2011 International Year of ChemistryMarie Skłodowska CuriePolish-born French physicist and chemist. (7 November 1867 – 4 July 1934)
Marie Curie was a pioneer in the field of radioactivity and she discovered the elements polonium and radium. She was the first female professor at the University of Paris and the first woman to be awarded a Nobel Prize. In 1903 she, her husband Pierre Curie and Henri Becquerel jointly received the Nobel prize in Physics. A hundred years ago, in 1911, Marie was awarded the Nobel Prize in Chemistry. Curium (Cm), synthetic element 96, was named after Marie and Pierre Curie.
Dmitri Ivanovich MendeleevRussian chemist.(8 February 1834 – 2 February 1907) Mendeleev was one of the first to notice that elements showed regular repeating properties if they were listed according to their atomic mass. His ‘periodic table of elements’ is regarded as the backbone of modern chemistry. Mendelevium (Md), element 101, was named after him in 1955.
