Edward Gorey had a unique point of view and a very dark sense of humour. He seemed to be very fond of word plays. He published some of his books under different pseudonyms which were actually anagrams of his own name. Some of them are feminine and he even has a pseudonym in German. Those names are, as a consequence of his dark and macabre sense, related to concepts that might be observed in Gorey's fiction. References that create a humorous yet still weird reality. Here is a list of his pseudonyms and books related to them.
