• Director of the Curie Laboratory at the Radium Institute
• Pioneer in radioactivity research
• Developer of mobile X-ray units during World War I
• Advocate for scientific education and international collaboration

Era

Marie Curie worked during the transformative period of late 19th and early 20th century science, when physics and chemistry were undergoing revolutionary changes. Her career coincided with the discovery of X-rays by Wilhelm Röntgen (1895), the discovery of radioactivity by Henri Becquerel (1896), and the development of quantum mechanics and atomic theory. She lived through World War I, the interwar period, and the early years of fascism in Europe.

Introduction

Marie Curie stands as one of the most influential scientists in human history and the most iconic female scientist of all time. Her pioneering research on radioactivity fundamentally transformed our understanding of matter and energy, laying groundwork for nuclear physics, cancer treatment, and numerous medical and industrial applications.

Curie’s achievements are all the more remarkable given the obstacles she faced as a woman in science at the turn of the 20th century. Denied higher education in her native Poland because of her gender, she pursued her studies in Paris at the Sorbonne, often enduring poverty and hardship. Despite these challenges, she graduated at the top of her class and went on to conduct research that would earn her international recognition.

Her collaboration with her husband Pierre Curie led to the isolation of two new elements: polonium (named after her homeland) and radium. Their work on radioactivity—Marie coined the term “radioactivité”—demonstrated that certain elements emitted powerful rays capable of penetrating solid matter and affecting photographic plates. This discovery challenged existing scientific paradigms and opened entirely new fields of research.

In 1903, Marie Curie became the first woman to win a Nobel Prize, sharing the Physics Prize with Pierre Curie and Henri Becquerel for their work on radioactivity. When she won the Nobel Prize in Chemistry in 1911—becoming the first person to win Nobel Prizes in two different scientific fields—she did so independently, following Pierre’s tragic death in 1906. Her second prize recognized her discovery of radium and polonium and her isolation of radium in its pure metallic state.

During World War I, Curie developed mobile radiography units, known as “Little Curies,” which provided X-ray services to field hospitals. She personally drove these units to the front lines, training women as radiological technicians and treating over a million wounded soldiers.

Marie Curie’s dedication to science came at a terrible personal cost. Working with radioactive materials before the dangers of radiation were understood, she suffered from chronic health problems throughout her life. She carried test tubes of radium in her pockets, worked in primitive laboratory conditions, and kept detailed notes that remain radioactive to this day. Her death from aplastic anemia in 1934 was almost certainly caused by radiation exposure.

Beyond her scientific achievements, Curie was a passionate advocate for scientific education, international scientific cooperation, and the application of science for humanitarian purposes. She founded the Radium Institute in Paris (now the Curie Institute), which remains a leading cancer research center. Her daughter Irène Joliot-Curie continued her work, winning the Nobel Prize in Chemistry in 1935, making them the first mother-daughter Nobel laureates.

Marie Curie’s legacy extends far beyond her discoveries. She shattered gender barriers in science, inspired generations of women to pursue scientific careers, and demonstrated that rigorous scientific inquiry could coexist with humanitarian concern. Her life exemplifies the power of intellectual curiosity, perseverance, and dedication to the pursuit of knowledge.

Early Life of Marie Curie

Family Background

Maria Salomea Skłodowska was born on November 7, 1867, in Warsaw, Poland, which was then part of the Russian Empire following the partitions of Poland in the late 18th century. Her father, Władysław Skłodowski, was a teacher of physics and mathematics who taught at a secondary school for boys. He lost his position after Russian authorities reduced science teaching in Polish schools, eventually becoming director of a boarding school. Her mother, Bronisława Boguska, operated a prestigious girls’ boarding school in Warsaw.

The Skłodowski family belonged to the Polish intellectual and professional class, with strong traditions of education and patriotism. They were not wealthy but valued learning highly. Marie was the youngest of five children: - Zofia (born 1862) - Józef (born 1863) - Bronisława (born 1865) - Helena (born 1866) - Maria (born 1867)

Childhood in Occupied Poland

Marie’s early years were marked by both intellectual stimulation and personal tragedy. Her parents ran schools that created an environment of learning, and the family home was filled with books and discussions of science, literature, and Polish culture. However, the family faced significant hardships:

Illness and Loss: - In 1876, Marie’s oldest sister Zofia died of typhus contracted from a boarder at their mother’s school - In 1878, when Marie was only ten, her mother died of tuberculosis - These losses devastated the family and deeply affected young Marie, who struggled with depression throughout her childhood

Political Oppression: - The Russian Empire strictly controlled Polish education, forbidding the teaching of Polish history and language - Marie attended a clandestine “Floating University” where Polish intellectuals taught subjects forbidden by Russian authorities - Her father brought home laboratory equipment from his school, and Marie and her siblings conducted simple chemistry experiments

Education

Marie demonstrated exceptional intelligence from an early age. Her formal education began at a gymnasium for girls in Warsaw, where she graduated with a gold medal in 1883 at age 15. She excelled particularly in mathematics and physics but also studied literature and languages.

