A colorfully illustrated, pocket-size picture book biography of influential physicist and chemist Marie Curie. Marie Curie, the first woman ever to win a Nobel Prize and only person to win it in two different scientific fields, was a physicist and chemist. As she conducted pioneering research, Marie Curie coined the term "radioactivity," developed some of the first techniques for isolating radioactive isotopes. She also discovered two elements: polonium and radium, and developed mobile X-ray units for use in field hospitals during World War I. In 1934, at the age of sixty-six, she died of complications from long-term exposure to radiation. Pocket Bios are full of personality, introducing readers to fascinating figures from history with simple storytelling and cheerful illustrations.
