Irène Joliot-Curie – For the Joy of Science

In 1925, Irène Curie walked into an auditorium of 1000 people to defend her dissertation. This was big news because she was the daughter of two time Nobel Prize winner Marie Curie. The pressure could have been enormous, but as usual Irène was calm, confident, and dressed unfashionably! From an early age, Irène had dealt with her parent’s fame both positive, such as when at the age of six she calmly told the reporter who came to the house that her Nobel Prize winning parents were at the laboratory, and negative when a classmate handed her a newspaper article about her mother’s affair with Paul Langevin. She had come to see fame as something external and of no real importance. She didn’t pursue her research for fame, but for the sheer joy of the science itself.

At first glance, Irène was a quiet, shy child, some might even say somber, but as time would show, she just had little energy or attention for things that in her mind didn’t matter or that bored her. Born in September of 1897, her parents Pierre and Marie Curie were in the midst of their most intense period of research. In spite of this, she was a wanted and welcome addition to the family. Limited time and resources, however, did mean that the young parents needed help, and this came in the form of Pierre’s father, Eugene Curie. Pierre’s mother died shortly after Irène was born, so Eugene moved into the house to take care of her.

Eugene was a more openly affectionate person than either Marie or Pierre, and gave Irène, and later her sister Eve, born in Paris in 1904, much of their emotional foundation. Irène later said that many of her values and beliefs about religion and politics came from her grandfather rather than her mother. When Pierre died in 1906, Marie was so distraught that she wouldn’t let his name be spoken around her. Eugene helped the girls by talking to them and teaching them about their father. After Eugene died in 1910, Marie, Irène, and Eve became much closer and remained close for their entire lives.

In spite of a more reticent personality, Marie and Eugene agreed on many things. Because of his unique personality and abilities, Pierre’s parents had home-schooled him, and Marie felt that the same approach would be better for Irène. To supplement the public school, she organized a cooperative among other scientists and academics to provide classes in their homes for their children. The subjects ranged from mathematics and science, to literature and art. Emphasis was put on creativity, play, and self-expression. Other physical and practical activities weren’t neglected either. Marie made sure the girls learned to cook, knit, and sew, as well as to swim, bicycle, and ride horseback. Irène was especially athletic. She took long backpacking trips during the summer, frequently swam the Australian crawl in the Seine, and could dance until early in the morning. It didn’t phase her that backpacking and the Australian crawl were considered men’s sports.

From an early age it was clear that Irène was very much like her father. Among her friends she was calm and relaxed, but she was less comfortable with strangers, rarely smiling in public. Her thought process was much like his as well, not as quick as Eve, but a deep analytical thinker. It was also clear that Irène would be good at science. After the cooperative ended, Marie continued to teach Irène mathematics to give her the foundation she needed, even sending problems back and forth in the mail when Marie was away at conferences. After a couple more years in public school, Irène finally entered the Sorbonne to study science.

In 1914, World War I interrupted Irène’s studies. Marie had written to Irène saying that she hoped they could both be of service, so when her mother developed a mobile x-ray unit, she went into the field to help operate and maintain them. But to say that she helped her mother is to greatly understate the situation. The need was so great that they worked independently of each other. Irène went to the front to set up, repair, and operate the units. Often they were used during surgery to help locate shrapnel in the body. When she wasn’t at the front trying to convince experienced military surgeons that a teenaged girl knew more about x-rays and geometry than they did, she was training other technicians. In spite of spending her eighteenth birthday alone at the front, she seems to have handled this time with composure and a confidence that is rare, although her mother never doubted her. Irène later said, “My mother had no more doubts about me than she had about herself.”

Once the war was over, Irène returned to the Radium Institute, run by Marie, to continue her research and study. Here in 1924, just before receiving her doctorate, Irène met Frédéric Joliot. Two years her junior, Frédéric was outgoing and charming. According to their daughter Hélène, they were “opposites in everything.” He was from a big family, had a wide variety of interests, and was much more sociable than Irène, but they shared some very important things. They loved outdoor sports, had similar political views, and loved science. When they were married in October of 1926, they had lunch at Marie’s apartment and went back to work.