After graduation, she spent a year in the countryside with relatives, recovering from the exhaustion of her studies and the emotional toll of her family’s losses. During this period, she read extensively and developed her characteristic determination and self-discipline.

The “Floating University”: - Upon returning to Warsaw, Marie attended the underground “Floating University” (Uniwersytet Latający) - This secret institution allowed Polish students to receive higher education despite Russian prohibitions - She studied science, philosophy, and literature while working as a governess to support herself

The Agreement with Bronia

Marie and her older sister Bronisława made a pact that would change both their lives. Bronia dreamed of studying medicine in Paris, and Marie wanted to pursue science. Since their family could not afford to send both daughters abroad simultaneously, they agreed:

1. Marie would work as a governess to support Bronia’s studies in Paris
2. Once Bronia completed her education and began practicing medicine, she would support Marie’s studies

For nearly five years, from 1885 to 1890, Marie worked as a governess for wealthy families in Poland. She taught the children of the Żorawski family in Szczuki, near Płock, and later for other families. During this period: - She continued her self-education, studying physics and chemistry textbooks - She established a secret school for Polish peasant children, teaching them to read (illegal under Russian rule) - She fell in love with Kazimierz Żorawski, the son of her employers, but the family rejected her as unsuitable due to her lack of fortune

Journey to Paris (1891)

In November 1891, at age 24, Marie finally made the journey to Paris. She traveled by train from Warsaw to Paris, carrying minimal possessions but a wealth of determination. Her sister Bronia was now married to a fellow Polish medical student, and the couple provided Marie with a place to live.

Arrival at the Sorbonne: - Marie enrolled at the Sorbonne (University of Paris) to study physics and mathematics - She initially lived with Bronia but moved to a garret near the university to be closer to her studies - Her living conditions were extremely poor: unheated rooms, inadequate food, often fainting from hunger

Despite these hardships, Marie thrived academically. She studied with legendary intensity, sometimes forgetting to eat. She earned her degree in physics in 1893, ranking first in her class, and her degree in mathematics in 1894, ranking second. Her exceptional performance attracted the attention of Gabriel Lippmann, who offered her a research position studying magnetic properties of steel.

Meeting Pierre Curie (1894)

In the spring of 1894, Marie was looking for laboratory space to conduct her research. A Polish physicist introduced her to Pierre Curie, a physicist eight years her senior who was already recognized for his work on crystallography and magnetism. Pierre was the laboratory chief at the Municipal School of Industrial Physics and Chemistry in Paris.

Their first meeting was significant but not immediately romantic. Pierre was immediately impressed by Marie’s intelligence and dedication. He helped her find laboratory space, and their professional relationship gradually developed into friendship and then love.

Pierre proposed marriage, but Marie initially hesitated. She had planned to return to Poland after completing her studies and feared that marriage would trap her in France, away from her family and homeland. However, Pierre promised to follow her anywhere, even to Poland. In 1894, Marie returned to Warsaw hoping to find an academic position, but was rejected by Kraków University because she was a woman.

Realizing that her scientific future lay in France, Marie accepted Pierre’s proposal. They married on July 26, 1895, in a simple civil ceremony. Marie wore a dark blue outfit that she would use as a laboratory dress for years afterward. Instead of a honeymoon, they spent their wedding money on bicycles and embarked on a cycling tour of the French countryside—an activity they would enjoy throughout their marriage.

The Beginning of Scientific Collaboration

After their marriage, Marie and Pierre established a home and laboratory. Their partnership was revolutionary for its time: they were intellectual equals who collaborated on scientific research while raising a family. Pierre’s support was crucial to Marie’s success; he recognized her exceptional abilities and encouraged her independent research even when it meant setting aside his own work.

In 1897, Marie gave birth to their first daughter, Irène. Despite the demands of motherhood, Marie continued her research, beginning the investigations into uranium rays that would lead to her Nobel Prize-winning discoveries.

