Sir David Attenborough at 100

Today Sir David Attenborough turned 100. We reflect on his role as the ultimate “stand besider”.

He was born on 8 May 1926, joined the BBC in 1952, and over more than seven decades helped shape not only natural history broadcasting, but the way millions of people understand the living world. His career spanned Zoo Quest in the 1950s to the great Life series, from Life on Earth to Planet Earth, Blue Planet, and beyond. He also helped shape television itself, serving as Controller of BBC Two in the 1960s before returning fully to programme-making.

For many people, Sir David was not simply a broadcaster. One of ISB’s founders, Nathalie Seddon, often notes that many of her friends and colleagues, now in leading roles across conservation and environmental science, were first drawn to biology by David Attenborough’s films. Students still say the same today. Again and again, they cite his programmes as the moment something opened: a sense of wonder, a scientific curiosity and often a desire to devote a life to the living world.

That is an extraordinary legacy. It is one thing to inform. It is another to help shape the moral and imaginative lives of generations. Attenborough has done both. Life on Earth, first broadcast in 1979, became a landmark in the history of wildlife television and established a form of storytelling that changed the genre. Over time, his work helped make ecological literacy part of public culture. He brought distant forests, reefs, deserts, polar seas and deep oceans into ordinary homes, and in doing so expanded the circle of lives people could recognise, care about and remember.

He has also changed with the times. In his later decades, his work became more direct about ecological breakdown, climate change and the urgency of repair. At COP24 in 2018 he warned of a “man-made disaster of global scale”, and his recent film Ocean argued that recovery is still possible if protection is implemented at speed and scale. Even at 99, he was still fronting major work on the health of the seas; at 100, he remains an active public voice for the planet.

At I Stand Beside, we feel his centenary as a moment to honour how across decades of broadcasting, Attenborough has returned, patiently and unsparingly, to the astonishing specificity of life on Earth: leafcutter ants, birds-of-paradise, gorillas, coral reefs, fungi, desert plants, bioluminescent creatures of the deep. He has not spoken of “nature” as an abstraction. He has introduced us to beings. He has helped people encounter the more-than-human world as presence, drama, community and kin.

In that sense, he may be the ultimate stand besider.

To stand beside is to notice closely, to communicate faithfully, to awaken care, and to use one’s gifts in service of life beyond the human. That is what he has done, at a scale few people in any century achieve. He has lent his voice, his craft, his patience and his credibility to the living world, again and again, helping others fall in love with it, defend it and grieve for what is being lost.

This month, the Royal Society described him as having devoted seven decades to inspiring and educating people about the Earth’s animals and plants. That is true, but it still feels insufficient to the scale of what he has offered. He has helped shape a culture in which the lives of other beings matter. He has enlarged public understanding of evolution, ecology and interdependence. At 100, Sir David Attenborough stands as witness to an age of immense loss, but also as proof that storytelling can alter what a society sees, values and protects. For that, and for so much else, we celebrate him with gratitude.

Happy 100th birthday, Sir David, and thank you for standing beside life.