Irène and Frédéric worked together for the rest of their lives and collaborated on their most important work. As with other creative teams, their approaches were very different. He moved quickly from one idea to the next, taking creative leaps, while Irène was slower in her thought process, but moved steadily toward logical conclusions. Several times they made important discoveries, but didn’t interpret the information correctly. One of these experiments was similar to that done by Otto Hahn which was interpreted by Lise Meitner leading to Hahn’s Nobel Prize. Finally, in 1935, Irène and Frédéric Joliet-Curie received a Nobel Prize in Chemistry for the discovery of artificial radioactivity.

In the intervening years, Irène had given birth to a daughter, Hélène in 1927, and to a son Pierre in 1932. She loved being a mother and in many ways was traditional, but she maintained her career. Although Marie died in 1934, she had lived long enough to see the experimental results that she knew would ensure her daughter a Nobel Prize. So in 1935, their lives were marred by only one thing – the growing Fascist threat in Europe.

After 1935, Irène and Frédéric no longer collaborated directly in their work. Frédéric took a position at the Collège de France where he worked in nuclear physics, building a cyclotron and raising funds for scientific research. In this position he became very powerful and contributed greatly to France’s ability to produce nuclear energy. Irène became a professor at the University of Paris, but continued as the research director at the Radium Institute. She also got involved in politics and joined several women’s rights organizations.

When the Popular Front, an anti-Fascist coalition, was elected in 1936, Irène was offered and accepted the position of under-secretary of scientific research, making her one of the first women cabinet members in France. As the war progressed, Frédéric joined the resistance and eventually, the Communist party because it was the most active anti-Fascist group in the country. Irène’s activity, however, declined. For almost twenty years she had suffered from tuberculosis and was having to take more and more time away from work and in the Alps on the “rest” cure. Finally, Frédéric, as head of his resistance organization, was forced to go underground and arranged to have Irène and the children smuggled into Switzerland, on June 6, 1944.

After the war, Frédéric was considered a hero, and appointed head of France’s Atomic Energy Commission with Irène as a commissioner. Irène was able to obtain streptomycin to cure her tuberculosis and continue her work for women’s rights and as director of the Radium Institute. For a while things were good, but by 1950, the Cold War was gaining ground and anti-communist sentiments were growing. Both Irène and Frédéric found themselves out of favor and for the first time outside the scientific community. Frédéric was fired from the Commission, and unable to obtain other scientific work, began to work for peace organizations. Irène was at least able to continue her work at the Institute, but the years of work had taken another toll.

Like Pierre and Marie before them, Irène and Frédéric were both suffering from the effects of prolonged exposure to radiation. Their health declined steadily in the 1950s. Even though Marie continued to work and worry about Frédéric’s health, she was finally unable to ignore the effects. On a trip to the Alps, Irène became ill. Returning to Paris, she checked in to the hospital and on March 17, 1856, Irène died of leukemia. Frédéric was too ill to see her for more than a few minutes. He died two years later. By this time the worst of the red scare was past and they were both honored with national funerals. They had spent their lives doing what they loved.

“I discovered in this girl whom other people regarded somewhat as a block of ice, an extraordinary person, sensitive and poetic, who in many ways gave the impression of being a living replica of what her father had been. I had read much about Pierre Curie. I had heard teachers who had known him talking about him and I rediscovered in his daughter the same purity, his good sense, his humility.” ~ Frédéric Joliot-Curie about Irène

Lise Meitner – Nobel Prize Denied

Lise Meitner in 1906

Lise Meitner in 1906 (source)

In December of 1938, Lise Meitner received a letter from colleagues in Germany explaining their latest experimental results and questioning what these results could mean. For almost 30 years Lise had worked with Otto Hahn, and later Fritz Strassman, performing experiments related to radioactivity. Although she had begun as Hahn’s assistant without pay, their relationship had evolved to the point where she was the recognized expert in matters related to physics; Hahn was a chemist.

