Harold James Ruthven Murray was the eldest son of Sir James Murray, the first editor of the Oxford English Dictionary, and as a schoolboy he helped his father by producing over 27,000 quotations for it. He read mathematics at Balliol College, Oxford, and worked as a schoolmaster, a headmaster and then a school inspector.
He learned chess as an adult and, encouraged in 1897 to research its history, spent thirteen years teaching himself Arabic and German and reading the world's great chess libraries. The result, A History of Chess (1913), proposed an Indian origin for the game and remains the most widely accepted account.
