Charles Lutwidge Dodgson (pronounced /ˈdɒdsən/; 27 January 1832 – 14 January 1898), better known by the pseudonym Lewis Carroll (/ˈkærəl/), was an English author, mathematician, logician, Anglican deacon and photographer. His most famous writings are Alice's Adventures in Wonderland and its sequel Through the Looking-Glass as well as the poems "The Hunting of the Snark" and "Jabberwocky", all examples of the genre of literary nonsense. He is noted for his facility at word play, logic, and fantasy, and there are societies dedicated to the enjoyment and promotion of his works and the investigation of his life in many parts of the world including the United States, Japan, the United Kingdom, and New Zealand.

Dodgson's family was predominantly northern English, with Irish connections. Conservative and High Church Anglican, most of Dodgson's ancestors were army officers or Church of England clergymen. His great-grandfather, also Charles Dodgson, had risen through the ranks of the church to become a bishop. His grandfather, another Charles, had been an army captain, killed in action in 1803 when his two sons were hardly more than babies. His mother's name was Frances Jane Lutwidge.

The elder of these sons—yet another Charles—was Carroll's father. He reverted to the other family business and took holy orders. He went to Rugby School, and thence to Christ Church, Oxford. He was mathematically gifted and won a double first degree, which could have been the prelude to a brilliant academic career. Instead he married his first cousin in 1827 and became a country parson.
