Meet the scientists

Maria Goeppert Mayer (1906, Kattowitz, Poland – 1972, San Diego, USA)


As the only child of a sixth-generation academic, Maria Goeppert Mayer enrolled University of Göttingen in 1924 and she was awarded her doctorate in 1930.


For three decades, Goeppert Mayer followed her husband, the chemist Joseph Mayer, to Johns Hopkins University, then Columbia University, then the University of Chicago. At each university, she worked as a “fellow” or “research associate” or “volunteer associate professor,” but because of anti-nepotism rules, none of these universities gave her a salary or a full-time position.


In 1949, inspired by a question from Enrico Fermi, she proposed that inside the nucleus, protons and neutrons are arranged in a series of nucleon layers. After publishing her theory, Goeppert Mayer found that Hans Jensen and his colleagues had simultaneously made the same discovery. She and Jensen published a book together in 1955, and together they were awarded the 1963 Nobel Prize in Physics.


By that point she was, finally, a full professor. The University of California, San Diego, hired Goeppert Mayer in 1960, more than a decade after discovering the nuclear shell model, and 30 years after beginning her career as a scientist.
