John Canton, English physicist and academic (died 1772)

John Canton was a British physicist. He was born in Middle Street Stroud, Gloucestershire, to a weaver, John Canton and Esther. As a schoolboy, he became the first person to determine the latitude of Stroud, while making a sundial. The sundial caught the attention of many, including Dr Henry Miles, a Stroud-born Fellow of the Royal Society. Miles encouraged Canton to leave Gloucestershire to become a trainee teacher for Samuel Watkins, the headmaster of a Nonconformist school in Spital Square, London, with whom he ultimately entered into partnership.
