William Buckland was an eminent palaeontologist and wrote the first full account of a dinosaur (Megalosaurus). He was also a zoöphage, and was obsessed with eating his way through the entire animal kingdom like a bloodthirsty version of Noah. Over the years, Buckland consumed panthers, crocodiles, mice on toast, a jaguar, and even bluebottle flies, which he found "repulsive." No shit.
This reclusive duke disliked social contact so much that he built a second, hidden underground mansion beneath his stately home, which was entirely painted pink and included an observatory and a vast ballroom with a huge hydraulic lift. He never organised any dances in the ballroom. He built a wide underground road that led from his mansion all the way to the town of Worksop, and food was sent to him on heated trucks that ran on rails through the underground tunnels.
