David married his first love Jane Elizabeth Ebsworth Oriel in 1950. They were together for 47 and had two children, Susan and Robert, but Jane sadly died in 1997 after suffering a brain haemorrhage while David was filming in New Zealand.
Writing about Jane’s last moment in his memoirs Life on Air, David recalled how a doctor suggested he should hold her hand to see if she would clasp it back. “She did, and gave my hand a squeeze. The focus of my life, the anchor had gone…now I was lost,” he wrote.
When did David Attenborough receive his knighthood?
Queen Elizabeth II gave David a knighthood in 1985.
David's documentaries
His documentaries have undoubtedly fostered several generations worth of animal lovers, conservationists and natural historians, as well as giving the general public some of the best-loved moments of documentary telly.
Who could forget his 'wild' encounter with a family of mountain gorillas in January 1978 where these loveable apes stared on at him apathetically before rolling around on top of him like a play fight at school?
With his pioneering approach to film-making and landmark camera techniques, he has shown us animal interactions no one had even been privy to before, including ta sugar flight's stunning flight from Life on Earth or the moment naughty penguins show their criminal side as they steal stones.
But more than anything it's his down-to-earth good humour that make his shows such a joy to watch, seeing him howl away pretending to be a wolf or say boo to a sloth, both in The Life of Mammals. Even in moments many others might have considered scary he deals with it with fascinated glee, from the time a whale bobbed up next to his boat to his obvious glee, to the time he waded into a terrifying group of 'cannibals' in Papa New Guinea, only to greet them with a friendly, very English 'good afternoon'.
Aside from his television career, David has also written several dozen books as well as campaigning on countless environmental issues, including badger culling and plastic pollution.
