Maria Sklodowska-Curie

(1867—1934) 

Maria (Marie Fr.) Sklodowska-Curie (born in Warsaw, Poland, on November 7, 1867) was one of the first woman scientists to win worldwide fame, and indeed, one of the great scientists of this century. She had degrees in mathematics and physics. Winner of two Nobel Prizes, for Physics in 1903 and for Chemistry in 1911, she performed pioneering studies with radium and polonium and contributed profoundly to the understanding of radioactivity.

Perhaps the most famous of all women scientists, Maria Sklodowska-Curie is notable for her many firsts:

She was the first to use the term radioactivity for this phenomenon.

She was the first woman in Europe to receive her doctorate of science.

In 1903, she became the first woman to win a Nobel Prize for Physics. The award, jointly awarded to Curie, her husband Pierre, and Henri Becquerel, was for the discovery of radioactivity.

She was also the first female lecturer, professor and head of Laboratory at the Sorbonne University in Paris (1906).

In 1911, she won an unprecedented second Nobel Prize (this time in chemistry) for her discovery and isolation of pure radium and radium components. She was the first person ever to receive two Nobel Prizes.

She was the first mother-Nobel Prize Laureate of daughter-Nobel Prize Laureate. Her oldest daughter Irene Joliot-Curie also won a Nobel Prize for Chemistry (1935).

She is the first woman which has been laid to rest under the famous dome of the Pantheon in Paris for her own merits.

She received 15 gold medals, 19 degrees, and other honors. A truly remarkable figure in the history of science !

Maria Sklodowska-Curie became the first Pole to receive a Nobel Prize.

Maria Sklodowska was born as the fifth and youngest child of Bronsilawa Boguska, a pianist, singer, and teacher, and Wladyslaw Sklodowski, a professor of mathematics and physics. When she was little and living in Poland, her nickname was Manya. From childhood she was remarkable for her prodigious memory, and at the age of 16 she won a gold medal on completion of her secondary education at the Russian lycee. Because her father, a teacher of mathematics and physics, lost his savings through bad investment, she had to take work as a teacher and, at the same time, took part  clandestinely in the nationalist "free university," reading in Polish to women workers. At the age of 18 she took a post as governess, where she suffered an unhappy love affair. From her earnings she was able to finance her sister Bronia's medical studies in Paris, on the understanding that Bronia would in turn later help her to get an education.

In 1891 Maria Sklodowska went to Paris and began to follow the lectures of  Paul Appel, Gabriel Lippmann, and Edmond Bouty at the Sorbonne. There she met physicists who were already well known—Jean Perrin, Charles Maurain, and Aim Cotton. Sklodowska worked far into the night in her students' quarter garret and virtually lived on bread and butter and tea.

She came first in the licence of physical sciences in 1893. She began to work in Lippmann's research laboratory and in 1894 was placed second in the licence of mathematical sciences. It was in the spring of this year that she met Pierre Curie.

Maria Sklodowska is daughter of a Polish freethinker but reared by a Catholic mother. She abandoned the Church before she was 20 and her marriage with Pierre Curie was a purely civil ceremony because she says in her memoir of him, Pierre belonged to no religion and I did not practice any.

Their marriage (July 25, 1895) marked the start of a partnership that was  soon to achieve results of world significance, in particular the discovery of polonium (so called by Maria in honour of Poland) in the summer of 1898, and that of radium a few months later. Following Henri Becquerel's discovery (1896) of a new phenomenon (which she later called "radioactivity"), Maria Curie, looking for a subject for a thesis, decided to find out if the property discovered in uranium was to be found in other matter. She discovered that this was true for thorium at the same time as G.C. Schmidt did.

Turning to minerals, her attention was drawn to pitchblende, a mineral whose  activity, superior to that of pure uranium, could only be explained by the presence in the ore of small quantities of an unknown substance of very high activity. Pierre Curie then joined her in the work that she had undertaken to resolve this problem and that led to the discovery of the new elements, polonium and radium. While Pierre Curie devoted himself chiefly to the physical study of the new radiations, Maria Curie struggled to obtain pure radium in the metallic state— achieved with the help of the chemist A.  Debierne, one of Pierre Curie's pupils. On the results of this research Maria Curie received her doctorate of science in June 1903 and, with Pierre,  was awarded the Davy Medal of the Royal Society. Also in 1903 they shared with Becquerel the Nobel Prize for Physics for the discovery of radioactivity.

The birth of her two daughters, Irene and Eve, in 1897 and 1904, did not  interrupt Maria's intensive scientific work. She was appointed lecturer in physics. In December 1904 she was appointed chief assistant in the laboratory  directed by Pierre Curie.

The sudden death of Pierre Curie (April 19, 1906) was a bitter blow to Maria  Curie, but it was also a decisive turning point in her career: henceforth  she was to devote all her energy to completing alone the scientific work that they had undertaken. On May 13, 1906, she was appointed to the professorship that had been left vacant on her husband's death; she was the first woman to teach in the Sorbonne. In 1908 she became titular professor, and in 1910 her fundamental treatise on radioactivity was published. In 1911 she was awarded the Nobel Prize for Chemistry, for the isolation of pure radium. In 1914 she saw the completion of the building of the laboratories of the Radium Institute (Institut du Radium) at the University of Paris.

Throughout World War I, Maria Curie, with the help of her daughter Irene, devoted herself to the development of the use of X-radiography. In 1918 the Radium Institute, the staff of which Irene had joined, began to operate in earnest, and it was to become a universal centre for nuclear physics and  chemistry. Maria Curie, now at the highest point of her fame, and, from 1922, a member of the Academy of Medicine, devoted her researches to the study of the chemistry of radioactive substances and the medical  applications of these substances.

In 1921, accompanied by her two daughters, Maria Curie made a triumphant  journey to the United States, where President Warren G. Harding presented her with a gram of radium bought as the result of a collection among American women. She gave lectures, especially in Belgium, Brazil, Spain, and Czechoslovakia. She was made a member of the International Commission on Intellectual Co-operation by the Council of the League of Nations. In addition, she had the satisfaction of seeing the Curie Foundation in Paris develop and the inauguration in 1932 in Warsaw of the Radium Institute, of which her sister Bronia became director.

On July 4, 1934, near Sallanches (France), Maria Sklodowska-Curie died of  leukaemia, which has a number of standard consequences, one of which can be aplastic anaemia caused by her exposure to the radium that made her famous.

Recognizing Maria Sklodowska-Curie with perhaps its highest posthumous honor  in 1995, the French Government transferred her ashes, together with those of  Pierre, to the Pantheon in Paris, making her the only woman (she is the first woman, again) to be recognized in this way for her own achievements.
