Marie Curie is the first woman in the world to receive a Nobel Prize. Together with her husband, Pierre Curie, she discovered radioactivity, which was the beginning of her brilliant scientific career, which culminated in the appearance of two new elements in the periodic table of Mendeleev - radium and polonium. Maria was a tireless worker, and Pierre's premature death could not extinguish her passion for science. Despite the fact that the research seriously harmed the woman’s health, she did not interrupt her work in the laboratory, and when the First World War broke out, she was able to put her achievements to the service of the sick and wounded. Marie Curie's death was the result of her love of science, but her discoveries saved thousands of lives.
