Autographs of Michael Berryman
Michael John Berryman (born September 4, 1948) is an American character actor. Berryman was born with hypohidrotic ectodermal dysplasia, a rare condition characterized by the absence of sweat glands, hair, and fingernails; his unusual physical appearance has allowed Berryman to make a career out of portraying characters in a number of cult films, horror films and B movies. He first came to prominence for his roles in Miloš Forman's One Flew Over the Cuckoo's Nest (1975) and Wes Craven's The Hills Have Eyes (1977). He has appeared in a wide range of feature films and television series, including Star Trek, The X-Files, and Highway to Heaven, in which he portrayed Satan.
Michael John Berryman was born September 4, 1948, in Los Angeles, California, the second of two children of Sloan and Barbara Berryman. He has one elder sister, Virginia. Berryman is of partial German descent; his German great-grandfather was a doctor who worked in Vienna. Berryman's mother was a nurse, and his father was a U.S. Navy neurosurgeon who was deployed to the Hiroshima fallout zone in the wake of the atomic bombing.
Due to his father's exposure to radiation, Berryman was born with hypohidrotic ectodermal dysplasia, a rare genetic condition that affects the development of sweat glands, skin, hair, and fingernails. The condition also led Berryman to develop craniosynostosis, requiring him to undergo cranial reconstructive surgery as a child.
