Many readers thought that the story was a scientific report.
Robert Hanham Collyer, an English magnetic healer visiting Boston, wrote to Poe saying that he himself had performed a similar act to revive a man who had been pronounced dead (in truth, the man was actually a drunken sailor who was revived by a hot bath). Collyer reported of the story's success in Boston: "Your account of M. Valdemar's case has been universally copied in this city, and has created a very great sensation." Another Englishman, Thomas South, used the story as a case study in his book
Early Magnetism in its Higher Relations to Humanity, published in 1846. A Scottish reader named Archibald Ramsay wrote to Poe "as a believer in Mesmerism" asking about the story: "It details ...
most extraordinary circumstances", he wrote, concerned that it had been labeled a hoax. "For the sake of ... Science and of truth", he requested an answer from Poe himself. Poe's response was that "
Hoax is precisely the word suited. ... Some few persons believe it—but
I do not—and don't you." Poe received many similar letters, and replied to one such letter from a friend: "P.S. The 'Valdemar Case' was a hoax, of course." In the
Daily Tribune, its editor,
Horace Greeley, noted "that several good matter-of-fact citizens" were tricked by the story, but "whoever thought it a veracious recital must have the
bump of Faith large, very large indeed."
Elizabeth Barrett Browning wrote to Poe about the story to commend him on his talent for "making horrible improbabilities seem near and familiar". The Virginia poet
Philip Pendleton Cooke also wrote to Poe, calling the story "the most damnable, vraisemblable, horrible, hair-lifting, shocking, ingenious chapter of fiction that any brain ever conceived or hand traced. That gelatinous, viscous sound of man's voice! there never was such an idea before."
George Edward Woodberry wrote that the story, "for mere physical disgust and foul horror, has no rival in literature." James M. Hutchisson refers to the story as "probably Poe's most gruesome tale".
Rudyard Kipling, an admirer of Poe, references "The Facts in the Case of M. Valdemar" in his story "
In the House of Suddhoo", which suggests the disastrous results of the sorcery used by a man trying to save his sick son's life. One spell requires the head of a dead baby, which seems to speak. The narrator says, "Read Poe's account of the voice that came from the mesmerised dying man, and you will realise less than one half of the horror of that head's voice." ==Analysis==
