After Brown was born, Braude recalled a celebration at Cambridge, where scientists toasted Edwards and Steptoe's achievement by drinking champagne out of plastic cups.
Braude said public opinion has evolved considerably since then.
"I think people now understand that (Edwards) only had the best motivation," he said. "There are few biologists that have done something so practical and made a huge difference for the entire world."
In 2010, Edwards was awarded the Nobel prize in medicine or physiology for the development of IVF. Steptoe had already passed away; the Nobel prizes are not awarded posthumously. The Roman Catholic Church denounced the award, arguing that human life should only begin through intercourse and not artificially. The Vatican said Edwards "bore a moral responsibility for all subsequent developments in assisted reproduction technology and for all abuses made possible by IVF."
In 2011, Edwards was knighted by Queen Elizabeth II "for services to human reproductive biology."
Other scientists called Edwards a visionary who forever changed the lives of people helped by IVF and the medical community.
"(Edwards') inspirational work in the early 60s led to a breakthrough that has enhanced the lives of millions of people worldwide," Mike Macnamee, chief executive of the IVF clinic that Edwards and Steptoe co-founded, said in a statement. "It was a privilege to work with him and his passing is a great loss to us all."
