Marie Curie: A Life in the Service of Science

Marie Curie’s name is inseparable from the history of modern science. Born Maria Salomea Skłodowska in Warsaw in 1867, she became a physicist and chemist whose investigations transformed scientific understanding of radioactivity. She was also the first woman to receive a Nobel Prize—and the first, and still only, person to receive Nobel Prizes in two different scientific categories: Physics and Chemistry. (Nobel Prize). She died in 1934 from aplastic anemia.

Her story began in a Poland then under Russian rule, continued in the laboratories of Paris, and ultimately changed the way scientists understood matter itself.

From Warsaw to Paris

Maria Skłodowska was born in Warsaw on November 7, 1867, into a family of teachers. Education was deeply valued in her household, and her father introduced her to physics and chemistry at an early age. Yet the political circumstances of nineteenth-century Poland placed significant restrictions on higher education for women.

Marie was an exceptionally able student, but university education was not readily available to Polish women. She and her sister Bronisława therefore developed a plan: Marie would work and help finance her sister's medical studies, after which her sister would help finance Marie's education.

At 24, Maria finally left Poland for Paris. In 1891 she enrolled at the Sorbonne, adopting the French form of her name, Marie. She studied physics and mathematics with extraordinary intensity, earning her degree in physical sciences in 1893 and mathematics in 1894. (Nobel Prize)

Paris would become her permanent scientific home.

Marie and Pierre Curie

Marie met physicist Pierre Curie in 1894. They married in 1895, beginning one of the most famous scientific partnerships in history.

Their partnership was not simply a marriage between two scientists. It became a sustained collaboration built around experimentation, measurement and an extraordinary willingness to investigate a phenomenon that was still poorly understood.

In 1896, Henri Becquerel discovered that uranium emitted spontaneous radiation. Marie Curie began investigating this phenomenon for her doctoral research. She discovered that the radiation came from the atoms themselves and demonstrated that the phenomenon was not limited to uranium. (Nobel Prize)

She eventually gave the phenomenon its enduring scientific name: radioactivity.

The Discovery of Polonium

Marie and Pierre Curie examined the mineral pitchblende, which was known to contain uranium. They noticed something remarkable: some samples were considerably more radioactive than the amount of uranium they contained could explain.

This suggested that another radioactive substance was present.

Their painstaking investigations led to the identification of a previously unknown element, which Marie named polonium, after her native Poland.

The discovery was followed by another, even more consequential discovery.

The Discovery of Radium

The Curies found evidence of another radioactive substance in pitchblende. They named it radium, from the Latin radius, meaning "ray."

Extracting and studying radium was extraordinarily laborious. Marie processed enormous quantities of radioactive material through repeated chemical separations. Nobel Prize historical material records that she ultimately isolated highly purified radium chloride and determined its atomic weight as part of the work that formed her doctoral research. (Nobel Prize)

The significance extended beyond the discovery of a new element. Radioactivity provided scientists with evidence that the atom was not the immutable, indivisible object that had long been imagined.

Marie Curie's work therefore contributed to a fundamental transformation in modern physics and chemistry.

The 1903 Nobel Prize in Physics

In 1903, Marie Curie received the Nobel Prize in Physics, jointly with Pierre Curie and Henri Becquerel.

The Nobel Committee recognized their work concerning the radiation phenomena discovered by Becquerel. Becquerel received one-half of the prize, while Marie and Pierre Curie shared the other half. Marie therefore received one-quarter of the total prize. (Nobel Prize)

This made Marie Curie the first woman ever to receive a Nobel Prize.

The recognition was particularly significant because Marie's contribution had initially been overlooked in some of the early nomination discussions. Pierre Curie insisted that her scientific contribution be recognized alongside his own. Nobel's historical account records his efforts to ensure that Marie was included. (Nobel Prize)

The prize recognized work that had been conducted under difficult laboratory conditions, with relatively primitive facilities and extensive physical labour.

Tragedy and a New Chapter

Marie and Pierre had two daughters, Irène and Ève. Their scientific partnership and family life were abruptly altered in 1906 when Pierre Curie died in a street accident in Paris.

