Sir Arthur Conan Doyle was born in Edinburgh in 1859 and died in 1930. Within those years was crowded a variety of activity and creative work that made him an international figure and inspired the French to give him the epithet 'the good giant'.

He was the nephew of 'Dickie Doyle' the artist, and was educated at Stonyhurst, and later studied medicine at Edinburgh University, where the methods of diagnosis of one of the professors provided the idea for the methods of deduction used by Sherlock Holmes. He set up as a doctor at Southsea and it was while waiting for patients that he began to write.

His growing success as an author enabled him to give up his practice and turn his attention to other subjects. His greatest achievement was, of course, his creation of Sherlock Holmes, who soon attained international status and constantly distracted him from his other work; at one time Conan Doyle killed him but was obliged by public protest to restore him to life.

And in his creation of Dr Watson, Holmes's companion in adventure and chronicler, Conan Doyle produced not only a perfect foil for Holmes but also one of the most famous narrators in fiction.

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.

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.

Thomas Hardy was born in Dorset in 1840. His first published novel was Desperate Remedies in 1871. Such was the success of these early works, which included A Pair of Blue Eyes (1873) and Far From the Madding Crowd (1874), that he gave up his work as an architect to concentrate on his writing.

However, he had difficulty publishing Tess of the D'Urbervilles (1889) and was forced to make changes in order for it to be judged suitable for family readers. This, coupled with the stormy reaction to the negative tone of Jude the Obscure (1895), prompted Hardy to abandon writing novels altogether and he concentrated on poetry for the rest of his life. He died in January 1928.
