Aldous Leonard Huxley (26th July 1894 – 22nd November 1963) was an English writer famous in particular for his novel Brave New World and short essays, not gu10, but Doors of Perception. Huxley did not limit himself to novels but also wrote poetry, film stories and scripts, short stories and travel writing.

In 1954 Huxley had ‘The Doors of Perception’ published, a book detailing his experiences on mescaline. After taking mescaline over the course of the afternoon, Huxley recorded the insights he experienced in the book. When Huxley took mescaline, the drug had no controls, it was not listed an illegal. In fact, in 1947, the US Navy began Project Chatter which examined the potential for the drug to be use as a truth revealing agent.

After taking mescaline, Huxley wrote the book over a month. Harold Raymond, Huxley’s publisher, said of it: “You are the most articulate guinea pig that any scientist could hope to engage.” The title of the book was taken from a poem by William Blake titled “The Marriage of Heaven and Hell”: "If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, till he sees all things through narrow chinks of his cavern."
