Researching Arthur Stone

Stone studied at Trinity College, Cambridge. His first paper dealt with squaring the square, he proved the Erdős–Stone theorem with Paul Erdős and is credited with the discovery of the first two flexagons, a trihexaflexagon and a hexahexaflexagon while he was a student at Princeton University in 1939. His Ph.D. thesis, Connectedness and Coherence, was written in 1941 under the direction of Solomon Lefschetz. He served as a referee for The American Mathematical Monthly journal in the 1980s.

The Stone metrization theorem has been named after him, and he was a member of a group of mathematicians who published pseudonymously as Blanche Descartes. He is not to be confused with American mathematician Marshall Harvey Stone.

He was born in Croydon, the son of George Thomas Stone and Jane Webb, and was educated there. Stone migrated to Canada in 1913 and was employed by the Grand Truck Railway (Pacific) which later became part of the Canadian National Railway. He became active in the railroad machinists' union. In 1921, he married Kathleen Walkling. Stone was president of the State Hospital and Medical League and played an important role in the implementation of medicare in Saskatchewan. He retired from the railway in 1960 and from politics in 1964.

His daughter, Barbara (Turnbull) Danaher (née Stone), was a noted Amateur golfer.

Stone's father and grandfather were Church of Ireland priests. He was educated at St Peter's School, York and Trinity College, Dublin. He was ordained deacon in 1875 and priest in 1876. After a curacy at Moreton-in-Marsh he served with the Indian Ecclesiastical Establishment at Ajmere, Cawnpore, Lucknow, Delhi, Mandalay and Darjeeling. In 1898, he was appointed a Fellow of the University of Calcutta. On his return from India he was Rector of Islip from 1902 to 1910, then Vicar of Burcombe.

He died on 11 January 1927.