Lise’s nephew Otto Frisch was visiting for the holidays and together they discussed the letter she received. Researchers working on radioactivity had known for some time that one element could change into another, such as radium to polonium in Marie Curie’s experiments. But recently several researchers, when bombarding uranium with neutrons, had been finding elements with smaller atomic weights, almost half the atomic weight of uranium. At the time no one believed that the nucleus of an atom could be split. Hahn and Strassman’s research repeated this result. Meitner realized that this was exactly what was happening and that the power that would result from a chain reaction would be immense. Together she and Frisch worked out the mathematics and she conveyed the information to Neils Bohr who was on his way to the United States for a conference. And the rest as they say is history.

I knew this basic scenario when I began to read about Lise Meitner, but as usual there is more to the story. Lise Meitner was born in Vienna in 1878, the third of eight children born to Philipp and Hedwig Meitner. Philipp, a freethinker and humanist, was one of the first to become a lawyer in Vienna after the professions were opened up to Jews. Hedwig was an accomplished pianist. Their home was filled with music and interesting people. When asked about her childhood Lise remembered all “the unusual goodness of my parents, and the extraordinarily stimulating intellectual atmosphere in which my brothers and sisters and I grew up.”

The educational opportunities available to Lise were similar to those available to Emmy Noether in Germany; they consisted primarily of training that would enable a girl to become a good wife and mother. Public education ended for girls at age 14 and they were not admitted to the universities, so there were no secondary preparatory schools for girls. Lise wanted to study physics and her father agreed to pay for tutors if she would complete a teacher training course first. There were few employment opportunities for men or women in physics, and since Lise had shown little interest in marrying this would give her a way to support herself.

Lise studied constantly and by 1901 when Vienna allowed women to enter the university she was able to pass the entrance examinations at the age of 23. Over the next six years, she completed her doctorate in physics and published several papers related primarily to radioactivity. She also spent a year practice teaching French in a girl’s school to ensure a backup means of support. She was fortunate to study under Ludwig Boltzmann in Vienna. He was an inspiring lecturer and a proponent of atomic theory when it was still controversial. Unfortunately, he died in 1906, but he had inspired Lise to continue studying physics if at all possible.

Looking for a direction to go in her study, Lise applied to work with Marie Curie, but was rejected. In 1907, Max Planck in Berlin agreed to allow her to audit his lectures. Although Planck’s experiences with women in the sciences had been good, he wasn’t really in favor of it. He did, however, welcome Lise into his home where he had twin daughters her age. Here she would find friendship and music during her stay in Germany. One of the friends she made through Planck was Otto Hahn. Hahn was a chemist working on radiochemistry at Emil Fischer’s Chemistry Institute. He needed a physicist to work with and proposed this idea to Lise; she accepted and they began what would be a very productive working relationship.

Under conditions that will sound familiar if you’ve read my previous posts, Lise began working without pay as Hahn’s assistant at the Fischer Institute. The catch – Fischer didn’t allow women in his facility. (One reason was that he had the idea that women’s hair styles were a fire hazard.) He did “compromise” and let her work in a basement room which had been a carpentry shop and had an outside entrance; she was not allowed upstairs and had to use a toilet down the street. This meant that she couldn’t attend lectures or observe Hahn’s experiments. In spite of this, they published several papers together. In 1908, German universities were opened to women and she was finally allowed to enter the building (and they installed a toilet for women!)

Hahn and Meitner worked well together. At first she was deferential to him, but over time she became the recognized leader of their partnership, in the area of physics. In 1912, they moved to the Kaiser Wilhelm Institute for Chemistry, a facility funded by German industrialists. She was still unpaid, but Planck was able to get her an assistant position grading papers at the University with a small salary. Because she was developing a good reputation, the University of Prague offered her a position of associate professor with the possibility for advancement. As a result the Institute finally decided to give her a salary, although at the time still less than Hahn, so she decided to remain in Germany. Finally in 1917, Meitner became the head of her own department of radiophysics at the Institute.

The 1920s and 30s were a “golden era” in physics and Meitner was a prominent part of that. Einstein referred to her as “our Madame Curie” and Wolfgang Paul, a 1989 Nobel Prize winner considered her “a really great scientist” and the superior of Hahn. During this time she and Hahn primarily worked apart, but in 1934, she began experiments that required the expertise of a chemist and Hahn agreed to collaborate again. A number of scientists, including Meitner and Hahn, Enrico Fermi, and Irene Joliot-Curie, began their experimentation with uranium.

