Edgar Allan Poe (1809-1849) is one of America's greatest and best-loved writers.

Known as the father of the detective story, Poe is perhaps most famous for his short stories particularly his shrewd mysteries and chilling, often grotesque tales of horror he was also an extremely accomplished poet and a tough literary critic.

Poe's life was not far removed from the drama of his fiction. Orphaned at a young age, he was raised by a foster family. As a young man, he developed problems with gambling, debts, and alcohol, and was even dismissed from the army.

His love life was marked by tragedy and heartbreak. Despite these difficulties, Poe produced many works now considered essential to the American literary canon.

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.

Jack London (1876 - 1916), lived a life rather like one of his adventure stories. He was born John Chaney, the son of a travelling Irish-American fortune-teller and Flora Wellman, the outcast of a rich family. By the time Jack was a year old, Flora had married a grocer called John London and settled into a life of poverty in Pennsylvania. As Jack grew up he managed to escape from his grim surroundings into books borrowed from the local library - his reading was guided by the librarian.

At fifteen Jack left home and travelled around North America as a tramp - he was once sent to prison for thirty days on a charge of vagrancy. At nineteen he could drink and curse as well as any boatman in California! He never lost his love of reading and even returned to education and gained entry into the University of California. He soon moved on and in 1896 joined the gold rush to the Klondyke in north-west Canada. He returned without gold but with a story in his head that became a huge best-seller - The Call of the Wild - and by 1913 he was the highest -paid and most widely read writer in the world. He spent all his money on his friends, on drink and on building himself a castle-like house which was destroyed by fire before it was finished. Financial difficulties led to more pressure than he could cope with and in 1916, at the age of forty, Jack London committed suicide.

Titles such as The Call of the Wild, The Sea-Wolf and White Fang continue to excite readers today.

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.
