It was probably in 1944 that I met David when we were both taking a shore course at the naval base near Kirkwall in the Orkney Islands. He was an junior RNVR officer, and of course his last name rang a bell with me. It turned out that he was, indeed, the younger brother of the noted film actor Richard Attenborough, who died in 2014. At the time, I just found it interesting to meet the younger brother of a famous actor. I had no inkling that David would soon be attaining his own fame as a broadcaster and naturalist.