The early years of Marie Curie’s life—from her childhood in occupied Poland through her student years in Paris—shaped the determination, resilience, and intellectual passion that would characterize her scientific career. The obstacles she overcame as a woman seeking education in a hostile political environment and a male-dominated field prepared her for the challenges ahead.

Career of Marie Curie

The Discovery of Radioactivity (1896-1898)

Marie Curie’s scientific career began with a decision to investigate a phenomenon that had captured the attention of the scientific world. In 1896, French physicist Henri Becquerel had discovered that uranium salts emitted rays that could penetrate opaque materials and expose photographic plates. While Becquerel was primarily interested in the phenomenon’s relationship to phosphorescence, Marie saw something more significant.

For her doctoral research, Marie chose to systematically study these “Becquerel rays.” Working in a converted storeroom at the School of Physics and Chemistry where Pierre taught, she developed innovative experimental techniques using an electrometer that Pierre and his brother Jacques had invented. This sensitive instrument allowed her to precisely measure the electrical conductivity of air exposed to uranium compounds.

Key Findings (1897-1898): - The emission of rays was an atomic property of uranium, not dependent on external conditions like light or temperature - The intensity of radiation was proportional to the amount of uranium in a compound - Thorium also emitted similar rays - Most significantly, certain uranium ores, particularly pitchblende from Joachimsthal (Jáchymov) in Bohemia, were more radioactive than pure uranium

This last observation was crucial. Marie hypothesized that pitchblende contained unknown elements more radioactive than uranium. Pierre, recognizing the importance of this discovery, abandoned his own research on crystals to join her investigation.

The Discovery of Polonium and Radium (1898)

In July 1898, the Curies announced their discovery of a new element, which Marie named “polonium” in honor of her native Poland. This element was 400 times more radioactive than uranium. However, they realized that polonium alone could not account for all the radioactivity in pitchblende.

In December 1898, they announced the existence of a second new element, which they named “radium” (from the Latin “radius,” meaning ray). Radium was dramatically radioactive—millions of times more so than uranium. However, the Curies had only established the existence of these elements chemically; they had not yet isolated them in pure form.

The Years of Processing Pitchblende (1899-1902)

To prove the existence of radium conclusively and determine its atomic weight, the Curies needed to isolate it in sufficient quantities. This required processing tons of pitchblende, which was expensive and labor-intensive.

The Austrian government, which operated the Joachimsthal uranium mines, donated several tons of pitchblende residue—the material left after uranium extraction—which the Curies received free of charge. However, they had to pay for transportation and processing costs.

Working Conditions: - The Curies worked in an abandoned shed that had previously been used as a medical school dissecting room - The shed had no ventilation, no proper heating, and a glass roof that leaked in the rain - Summer temperatures inside reached stifling levels - The Curies processed the ore manually, stirring massive vats with iron rods nearly their own height - Marie later wrote that the shed was “in certain ways, a miserable place, but in others, the most perfect of refuges”

Despite these primitive conditions, Marie and Pierre worked tirelessly. From 1899 to 1902, Marie processed over eight tons of pitchblende, eventually isolating one-tenth of a gram of pure radium chloride. In 1902, she determined radium’s atomic weight to be 225.93 (close to the modern value of 226).

The 1903 Nobel Prize in Physics

The Curies’ work attracted increasing attention from the scientific community. In 1903, Marie defended her doctoral thesis, “Research on Radioactive Substances,” receiving the highest possible rating. That same year, she and Pierre were nominated for the Nobel Prize in Physics, along with Henri Becquerel.

Initially, the Nobel Committee intended to honor only Pierre and Becquerel, but Pierre insisted that Marie be included. The 1903 Nobel Prize in Physics was awarded to “Becquerel, in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity” and “Pierre and Marie Curie, in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel.”

Marie became the first woman to win a Nobel Prize. The award brought international fame, but also challenges. The Curies were overwhelmed by publicity and declined to attend the Nobel ceremony in Stockholm, citing illness and previous commitments—though they did travel to Stockholm in 1905 to deliver their Nobel lectures.

Tragedy and New Responsibilities (1906)

On April 19, 1906, Pierre Curie was killed in a street accident. While crossing the Rue Dauphine in heavy rain, he slipped and fell under the wheels of a horse-drawn carriage, dying instantly from a skull fracture. Marie was devastated, losing not only her beloved husband but also her scientific partner.

The University of Paris faced an unprecedented situation: should they retain Marie as a professor? Her supporters argued that no one was better qualified to continue Pierre’s work. On May 13, 1906, the University appointed Marie to Pierre’s chair of physics, making her the first female professor in the university’s 650-year history.

