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.

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.

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.
