Charles Le Gai Eaton (Hasan le Gai Eaton or Hassan Abdul Hakeem) (1st January 1921-26th February 2010) was born in Lausanne, Switzerland. He received his education at Charterhouse and King’s College, Cambridge. He worked for many years as a teacher and journalist in Jamaica and Egypt. He then joined the British Diplomatic Service. Eaton converted to Islam in 1951. He served as a consultant to
the Islamic Cultural Centre in London.

His books include Islam and the Destiny of Man, King of the Castle, and The Richest Vein. Many converts to Islam in the United Kingdom have been inspired by his books, which are also expositions of Islam for Western readers, secular or believing.

For Eaton, Islam was above all else a means of leading a spiritual life, a life that is not dependent upon any of the transient institutional forms assumed by religion.
