Charles Dickens was born in 1812 and became the most popular novelist of the Victorian era.

A prolific writer, he published more than a dozen novels in his lifetime, including Oliver Twist, Great Expectations and Hard Times, most of which have been adapted many times over for radio, stage and screen.

Hans Christian Andersen was born in Odense, Denmark, in 1805. His Fairy Tales, the first children's stories of their kind, which were published in instalments from 1835 until his death in 1875, have been translated into more than a hundred languages and adapted for every kind of media.

When Jacob and Wilhelm Grimm set out to collect stories in the early 1800s, their goal was not to entertain children but to preserve Germanic folklore and the hard life of European peasants was reflected in the tales they discovered.

However, once the brothers saw how the stories entranced young readers, they began softening some of the harsher aspects to make them more suitable for children.

Louisa May Alcott was born on 29 November 1832 in Pennsylvania, and she grew up with plenty of books to read but seldom enough to eat. Louisa went to work when she was very young as a paid companion and teacher, but she loved writing most of all, and like Jo March she started selling sensational stories in order to help provide financial support for her family.

She worked as a nurse during the American Civil War but the experience made her extremely ill. Little Women was published in 1868 and was based on her life growing up with her three sisters. She followed it with three sequels, Good Wives (1869), Little Men (1871) and Jo's Boys (1886) and she also wrote other books for both children and adults. Louisa was also a campaigner for women's rights and the abolition of the slave trade. She died on 6 March 1888.

O. Henry (1862-1910) had a short but colourful life. Born William Porter in Greensboro, North Carolina, he initially worked as a pharmacist before moving into journalism. In 1896 he was arrested for embezzling funds while working as a bookkeeper for a bank.

In a moment of madness, he absconded on his way to the courthouse before his trial and fled to Honduras for six months. He returned to face trial after learning that his wife was dying of tuberculosis and served three years in jail. While in prison, he adopted the pen name O. Henry, and after his release he found great fame and popularity as a short story writer.
