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.

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.

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.