Marie continued their scientific work.

She succeeded Pierre at the Sorbonne, becoming the first woman to hold a professorship there. She also assumed responsibility for the laboratory and continued her investigations into radioactive substances. (Nobel Prize)

Rather than ending her scientific career, Pierre's death marked the beginning of a remarkable new chapter in which Marie worked increasingly as an independent scientist.

The 1911 Nobel Prize in Chemistry

Eight years after her first Nobel Prize, Marie Curie received a second.

In 1911, she was awarded the Nobel Prize in Chemistry for her work on radioactivity, including the discovery of radium and polonium, the isolation of radium, and the investigation of the properties and compounds of this remarkable element. (Nobel Prize)

This was a very different recognition from the 1903 Physics Prize.

The first Nobel recognized the investigation of radiation phenomena; the second recognized Marie's extensive chemical work establishing radioactive elements and studying their properties.

With the 1911 award, Marie Curie became the first person ever to receive two Nobel Prizes. She remains the only individual to have received Nobel Prizes in two different scientific categories. (Nobel Prize)

Science in the Service of Medicine

Marie Curie's interest in radioactivity was never confined to theoretical science.

She was deeply interested in its practical and medical possibilities. During the First World War, she helped establish mobile radiography units that brought X-ray technology closer to wounded soldiers. She worked with her daughter Irène in this effort, helping train personnel and supporting the use of radiological equipment in military medicine. (Nobel Prize)

Her scientific discoveries would eventually become part of the foundations upon which radiation-based medical diagnosis and treatment developed.

The institutions associated with her work continued that legacy. The Radium Institute became an important centre for research into radioactivity and its biological and medical applications, ultimately contributing to the institution known today as the Institut Curie.

A Family of Scientists

Marie Curie's scientific legacy continued through her children.

Her elder daughter, Irène Joliot-Curie, became a scientist in her own right. In 1935, Irène and her husband, Frédéric Joliot-Curie, received the Nobel Prize in Chemistry for their discovery of artificial radioactivity. (Nobel Prize)

Marie therefore became not only a Nobel laureate herself, but the mother of another Nobel Prize-winning scientist.

Her Final Years

Marie Curie continued scientific work throughout her later life. She participated in international scientific organizations, published important scientific works and supported the development of laboratories dedicated to radioactive research.

She died in France on July 4, 1934, at the age of 66. (Nobel Prize)

Her prolonged exposure to radiation occurred during an era when the dangers of ionizing radiation were not yet fully understood. Today, her laboratory notebooks and other materials require special handling because of their continuing radioactivity.

In 1995, Marie Curie and Pierre Curie were transferred to the Panthéon in Paris. Marie became the first woman to be interred there for her own achievements. (Centre des Monuments Nationaux)

Two Nobel Prizes, One Extraordinary Scientific Legacy

Marie Curie's two Nobel Prizes represent two stages of a scientific journey.

1903 — Nobel Prize in Physics
Marie Curie, Pierre Curie and Henri Becquerel were recognized for their work concerning the radiation phenomena discovered by Becquerel.

1911 — Nobel Prize in Chemistry
Marie Curie was recognized for her discoveries of radium and polonium, the isolation of radium, and her investigations into radioactive substances.

But the significance of Marie Curie's career cannot be reduced to two medals.

She helped establish radioactivity as a field of scientific study, discovered two elements, developed methods for isolating radioactive substances, demonstrated that radiation originated from within atoms, advanced the scientific study of radium, helped bring X-ray technology into wartime medicine, and established institutions that continued radioactive research long after her death. (Nobel Prize)

Her life also illustrates the extraordinary distance between where she began and where her work ultimately led: a young woman born in Warsaw when higher education was largely closed to women in her country became a professor at the Sorbonne, the first woman to win a Nobel Prize, and the first person to win two Nobel Prizes.

Marie Curie's legacy is therefore not simply the story of a famous scientist. It is the story of curiosity pursued with extraordinary persistence—and of scientific discovery changing the understanding of the natural world.
