John Bevis
John Bevis (10 November 1695 in Salisbury, Wiltshire – 6 November 1771) was an English doctor, electrical researcher and astronomer. He is best known for discovering the Crab Nebula in 1731. He was educated at Christ Church, Oxford, being awarded his B.A. in 1715 and his M.A. in 1718. In 1757 Bevis published in London a volume on The History and Philosophy of Earthquakes in which he collected accounts of the 1755 Lisbon earthquake from diverse authentic sources. His survey, the first of its kind, was subsequently used by John Michell (1761). In 1757 Bevis was asked by the tobacconist Thomas Hughes to discover why no flowers would grow in his garden at Bagnigge House, which stood in the vicinity of 61–63 King's Cross Road, London. He found the water from the well on the site to be full of iron. On this research, a second well was dug, the water from which was found to be a good purgative. This led to the establishment of one of the most popular 18th-century spas, Bagnigge Wells, the following year. He was elected a Fellow of the Royal Society in November, 1765. (Wikipedia).
