I was raised with the story of the heroic failure of Captain Robert Falcon Scott, Scott of the Antarctic, beaten to the South Pole by Amundsen, then dying so bravely in the frozen wastes. The film starring John Mills was a classic.
I also used to watch the naturalist Peter (later Sir Peter) Scott on wildlife programmes on TV, with no idea that he was actually the good Captain's son, born in 1909, and only a toddler when his father died.
Sir Peter was a great wildlife artist, too, and he was the leading light behind the formation of the World Wildlife Fund. A great man in a completely different way from his father, whom he can't have known, but whose legend he presumably grew up with.
Here he is presenting an amazing bird in the rainforest.
You can also hear his fascinating 10-minute "Life Stories" on BBC Radio4 each week, the latest of which is here: http://www.bbc.co.uk/iplayer/episode/b00mlxpv/David_Attenboroughs_Life_Stories_Birds_Nest_Soup/
