Sadly, the Galapagos notebook has never been seen since its disappearance from Darwin’s Kent home, Down House near Orpington. It is likely a visitor took the opportunity to steal the Galapagos book while they were on public display.
The naturalist’s great-great-grandson, Randal Keynes, said it was “almost certainly stolen”.
He said: “Our family always felt that the best Darwin material should be at Down House so that the public could see it in his home. The Galapagos notebook is of outstanding value for the history of science.
