Harold James Ruthven Murray (24 June 1868 – 16 May 1955) was an English educationalist, inspector of schools, and prominent chess historian. He was the first to publish the theory that chess originated in India.
Murray, the eldest of eleven children, was born near Peckham Rye in Peckham, London. The son of Sir James Murray, the first editor of the Oxford English Dictionary, he attended school at Mill Hill and during his spare time helped his father produce the first edition of the OED. By the time Harold had finished school and was preparing to leave for university, he had been responsible for over 27,000 quotations that later appeared in the OED.
He won a place at Balliol College, Oxford where in 1890 he graduated with a first class degree in Mathematics. He became an assistant master at Queen's College, Taunton where he learned to play chess. Later he was assistant master at Carlisle Grammar School and in 1896 he became headmaster of Ormskirk Grammar School in Lancashire. On 4 January 1897 he married Miss Kate Maitland Crosthwaite. In 1901, he was appointed a school inspector and in 1928 he became a member of the board of education.
Murray was a champion of the left-handed, defending children against the attempts of schools to make them conform by using their right hand.
In 1897 he was encouraged by Baron von der Lasa (who had just completed his book on the history of European chess) to research into the further past of chess. Murray gained access to the largest chess library in the world, that of John G. White of Cleveland, Ohio, and also used the collection of J. W. Rimington Wilson in England. The White collection contained some Arabic manuscripts, so Murray learnt Arabic (in addition to his native English and German) and examined many historical chess documents. The research took him 13 years, and he contributed articles on aspects of chess history to the British Chess Magazine and the Deutsches Wochenschach in this time. In 1913 he published his most significant work, A History of Chess, proposing the theory that chess originated in India. This remains the most widely accepted theory today. (See Origins of chess.)