Unfortunately, Lise wasn’t competing only with other physicists. In 1933, Jews such as Emmy Noether were expelled from university positions. Although Jewish, Meitner had been baptized a protestant and had an Austrian passport. This, and the fact that the Wilhelm Institute was not a government facility, gave her some protection. This ended however, when Hitler invaded Austria and the Institute was under increasing pressure even from within by Nazi-sympathizers. She now found herself with an invalid passport and a tenuous job. Friends abroad worked feverishly to find her a position and finally in 1938, she slipped over the border into the Netherlands with only a few possessions and moved on to take a position in Sweden.

Hahn and Meitner continued consulting via letter with one secret meeting in Copenhagen in November to plan experiments. These experiments resulted in the letter of December 1938, which she discussed with Otto Frisch. In the letter, Hahn does not draw conclusions and in fact questions the results. Meitner trusted Hahn’s results, he was an excellent chemist, and accepted the obvious conclusion, and that the atom had split. Hahn published his experimental results without drawing conclusions and without crediting Meitner, a move which she understood; he couldn’t officially collaborate with a Jew. She and Frisch published their conclusions soon after along with corroborating experimental results by Frisch. In their paper they coined the term fission to describe what had happened.

Meitner’s recognition of the principle of fission was momentous. When Frisch described the theory to Bohr, he slapped his head and said “Oh what idiots we’ve been.” Understanding the experimental results and knowing that the German’s had the information prompted action within the physics community and then the Allied governments. Meitner was eventually offered a position with the Manhattan Project, which she refused having no desire to work on a bomb.

Everyone in the physics community recognized what Lise had done. Although she wasn’t there for the final experimental results, she had originated the project, gathered the team, worked on it for almost 4 years, and interpreted the final results. Nevertheless, only months after publication Hahn began denying that Meitner had been an important part of the discovery at all. Then in 1944, the Nobel Committee voted secretly to give the Nobel Prize for Chemistry to Hahn, and Hahn alone, for the discovery of nuclear fission. No one disputed that Hahn deserved it, but everyone in the physics community knew that Meitner deserved a Nobel Prize as well.

Lise Meitner continued to work in Sweden until her retirement, when she moved to England to be near her relatives. In spite of the hurt of Hahn’s betrayal, and Lise’s intense criticism of the scientists who had collaborated with the Nazis, they remained friends. Her family didn’t inform her of Otto Hahn’s death in July of 1968 because of her frail condition, and she died later that year in October. Although denied the Nobel Prize, she led a very fruitful life with recognition from her peers and the love of family and friends. Her nephew Otto Frisch had her tombstone inscribed with the statement, “Lise Meitner: a physicist who never lost her humanity.”

Madame Curie – Part 2

To read about Marie’s early life click here.

Marie and Pierre Curie were both people who preferred to stay out of the limelight. As their fame grew, Marie probably adjusted to the attention better than Pierre did, but doing the work of science was foremost for both of them. Pierre still had a low level position in one of the less prestigious schools in Paris even though he had friends who worked to try to get him a position at the Sorbonne. Marie had finished her work on magnetism and began to look around for a topic for her doctoral thesis. They took a small apartment, Pierre took on more tutoring work and Marie got her teaching certification. Their income was small, but they could make it.

During this time, there was a series of discoveries which would set the stage for the work which would bring Marie Curie her fame. Conrad Röntgen discovered X-rays. The exact nature of this radiating energy was unknown, but a connection was hypothesized between X-rays and phosphorescence. Henri Becquerel, with an interest in phosphorescence, experimented to determine whether or not other minerals known to be florescent produced X-rays. After testing many different minerals, the only one which exhibited a similar type of radiating energy was uranium.

The discovery of X-rays created quite a stir, particularly with its implications for medicine, so of course the Curie’s followed the related research. Marie thought that uranium and this radiating energy were of interest and decided to investigate further. By examining ore samples containing uranium, she determined that the amount of radiation was directly related to the amount of uranium in the sample. It wasn’t affected by other factors such as temperature or other elements contained in the sample. This led her to hypothesize that the radiation was a characteristic of the atom itself.