Solo Scientific Leadership (1906-1911)

Following Pierre’s death, Marie assumed full leadership of their research program while raising their two daughters, Irène (born 1897) and Ève (born 1904). She continued her investigations into the properties of radium and other radioactive substances.

Major Research Directions: - Developing methods for isolating pure metallic radium - Studying the chemical properties of radioactive elements - Investigating the biological effects of radiation - Training the next generation of radiochemists

In 1910, Marie achieved a major scientific milestone: she successfully isolated pure metallic radium. This required electrolysis of molten radium chloride using a mercury cathode, followed by distillation of the mercury. This achievement, along with her ongoing research and her role in establishing international standards for radioactivity measurements, led to her second Nobel Prize.

The 1911 Nobel Prize in Chemistry

In 1911, Marie Curie was awarded the Nobel Prize in Chemistry “in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element.”

This made her: - The first person to win Nobel Prizes in two different scientific fields - The first person to win two Nobel Prizes in the sciences - The only woman to win Nobel Prizes in two different fields

The 1911 award was controversial. The French press launched a vicious campaign against her, fueled by xenophobia and misogyny. They attacked her for being a foreigner, accused her of being Jewish (she was not), and fabricated a scandal about an affair with physicist Paul Langevin. Despite the personal attacks, Marie traveled to Stockholm to accept the prize, delivering a powerful lecture on radium and radioactivity.

The Radium Institute and Scientific Administration (1910-1914)

In addition to her research, Marie devoted significant energy to establishing the Radium Institute (Institut du Radium) in Paris. The institute, which opened in 1914, consisted of: - The Curie Laboratory, directed by Marie, for physics and chemistry research - The Pasteur Laboratory, directed by Claudius Regaud, for biological and medical research

This dual structure reflected Marie’s vision of the peaceful applications of radioactivity, particularly in medicine. The Curie Institute remains a leading cancer research center today.

World War I and Mobile Radiology (1914-1919)

When World War I began in 1914, Marie put her research on hold to contribute to the war effort. She recognized that X-ray equipment could save countless lives by helping surgeons locate bullets and shrapnel in wounded soldiers.

Development of Mobile X-Ray Units: - Marie developed mobile radiological vehicles, which became known as “Little Curies” (petites Curies) - These units consisted of a vehicle fitted with X-ray equipment and a generator - She obtained funding from the Union of Women of France and other sources - Twenty mobile units were ultimately created and deployed to field hospitals

Personal Service: - Marie learned to drive and obtained a driver’s license - She personally operated mobile X-ray units at the front lines - She established 200 fixed radiological posts at field hospitals - She trained women as radiological technicians, including her daughter Irène - It is estimated that over one million wounded soldiers were examined using her X-ray units

For her wartime service, Marie was appointed Director of the Red Cross Radiology Service and received the French Military Medal. However, she refused to accept any honors, stating that her service was simply her duty.

Postwar Research and Recognition (1919-1934)

After the war, Marie returned to her research and administrative duties at the Radium Institute. She focused on: - Training radiochemists from around the world - Continuing research on radioactive substances and their applications - Advocating for international scientific cooperation - Raising funds for scientific research

The Curie Foundation (1920): - Marie established the Curie Foundation to fund the Radium Institute - She undertook a triumphant tour of the United States in 1921, where President Warren G. Harding presented her with a gram of radium collected by American women - A second American tour in 1929 secured funding for the Warsaw Radium Institute

International Recognition: - Member of the French Academy of Medicine (first woman) - Member of numerous international scientific societies - Honorary degrees from universities worldwide - The Curies’ daughter Irène married Frédéric Joliot in 1926, and the couple continued the family’s scientific legacy

Final Years (1930-1934)

In her later years, Marie’s health deteriorated due to radiation exposure. She suffered from cataracts, kidney problems, and chronic fatigue. Despite her declining health, she continued to work at the Radium Institute until shortly before her death.

In 1932, the Warsaw Radium Institute, which Marie had championed for years, finally opened. She attended the dedication, returning to her homeland as a celebrated scientist.

Marie Curie died on July 4, 1934, at a sanatorium in Passy, France, from aplastic anemia caused by radiation exposure. Her contributions to science and humanity remain immeasurable, and her legacy continues through the institutions she founded and the generations of scientists she inspired.

