Edmond Halley astronomer and physicist (8 November 1656 - 14 January 1742). 1832 Engraving by W.D. Fry in the \Gallery of Portraits\" after the painting by Dahl 1736 at age 80 with later colouring. Halley published the first accurate catalogue of stars in the southern hemisphere in 1678, but is most famous for his deductions on comet periodicity. Halley recognised that the orbit of the comet he observed in 1682 was similar to the comets sighted in 1531 and 1607. He proposed that they were the same, and predicted its return in 1758. When it did, the comet was named after him. He served as Astronomer Royal, and was a Fellow of the Royal Society. His atheism prevented him becoming Savilian Professor of Astronomy in Oxford. Other achievements include the first diving bell, constructing mortality tables seen as a milestone in demography, and dating Stonehenge using scientific method."
