Hailsham of Saint Marylebone, Quintin McGarel Hogg, Baron (məgârˈəl, hālˈshəm əv sənt mârˈĭbōnˌ) [key], 1907–2001, British politician, b. London. A lawyer, he served (1938–50) as a Conservative member of Parliament for Oxford. In 1950, he succeeded his father as Viscount Hailsham and sat in the House of Lords, but in 1963 renounced the title for his lifetime and returned to the House of Commons, where he served until 1970. He was first lord of the admiralty (1956–57), deputy party leader and then leader in the House of Lords (1957–60 and 1960–63), and minister for science and technology (1959–64). With the encouragement of resigning prime minister Harold Macmillan, he contested (1963) Sir Alec Douglas-Home for the party leadership. Unsuccessful, he went back to his law career. He accepted a life peerage (1970) and served two terms as lord chancellor (1970–74, 1979–87). His writings include an autobiography, A Sparrow's Flight (1990), and two political works, The Purpose of Parliament (1946) and Science and Politics (1963).