One of the minerals that she investigated was pitchblende. Here she measured much higher levels of radiation than could be accounted for by uranium. She concluded that there must be additional elements within pitchblende that also exhibited this property of radiating energy and began the long and tedious process of isolating and identifying them. She coined the term radioactivity and established the science that would be used to analyze it.

It is important to remember that other scientists were actively involved in similar investigations. Becquerel had in fact discovered, and maybe more importantly, published the concept of radioactivity first. In Marie’s experiments she discovered that the element thorium was radioactive, but Gerhard Schmidt in Germany had discovered the same thing and published it earlier. Marie knew of the importance of announcing and publishing her work in a timely fashion. Since, neither she nor Pierre were members of the French Academy of Science, her former professor Gabriel Lippman presented her first paper on the subject for her in 1898.

It took about four years for Marie to complete her work. She isolated two radioactive elements in pitchblende: polonium and radium. At some point, Pierre put his work aside and began to work with her, as did other scientists and students. Much of the work, especially at the beginning, required back breaking effort. As it turns out, they had to process from 6- 7 tons of pitchblende to get a miniscule amount of radium. Radium is the element that caught the imagination of the world and would be used in things from paint on watch dials to “health” drinks, much to the detriment of those that came in close contact with it.

During this period of time, Marie gave birth to their first daughter, Irene, in 1897. It was, of course, expected that a woman would take care of everything related to the home. When Marie and Pierre were married, their home and lives were simple. It is said that they only had two chairs at their table to discourage visitors from staying. In the evening, they would companionably read physics together. They had a shared obsession with science that overshadowed everything else. When Irene was born this changed dramatically.

Marie and Pierre with Irene c. 1902 (source)

Marie and Pierre with Irene c. 1902 (source)


Marie went back to her work, but would have to rush home to nurse Irene. She didn’t have enough milk and had to hire a wet nurse. With two nurses to care for the baby, their meager income was stretched even more. With the hard physical work she was doing, the increased expenses, and the feeling of failure at not being able to nurse her baby, the stress took its toll on Marie’s health. Pierre’s father came to the rescue. Dr. Eugene Curie was the physician who had delivered Irene. During the same month, his wife, Pierre’s mother died of breast cancer. So, at the beginning of 1898, Dr. Curie moved in with Marie and Pierre to care for Irene.

Dr. Curie was a godsend. He was a warm, expressive man who Irene and later Eve would remember fondly. He is probably responsible for meeting most of their emotional needs. There is no doubt that Marie loved her children, but she and Pierre were in many ways lost in their scientific world. And after Pierre died in 1906, Marie would close herself off emotionally, preventing them from even mentioning Pierre’s name in her presence.

Pierre had been denied the acclaim in France that he had received internationally, in part due to his unconventional background, and Marie faced these kinds of prejudices as well because she was a woman. By 1902, she had isolated enough radium to determine its place on the periodic table and to satisfy the chemists that it was indeed a new element. She wrote her thesis and received her doctorate and in 1903, Marie, Pierre, and Henri Becquerel were nominated for and received the Nobel Prize in physics.

It wasn’t quite that simple though. The Nobel Prizes were first given beginning in 1901. That first year, and again in 1902, Charles Bouchard nominated all three of them. Other people were chosen both years. Then in 1903 four influential scientists, including Gabriel Lippman, Marie’s former professor whom she considered a friend, nominated Henri Becquerel and Pierre Curie for the physics prize with no mention of Marie. Magnus Gustaf Mittag-Leffler a respected Swedish mathematician who was on the nominating committee told Pierre of the nomination. Pierre wrote him that he would not accept the prize unless Marie was included. He approached the committee with this letter, and with the support of Charles Bouchard, the nomination was changed to include Marie.

(Mittag Leffler believed that women were under appreciated in the sciences. He was also the person responsible for raising the private funds to support the appointment of Sonya Kovalevsky to a position of full professor in mathematics at his university in Sweden. She was the first woman to become a professor of mathematics and Marie Curie the first woman to become a Nobel Prize winner. Thank you Professor Leffler!)

