Arnold Walter Lawrence FBA (2 May 1900 – 31 March 1991) was a British authority on classical sculpture and architecture.

Arnold Lawrence was born at 2 Polstead Road, Oxford, on 2 May 1900, the youngest of five sons born to Thomas Chapman (who became, in 1914, Sir Thomas Chapman, 7th Baronet), an Anglo-Irish landowner from County Westmeath, and Sarah Junner (1861–1959).

[8] T. E.'s enduring fame was a burden for A. W.; from his early twenties until the day he died, many people saw A. W. Lawrence primarily as the brother of someone else.

[3] In 1951 he obtained a Leverhulme research fellowship for the study of ancient fortifications, a subject inherited from T. E. Lawrence.

In 1951 he resigned from his post at Cambridge to become the Professor of Archaeology at the University College of the Gold Coast where he established the National Museum and was the Secretary and Conservator of the Monuments and Relics Committee.

[1] In September 1985, when he and his wife could no longer drive, they moved to Langford, near Biggleswade, close to where their two grandchildren were living.
