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, and film stories and scripts. Huxley spent the later part of his life in the United States, living in Los Angeles from 1937 until his death.

Aldous Huxley was a humanist, pacifist, and satirist, and he was latterly interested in spiritual subjects such as parapsychology and philosophical mysticism. He is also well known for advocating and taking psychedelics.

By the end of his life Huxley was considered, in some academic circles, a leader of modern thought and an intellectual of the highest rank, and highly regarded as one of the most prominent explorers of visual communication and sight-related theories as well.
