Shown in their laboratory. By the time he met his future wife, Pierre Curie (1859 - 1906) had already established a name for himself as a scientist. In 1880, he and his brother had discovered piezoelectricity whereby physical pressure applied to a crystal resulted in the creation of an electric potential. He had also made important investigations into the phenomenon of magnetism including the identification of a temperature, the curie point, above which a material's magnetic properties disappear. However, shortly after his marriage to Marie Sklodowska (1867 - 1934) in 1895, Pierre subjugated his research interests to hers. Together, they began investigating the phenomenon of radioactivity recently discovered in uranium ore (although the phenomenon was discovered by Henri Becquerel, the term radioactivity was coined by Marie). After chemical extraction of uranium from the ore, Marie noted the residual material to be more 'active' than the uranium itself. She concluded that the ore contained, in addition to uranium, new elements that were also radioactive. This led to the discoveries of the elements polonium and radium. Four more years of processing tons of ore under oppressive conditions were required to isolate enough of each element to determine its chemical properties. For their work on radioactivity, the Curies were awarded the 1903 Nobel Prize in physics. Tragically, Pierre was killed three years later in an accident while crossing a street in a rainstorm. Pierre's teaching position at the Sorbonne was given to Marie. Never before had a woman taught there in its 650 year history! Her first lecture began with the very sentence her husband had used to finish his last. In his honor, the 1910 Radiology Congress chose the curie as the basic unit of radioactivity: the quantity of radon in equilibrium with one gram of radium. A year later, Marie was awarded the Nobel Prize in Chemistry for her discoveries of radium and polonium, thus becoming the first person to receive two Nobel Prizes. For the remainder of her life she tirelessly investigated and promoted the use of radium as a treatment for cancer. Marie Curie died July 4, 1934, overtaken by pernicious anemia no doubt caused by years of overwork and radiation exposure.
