Fifty-two years after Marie Curie, society believed women were unsuited for academic or scientific work. Maria Goeppert Mayer pursued her interests, anyway. And she became the second woman to win the Nobel Prize in physics.
Friedrich Goppert, and his wife Maria, lived in Kattowitz (now Katowice, Poland). Their only child, Maria Goeppert Mayer, was born on June 28, 1906.
They moved from Kattowitz when her father, a sixth-generation university professor, accepted an appointment as the professor of pediatrics at the University of Göttingen in 1910.
She claimed she was closer to her father because being a scientist; he was a more interesting.
Only one school in 1921 Göttingen would prepare girls to take the university entrance exam, the abitur. It closed its doors a year before she would have graduated.
She took the university entrance exam, anyway. And passed the exam at 17 years old, a year earlier than most. Fewer than one in ten German university students were female.
Maria entered the mathematics program at the University of Göttingen. But changed to physics. It interested her more.
Her doctoral thesis explained her theory of two-photon absorption (aka excitation). Though there was no way to prove her theory then, she earned her doctorate in 1930.
Marriage & Career
American Joseph Edward Mayer boarded with her family. They married on January 19, 1930. The couple moved to the United States. Johns Hopkins University had hired him as an associate professor of chemistry.
The university would not hire Maria as a professor because of strict anti-nepotism rules. Similar rules existed at most universities during the depression. They kept her from getting a job consistent with her education level.
The university hired her as an assistant in the Physics Department. She taught some courses and worked with German correspondence. She received a tiny salary, a place to work, and access to the facilities. That was important to her. She worked with Karl Herzfeld. Herzfeld was an Austrian-American physicist. They collaborated on several papers.
During the summers, she returned to Göttingen to work and collaborate with her former examiner, Born.
She and Joe had two children, Mary Ann and Peter.
World War II
The rise of the Nazis ended her trips to Germany. Soon after the war started, her husband, Joe, was fired. They suspected the dean of physical sciences fired him to get Maria out of the laboratory, but it could have been that there were too many German scientists in the department or because of complaints that his chemistry lectures contained too much modern physics.
He accepted a position at Columbia University in 1940. They gave Maria an office but not a paid or official position. She kept working because physics was fun.
Within nine years, she produced ten papers applying quantum mechanics to chemistry, one of which became a milestone. Also, with her husband, she wrote Statistical Mechanics, a textbook that sold for 44 years.National Women’s Hall of Fame
A Paid Professional
She got her first paid professional position in December 1941, teaching science part-time at Sarah Lawrence College.
In early 1942, she joined the Manhattan Project. She was part of a project to discover a way to separate the fissile uranium-235 isotope in natural uranium. It was impractical then.
We found nothing, and we were lucky… we escaped the searing guilt felt to this day by those responsible for the bomb.Maria Goeppert Mayer via www.nobelprize.org
A Nobel Prize Worthy Idea
After the war, she worked another unpaid job at the University of Chicago. Around that time, she received a part-time job offer to work in nuclear physics at Argonne National Laboratory. She protested she knew nothing about nuclear physics, but took the job.
Two years later (1949), she proposed that inside the nucleus, there was a series of layers of protons and neutrons, arranged like the layers of an onion, with neutrons and protons spinning around their axes and orbiting the center of the nucleus at each level.
After she published her theory, she learned that Hans Jensen and his colleagues had simultaneously made the same discovery. She and Jensen published a book together.
A Full Professorship
In 1959, more than thirty years after beginning her career as a scientist, The University of California, San Diego hired Maria as a full professor.
The Nobel Prize
They awarded Maria Goeppert Mayer and J. Hans D. Jensen half the Nobel Prize in Physics in 1963 for their proposal of the shell nuclear model. (Eugene P. Wigner of the United States won the other half for unrelated work.)
She was the second woman who won the Nobel Prize in physics, after Marie Curie. (It was another fifty years before another woman won the prize).
Death and Legacy
Maria suffered a stroke shortly after moving to California, but returned to work for years. In 1971, she had a heart attack and slipped into a coma. She never regained consciousness and died of heart failure on February 20, 1972.
In her honor, the American Physical Society (APS) created the Maria Goeppert Mayer Award for young female physicists at the beginning of their careers. Argonne National Laboratory also presents an annual award in her honor to young women scientists or engineers. On Venus, there is a crater about 35 km in diameter that is named Crater Goeppert Mayer. They inducted Maria into the Women’s Hall of Fame and included her in the third American Scientists collection of US postage stamps.
Her impact on science, on physics, was enormous. She changed our understanding of atoms.
Second Woman Who Won the Nobel Prize
Maria Goeppert Mayer didn’t plan to win the Nobel Prize. Didn’t think about it when she made her discovery. She was just excited to find the last piece of the puzzle she wanted to solve.
Being second isn’t losing when you’re the second woman who won the Nobel Prize in physics. But is her name as common as Marie Curie? I didn’t study physics, and I never heard of her before. Did you know Maria discovered the “layers” of protons and neutrons around an atom’s nucleus?
