While Joseph Merrick was alive, physicians believed that he suffered from a condition known as elephantiasis. In 1971 Ashley Montagu suggested that Joseph Merrick suffered from type 1 neurofibromatosis, a genetic disorder also known as von Recklinghausen's disease, and this disease is still connected with Joseph Merrick in the mind of the public. However, in 1979, Michael Cohen first identified a condition which came to be named Proteus syndrome by Rudolf Wiedemann in 1983. In 1986 it was argued that Proteus syndrome was the condition from which Joseph Merrick actually suffered. Proteus syndrome (named for the shape-shifting god Proteus), unlike neurofibromatosis, affects tissue other than nerves, and is a sporadic rather than familially transmitted disorder. In July 2003, Dr Charis Eng announced that as a result of DNA tests on samples of Merrick's hair and bone, he had determined that Merrick certainly suffered Proteus syndrome, and may have had type 1 neurofibromatosis as well.
