Neal Town Stephenson is an American writer known primarily for his science fiction works in the postcyberpunk genre with a penchant for explorations of society, mathematics, cryptography, currency, and the history of science. He also writes non-fiction articles about technology in publications such as Wired Magazine, and has worked part-time as an advisor for Blue Origin, a company (funded by Jeff Bezos) developing a manned sub-orbital launch system. He has co-written two books with his uncle George F. Jewsbury under the joint pseudonym Stephen Bury.

Stephensons books tend to have elaborate, inventive plots drawing on numerous technological and sociological ideas at the same time. This distinguishes him from other mainstream science fiction authors who tend to focus on a few technological or social changes in isolation from others. The discursive nature of his writing, together with significant plot and character complexity and an abundance of detail, suggests a baroque writing style. In keeping with the baroque style, Stephensons books have become longer as he has gained recognition.
