Sir David Attenborough, the British naturalist and broadcaster, marks his 100th birthday on May 8, with events across the United Kingdom and beyond honouring a career spanning more than seven decades of natural history filmmaking. Fans are gathering at London's Trafalgar Square and Royal Albert Hall — where a 90-minute live show featuring archive footage and the BBC Concert Orchestra will pay tribute to his legacy — while the Natural History Museum runs an immersive 360° experience narrated by Attenborough through August 2026. Beginning with the landmark 1979 series Life on Earth and continuing through his 2025 documentary Ocean, Attenborough's work has been credited with reshaping how hundreds of millions of people worldwide understand and value the natural world, inspiring conservationists, filmmakers, and policymakers from Britain to India to take up its defence.
