Daniel Defoe (1660—1731) was a famous English writer of the
eighteenth century (век). He wrote his world famous novel "The Life and
Strange Surprising Adventures of Robinson Crusoe" when he was nearly 60
years old.
The story of Robinson Crusoe was based on the real adventures of a sailor called Alexander Selkirk, who had lived alone for four years on a desert island. The book, however, also contains a lot of incidents from the author's imagination.
When the book was published in 1719, it immediately became popular. Defoe made his story so realistic that everyone believed it.
Defoe didn't write his book for children. But every child now knows
"Robinson Crusoe", how he learned to catch goats and to make pots, how
he made an umbrella and had hundreds of adventures.
Daniel Defoe wrote many other books, but for "Robinson Crusoe" he is called "the father of English prose".
