Rose Epstein Frisch (born Rose Epstein; July 7, 1918 – January 30, 2015) was a pioneering American scientist in fertility and human development whose work was instrumental in the discovery of leptin.[5] [6] [7] She researched infertility and discovered that low body fat is a contributing factor to infertility.[8]
She was born Rose Epstein in 1918, in the Bronx, to Russian-Jewish immigrants Louis and Stella Epstein.[9] Her brother Lee Eastman (born Leopold Vail Epstein) is Linda McCartney's father.[10] Frisch attended Smith College in Northampton, Massachusetts, where she received a Bachelor of Arts in 1939. She earned her master's degree in zoology the following year at Columbia University, and her Ph.D. in genetics from the University of Wisconsin in 1943.[2] She met her husband, David H. Frisch, while she was at Smith and he was at Princeton. The two worked on the atomic bomb project at Los Alamos National Laboratory during the second World War.[11]
Focusing on the role of adipose tissue (fat) in fertility, Frisch discovered that low body fat (under 17%) could cause infertility, late menarche, and oligomenorrhea. This discovery was published in the journal Science in 1974.[12] In her work with Grace Wyshak she also discovered that athletes were at lower risk of breast cancer.[8]
Frisch began her research career as a doctoral student at the University of Wisconsin, where she worked with Drosophila melanogaster. After her doctorate, she became a human computer for the Manhattan Project.[8] Once her children were older, she took a research position at the Harvard Center for Population and Development Studies in Cambridge, Massachusetts. Frisch remained at Harvard for the rest of her career, studying swimmers, dancers, and other athletes to learn how body fat affects fertility and the propensity for diseases such as breast cancer.
Before her death, Frisch was involved with the Cambridge-based Center for Population and Development Studies of the Harvard T.H. Chan School of Public Health.[13]
Frisch was widely respected by athletic women, who were often able to achieve a pregnancy in part by applying knowledge gathered from her research.[8]
