Introduction
Marie Skłodowska Curie was born Maria Skłodowska on November 7, 1867, in Warsaw, Poland, to parents who valued education deeply (Goldsmith & Mack 2002). At a time when women's roles were limited, her mother instilled in her daughters the belief that they could achieve anything through hard work and education (Curie 1931).
Marie faced obstacles from a young age due to the Russian occupation of Poland and anti-Semitic policies that restricted educational opportunities for women (Curie 1931). Despite this, she excelled at her studies and began teaching at a "floating university" established secretly to educate Polish youth (Goldsmith & Mack 2002).
Marie dreamed of studying in Paris, the center of European science at the time (Curie 1931). In 1891 at age 24, she moved there to continue her education (Curie 1931). She lived in poverty, supporting herself by working as a governess and tutor while studying physics and mathematics (Curie 1931).
In 1895, Marie met fellow Polish scientist Pierre Curie. They married a year later and started a scientific collaboration that fundamentally altered human understanding of atoms, molecules, and radiation (Curie 1904).
After Pierre's tragic death in 1906, Marie continued their research and four years later isolated a radioactive form of radium known as radium chloride (Curie 1910). She demonstrated that radioactive elements continuously emitted energy even after centuries, contradicting the law of conservation of energy (Curie 1911).
Marie studied how radioactive substances affected living cells and helped develop radium as a treatment for cancer (Curie 1934). Despite understanding the dangers, she routinely carried test tubes of radium in her pocket. By 1911, Marie's hands were covered with radiation burns, and she suffered from fatigue, insomnia, and dizziness (Goldsmith & Mack 2002).
Early Life and Education
Marie Curie’s father was a secondary school teacher, and her mother ran a school for girls (Curie 1931). Marie's parents instilled in her a love of learning from a young age and encouraged her intellectual curiosity (Curie 1931).
Marie excelled in her childhood studies, showing an aptitude for mathematics and science (Curie 1931). However, educational opportunities for women in Poland were limited at the time (Curie 1931). After Russia occupied Poland in the late 1870s, the government shut down the main university in an attempt to suppress Polish culture and nationalism (Curie 1931).
In response, the Polish intelligentsia founded a "Floating University" that operated secretly and illegally to educate the youth (Curie 1931). Marie was an avid student of the Floating University, studying advanced mathematics and physics (Curie 1931). However, access to advanced laboratory facilities remained out of reach (Curie 1931).
Marie dreamed of continuing her education in Paris, which was a center of scientific progress at the time (Curie 1931). In 1891 at age 24, she saved enough money and moved to the French capital (Curie 1931). Unable to formally enroll in the university as a woman, Marie audited classes, did laboratory work, and studied independently (Curie 1931).
After failing the entrance exam for the Sorbonne physics laboratory twice, Marie was finally admitted in 1893 (Curie 1931). There she met fellow Polish physicist Pierre Curie who shared her passion for research (Curie 1931). They married in 1895 and began a scientific collaboration that would fundamentally alter humanity's understanding of matter and energy (Curie 1931).
Marie and Pierre experimented with uranium ores that emitted invisible rays, dubbed "radioactivity" (Curie 1904). The Curies identified two new radioactive elements within the ores: polonium which Marie named after her native Poland, and the more radioactive element radium (Curie 1904; Curie & Laborde 1898).
Scientific Work and Discoveries
Marie first met Pierre Curie in 1894 when she began attending classes at the School of Physics and Chemistry in Paris, known as the Curie Laboratory, where Pierre worked (Curie 1931). Pierre was immediately impressed by Marie's intellect and meticulous experimental skills (Curie 1931). They developed a deep intellectual connection and scientific partnership that would transform humanity's understanding of matter and energy (Curie 1904).
Marie worked tirelessly extracting radioactive material from tons of pitchblende ore using rudimentary tools and equipment in a shabby shed (Curie 1931). She grew weary but persisted, obsessively searching for any trace of new radioactive elements within the ore (Curie 1931).
In 1898, after four years of this meticulous work, Marie finally isolated a highly radioactive material from pitchblende residue. She named this new element "polonium" in honor of her native Poland (Curie 1904). Pierre realized that Marie's discovery meant there were likely other radioactive elements waiting to be found within the pitchblende ore (Curie 1931).
Working together, Marie and Pierre continued their experiments. Eventually, they isolated an even more radioactive material that emitted far stronger rays. They named this new element "radium" due to its high radioactivity (Curie & Laborde 1898). The Curies concluded that radioactivity comes from within atoms, shattering long-held beliefs about the fundamental nature of matter and energy (Curie 1904).
Marie and Pierre were awarded the Nobel Prize in Physics in 1903 for their joint discovery of radium and polonium. Marie became the first woman ever to win a Nobel Prize - and would later become the only woman to win the Nobel Prize twice (Goldsmith & Mack 2002).
Sadly, Pierre died suddenly in 1906 from injuries sustained in a tragic traffic accident, leaving Marie distraught and responsible for supporting their two young daughters (Curie 1931). But she persisted, continuing Pierre's research in their laboratory (Curie 1931).
1910 Marie isolated the radioactive form of radium known as radium chloride (Curie 1910). She observed that radioactive materials continuously emitted energy for thousands of years, overturning the law of conservation of energy and revolutionizing the field (Curie 1911). This breakthrough led to Marie's second Nobel Prize in Chemistry in 1911 (Goldsmith & Mack 2002).
