Key Facts
- Born on July 19, 1921, in the Bronx, New York
- Developed the radioimmunoassay (RIA) with Solomon Berson in the 1950s
- First application of RIA to measure insulin in human blood (1959-1960)
- Received the Nobel Prize in Physiology or Medicine in 1977, the second woman to win it
- Died on May 30, 2011, in New York
Works & Achievements
She founded one of the first nuclear medicine departments, which would become a world-renowned research laboratory.
With Berson, she demonstrated that the body produces antibodies against injected insulin, an idea at first rejected by the major scientific journals.
Her major achievement: a technique capable of measuring hormones and other substances in minuscule quantities in the blood, which revolutionized medical diagnosis.
Foundational paper presenting the method for measuring insulin in human blood.
A choice not to file a patent so that the technique could spread freely around the world and benefit every patient.
The first woman to receive this prestigious distinction, often seen as an antechamber to the Nobel Prize.
An award honoring the development of the radioimmunoassay of peptide hormones; she was the second woman to receive this Nobel Prize.
The highest American scientific distinction, awarded for her body of work as a whole.
Anecdotes
As a teenager, Rosalyn devours the biography of Marie Curie written by her daughter Ève Curie. This book, which tells the story of a woman rejected and then triumphant in science, becomes her role model and convinces her that she too can become a physicist, even though it was a profession almost forbidden to women.
When she earns an assistantship scholarship at the University of Illinois in 1941, she is the only woman among the hundreds of teachers and researchers in the college of engineering, and the first since 1917. The war, which had sent so many young men to the front, opened a door usually closed to her.
At first, for lack of space, Rosalyn Yalow and Solomon Berson set up their radioisotope laboratory at the Bronx Veterans Administration hospital in a converted former janitor's closet. It is in this tiny room that a technique destined to change medicine worldwide would be born.
With Berson, she refuses to patent the radioimmunoassay (RIA). Rather than make money, they choose to freely share their invention so that laboratories all over the world can use it and save lives.
Solomon Berson, her research partner, dies in 1972. Since the Nobel Prize is never awarded posthumously, Rosalyn receives it alone in 1977. She never forgets her colleague: she names their laboratory after him and mentions him in all her speeches.
Primary Sources
The world cannot afford to lose the talents of half its people if we are to solve the many problems that beset us.
Radioimmunoassay makes it possible to measure substances present in the blood at minuscule concentrations, until then completely undetectable.
An immunological method makes it possible to measure the amount of insulin circulating in the plasma of human subjects.
Diabetic patients treated with insulin develop antibodies in their blood capable of binding to the injected hormone.
The immunoassay of insulin naturally produced by the body opens a new path for the study of hormones.
