[2] He attended Castle Park School in Dalkey, Dublin, Shrewsbury School in England, Magdalene College, Cambridge, then returned to Ireland where, persuaded by poet Patrick Kavanagh, he completed a doctorate at Trinity College Dublin on the works of the early 19th-century English poet Walter Savage Landor.
From 1952, he worked in London in the Inspectorate of Ancient Monuments,[5] but left in 1970 to join An Taisce in Dublin as its full-time executive secretary.
He donated his large collection to the Irish Architectural Archive in 2001,[6] and anthologies of his photos have been published in book form.
His third wife was actress and singer Agnes Bernelle, with whom he lived in Sandymount, Dublin, until her death in 1999.
