Patrick Christopher Steptoe CBE FRS was an English 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 fertilisation. 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 fertilisation; Steptoe was not eligible for consideration because the Nobel Prize is not awarded posthumously.
