Pioneering Chemist: A Legacy of Research in Proteins and Cancer
The history of biochemistry is marked by individuals who broke barriers both in the laboratory and in academia. One such pioneer dedicated her career to understanding the complex physical and chemical properties of proteins, contributing vital data to the fields of immunology and oncology while paving the way for women in scientific leadership.
Early Career and Breakthroughs in Protein Chemistry
Following the completion of her doctorate, she began her professional journey at the University of Wisconsin. In a landmark appointment, she became the first female chemist staff member in the physical chemistry department, serving as a postdoctoral researcher until 1945.
During her tenure at Wisconsin, she collaborated with John Warren Williams and Alwin M. Pappenheimer to investigate the physical chemistry of proteins. Their work focused heavily on antibody-antigen interactions—the specific binding between antibodies and the foreign substances (antigens) they target. Specifically, they analyzed the interaction between diphtheria toxin and its corresponding antitoxin.
By utilizing ultracentrifugation (a technique that uses high-speed rotation to separate particles based on size and density), the team discovered that approximately two-thirds of the native diphtheria antitoxin was "inactive." This portion, later identified as the Fc portion of IgG, could be removed via protease treatment without hindering the antitoxin's ability to bind two antigen molecules. This finding suggested that the binding sites were located close together. This critical research provided a foundation for Rodney Porter's subsequent determination of immunoglobulin structure, a feat for which Porter was awarded the 1972 Nobel Prize.

Contributions to the War Effort
During World War II, her expertise was utilized by the National Defense Research Council's Committee on Medical Research. She conducted studies on human serum albumin, developing essential methods to purify the protein for use as a blood substitute.
Advancing Cancer Research at Sloan-Kettering
In 1945, she transitioned to New York City, taking a position as a chemist at Memorial Hospital to study how plasma proteins influence metastasis (the spread of cancer cells from the primary site to other parts of the body). By 1946, she joined the newly established Sloan-Kettering Institute for cancer research to investigate the role of nucleoproteins in cancer.
Her ascent within the institute was marked by several milestones. Initially a Finney-Howell Foundation fellow, she was promoted to associate member in 1960. In 1963, she became the first female full member of the Sloan-Kettering Institute.

Academic Leadership at Cornell University
Parallel to her research, she shared her knowledge as a teacher of biochemistry at Cornell University's Sloan-Kettering Division of the Graduate School of Medical Sciences. Her academic achievements culminated in her becoming the first female full professor at Cornell.
Recognition and Professional Legacy
Her contributions to science were recognized with prestigious awards. In 1963, she received the Sloan Award for cancer research, which funded a trip to Europe to lecture and collaborate in the laboratory of Nobel laureate Arne Tiselius. In 1966, the American Chemical Society honored her with the Garvan Medal, a national award dedicated to women who have made exemplary contributions to chemistry.
Throughout her career, she authored approximately 100 scientific papers and published a definitive book in 1964 titled The Physical and Chemical Properties of Ribosomes.

After retiring from Cornell in 1973, she continued her commitment to supporting women in science by founding and serving as the first president of the Memorial Sloan Kettering Cancer Association for Professional Women.
