Marie and Pierre Curie in their laboratory in Paris. Pierre Curie was introduced to Maria Sklodowska by a friend and took Maria into his laboratory as his student. He began to regard her as his muse. She refused his initial proposal, but finally agreed to marry him on July 26, 1895. Marie Curie (November 7, 1867 - July 4, 1934) was a Polish-French physicist and chemist. She was the first woman to win a Nobel Prize, the only woman to date to win in two fields, and the only person to win in multiple sciences. Her achievements included a theory of radioactivity (a term that she coined), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Pierre Curie (May 15, 1859 -April 19, 1906) was a French physicist, a pioneer in crystallography, magnetism, piezoelectricity and radioactivity, and Nobel laureate. Pierre studied ferromagnetism, paramagnetism, and diamagnetism for his doctoral thesis, and discovered the effect of temperature on paramagnetism which is now known as Curie's law. The material constant in Curie's law is known as the Curie constant. No photographer credited, circa 1900s.
