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.

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.

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.
