Gregory Goodwin Pincus

Summary
Gregory Goodwin Pincus (April 9, 1903 – August 22, 1967) was an American biologist and researcher who co-invented the combined oral contraceptive pill. Gregory Goodwin Pincus was born in Woodbine, New Jersey to Jewish parents, who were immigrants from the Russian Empire. His father was Joseph Pincus, a teacher and the editor of a farm journal, and his mother was Elizabeth (née Lipman), whose family had come from the region that is now Latvia. He credited two uncles, both agricultural scientists, for his interest in research. His IQ was said to be 210 and his family considered him a genius. Pincus attended Cornell University and received a bachelor's degree in biology in 1924. He attended Harvard University, where he was an instructor in zoology while also working toward his master's and doctorate degrees. From 1927 to 1930 he moved from Harvard to Cambridge University in England to the Kaiser Wilhelm Institute for Biology with Richard Goldschmidt in Berlin where he performed research. He became an instructor in general physiology at Harvard University in 1930 and was promoted in 1931 to an assistant professor. Dr. Pincus began studying hormonal biology and steroidal hormones early in his career. He was interested in the way that hormones affected mammals' reproductive systems. His first breakthrough came early, when he was able to produce in vitro fertilization in rabbits in 1934. In 1936, he published his discoveries after his experiments. His experiments involving parthenogenesis produced a rabbit that appeared on the cover of Look magazine in 1937. To create the in vitro rabbit baby, Pincus removed the ovum from the mother rabbit and placed it in a solution mixture of saline and estrone. Afterwards, he placed the "fertilized" ovum back into the rabbit. Pincus' experiment became known as "Pincogenesis" because other scientists were unable to attain the same results when conducting the experiment. After he was misquoted in an interview, it was believed that his experiment was the beginning of the use of in vitro for humans.
