Gregory Pincus

Gregory Goodwin Pincus grew up in New Jersey, the child of Jewish farmers and teachers, and went into the biology of eggs and hormones when that still sounded slightly indecent in a university hallway. He was a serious experimentalist. He was also stubborn enough to keep going after Harvard decided he was too much trouble.

At the Worcester Foundation he and Min Chueh Chang studied how progesterone could quiet ovulation. Katherine McCormick paid the bills. John Rock ran the clinical work. Margaret Sanger had asked for a pill a woman could take. The collaboration was imperfect and historic.

Enovid was approved in 1960. The social arguments that followed belong to other pages. This page is about a Jewish scientist who treated reproduction as a system that could be understood and, carefully, altered. The method was endocrine, not rhetorical.

He died in 1967, before the pill’s long aftermath had a library. The accomplishment is the laboratory chain: a hormone, a trial, a tablet. Millions of ordinary mornings still run on that chain.
