25 July 1978: World’s first IVF baby is born

A new technique to help infertile couples attracts controversy when it results in what some call a ‘test tube baby’

If you had visited the Oldham and District General Hospital in the last week of July 1978, you might have been surprised to find security especially tight. But there was good reason for the heightened sense of tension. For it was here, shortly before midnight on 25 July, that Lesley Brown gave birth to her daughter Louise – then widely described as the world’s first ‘test tube baby’.

Today, when so many parents worldwide have benefited from the medical miracle of in vitro fertilisation (IVF), it seems remarkable that little Louise’s entrance into the world attracted such controversy. The process had been pioneered by the consultant gynaecologist Patrick Steptoe and the Cambridge research scientist Robert Edwards, who selected Mr and Mrs Brown from thousands of potential couples. Yet the next day’s headlines were full of predictions of disaster, with some columnists even talking of ‘Frankenbabies’, while some Catholic leaders were quick to object. “I have grave misgivings,” declared Cardinal Gordon Gray, the Archbishop of St Andrews and Edinburgh, “about the possible implica- tions and consequences for the future.”

For the Brown family, that moment on 25 July was of course one of unutter- able joy. But letters poured in from across the world, many of them downright abusive. One parcel from California contained a series of letters covered in red liquid, a broken glass test tube and a plastic foetus.

Still, there were messages of support, too. “I fear that you will find yourselves on the receiving end of all the usual criticism and condemnation that follows any medical breakthrough, so am writing to try in a tiny way to even things up,” read one letter, sent all the way from Australia. | Written by Dominic Sandbrook
