Edward Smith-Stanley, 13th Earl of Derby
Edward Smith-Stanley, 13th Earl of Derby (21 April 1775 – 30 June 1851), KG, of Knowsley Hall in Lancashire (styled Lord Stanley from 1776 to 1832, known as Baron Stanley of Bickerstaffe from 1832-4), was a politician, peer, landowner, builder, farmer, art collector and naturalist. He was the patron of the writer Edward Lear.
He was educated at Eton College and Trinity College, Cambridge.  On 10 November 1796 he was appointed a Deputy Lieutenant of Lancashire  and in the same year he was elected as a Member of Parliament for Preston. He held this seat until 1812 and then represented Lancashire until 1832, when he was ennobled as Baron Stanley of Bickerstaffe, of Bickerstaffe in the County Palatine of Lancaster.
He was commissioned Colonel of the 1st Royal Lancashire Supplementary Militia on 1 March 1797;  this regiment subsequently became the 2nd Royal Lancashire Militia.  He was breveted as a colonel in the regular Army with seniority from that date, retaining the rank until his regiment was disembodied,  which occurred at the end of 1799.  He resigned his commission as colonel on 13 April 1847.
In 1834 he succeeded his father as 13th Earl of Derby and withdrew from politics, instead concentrating on his natural history collection at Knowsley Hall, near Liverpool. He had a large collection of living animals: at his death there were 1,272 birds and 345 mammals at Knowsley, shipped to England by explorers such as Joseph Burke. From 1828 to 1833 he was President of the Linnean Society. Many of Derby's collections are now housed in Liverpool's World Museum. Several species were named after him, for example the Derbyan parakeet, Psittacula derbiana and an Australian species of parrot named firstly by Nicholas Vigors as Platycercus stanleyii, in 1830 when he was Lord Stanley, and referred to in the vernacular as "The Earl of Derby’s Parrakeet" by the author John Gould in the sixth volume of his magnum opus Birds of Australia. However the latter species was found to have been named previously as Platycercus icterotis, and thus Platycercus stanleyii was found to have been an invalid name due to the pre-existence of a published description for the species, according to "the inviolable laws of precedence in deliberations on biological nomenclature".  From the Earl of Derby's Collection, the State Library of NSW purchased six volumes of exquisite Australian natural history drawings dating from the early days of British settlement in NSW and this Library publishes talks and exhibitions of its research on this collection. 
On 30 June 1798 he married his first cousin Charlotte Margaret Hornby (d.1817), second daughter of Rev. Geoffrey Hornby (1750-1812), of Scale Hall, near Lancaster  in Lancashire, High Sheriff of Lancashire in 1774 and a Deputy Lieutenant of Lancashire, Colonel of a regiment of Lancashire militia,  by his wife Lucy Smith-Stanley (d.1833) a daughter of James Smith-Stanley, Lord Strange (1716–1771), (son and heir apparent of Edward Stanley, 11th Earl of Derby (1689-1776)) and a sister of Edward Smith-Stanley, 12th Earl of Derby (1752-1834). Charlotte's brother was Edmund Hornby (1773-1857) of Dalton Hall, near Burton, Westmorland, a Member of Parliament for Preston, Lancashire, from 1812–1826,  who married his first cousin Lady Charlotte Stanley (d.1805), a daughter of Edward Smith-Stanley, 12th Earl of Derby (1752-1834).
