Sir Robert Geoffrey Edwards   

British physiologist and pioneer in Reproductive medicine and in-vitro fertilization (IVF) in particular.   Edwards successfully pioneered conception through IVF, which led to the birth of the first test-tube baby , on 25 July 1978.   

He was awarded the 2010 Nobel Prize in Physiology or Medicine "for the development of in vitro fertilization". Edwards was born in Manchester, he served in the British Army, studies in agriculture and he studied at the Institute of Animal Genetics.In about 1960 Edwards started to study human fertilization. In 1968 he was able to achieve fertilization of a human egg in the laboratory. Edwards developed human culture media to allow the fertilization and early embryo culture, while Steptoe utilized laparoscopy to recover ovocytes from patients with tubal infertility. Their attempts met significant hostility and opposition.In vitro fertilization meant a new way to help infertile couples who formerly had no possibility of having a baby. Refinements in technology have increased pregnancy rates and it is estimated that in 2010 about 4 million children have been born by IVF   Edwards and Steptoe founded the Bourn Hall Clinic as a place to advance their work and train new specialists. His wife is Ruth Fowler Edwards, the granddaughter of physicist Ernest Rutherford and daughter of physicist Ralph Fowler.  

I choose Robert Geoffrey Edwards, because from my point of view, he change lives of a lot of couples, givin the option to have a child if one of the couple is esteril and thanks his work a lot of child born, because of that reasons I see good that gave them the nobel prize.