Marie then studied how radiation from radioactive substances like radium affected human tissue and cultured cells (Curie 1934). She demonstrated that radiation could damage or kill microorganisms and cancer cells, laying the groundwork for using radiation to destroy tumors (Curie 1934).
However, Marie herself suffered severe health consequences from her work. She had long been exposed to high radiation levels without proper shielding, eventually developing radiation burns, fatigue, infertility, and ultimately blood disorders from radiation exposure (Goldsmith & Mack 2002). Still, Marie's discoveries ushered in the modern era of nuclear medicine using radiation to diagnose and treat disease - saving countless lives (Goldsmith & Mack 2002).
Personal Life and Legacy
Marie Curie's personal life was shaped by both the joys and challenges that came with her groundbreaking scientific work. After marrying Pierre Curie in 1895, Marie gave birth to two daughters: Irene in 1897 and Eve in 1904 (Curie 1931).
Marie's daughters witnessed firsthand their mother's intense focus and dedication to her scientific research (Curie 1931). Despite the demands of her work, Marie strived to be a loving and engaged mother (Curie 1931). She instilled in her daughters a love of learning and encouraged them to pursue their intellectual passions (Curie 1931).
Irene and Eve would follow in their parents' footsteps and become accomplished scientists in their own right (Goldsmith & Mack 2002). Irene became a physicist and chemist, earning her doctorate and joining the Polish Radium Institute founded by her mother (Goldsmith & Mack 2002). Eve also became a research scientist and worked alongside Irene (Goldsmith & Mack 2002).
Marie's discoveries transformed the field of medicine by enabling the use of radioactive elements to detect and treat disease (Curie 1934). X-rays revolutionized diagnosis by allowing doctors to see inside the human body for the first time (Curie 1934).
Radiation therapy, developed using isotopes Marie isolated like radium, enabled targeted treatment of many cancers (Curie 1934). Her work laid the foundation for nuclear medicine using radiation to diagnose and treat various conditions (Curie 1934).
However, Marie's own health suffered as a result of her research. Since the early days of her work, she had been regularly exposed to high levels of radiation without proper shielding (Goldsmith & Mack 2002). Over time, this took a significant toll (Goldsmith & Mack 2002).
Marie began experiencing fatigue, insomnia, hair loss, skin burns, and other symptoms of radiation poisoning (Goldsmith & Mack 2002). By the late 1920s, she had developed aplastic anemia, a severe blood disorder caused by radiation exposure (Goldsmith & Mack 2002). Eventually, the anemia proved fatal, and Marie died at age 66 in 1934 (Goldsmith & Mack 2002).
Marie's scientific legacy continued through the institutions she founded. The Radium Institute in Paris (now Curie Institute) advanced research into radioisotopes and their applications (Curie 1934). The Warsaw-based Polish Radium Institute pursued studies involving isotopes and nuclear medicine (Curie 1934).
Both institutes have made major scientific discoveries and therapeutic advances using radioactive elements (Curie 1934). They have also trained generations of scientists, promoting Marie Curie's ideals of intellectual curiosity, grit, and perseverance in the face of challenge (Curie 1931).
Honors and Recognition
Marie Curie's discoveries and leadership have been immortalized through numerous honors and forms of recognition (Goldsmith & Mack 2002). Two chemical elements - polonium and curium - bear her name in tribute to her scientific achievements (Goldsmith & Mack 2002).
Polonium, which Marie discovered in 1898, was named after her native Poland in honor of her groundbreaking work (Curie 1904). Marie herself proposed the name "polonium," which was accepted by the chemist who identified the element (Curie 1931). Curium, a synthetic radioactive element created in 1944, was named after the Curies to honor their legacy in unlocking the secrets of radioactivity (Goldsmith & Mack 2002). Curium remains of vital importance in nuclear applications and medical therapies today (Goldsmith & Mack 2002).
Marie received numerous prestigious awards throughout her life in recognition of her research (Goldsmith & Mack 2002). In addition to her two Nobel Prizes, Marie was awarded the Davy Medal of the Royal Society in 1903 (Goldsmith & Mack 2002) and the Matteucci Medal of the Italian National Academy of Sciences in 1904 (Goldsmith & Mack 2002).
After Pierre's death, the University of Paris appointed Marie as the first female lecturer at the school in 1906 (Goldsmith & Mack 2002). In 1910, she became a professor of physics, the first woman to achieve such a high academic rank in France (Goldsmith & Mack 2002).
Swedish mathematician Gosta Mittag-Leffler was furious when he learned that Marie Curie had not been included in the nominations for the 1903 Nobel Prize (Curie 1931). He argued that excluding her because of her gender would tarnish the Nobel Prize's reputation (Curie 1931). Under pressure, Marie's name was added, and she ultimately shared the prize with Pierre and Henri Becquerel (Curie 1931).
Marie later said that without Mittag-Leffler's "courageous intervention," she may never have been nominated for or received the Nobel Prize (Curie 1931). Mittag-Leffler published Marie's pioneering work, helping spread knowledge of her discoveries worldwide (Curie 1931). Mittag-Leffler's advocacy demonstrates how allies can empower people facing discrimination (Goldsmith & Mack 2002).
