Parsons, William


(Third Earl of Rosse). Born June 17, 1800, in York; died Oct. 31, 1867, in Monkstown, Ireland. Irish astronomer. Member (1831) and president (1849–54) of the London Royal Society.

In 1845, Parsons constructed a reflecting telescope with a 182-cm mirror, which he set up at Birr Castle in Ireland. Using this telescope, he established the spiral structure of many extragalactic nebulae. Parsons was a member of the Royal Astronomical Society (1824) and a foreign member of the St. Petersburg Academy of Sciences (1852).
