Philip Kindred Dick (December 16, 1928 – March 2, 1982) was an American writer known for his work in science fiction. He produced 44 published novels and approximately 121 short stories, most of which appeared in science fiction magazines during his lifetime. His fiction explored varied philosophical and social themes, and featured recurrent elements such as alternate realities, simulacra, large corporations, drug abuse, authoritarian governments, and altered states of consciousness. His work was concerned with questions surrounding the nature of reality, perception, human nature, and identity.Born in Chicago, Dick moved to the San Francisco Bay Area with his family at a young age. He began publishing science fiction stories in 1951, at the age of 22. His stories initially found little commercial success, but his 1962 alternative history novel The Man in the High Castle earned Dick early acclaim, including a Hugo Award for Best Novel. He followed with science fiction novels such as Do Androids Dream of Electric Sheep? (1968) and Ubik (1969). His 1974 novel Flow My Tears, the Policeman Said won the John W. Campbell Memorial Award for Best Science Fiction Novel. Following a series of religious experiences in 1974, Dick's work engaged more explicitly with issues of theology, philosophy, and the nature of reality, as in novels A Scanner Darkly (1977) and VALIS (1981). A collection of his nonfiction writing on these themes was published posthumously as The Exegesis of Philip K. Dick (2011). He died in 1982 in Santa Ana, California, at the age of 53, due to complications from a stroke.
