Maria Goeppert Mayer was a German–American theoretical physicist who shared the 1963 Nobel Prize in Physics with J. Hans D. Jensen and Eugene Wigner. One half of the prize was awarded jointly to Goeppert Mayer and Jensen "for their discoveries concerning nuclear shell structure." She was the second woman to win the Nobel Prize in Physics, the first being Marie Curie in 1903. In 1986, the Maria Goeppert Mayer Award for early-career women physicists was established in her honor.
