Lewis Carroll, the author of Alice's Adventures in Wonderland, was the pen name of Charles Dodgson, who taught and researched mathematics and also practiced photography.
The book's wordplay and disruptions of logic echo his interests. The popularity of his children's stories made his pen name better known than his birth name.
Literature
In March 1856, Dodgson published his first piece of work under the name that would make him famous. A romantic poem called "Solitude" appeared in The Train under the authorship of "Lewis Carroll". This pseudonym was a play on his real name: Lewis was the anglicised form of Ludovicus, which was the Latin for Lutwidge, and Carroll an Irish surname similar to the Latin name Carolus, from which comes the name Charles. The transition went as follows: "Charles Lutwidge" translated into Latin as "Carolus Ludovicus". This was then translated back into English as "Carroll Lewis" and then reversed to make "Lewis Carroll". This pseudonym was chosen by editor Edmund Yates from a list of four submitted by Dodgson, the others being Edgar Cuthwellis, Edgar U. C. Westhill, and Louis Carroll.
Alice books
In 1856, Dean Henry Liddell arrived at Christ Church at Oxford University, bringing with him his young family, all of whom would figure largely in Dodgson's life over the following years and would greatly influence his writing career. Dodgson became close friends with Liddell's wife, Lorina, and their children, particularly the three sisters Lorina, Edith, and Alice Liddell. He was widely assumed for many years to have derived his own "Alice" from Alice Liddell; the acrostic poem at the end of Through the Looking-Glass spells out her name in full, and there are also many superficial references to her hidden in the text of both books.
It has been noted that Dodgson himself repeatedly denied in later life that his "little heroine" was based on any real child, and he frequently dedicated his works to girls of his acquaintance, adding their names in acrostic poems at the beginning of the text. Gertrude Chataway's name appears in this form at the beginning of The Hunting of the Snark, and it is not suggested that this means that any of the characters in the narrative are based on her.
Information is scarce (Dodgson's diaries for the years 1858–1862 are missing), but it seems clear that his friendship with the Liddell family was an important part of his life in the late 1850s, and he grew into the habit of taking the children on rowing trips (first the boy, Harry, and later the three girls), accompanied by an adult friend, to nearby Nuneham Courtenay or Godstow. It was on one such expedition on 4 July 1862 that Dodgson invented the outline of the story that eventually became his first and greatest commercial success. He told the story to Alice Liddell and she begged him to write it down, and Dodgson eventually (after much delay) presented her with a handwritten, illustrated manuscript entitled Alice's Adventures Under Ground in November 1864.
Before this, the family of friend and mentor George MacDonald read Dodgson's incomplete manuscript, and the enthusiasm of the MacDonald children encouraged Dodgson to seek publication. In 1863, he had taken the unfinished manuscript to Macmillan the publisher, who liked it immediately. After the possible alternative titles were rejected – Alice Among the Fairies and Alice's Golden Hour – an expanded and substantially reworked version of the work was finally published as Alice's Adventures in Wonderland in 1865 under the Lewis Carroll pen name, which Dodgson had first used some nine years earlier. The illustrations this time were by Sir John Tenniel; Dodgson evidently thought that a published book would need the skills of a professional artist. Annotated versions provide insights into many of the ideas and hidden meanings that are prevalent in these books.
Recreational mathematics
The discovery in the 1990s of additional ciphers that Dodgson had constructed, in addition to his "Memoria Technica", showed that he had employed sophisticated mathematical ideas in their creation.
