Maria von Neumann

Maria Gertrude Goeppert Mayer (June 28, 1906 – February 20, 1972) was a German-American theoretical physicist who made groundbreaking contributions to nuclear physics and was the second woman to win the Nobel Prize in Physics. Born in Kattowitz, Upper Silesia (then part of Germany), Mayer emigrated to the United States with her husband Joseph Mayer, a chemist, and initially struggled to secure academic positions due to gender discrimination in academia. Despite these obstacles, Mayer conducted independent research and made significant contributions to theoretical physics. Her most famous contribution was the development of the nuclear shell model, which explained how protons and neutrons are arranged in atomic nuclei in shells analogous to electron shells in atoms. This model, developed in the 1950s, revolutionized nuclear physics and was immediately recognized as fundamental to understanding nuclear structure. Mayer shared the 1963 Nobel Prize in Physics with Hans Jensen and Eugene Wigner for this achievement. Her journey to recognition was long and often undervalued; she frequently worked without official appointment or adequate compensation despite her brilliance. Mayer's perseverance in pursuing physics despite systemic barriers made her an important role model for women in science. She was known for her rigorous thinking, creative problem-solving, and gracious personality. Mayer's legacy encompasses nuclear physics contributions, demonstrated excellence in theoretical physics, and the overcoming of gender-based barriers to scientific recognition and achievement.
