Professor Sir Robert Edwards was knighted in 2011
The IVF pioneer and Nobel prize winner Professor Sir Robert Edwards has died aged 87.
His work led to the birth of Louise Brown, the first "test-tube baby" in July 1978.
The University of Cambridge, where Prof Edwards was a fellow of Churchill College, said his work "had an immense impact throughout the world".
He was knighted in 2011, a year after being awarded the Nobel prize for medicine, reports the BBC.
Professor Martin Johnson was, together with Sir Richard Gardner, Prof Edwards's first graduate student at the University of Cambridge.
He said: "Bob Edwards was a remarkable man who changed the lives of so many people.
"He was not only a visionary in his science but also in his communication to the wider public about matters scientific in which he was a great pioneer.
"He will be greatly missed by his colleagues, students, his family and all the many people he has helped to have children."