Life changed after the Nobel Prize. Although, the Curie’s had not patented their process for extracting radium, they did receive some income from it due to its immense popularity, but probably not enough to make up for the time they had to spend dealing with other people. They had made this choice on principle believing that it was more important to facilitate the work of science than to profit from it.

In 1904 Pierre was finally offered a chair at the Sorbonne, the same year a second daughter, Eve, was born. And in 1905, he was offered membership in the French Academy of Science. The latter came with lab facilities and three posts, one of which he gave to Marie. Then tragedy struck in 1906, when Pierre fell in the street and was struck in the head and died.

Pierre’s death changed Marie. Joy and light seemed to be taken from her. Dr. Curie sustained his granddaughters and taught them about their father, because Marie refused to discuss him after his death. This would be especially important for Eve since she was less than two years old when he died. Marie would be actively involved in their lives, planning their education and being with them, but it was never the same.

Life is complicated and it is difficult if not impossible to determine cause and effect in many areas of our lives. But Pierre Curie understood his wife in a way that I’m not sure anyone else did. Her drive to study science was probably motivated by several things, interest and ability of course, but possibly a need to do the things that had been denied her father, as well as a need to retreat from every day life when depression threatened to overwhelm her.

It’s also impossible to give an accurate picture of a complicated person in 3000 words or less. Marie went on to become a professor at the Sorbonne in 1908 and win the 1911 Nobel Prize in Chemistry for her discovery of radium, an award that was almost derailed because of an affair with Paul Langevin. (This, in itself, is a study of how women were treated differently even in the “rational” world of science. The same standard certainly wasn’t applied to Langevin or to Einstein for that matter.) She oversaw the building of The Curie Institute, developed and implemented mobile X-ray machines during World War I, and even got involved in a little intrigue to prevent the Germans from getting their hands on radium during the war.

Marie continued to teach young scientists, although she would do no more original work of the caliber she did in her early life. Some (at least at the time) would try to claim this as evidence that Pierre was the real scientist of the two, but I don’t think this is the case. Many scientists do their best work at an early age. I think they were both exceptional scientists with individual accomplishments and an understanding of each other that brought out the best of each.

Note: The next woman to win a Nobel Prize would be Marie and Pierre’s daughter, Irene Joliot-Curie with her husband Frederic Joliot-Curie in 1935, the year after Marie’s death.

Madame Curie – Part I

One of the most famous pictures of Marie Curie is the photograph taken at the 1911 Solvay Conference. In it she is the only woman surrounded by some of the most well known scientists and mathematicians of her day: Perrin, Poincare, Einstein, Rutherford, and Langevin to name a few. It is easy to assume that genius is always recognized whether it is in a man or a woman, but Marie Curie’s fame was hard won. She also didn’t get there due exclusively to her own efforts, but in part due to the fact that there were those in her field who weren’t willing to let her be denied simply because she was a woman. There were scientists who worked against her, but also those who defended her, her discoveries, and her genius.

Marya Salomee Sklodowska, nicknamed Manya, was born in Warsaw on November 7, 1867. Her parents, Wladyslaw Sklodowski and Bronislava Boguski were intelligent members of the lower aristocracy. Their families no longer had wealth but they valued education and had a fierce loyalty to their native Poland. From the time of Manya’s birth until after World War I, the area of Poland where she was born and grew up was occupied by Russia. After several uprisings, the Russian government worked to suppress Polish nationalism.

Because of the suppression of the Polish people, although educated in St. Petersburg, Wladyslaw was a physicist who was not allowed to perform experiments or practice his science. He was reduced to taking low paying teaching positions in schools administered by Russians. Bronislava worked hard to get an education and worked her way up to becoming headmistress of the Freta Street School, a private school for girls in Warsaw. During this time, women were not expected to work outside their homes and were not eligible for higher education.

When Wladyslaw and Bronislava married in 1860, they moved into the apartment provided for Bronislava as the headmistress of the Freta Street School. Five children followed in six years: Zofia in 1862, Jozef in 1863, Bronislava (Bronya) in 1865, Helena in 1866, and Manya in 1867. The year Manya was born Wladyslaw received a position as assistant director of a Russian school on the western side of Warsaw which came with an apartment. The family moved and for a while Bronislava tried to continue in her position as headmistress. Eventually, the strain of caring for her family combined with travel to the Freta school and maintaining her job there took its toll and Bronislava resigned her position.

