Adam Parfrey was an American journalist, editor, and the publisher of Feral House books, whose work in all three capacities frequently centered on unusual, extreme, or "forbidden" areas of knowledge. A 2010 Seattle Weekly profile stated that "what Parfrey does is publish books that explore the marginal aspects of culture. And in many cases—at least back when his interests were almost exclusively transgressive—he sheds light on subjects that society prefers to leave unexplored, carving a niche catering to those of us with an unseemly obsession with life's darkest, most depraved sides."

Sydney Woodrow Parfrey was an American film and television actor from the 1950s to the early 1980s. He is often remembered as "one of TV's great slimeball villains".
