Charles Darwin
Yes, have always been a huge fan of Charlie Darwin and indeed celebrate his birthday every year on 12th February.
And this prompted a long-term desire to travel to the Galapagos Islands, visit his house in the UK and inspect the many statues and references around the World.
But being ecumenical about the 'discovery' of natural selection, I'm also a big fan of his co-discoverer (and not properly recognised), Russel Alfred Wallace. We made the journey to visit his house at Ternate (Spice Islands, northern Indonesia) where he did much of his research.
