Aldous Leonard Huxley (26 July 1894 – 22 November 1963) was an English writer and one of the most prominent members of the famous Huxley family. Best known for his novels including Brave New World and a wide-ranging output of essays, Huxley also edited the magazine Oxford Poetry, and published short stories, poetry, travel writing, film stories and scripts. He spent the later part of his life in the United States, living in Los Angeles from 1937 until his death.

Huxley was a humanist, pacifist, and satirist. He later became interested in spiritual subjects such as parapsychology and philosophical mysticism, in particular Vivekanda's Neo-Vedanta and Universalism. He is also well known for his advocacy and consumption of psychedelic drugs.

By the end of his life Huxley was widely acknowledged as one of the pre-eminent intellectuals of his time.
