Marie Curie’s discoveries in radiation changed the world of science forever. She became one of the most important scientists in history, and her work still helps scientists and doctors today. She was the first person ever to win the Nobel Prize twice, and her discovery of the element radium helped us understand atoms better. Marie’s journey from a modest background to achieving great success shows how hard work and determination can lead to amazing accomplishments.
Marie Curie was born as Maria Salomee Sklodowska on November 7, 1867, in Warsaw, Poland. She was the youngest of five children in a family of educators. Her father, Vladislav, taught physics and math, and her mother, Bronislawa, ran a school for girls. Despite their dedication to education, the family faced financial struggles and lived at the school where Bronislawa worked. This meant little privacy for the children, who had to behave perfectly.
Bronislawa was worried about passing her tuberculosis to her children, so she avoided physical affection. When Maria, known as Manya, was five, the family moved to their own home but had to rent out rooms to make money. Manya shared a sofa in the dining room for sleeping and woke up early to help with breakfast.
From a young age, Manya was fascinated by the scientific instruments in her father’s study, especially the electroscope. She started school in 1874 and quickly became one of the top students. Although shy, she was often asked to recite poetry for guests, which she didn’t enjoy.
Life in Poland was tough under Russian rule, which banned the Polish language and history. These restrictions made many Poles, including Manya’s family, more determined to embrace their culture. Manya wanted to achieve great things and make her country proud.
Tragedy struck when Manya was eight; her sister Zofia died of typhus, and two years later, her mother passed away from tuberculosis. Despite her heartbreak, Manya excelled in school, supported by her father and siblings. She graduated high school at the top of her class in 1883 but soon fell ill and needed a year to recover with relatives in the countryside.
After recovering, Manya was eager to continue her education in science. However, Polish women were not allowed to attend the University of Warsaw. So, she and her sister Bronya decided to support each other financially. Bronya would study first, and then Manya would join her in Paris.
Manya worked as a governess for six years, teaching children and secretly educating local peasant children, which was illegal. She spent her free time studying and attended secret meetings of the “Floating University” to discuss banned scientific topics.
By 1891, Manya had saved enough money to join Bronya in Paris, where she changed her name to Marie.
In Paris, Marie attended the Sorbonne University, where she had to learn in a new language. Despite the challenges, she graduated in 1893 with a master’s degree in physics, earning top marks. She then pursued a second degree in mathematics.
While studying, Marie worked on research about the magnetism of steel. She needed a lab for her experiments, which led her to Pierre Curie, a famous physicist. They fell in love and married on July 26, 1895.
Marie continued her research while raising their first child, Irene. She became interested in Henri Becquerel’s discovery of uranium rays and chose this topic for her doctoral thesis.
In 1895, Wilhelm Roentgen discovered X-rays, which could pass through soft tissues but not bones. In 1896, Henri Becquerel found that uranium emitted rays naturally. Unlike many scientists, Marie Curie focused on studying these rays. She discovered that thorium also emitted similar rays.
In July 1898, Marie announced the discovery of a new element, which she named Polonium, after her homeland. She also introduced the term “radioactive” to describe the elements she studied. Later that year, she discovered another element, radium, which was even more radioactive.
Marie and Pierre worked hard to prove the existence of polonium and radium to the scientific community. They faced many challenges but eventually succeeded in producing these elements in pure forms and determining their atomic weights. Marie published many papers on her findings and completed her doctoral degree.
In June 1903, Marie became the first woman in Europe to earn a doctorate in science. However, both she and Pierre suffered from health problems due to radiation exposure. Despite the risks, radium was being used for its supposed health benefits, including cancer treatments.
In November 1903, the Curies received the Humphry Davy Medal, and a month later, they shared the Nobel Prize for Physics with Henri Becquerel. The prize money allowed them to hire a lab assistant and increased public interest in their work. However, Marie was too ill to attend the award ceremony in Sweden until 1905.
In 1904, Marie gave birth to a second daughter, Eve, and Pierre became a professor at the Sorbonne. Tragically, in April 1906, Pierre died in an accident. Heartbroken, Marie took his position at the Sorbonne, becoming the first female professor there.
Marie continued her research and helped establish the Radium Institute in Paris. By 1910, she had produced pure radium and published her comprehensive work, “Treatise on Radioactivity.” In 1911, she received a second Nobel Prize, this time in Chemistry, for her work on radium.
Despite her achievements, Marie faced challenges, including public scrutiny of her personal life and health issues from radiation exposure. She remained dedicated to her work, contributing to the war effort during World War I by organizing X-ray equipment for hospitals.
Marie Curie’s legacy continued through her daughter Irene, who, along with her husband, received the Nobel Prize for Chemistry in 1935. Marie herself passed away on July 4, 1934, from aplastic anemia, likely caused by her prolonged exposure to radiation.
In recognition of her groundbreaking contributions to science, Marie Curie was reburied in the Pantheon in Paris in 1995, becoming the first woman to receive this honor based on her own achievements.

**Marie Curie: A Scientific Pioneer**
Marie Curie’s groundbreaking discoveries in radiation transformed the world of science. She became one of the most significant figures in the field and her research continues to influence scientists and medical professionals today. Notably, she was the first individual, regardless of gender, to win the Nobel Prize twice. Her discovery of the element radium played a crucial role in unraveling the mysteries of atomic structure. Curie’s journey to success was remarkable, emerging from humble beginnings to demonstrate that hard work and determination can lead to extraordinary achievements.
