Edward Joshua Cooper

Edward Joshua Cooper (May 1798 – 23 April 1863)^[1] was an Irish landowner, politician and astronomer from Markree Castle in County Sligo. He sat in the House of Commons of the United Kingdom from 1830 to 1841 and from 1857 to 1859, but is best known for his astronomy, and as the creator of Markree Observatory.

His observatory was home to the largest refracting (telescope with a lens) of the 1830s (an almost 14 inch astronomical grade Cauchoix of Paris lens, the largest in the World), and the asteroid 9 Metis was discovered there in the 1840s by his assistant. Several astronomical catalogs were also produced in the 19th century there.
