French novelist Jules Verne (1828~1905) is often called the father of science fictions.Although he was not a great traveller himself,his characters journeyed to the moon (in From Earth to Moon),Under the sea (in Twenty Thousand Leagues Under the Sea),into a volcano (in A Journey to the Centre of the Earth),around the world (in Around the World in Eighty Days) and to many other places.

Jules Verne was born in the French city of Nantes in 1828.When he was a boy he ran away from home to work on a ship.However,his father soon found him and brought him home.After that he decided that any future travel he did would be in books.In 1847,his father sent Jules to Paris to study to be a lawyer.Even though he was busy writing,Verne passed his exams in 1849 with high marks.

When Jules told his father he did not want to be a lawyer,his father was very angry.He stopped sending his son any money,so Jules had to earn a living by his writing.Over the next few years he wrote many stories and plays which brought him only a little money.Then,in 1856,he met Honorine de Viane,a rich,young widow with two children.The couple married the next year and their only child Michel was born in 1862.

After his marriage,Verne worked as a businessman in Paris.However,he was not very successful at his job and spent most of his time writing books and doing research for the next one.In 1863,he published his novel Five Weeks in a Balloon and in the following year he published A Journey to the Centre of the Earth which brought him fame.His books became so popular and earned him so much money that he was able to leave his job and work full time on his writing.
