John O'Loughlin is a London-based author who was born in the Republic of Ireland of an English mother of mixed Irish descent and grew up first in Hampshire and then in Surrey, where he attended a variety of state schools. Most of his adult life has been spent at different addresses in the London Borough of Haringey, north of the River Thames, to which he moved from Surrey in 1974, and all but a few of his books have been written there, the majority of which are of an intensely philosophical nature.
