He was also a classic example of a British eccentric inventor, at one point he fashioned his own mercury delay lines for digital storage.

I have no trouble at all with the notion that he (foolishly) had a small unventilated room with cyanide, mercury, bismuth, probably a small kiln furnace for metal casting, floor to ceiling racks of odds and ends and semi regular small explosions and benchtop melt downs.

It's a lifestyle that's accidentally killed more than one person and it could very well have claimed Turing.
