Gregory Pincus (died 1967) made his first breakthrough early, when he was able to produce rabbits through in-vitro fertilization. He also produced rabbits from unfertilized eggs (parthenogenesis). A rabbit produced this way appeared on the cover of Look Magazine in 1937.
In 1951, Margaret Sanger met Pincus at a dinner and procured a small grant for Pincus to begin hormonal contraceptive research. Pincus confirmed earlier research that progesterone would act as an inhibitor to ovulation. In 1952, Sanger told her friend Katharine McCormick about Pincus. In 1953 McCormick and Sanger met with Pincus to dramatically expand the scope of the research with a 50-fold increase in funding from McCormick.
In order to prove the safety of "the pill," human trials had to be conducted. These were initiated on patients of Dr. John Rock in Brookline, Massachusetts, using progesterone in 1953 and then three different progestins in 1954. Trials of the pill as a contraceptive could not be performed in Massachusetts, because dispensing contraception there was a felony. Puerto Rico was selected as a trial site in 1955, in part because there was an existing network of 67 birth control clinics servicing low-income women on the island. Trials began there in 1956. The trials were expanded to Haiti, Mexico, and Los Angeles.
Pincus's successes led to the first widely available oral contraceptive ("the pill"). His discoveries also led to the burgeoning sciences of steroidal hormone research, sex hormone research, and new forms of oncology. Pincus's work may be some of the most influential science of the twentieth century.
