Edward Geoffrey Smith Stanley, 14th Earl of Derby (1799-1869). British statesman and prime minister (1852, 1858-9, 1866-8), born at Knowsley Hall, Lancashire, NW England, UK. He studied at Oxford, entered parliament as a Whig in 1828, and became chief-secretary for Ireland (1830), and colonial secretary (1833), when he carried the Act for the emancipation of West Indian slaves. In 1834 he withdrew from the Party, and soon after joined the Conservatives (subsequently party leader, 1846-68). He entered the House of Lords as a baronet in 1844, retired from the cabinet in 1845, when Peel decided to repeal the Corn Laws, and in 1846 headed the Protectionists in the Lords. In 1851 he succeeded his father as Earl of Derby. Premier on three occasions, his third administration passed the Reform Bill (1867). (www.biography.com)
