All his life, Charles Dodgson loved entertaining children. At the age of 30, he spent a lot of time with the Liddell girls — Lorina, Edith and his favourite, Alice. He often photographed them, played 'nonsense' games with them, and told them long stories.
On a sunny afternoon in July 1862, Charles Dodgson and a friend took* the Liddell girls rowing on the River Thames near Oxford. The children asked Dodgson to tell them a fairy tale, and 10-year-old Alice Liddell said* she hoped the story would have "nonsense" in it. So Dodgson told them an amazing tale, full of nonsense, about a little girl called Alice and her adventures in a magical underground world. Alice liked the story so much that she said, "I wish you would write out Alice's adventures for me!"
Dodgson wrote down the story, drew* pictures for it, put* a photograph of Alice Liddell on the last page and gave the 'book' to her. Later Dodgson made* some changes to the story and published the book as Alice's Adventures in Wonderland in 1865. The book was soon a success, and Dodgson wrote Through the Looking-Glass in 1871, based on more stories he told the Liddell girls. When Dodgson died in 1898, Alice was already the most popular children's book in England. Translated into dozens of languages, it became — and still is today — one of the most popular and most famous in the world.
