This discovery led to the study of radioactivity and the development of nuclear physics.<\/p>\n<p>Marie Curie was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two different scientific fields. She was born Maria Salomea Sk\u00c5\u0082odowska in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw&#8217;s clandestine Floating University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronis\u00c5\u0082awa to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and physicist Henri Becquerel. She won the 1911 Nobel Prize in Chemistry.<\/p>\n<p>Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS was a New Zealand physicist who played a leading role in the development of nuclear physics.
