Rosalyn Yalow, Dead at 89

One of the first female Nobel Laureates, revered alumna of the University of Illinois at Urbana, discoverer of the radioimmunoassay among other things. From the NYT:

World War II and the draft were creating academic opportunities for women; to her delight, Dr. Yalow was awarded a teaching assistantship at the College of Engineering at the University of Illinois. She tore up her steno books and headed to Champaign-Urbana, becoming the first woman to join the engineering school’s faculty in 24 years.

Dr. Yalow received her doctorate in nuclear physics in 1945, and went to teach at Hunter College the following year. When she could not find a research position, she volunteered to work in a medical lab at Columbia University, where she was introduced to the new field of radiotherapy. She moved to the Bronx Veterans Administration Hospital, now the James J. Peters Veterans Affairs Medical Center, as a part-time researcher in 1947 and began working full time in 1950. That same year, she began her 22-year collaboration with Dr. Berson.

In their work on radioimmunoassay, Dr. Yalow and Dr. Berson used radioactive tracers to measure hormones that were otherwise difficult or impossible to detect because they occur in extremely low concentrations. They went on to use the test to measure concentrations of vitamins, viruses and other substances in the body.

I remember passing her portrait at the Illini Union on the many nights I spent there studying. An inspiration.
