Patrick Christopher Steptoe CBE FRS (9 June 1913, Oxford, England – 21 March 1988, Canterbury) was a British obstetrician and gynaecologist and a pioneer of fertility treatment.
Steptoe was responsible with biologist and physiologist Robert Edwards and the nurse Jean Purdy for developing in vitro fertilization.
Louise Joy Brown, the first test-tube baby, was born on 25 July 1978.
Edwards was awarded the 2010 Nobel Prize in Physiology or Medicine for his work on the development of in vitro fertilization; Steptoe was not eligible for consideration because the Nobel Prize is not awarded posthumously.