**Early Life**
Maria Salomee Sklodowska was born on November 7, 1867, in Warsaw, Poland, as the fifth child of Vladislav and Bronislawa Sklodowska, both educators. Vladislav taught high school physics and mathematics, while Bronislawa, despite battling tuberculosis and raising five children, directed a private school for girls. Following Maria’s birth, she retired from teaching. The family faced financial difficulties due to poor investments, leading them to live at the school where Bronislawa worked. This situation meant little privacy for the children, who were expected to behave impeccably.
Bronislawa’s struggle with tuberculosis made her fearful of transmitting the illness to her children, resulting in a lack of physical affection. When Maria, affectionately known as Manya, turned five, the family managed to secure their own home, though they had to take in boarders to make ends meet. Manya shared a sofa in the dining room for sleeping and rose early to prepare breakfast.
From a young age, Manya was captivated by the scientific instruments in her father’s study, particularly the electroscope. She began school in 1874 at the age of six, quickly establishing herself as one of the brightest students. Despite her shyness, she was often chosen to recite poetry for guests, a task she disliked.
Life in Poland during the late 19th century was challenging, particularly under Russian rule, which prohibited the use of the Polish language and the study of Polish history. These restrictions, however, only strengthened the resolve of many Poles, including Manya’s family, to embrace their heritage. Manya aspired to achieve great things and bring honor to her country.
Tragedy struck when Manya was eight; her older sister Zofia succumbed to typhus fever, followed by the death of their mother from tuberculosis two years later. The loss left Manya heartbroken, yet she maintained excellent grades in school, buoyed by the support of her father and siblings. In 1883, she graduated high school at the top of her class but soon fell ill, necessitating a year of recovery with relatives in the countryside.
**Pursuing Education**
Upon her return, Manya was determined to continue her education in the sciences. However, the Russian government barred Polish women from attending the University of Warsaw. In response, she and her sister Bronya devised a plan to pool their resources, allowing Bronya to study first, followed by Manya at the University of Paris.
Manya spent six years working as a governess for a wealthy family, during which time she tutored their children and taught local peasant children to read and write, an illegal act that could have led to severe punishment. She dedicated her free time to studying and attended clandestine meetings of the “Floating University,” where banned scientific works were discussed.
After her employment with the Zorawski family ended, Manya returned to Warsaw and began working for another family. One of her cousins managed a laboratory where Polish students could study science. By 1891, Manya had saved enough money to join Bronya in Paris, where she adopted the name Marie.
**Academic Achievements**
In Paris, Marie attended the Sorbonne University, where she faced the challenges of learning in a foreign language. Despite these obstacles, she graduated in 1893 with a master’s degree in physics, earning top marks in her class. She then pursued a second degree in mathematics.
While studying, Marie took a job researching the magnetism of various types of steel. To conduct her experiments, she needed access to a laboratory, which led her to Pierre Curie, a renowned physicist. Their professional relationship quickly blossomed into romance, and they married on July 26, 1895.
Marie continued her research while raising their first child, Irene. She became fascinated by the work of Henri Becquerel, who had discovered uranium rays, and chose this topic for her doctoral thesis.
**Groundbreaking Discoveries**
In 1895, Wilhelm Roentgen discovered X-rays, which could penetrate soft tissues but not dense materials like bone. In 1896, Henri Becquerel found that uranium emitted rays naturally. Unlike many scientists of the time, Marie Curie dedicated herself to studying these rays, systematically investigating other elements and discovering that thorium also emitted similar rays.
In July 1898, after extensive research, Marie announced the discovery of a new element, which she named Polonium, in honor of her homeland. She also coined the term “radioactive” to describe the elements she studied. Later that year, she discovered another element, radium, which was even more radioactive.
Marie and Pierre faced the challenge of proving the existence of polonium and radium to the scientific community. They worked tirelessly to produce these elements in their purest forms and to establish their atomic weights. Despite the difficulties, Marie published numerous papers on her findings and completed her doctoral degree.
**Recognition and Challenges**
In June 1903, Marie became the first woman in Europe to earn a doctorate in science. However, as their fame grew, both she and Pierre experienced declining health due to radiation exposure. Despite the risks, radium was being promoted for its supposed health benefits, leading to its use in cancer treatments.
In November 1903, the Curies received the Humphry Davy Medal, followed by the Nobel Prize for Physics a month later, shared with Henri Becquerel. The prize money allowed them to hire a lab assistant and increased public interest in their work. However, Marie was too ill to attend the award ceremony in Sweden until 1905.
In 1904, Marie gave birth to a second daughter, Eve, and Pierre was appointed a professor at the Sorbonne. Their lives took a tragic turn in April 1906 when Pierre was killed in an accident. Devastated, Marie accepted his position at the Sorbonne, becoming the first female professor there.
**Continued Contributions**
Marie continued her research and was instrumental in establishing the Radium Institute in Paris. By 1910, she had produced pure radium and published her comprehensive work, “Treatise on Radioactivity.” In 1911, she received a second Nobel Prize, this time in Chemistry, for her work on radium.
Despite her achievements, Marie faced challenges, including public scrutiny of her personal life and health issues stemming from her exposure to radiation. Nevertheless, she remained dedicated to her work, contributing to the war effort during World War I by organizing X-ray equipment for hospitals.
Marie Curie’s legacy continued through her daughter Irene, who, along with her husband, received the Nobel Prize for Chemistry in 1935. Marie herself passed away on July 4, 1934, from aplastic anemia, likely caused by her prolonged exposure to radiation.