It seems that their family life was happy for a time. Both parents valued education and loved their children. At first Bronislava educated the older children at home, but her health began to decline. In 1871, when Manya was four, her mother began to show the classic symptoms of tuberculosis. Over the following years, she would go away several times for a “cure” taking Zofia with her as a nurse. When Manya was 10 her sister Zofia died from typhus. Two years later her mother succumbed to tuberculosis. These deaths hit Manya very hard. For most of her life she would suffer from periodic bouts of severe depression. At times she was able to hide it, retreating into a book, her studies, or later her work, but other times she would take to her bed refusing to eat or see anyone.

Manya continued her studies, graduating first in her class in 1883. This continued perseverance in the face of great loss took its toll. After she graduated she withdrew into despair. As a remedy, she was sent to spend the next year with relatives living in the country. She would later describe this year as one of the happiest of her life. Manya came back to Warsaw determined to work to help her family. She made a deal with her sister Bronya. She would work to help Bronya get her medical degree, then Bronya would in turn help her. To do this she took a series of jobs as a governess. One of these jobs was for the Żorawski family. During this time she fell in love with their son Kazimierz Żorawski. The feeling was mutual and they wanted to marry, but his parents were adamantly opposed to their son marrying a penniless governess.

In 1890, Bronya, who had finished her medical training and married another doctor, wrote to her sister to come to Paris. Manya still had hope that Kazimierz would be able to go against his parents and marry her. She decided not to go to Paris and began her scientific training in what was called the “Floating University.” The Floating University, or Flying University, was an underground, illegal, series of courses taught in private homes. The goal was to keep alive the Polish culture under the repressive rule of the Russians. This also provided a means for girls to get a higher education.

Eventually, Manya received a letter from Kazimierz which ended any thoughts of marriage in Manya’s mind and she decided to accept Bronya’s offer and go to Paris. In the fall of 1891, she arrived in Paris and taking the French form of her name, Marie, she entered the Sorbonne to study physics and mathematics. Initially staying with her sister, Marie found the constant activity in the home distracting and eventually rented a small garret room where she would spend her evenings studying, often without heat and neglecting her own health. She worked hard and received her degree in physics in 1893, and her degree in mathematics in 1894.

One of Marie’s professors, Gabriel Lippman, was able to get a small research opportunity for her to study magnetism. While attending the Floating University, Marie had begun work investigating magnetism in a laboratory run by a cousin, so it was an area of interest to her, but she had little laboratory space and poor equipment. Friends suggested that she consult a young scientist named Pierre Curie. Pierre had also done work in the area of magnetism which Marie was familiar with, but more importantly he and his brother Jacques had invented several pieces of equipment that would make Marie’s work much easier.

Pierre was a quiet man who had an unconventional upbringing. As a child he struggled learning some basic things such as reading and writing, but his genius in mathematics was recognized early. For this reason, his parents chose to educate him at home. Whether because of temperament or because of his early lack of experience with others outside the home, Pierre would always shy away from the public spotlight. This affected his ability to promote himself and achieve recognition in the form of lucrative positions in universities.

Before Marie met Pierre, he and Jacques had discovered piezoelectricity, a concept that explained the relationship between volume changes in crystal quartz and electricity. This discovery would become the foundation of many inventions in the future, such as sonar, ultrasound, and quartz wristwatches. It also brought Pierre and Jacques international acclaim in the scientific community. In spite of this, when Marie met Pierre, he was teaching at an industrial school for engineers with a small salary. It certainly wasn’t a position commensurate with his abilities or fame.

In many ways they were made for each other. Pierre never thought he would meet a woman who didn’t distract him from his science. Marie also had a need to be free from distraction, and in Pierre, she had met a man who not only understood her, but wasn’t threatened in any way by her genius. It took some persuading along with help from Marie’s sister Bronya and Pierre’s mother, but Marie finally agreed to marry Pierre in 1895. Although she needed persuading, they were very much in love, and after the wedding they settled down to work together.
