Henry George Liddell (; 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 (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, known as "Liddell and Scott", which is still widely used by students of Greek. Lewis Carroll wrote Alice's Adventures in Wonderland for Henry Liddell's daughter Alice.

Life
Liddell received his education at Charterhouse and Christ Church, Oxford. He gained a double first degree in 1833, then became a college tutor, and was ordained in 1838.
Liddell was Headmaster of Westminster School from 1846 to 1855. Meanwhile, his life work, the great lexicon (based on the German work of Franz Passow), which he and Robert Scott began as early as 1834, had made good progress, and the first edition of Liddell and Scott's Lexicon appeared in 1843. It immediately became the standard Greek–English dictionary, with the 8th edition published in 1897.
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. In 1855 he accepted the deanery of Christ Church, Oxford. In the same year he brought out his History of Ancient Rome and took a very active part in the first Oxford University Commission. His tall figure, fine presence and aristocratic mien were for many years associated with all that was characteristic of Oxford life. 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.
