Neal Town Stephenson (born October 31, 1959) is an American writer known for his works of speculative fiction.
Difficult to categorize, his novels have been variously referred to as science fiction, historical fiction, cyberpunk, and postcyberpunk. Other labels such as 'baroque' often appear.
Stephenson explores areas such as mathematics, cryptography, philosophy, currency, and the history of science. He also writes non-fiction articles about technology in publications such as Wired.
He has worked part-time as an advisor for Blue Origin, a company (funded by Jeff Bezos) developing a manned sub-orbital launch system, and is also cofounder of Subutai Corporation, whose first offering is the interactive fiction project The Mongoliad. He has also written novels with his uncle, George Jewsbury ("J. Frederick George"), under the collective pseudonym Stephen Bury.
