I will speak about Robert Edwards. Born in 27 September 1925 and died on 10 April 2013, Robert was an English physiologist and pioneer in reproductive medicine, and in-vitro fertilisation (IVF) in particular. Who in 2010, was awarded the Nobel Prize for the development of human in vitro fertilization (IVF) therapy.
As early as the 1950s, Edwards had the vision that IVF could be useful as a treatment for infertility. He worked systematically to realize his goal, discovered important principles for human fertilization, and succeeded in accomplishing fertilization of human egg cells in test tubes (or more precisely, cell culture dishes). His efforts were finally crowned by success on 25 July, 1978, when the world's first "test tube baby" was born.
