Life
Troughton was born at Corney, Cumberland, the youngest of six children to Francis Troughton, a husbandman on a farm, and his wife, Mary Stable. Originally raised to tend animals, Edward went to London in 1773.<ref>Template:Cite web</ref> He then served an apprenticeship with his uncle, John Troughton (b.c.1716), alongside his elder brother, also John Troughton, and in 1779 he became hisTemplate:Whose business partner. Troughton soon established himself as the top maker of navigational, surveying and astronomical instruments in Britain.<ref>Template:Cite journal</ref> They were based at 136 Fleet Street in central London. Their shop was called the "Sign of the Orrery".
In 1795 Troughton delivered what is now known as the Troughton equatorial telescope to the Armagh Observatory, a 2-inch aperture refractor telescope mounted equatorially, and its first major instrument since its founding in 1790.<ref>Template:Cite web</ref> He created the Groombridge Transit Circle in 1806, which Stephen Groombridge used to compile his star catalogue.<ref>Template:Cite web</ref> He did not merely build instruments, but designed and invented new ones.
Troughton was awarded the Copley Medal of the Royal Society in 1809. He was elected a Fellow of the Royal Society in March 1810,<ref>Template:Cite web</ref> a member of the American Philosophical Society in 1817,<ref>Template:Cite web</ref> and a Fellow of the Royal Society of Edinburgh in 1822.
In 1826, after John's death and in failing health himself, he took on William Simms as a partner, and the firm became known as Troughton & Simms.
Troughton was involved in a lawsuit against Sir James South, who was dissatisfied with the quality of an equatorial mounting that Troughton made for him. Troughton sued for payment, and with informal legal counsel provided by Richard Sheepshanks, he prevailed.<ref>Template:Cite web</ref>

He died in London on 12 June 1835<ref>Template:Cite web</ref> and was buried in Kensal Green Cemetery in south London.<ref name=Paths>Template:Cite book</ref> He was unmarried and had no children.
