Sir Robert Geoffrey Edwards CBE FRS MAE was an English physiologist and pioneer in reproductive medicine, and in-vitro fertilisation in particular.
Robert Edwards, in full Sir Robert Geoffrey Edwards a British medical researcher who developed the technique of in vitro fertilization (IVF). Edwards, together with British gynecologist Patrick Steptoe, refined IVF for the human egg. Their work made possible the birth of Louise Brown, the world’s first “test-tube baby,” on July 25, 1978. Edwards was awarded the 2010 Nobel Prize for Physiology or Medicine for his discoveries.

Edwards grew up in Manchester and served in the British army (1943–48). In 1949 he started to pursue a degree in agriculture at the University of Wales, but he soon switched his major to zoology. After receiving a B.Sc. (1951), he studied mouse embryos, artificial insemination, and infertility at the University of Edinburgh (Ph.D., 1955). Edwards continued his research at the California Institute of Technology (1957–58) in the United States, the National Institute for Medical Research, London (1958–62), and the University of Glasgow (1962–63) before joining the faculty at the University of Cambridge in 1963; he retired and became professor emeritus in 1989.

In 1968, the same year Edwards’s partnership with Steptoe began, he succeeded in fertilizing a human ovum outside the womb. Four years later they made their first attempt at implanting human embryos in women but were unsuccessful because of the hormone regimens they employed, which encouraged the release of multiple eggs (to improve the chances of fertilization) but also resulted in menstruation at the time of implantation. They ultimately abandoned that approach and instead chose to time the isolation, fertilization, and implantation of single eggs with the natural ovulation and menstrual cycle. In 1976 they met Lesley Brown, in whom their natural-cycle approach proved successful. Their work at the Centre for Human Reproduction in Oldham, England, resulted in the birth of more than 1,000 babies, including Louise Brown’s younger sister. In 1980 Edwards and Steptoe founded Bourn Hall Clinic in Cambridge
