The German physicist and mathematician, Maria Goeppert-Mayer is prominent for her numerous contributions to the field of physics for which she earned the Nobel Prize in 1963. She was the first woman to win the Nobel Prize for theoretical physics, and second woman in history to win a Nobel Prize after Marie Curie. She is most famous for proposing the nuclear shell model of the atomic nucleus—a model of the atomic nucleus that provides a detailed description of the structure of the nucleus in terms of energy levels.
