George Gilbert Aimé Murray, OM (2 January 1866 – 20 May 1957) was an Australian born British classical scholar and public intellectual, with connections in many spheres. He was an outstanding scholar of the language and culture of Ancient Greece, perhaps the leading authority in the first half of the twentieth century. He is the basis for the character of Adolphus Cusins in his friend Shaw's play Major Barbara, and also appears as the chorus figure in Tony Harrison's play Fram.
He was born George Gilbert Aimé Murray in Sydney, New South Wales, Australia. His father, Sir Terence Aubrey Murray, was a Member of the New South Wales Parliament who died in 1873; his mother, Agnes Ann Murray (née Edwards), ran a girls' school in Sydney for a few years. Then, in 1877, Agnes emigrated with Gilbert to the UK, where she died in 1891.
Gilbert was educated at Merchant Taylors' School and St John's College, Oxford.
