The life of a forgotten physicist"},"content":{"rendered":"

In 1977, an American physicist named John H. Van Vleck won the Nobel prize for his work on magnetism. In his Nobel lecture<\/a>, amid a discussion of rare earth elements, one sentence leaps out:<\/p>\n

Miss Frank and I made the relevant calculations.<\/p>\n

Who was Miss Frank? Van Vleck credits her with key work on the quantum mechanics of magnetism, but she is almost absent from the history books.<\/p>\n

Amelia Frank published a handful of scholarly papers which are well-cited for the time. Yet histories of physics mostly mention her only as the wife of Eugene Wigner, who was himself awarded the physics Nobel in 1963.<\/p>\n

Why don\u2019t we know more about Frank, and why aren\u2019t her contributions recognised? When we searched through the archives, we found a remarkable scientific life unfolding at the dawn of quantum mechanics.<\/p>\n

A bright beginning<\/p>\n

Born in 1906, Amelia Z. Frank grew up a junkyard owner\u2019s daughter in Adrian, Michigan. Local newspaper reports<\/a> paint her as a bright, accomplished teen and an independent thinker.<\/p>\n

As an undergraduate at a leading women\u2019s university, Goucher College, Frank joined the physics club. Her senior yearbook relates that her presentation on the Compton effect<\/a> \u2013 a description of how light interacts with electrically charged particles, named after Arthur Compton \u2013 was both highly technical and engaging. <\/p>\n

Nine months later, Compton<\/a> gained wide public recognition with the award of the 1927 Nobel prize<\/a> for demonstrating that X-rays could behave like particles. Frank clearly had her finger on the pulse of the quantum mechanical revolution then occurring in physics.<\/p>\n

Where many scholars intrigued by the quantum frontier pursued their study in Europe, Frank went to the University of Wisconsin. There, she met the recently recruited Van Vleck.<\/p>\n

Quantum innovation<\/p>\n

Arriving in Madison in 1928, Frank had placed herself at the American centre of quantum innovation.<\/p>\n

At that time, quantum mechanics could describe isolated particles or atoms, but puzzling out the behaviour of solid materials was proving difficult.<\/p>\n

\"Front<\/a><\/p>\n

Part of Amelia Frank\u2019s PhD thesis was published in 1932.
\n Physical Review<\/a><\/p>\n

Magnetism was the perfect testbed, as it can only be explained by quantum mechanics \u2013 not classical physics. Frank, supervised by Van Vleck, turned to rare earth elements, where magnetism is strong and existing theories were insufficient. Could quantum physics resolve this conundrum?<\/p>\n

Frank\u2019s thesis, partially published in Physical Review in 1932<\/a>, focused on the element samarium. It showed quantum mechanical corrections were needed to explain the experimental data and contains a plot that appears in Van Vleck\u2019s Nobel lecture, labelled \u201cV.V. & F\u201d.<\/p>\n

Hard times<\/p>\n

After her PhD, Frank worked as a tutor at the University of Wisconsin and continued her research. Her 1935 article on crystal field theory<\/a> showed how samarium\u2019s energy levels shift due to neighbouring atoms. <\/p>\n

Colleagues described her as a promising scholar and her publication record was good. But she faced barriers that slowed her work.<\/p>\n

Money was one issue. Frank was supporting her younger sister, an undergraduate chemistry student, and it was the middle of the Great Depression. <\/p>\n

In an unpublished 1935 letter we found in Box 12, Folder 214 of the J. H. Van Vleck papers<\/a> held by the American Institute of Physics in the Niels Bohr Library and Archive<\/a>, Frank told Van Vleck she\u2019d had to take another job to survive: <\/p>\n

Our finances were in such bad shape that I suggested to various people that I\u2019d be interested in typing [\u2026] and so I have taught classes, tutored, typed and cooked, but I have not finished my paper.<\/p>\n

Van Vleck was seeking positions for Frank, but jobs were scarce \u2013 and as a Jewish woman in that era, Frank would have faced multiple forms of discrimination.<\/p>\n

Marriage and death<\/p>\n

Ultimately, Frank left physics, resigning from the University of Wisconsin around October 1936. When Van Vleck asked why, Frank let him in on a then-closely guarded secret: she had started a relationship with new colleague Eugene Wigner<\/a>. <\/p>\n

The pair married shortly before Christmas. Wigner described himself as astonished by his love for her. <\/p>\n

But their happiness didn\u2019t last. Just weeks after the wedding, Frank fell ill. <\/p>\n

Wigner said it was her heart, others said it was cancer. Either way, Frank\u2019s condition was grave. <\/p>\n

After months in hospital, she returned to Michigan. She passed away in her parents\u2019 home on August 16 1937. She was 31.<\/p>\n

An enduring contribution<\/p>\n

Frank\u2019s untimely death is one reason why she is under-recognised today. But it is not a sufficient one.<\/p>\n

Frank kept company with other trailblazing women across the country. Her flatmate in Wisconsin was Mary Bunting<\/a>, who was later president of the women-only Radcliffe College and oversaw its integration with Harvard.<\/p>\n

Frank\u2019s ambition, intellect and drive took her to the frontiers of knowledge. There, Van Vleck\u2019s support kept her in physics long enough to make lasting, if overlooked, contributions. <\/p>\n

Ninety years have passed, but Frank\u2019s life exemplifies women\u2019s ongoing experiences in physics, good and bad. <\/p>\n

Women remain drastically under-represented in quantum physics. To take one example, a 2023 survey found 87.5% of full-time Australian quantum researchers were men<\/a>.<\/p>\n

Women remain more likely than men to have caring responsibilities that increase financial stress and reduce research time. And mentorship and purposeful community-building remain vital to bring women into the field \u2013 and keep them there.<\/p>\n

In the end, this may be Frank\u2019s most enduring contribution to quantum physics. Recovering her story is important because it allows her scientific contributions to be appropriately recognised. Perhaps more importantly, her story reminds us that women have belonged in quantum physics from the beginning.<\/p>\n","protected":false},"excerpt":{"rendered":"In 1977, an American physicist named John H.
