David was born in 1926, the same year as Barbara and Queen Elizabeth. We met at a shore course at a naval base near Kirkwall in the Orkney Islands.
He was the younger brother of Richard Attenborough, who had made his name as an actor in the film In Which We Serve. Richard died in 2014, but David is still alive as I write.
I was a Midshipman at the time, probably in 1944, when we met. I liked David, and have followed his career with interest.
He has achieved considerable fame as a naturalist, and was knighted in 1985. He also received the prestigious award of Companion of Honour CH.
