On the night of 30 October 1986, a telephone switchboard in London took more than 50,000 attempted calls, most of them from children reporting sexual abuse. Dame Esther Rantzen, the broadcaster who built that switchboard into Childline, died on 30 September 2026 at the age of 86, less than three weeks after Parliament voted down the assisted dying law she had spent her final years urging it to pass.

Her family said in a statement that she had been "our sunshine." "We will always remember her endless capacity for joy, her ability to comfort every heartache, her beautiful way with words and her expert guidance in all things," they said, adding that she had been "the most wonderful mother" to her three children and a "cherished grandmother" to her five grandchildren.

The switchboard was meant to last one night. Rantzen had persuaded the BBC1 controller Michael Grade to let That's Life! broadcast a one-off special called Childwatch, inviting anyone who had suffered abuse as a child to call in. 'I will never forget walking into my office the morning after the programme to meet the social workers who had been running the helpline,' she said afterwards, describing the moment she decided the line could not simply close, according to Civil Society. Looking back on that night thirty years later, she remembered that "forty volunteers were valiantly trying to handle a staggering 50,000 calls," adding, "in an instant we could see just how essential the service was to the nation's children." With funding from the Variety Club and the Department of Health, and a freephone number and office space donated by BT, Childline launched later that year as a permanent, 24-hour service. Rantzen chaired it for nineteen years and remained its president for the rest of her life. By the time she died, the service that had begun as one emergency night was answering around a million contacts a year, by phone, text and online chat.

She had spent more than two decades building the platform that made that single broadcast possible. Born in Berkhamsted, Hertfordshire, in 1940, Rantzen read English at Somerville College, Oxford, joined the BBC in 1963 as a radio studio manager, and was reporting for the consumer programme Braden's Week by 1968. In 1973 she created and began presenting That's Life!, a BBC One magazine show mixing consumer complaints with comic filler and hard investigation; it ran for 21 years and drew audiences of more than 20 million at its peak, according to Somerville College, Oxford, which later made her an honorary fellow. Her production team also made Hearts of Gold, celebrating unrecognised acts of everyday courage, and The Big Time, which gave the teenage Sheena Easton her first television break. Looking back on the show much later, Rantzen said what she treasured most were "the fantastic friendships I have made thanks to That's Life!"

Rantzen married the broadcaster and documentary maker Desmond Wilcox in 1977; he died in 2000. Their three children, Miriam, Rebecca and Joshua, survive her along with five grandchildren. She also hosted the BBC Two talk show Esther from 1994 to 2002 and, in 2010, stood as an independent parliamentary candidate in Luton South, finishing fourth. She was appointed OBE for services to broadcasting in 1991, CBE for services to children in 2006, and Dame Commander of the Order of the British Empire in the 2015 New Year Honours for her work for children and older people through Childline and The Silver Line. She was also the first woman to receive BAFTA's Richard Dimbleby Award, and later received a lifetime achievement prize from Women in Film and Television.

The instinct that built Childline resurfaced in her seventies, turned toward a different kind of silence. After writing publicly at 71 about her own loneliness and hearing back from hundreds of older people living the same way, Rantzen founded The Silver Line in 2012. 'We needed a helpline just for older people,' she said of the idea, according to The Silver Line. It took its first call in November 2013 and was soon handling around 10,000 calls a week, before the service became part of the charity Age UK.

In her last years, Rantzen became one of the most recognisable public voices in Britain's campaign to change the law on assisted dying, giving evidence and pressing successive governments to grant parliamentary time for a vote. She had described the existing law as "messy and cruel" and argued that dying adults deserved the right to choose how their lives ended. 'I am not trying to impose my choice on anyone else, but I believe they should have no right to impose their choice on me,' she said on 11 September 2026, the day MPs considered the Terminally Ill Adults (End of Life) Bill, according to LBC. The Commons rejected the bill by 286 votes to 270, a defeat she called "a tragic day."

Rantzen never went back to the anonymity she had before that 1986 broadcast, and she did not try to. Childline still answers calls, texts and messages from children with nowhere else to turn, more than four million of them helped since that first switchboard rang. The Silver Line, folded into Age UK, still exists because she once said in public that she herself had felt lonely at seventy-one. Her daughter Rebecca continues to broadcast, carrying a surname now attached to two working helplines rather than to a single famous television programme.
