Lyman Frank Baum, born May 15 1856, was an American author of children's books, best known for writing The Wonderful Wizard of Oz. He wrote thirteen novel sequels, nine other fantasy novels, and a host of other works (55 novels in total, plus four "lost" novels, 83 short stories, over 200 poems, an unknown number of scripts, and many miscellaneous writings), and made numerous attempts to bring his works to the stage and screen.

His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high risk, action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).

On May 5, 1919, Baum suffered from a stroke. He died quietly the next day, nine days short of his 63rd birthday.His final Oz book, Glinda of Oz, was published on July 10, 1920, a year after his death. The Oz series was continued long after his death by other authors, notably Ruth Plumly Thompson, who wrote an additional nineteen Oz books.

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.

Samuel Langhorne Clemens, better known by his pen name, Mark Twain, was born on November 30, 1835, in the tiny village of Florida, Missouri.

Writing grand tales about Tom Sawyer, Huckleberry Finn and the mighty Mississippi River, Mark Twain explored the American soul with wit, buoyancy, and a sharp eye for truth. He became nothing less than a national treasure.

Lucy Maud Montgomery was born on Prince Edward Island, Canada, in 1874. Anne of Green Gables, published in 1908, was her first novel and has remained in print across the world ever since. Montgomery died in Toronto in 1942.

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.

Willa Cather was born in Virginia in 1873 and moved to Nebraska, with its wide open plains and immigrant farming communities, at the age of nine.

This landscape would deeply affect her later writing. She attended university and became a journalist and teacher in Pittsburgh, and then a magazine editor in New York.

Her first major novel, O Pioneers!, appeared in 1913, and was followed by two more in her prairie trilogy: The Song of the Lark and My Antonia. She lived with the editor Edith Lewis for thirty-nine years until her death in 1947.

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.

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.

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.

Ernst Theodor Amadeus Hoffmann (1776–1822) replaced his third name, Wilhelm, with Amadeus in homage to Mozart. A towering figure of German Romanticism, Hoffmann was a composer, music critic, theater director, draftsman, and caricaturist as well as a writer. Although his stories challenged readers to free their minds from the conventions of reality, Hoffmann accepted the practical constraints of everyday life, training as a lawyer and serving as a judge.

The brilliant Russian novelist Fyodor Dostoyevsky (1821–81) is celebrated for such classics as Crime and Punishment and The Brothers Karamazov whose psychological examinations of the human soul had a profound effect on the 20th-century novel. His influence resonates in the works of such latter-day authors as Proust, Faulkner, Hemingway, and Kafka. Dostoyevsky also wrote many shorter works that are masterpieces in their own right.