Major Achievements of Marie Curie

Nobel Prize in Physics (1903)

In 1903, Marie Curie became the first woman to receive a Nobel Prize, sharing the Physics award with her husband Pierre Curie and Henri Becquerel. The prize recognized: - Their joint research on radiation phenomena - The discovery that radioactivity was an atomic property - The identification of thorium as radioactive - The observation that certain uranium ores were more radioactive than uranium itself

This Nobel Prize was awarded despite significant resistance within the scientific establishment regarding women’s participation in science. Marie was initially excluded from the nomination, and Pierre had to insist on her inclusion.

Nobel Prize in Chemistry (1911)

Marie Curie’s second Nobel Prize made her the first person to win Nobel Prizes in two different scientific fields—a feat unmatched until Linus Pauling won in Chemistry (1954) and Peace (1962). The 1911 Chemistry Prize recognized: - The discovery of the elements radium and polonium - The isolation of pure metallic radium - The study of the nature and compounds of radium - Establishment of radioactivity as a field of chemistry

This achievement established Marie Curie as the preeminent radioactivity researcher in the world and secured her place in scientific history.

Discovery of Polonium (July 1898)

Working with pitchblende ore, Marie and Pierre Curie identified a new element significantly more radioactive than uranium. Marie named it “polonium” after her native Poland, making a political statement about Poland’s struggle for independence from Russian, Prussian, and Austrian partition.

Key Characteristics: - Atomic number: 84 - Approximately 400 times more radioactive than uranium - Extremely rare, with all isotopes being radioactive - No stable isotopes exist - Today used in anti-static devices and as an alpha particle source

Discovery of Radium (December 1898)

The Curies announced the discovery of a second new element, radium, which proved to be millions of times more radioactive than uranium. The name derives from the Latin “radius” (ray).

Scientific Significance: - Atomic number: 88 - First alkaline earth metal with radioactive properties - Emits alpha, beta, and gamma radiation - Half-life of the most stable isotope (Ra-226): 1,600 years - Produces a characteristic greenish glow in the dark

Radium became the foundation of Curie’s subsequent research and the basis for numerous medical and industrial applications.

Isolation of Pure Metallic Radium (1910)

After years of processing tons of pitchblende, Marie Curie successfully isolated pure metallic radium in 1910. This achievement required: - Electrolysis of molten radium chloride using a mercury cathode - Distillation of the mercury to obtain pure radium metal - Precise temperature control and specialized equipment

The isolation of radium metal allowed for accurate determination of its atomic weight (226) and provided material for medical and research applications.

Development of the Theory of Radioactivity

Marie Curie coined the term “radioactivité” (radioactivity) and developed foundational concepts that shaped the field:

Key Theoretical Contributions: - Radioactivity is an atomic property, not a molecular one - The intensity of radiation is proportional to the amount of radioactive material - Radioactive decay occurs independently of external physical or chemical conditions - The concept of half-life (developed further by Ernest Rutherford and Frederick Soddy)

Her systematic approach to studying radioactivity established the methodology for subsequent nuclear research.

Establishment of International Standards for Radioactivity

Marie Curie played a crucial role in establishing standardized measurements for radioactivity:

The Curie Unit: - Originally defined as the amount of radon in equilibrium with one gram of radium - Later redefined as 3.7 × 10¹⁰ disintegrations per second - Remained the standard unit of radioactivity until replaced by the becquerel (Bq) in 1975 - The curie (Ci) is still used in some medical and industrial applications

Founding of the Radium Institute (1914)

Marie Curie was instrumental in establishing the Radium Institute (Institut du Radium) in Paris, which opened in 1914. The institute comprised: - The Curie Laboratory for physics and chemistry research - The Pasteur Laboratory for biological and medical research

The institute became a world center for radioactivity research and cancer treatment. It continues today as the Curie Institute, one of the world’s leading cancer research centers.

Development of Mobile X-Ray Units (1914-1919)

During World War I, Marie Curie developed and deployed mobile radiological units:

Technical Innovation: - Twenty “Little Curies” (petites Curies) vehicles fitted with X-ray equipment - Self-contained units with generators and radiological equipment - Portable enough to reach front-line field hospitals

Impact: - Over 200 fixed radiological posts established - More than one million wounded soldiers examined - Women trained as radiological technicians - Significantly reduced mortality from battlefield injuries by enabling precise surgical intervention

Founding of the Warsaw Radium Institute (1932)

Marie Curie’s advocacy led to the establishment of the Radium Institute in Warsaw, which opened in 1932. Through two fundraising tours of the United States (1921 and 1929), she secured: - Financial support from American donors - A gram of radium for the Paris laboratory (1921) - Funding and a second gram of radium for the Warsaw institute (1929)

The Warsaw Radium Institute remains a major cancer research and treatment center in Poland.
