Lewis Carroll is a pseudonym of the Rev. Charles Lutwidge Dodgson, who was born on January 27, 1832, and died on January 14, 1898. His most famous works are Alice's Adventures in Wonderland; its sequel, Through the Looking-Glass and What Alice Found There; and The Hunting of the Snark. Martin Gardner (1914-2010) is regarded as one of the world's leading experts on Lewis Carroll and his work. The author of more than a hundred books, he wrote the "Mathematical Games" column for Scientific American for twenty-five years and has been hailed by Douglas Hofstadter as "one of the great intellects produced in this country in this century." The many works of Sir John Tenniel (1820-1914) include many humorous and political cartoons for Punch and other periodicals of the time, but he is best known for his illustrations of the original editions of Alice in Wonderland and Through the Looking Class.
