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.

Jules Verne (1828-1905) was a French novelist and playwright best known for his epic adventures, including Twenty Thousand Leagues under the Sea, Journey to the Center of the Earth, and Around the World in Eighty Days.

A true visionary and master storyteller, Verne foresaw the skyscraper, the submarine, and the airplane, among many other inventions, and he is often regarded as the 'Father of Science Fiction.'

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.

Jonathan Swift (1667 – 1745) was a poet, satirist and clergyman; his parents were English but he was born in Dublin. His father died before he was born and his mother soon returned to England. Jonathan was brought up by his nurse in Cumbria and later by his Uncle Godwin back in Dublin. He was very unhappy as he was treated like the poor relative who had kindly been given a home. Jonathan went to Trinity College, Dublin where he was an unruly student and only just scraped through the examinations.

Through family connections he went to work in the home of Sir William Temple in Surrey, as secretary and later became both friend and editor. A young girl called Esther was also living in Sir William's house; she became Swift's closest friend and perhaps his wife. There is a mystery surrounding the relationship – Swift clearly loved her but we don't know whether or not they ever married.

Jonathan Swift's cousin, the poet John Dryden, told him he would never be a poet, but he soon became known as a poet and writer. He wrote many political pamphlets and was sometimes known as 'the mad parson'. He became dean of St Patrick's Cathedral in Dublin in 1713 and became popular in Ireland as a patriotic writer.

Swift was always afraid of madness and often suffered from depression; he suffered serious ill health in his last years. He wrote many volumes of prose and poetry but his best-known work is Gulliver's Travels in which he turned 'traveller's tales' into a biting satire on contemporary life. It has appealed to a wide range of readers over the years, including in its abridged form many children. As well as being a satire it is an exciting story, funny and very inventive.

Daniel Defoe was a Londoner, born in 1660 at St Giles, Cripplegate, and son of James Foe, a tallow-chandler. He changed his name to Defoe from c. 1695. He was educated for the Presbyterian Ministry at Morton's Academy for Dissenters at Newington Green, but in 1682 he abandoned this plan and became a hosiery merchant in Cornhill. After serving briefly as a soldier in the Duke of Monmouth's rebellion, he became well established as a merchant and travelled widely in England, as well as on the Continent.

Between 1697 and 1701 he served as a secret agent for William III in England and Scotland, and between 1703 and 1714 for Harley and other ministers. During the latter period he also, single-handed, produced the Review, a pro-government newspaper. A prolific and versatile writer he produced some 500 books on a wide variety of topics, including politics, geography, crime, religion, economics, marriage, psychology and superstition. He delighted in role-playing and disguise, a skill he used to great effect as a secret agent, and in his writing he often adopted a pseudonym or another personality for rhetorical impact.

His first extant political tract (against James II) was published in 1688, and in 1701 appeared his satirical poem The True-Born Englishman, which was a bestseller. Two years later he was arrested for The Shortest-Way with the Dissenters, an ironical satire on High Church extremism, committed to Newgate and pilloried. He turned to fiction relatively late in life and in 1719 published his great imaginative work, Robinson Crusoe. This was followed in 1722 by Moll Flanders and A Journal of the Plague Year, and in 1724 by his last novel, Roxana.

His other works include A Tour Through the Whole Island of Great Britain, a guide-book in three volumes (1724–6; abridged Penguin edition, 1965), The Complete English Tradesman (1726), Augusta Triumphans, (1728), A Plan of the English Commerce (1728) and The Complete English Gentleman (not published until 1890). He died on 24 April 1731. Defoe had a great influence on the development of the English novel and many consider him to be the first true novelist.

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.

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.
