the Curie family, which would eventually collect five Nobel Prizes. Then, in 1906, tragedy: a horse-drawn carriage struck Pierre, killing him. This was incredibly hard on Marie, but in a strange way it advanced her career. Pierre had held a position in the physics department at the University of Paris.

In recognition of the couple’s efforts, the university offered the position to Marie after his death. She accepted, becoming the university’s first female professor. Over the next five years, Marie continued her important research with the support of university resources. For the most part, the press left her alone.

That changed in 1911, when a shocking story broke. It turned out that Marie had been having an affair with Paul Langevin, a married man who had been a student of her late husband. The media whipped up a scandal that her academic rivals exploited. Curie was five years older than Langevin, so she was portrayed as having taken advantage of the younger man.

Many newspapers defamed her for her foreign origins, and she was even subjected to baseless anti-Semitic attacks. Despite the scandal, she was awarded another Nobel Prize, this time in chemistry, in 1911. It was another significant achievement: she became the first person to win a Nobel Prize twice, and the first to win in two different fields, physics and chemistry. But for whatever reason, despite these accomplishments, Marie’s mental health soon deteriorated badly.

Just one month after accepting the prize, she was hospitalized for kidney problems and depression. After that, she stayed out of public view for fourteen months. Everything changed with the outbreak of the First World War. Marie spurred herself to harness her scientific abilities for positive change.

She realized that wounded soldiers’ chances of survival improved if they underwent immediate surgery, so she developed mobile X-ray units so that field hospitals could perform X-ray examinations. These units were known among the French troops as “Petite Curies. ” To support the French war effort further, Marie offered to donate her Nobel Prize medals to the French National Bank. Since they were made of gold, she hoped their value would add to the bank’s treasury.

Her offer was politely declined. But she spent what remained of her Nobel Prize money buying war bonds. The French never forgot her generosity. After the war, Marie founded the Curie Institute in Paris, a private, non-profit institution conducting research in medicine, biology, and biophysics.

Twelve years later, despite all the difficulties she had faced as a woman in Poland, she founded a second Curie Institute in Warsaw. It became a lasting testament to her legacy; both institutes remain active centers of medical research to this day. Marie died in 1934 in the mountains of southeastern France. The cause of death was aplastic anemia, which had damaged her bone marrow.

It is believed that this condition was the result of prolonged radiation exposure throughout her career, as well as her unprotected exposure to radium and X-rays during the First World War. Even her laboratory notebooks, diaries, and personal papers remain contaminated with radium 226 today. They are kept in lead-lined boxes, and any researcher who wishes to handle them must wear protective equipment.

The French Republic honored Marie’s legacy by burying her remains in the Panthéon in Paris, the nation’s highest tribute.
