Mary Toft
Toft became pregnant in 1726, but later miscarried. She had developed a strong interest in a rabbit she had seen while working, and claimed to have given birth to parts of animals.  Local surgeon John Howard was called to see if it was true, and upon delivering several animal parts he told other important doctors.  The event came to the attention of Nathaniel St. André, surgeon to the Royal Household of King George I of Great Britain. St. André checked further into the event and decided that Toft was telling the truth. The king also sent surgeon Cyriacus Ahlers to see Toft, but Ahlers did not believe it.  By now quite famous, Toft was brought to London and was studied at length. She was watched closely. She produced no more rabbits, and eventually confessed to the hoax and was sent to prison as a fraud.
