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.

Guy de Maupassant was born in Normandy in 1850. In addition to his six novels, which include Bel-Ami (1885) and Pierre et Jean (1888), he wrote hundreds of short stories, the most famous of which is 'Boule de suif'.

By the late 1870s, he began to develop the first signs of syphilis, and in 1891 he was committed to an asylum in Paris, having tried to commit suicide. He died there two years later.

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.

Nathaniel Hawthorne was born in Salem, Massachusetts, where he wrote the bulk of his masterful tales of American colonial history.

His career as a novelist began with The Scarlet Letter (1850) and also includes The house of the Seven Gables, The Blithedale Romance, and The Marble Faun.

Kate Chopin was born in St Louis, Missouri on 8 Feb 1850. Born Katherine O'Flaherty, she grew up in a predominantly female household after her father died when she was just four years old. Her father was an Irish immigrant, and her mother was French Creole.

In 1870 she married Oscar Chopin, a local cotton trader, and together they had six children. In 1882 Oscar died from swamp fever, leaving Kate a widow with a large family to support, and the heir to his sizeable debts. She turned to writing in order to support her young family, publishing her first short story in 1889. A number of her works were subsequently published in literary magazines and popular American periodicals, including Vogue.

Chopin published only two novels in her lifetime: At Fault and The Awakening. The Awakening, published in 1899, was largely condemned as vulgar and immoral by critics of the time. Dismayed by such a harsh reception, Chopin cut short her brief career as a novelist, and for the remainder of her life focused solely on writing short stories, poetry and reviews. Kate Chopin died on 22 August 1904 from a brain haemorrhage.

Kate O'Flaherty was born on February 8, 1850, in St. Louis, of French and Irish ancestry. She was graduated from the St. Louis Academy of the Sacred Heart in 1868; two years later she married Oscar Chopin and went to live with him in New Orleans. They had five sons by 1878, and the following year they moved to Cloutierville, a tiny French village in Natchitoches Parish, in northwest Louisiana. There their last child and only daughter was born in 1879.

After Oscar's death in 1882, his widow ran their plantations and carried on a notorious romance with a married neighbour, but abruptly chose to return to St. Louis in 1884. Within five years she had begun her literary career, and during the next decade she published two novels - At Fault (1890) and The Awakening (1899) - and nearly a hundred short stories, poems, essays, plays and reviews.

Two volumes of short stories mostly set in the Cane River country of Louisiana, Bayou Folk (1894) and A Night in Acadie (1897) were acclaimed during her lifetime. But The Awakening, the story of a woman who has desires that marriage cannot fulfil, was widely condemned, and Chopin's publisher cancelled her third short-story collection, A Vocation and a Voice. Chopin died on August 22 1904.

Virginia Woolf was born in London in 1882. After her father's death in 1904 Virginia and her sister, the painter Vanessa Bell, moved to Bloomsbury and became the centre of ‘The Bloomsbury Group’. This informal collective of artists and writers exerted a powerful influence over early twentieth-century British culture.

In 1912 Virginia married Leonard Woolf, a writer and social reformer. Three years later, her first novel The Voyage Out was published, followed by Night and Day (1919) and Jacob's Room (1922). Between 1925 and 1931 Virginia Woolf produced what are now regarded as her finest masterpieces, from Mrs Dalloway (1925) to The Waves (1931).

She also maintained an astonishing output of literary criticism, short fiction, journalism and biography. On 28 March 1941, a few months before the publication of her final novel, Between the Acts, Virginia Woolf committed suicide.

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.

A veteran of the American Civil War who fought at Shiloh and Chickamauga in the Union ranks, Bierce became one of America's best-known writers and journalists, admired for his insolent, entertaining and sometimes courageous columns.

In 1913 he set off for Mexico, then in the throes of revolution, and was never seen again. Ralph Steadman is the author of many illustrated books including Sigmund Freud, I Leonardo, The Big I Am, The Scar-Strangled Banner, Alice and Animal Farm. His most recent publication is the novel, Doodaaa.

Robert Louis Stevenson (1850-94) was born in Edinburgh, Scotland. He studied law but preferred writing and in 1881 was inspired by his stepson to write Treasure Island.

Other famous adventure stories followed including Kidnapped, as well as the famous collection of poems for children, A Child's Garden of Verses. Robert Louis Stevenson is buried on the island of Samoa.

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.
