Edward Mordrake is the apocryphal subject of an urban legend who was, according to the legend, born in the 19th century as the heir to an English peerage with a face at the back of his head. According to legend, the face could only laugh or cry, with Mordrake begging doctors to remove it, claiming it whispered horrific things to him at night, before committing suicide at the age of 23.
An account described Mordrake's figure as one with "remarkable grace" and with a face similar to that of an Antinous. The second face on the back of Mordrake's head – supposedly female – reportedly had a pair of eyes and a mouth that drooled. The duplicate face could not see, eat or speak, but was said to "sneer while Mordrake was happy" and "smile while Mordrake was weeping". According to legend, Mordrake repeatedly begged doctors to have his "demon face" removed, claiming that at night, it whispered things that "one would only speak about in hell", but no doctor would attempt it. This then led to Mordrake secluding himself in a room before committing suicide at the age of 23.
An account of Mordrake's story was detailed in Anomalies and Curiosities of Medicine:
One of the weirdest as well as the most melancholy stories of human deformity is that of Edward Mordrake, said to have been heir to one of the noblest peerages in England. He never claimed the title, however, and committed suicide in his twenty-third year. He lived in complete seclusion, refusing the visits even of the members of his own family. He was a young man of fine attainments, a profound scholar, and a musician of rare ability. His figure was remarkable for its grace, and his face – that is to say, his natural face – was that of an Antinous. But upon the back of his head was another face, that of a beautiful girl, "lovely as a dream, hideous as a devil." The female face was a mere mask, "occupying only a small portion of the posterior part of the skull, yet exhibiting every sign of intelligence, of a malignant sort, however." It would be seen to smile and sneer while Mordrake was weeping. The eyes would follow the movements of the spectator, and the lips "would gibber without ceasing." No voice was audible, but Mordake avers that he was kept from his rest at night by the hateful whispers of his "devil twin", as he called it, "which never sleeps, but talks to me forever of such things as they only speak of in Hell. No imagination can conceive the dreadful temptations it sets before me. For some unforgiven wickedness of my forefathers I am knit to this fiend – for a fiend it surely is. I beg and beseech you to crush it out of human semblance, even if I die for it." Such were the words of the hapless Mordrake to Manvers and Treadwell, his physicians. In spite of careful watching, he managed to procure poison, whereof he died, leaving a letter requesting that the "demon face" might be destroyed before his burial, "lest it continues its dreadful whisperings in my grave." At his own request, he was interred in a waste place, without stone or legend to mark his grave.
The first known description of Mordrake is found in an 1895 Boston Post article authored by fiction writer Charles Lotin Hildreth. The article describes a number of cases of what Hildreth refers to as "human freaks", including a woman who had the tail of a fish, a man with the body of a spider, a man who was half-crab, and Edward Mordrake. Hildreth claimed to have found these cases described in old reports of the "Royal Scientific Society". It is unclear whether a society with this name existed. Like many publications of the time, Hildreth's article was not factual, and was likely published by the newspaper to increase reader interest. 
Anomalies and Curiosities of Medicine
The 1896 medical encyclopedia Anomalies and Curiosities of Medicine, co-authored by Dr. George M. Gould and Dr. David L. Pyle, included an account of Mordake. The account was copied directly from Hildreth's article, and was credited only to a "lay source". The encyclopedia described the basic morphology of Mordake's condition, but it provided no medical diagnosis for the rare deformity. An explanation for the birth defect may have been a form of craniopagus parasiticus (a parasitic twin head with an undeveloped body), a form of diprosopus (bifurcated craniofacial duplication), or an extreme form of parasitic twin (an unequal conjoined twin).
