Dr Seward, the asylum superintendent in ‘Dracula’, decided to invent a new diagnosis for his pet patient Renfield – ‘zoophagy’ (animal-or life-eating).
However, Renfield wanted to go beyond his usual flies, spiders and birds, and attacked Dr Seward himself, explaining that ‘the blood is the life’ as mentioned in the Bible and in the advertisement shown above. (In fact this Mixture’s chief active ingredient was potassium iodide.)
The real psychiatrist Dr George Savage had in 1888 described a case with similar self-proclaimed motivation:
He visited the city abattoir, obtained and drank blood hot from the slaughtered animals. This was after a few days stopped, but fortunately he was watched, for he was seen to try to decoy children to his rooms, and he owned to me that he wished to have their blood, as blood was his life, and his life was that of a genius.
Dr Savage was considering the psychopathology of Jack the Ripper.
