Those inspired by Sir Robert Edwards have paid tribute to a "remarkable man", "great mentor" and "pioneer" after he passed away at the age of 87.
Alongside Sir Richard Gardner, Professor Martin Johnson was Sir Robert’s first Graduate student between 1966 and 1969.
He is now Emeritus Professor of Reproductive Science at the University of Cambridge.
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.
The chief executive of Bourn Hall, the IVF clinic that Dr Patrick Steptoe and Edwards co-founded, added his own tribute.
Bob Edwards is one of our greatest scientists. His inspirational work in the early 60s led to a breakthrough that has enhanced the lives of millions of people worldwide. He is held in great affection by everyone who has worked with him and was treated by him. For me personally Bob was a great mentor, colleague and friend. It was a privilege to work with him and his passing is a great loss to us all.
