Henry George Liddell (/ˈlɪdəl/;[a] 6 February 1811 – 18 January 1898) was dean (1855–1891) of Christ Church, Oxford, Vice-Chancellor of Oxford University (1870–1874), headmaster (1846–1855) of Westminster School[3] (where a house is now named after him), author of A History of Rome (1855), and co-author (with Robert Scott) of the monumental work A Greek–English Lexicon,[4] known as "Liddell and Scott", which is still widely used by students of Greek.
[5] As Headmaster of Westminster Liddell enjoyed a period of great success, followed by trouble due to the outbreak of fever and cholera in the school.
Coming just at the transition period when the "old Christ Church," which Pusey strove so hard to preserve, was inevitably becoming broader and more liberal, it was chiefly due to Liddell that necessary changes were effected with the minimum of friction.
[citation needed] In conjunction with Sir Henry Acland, Liddell did much to encourage the study of art at Oxford, and his taste and judgment gained him the admiration and friendship of Ruskin.
His father's elder brother, Sir Thomas Liddell, 6th Baronet (1775–1855), was raised to the Peerage as Baron Ravensworth in 1821.
