De Wikipedia: Johann David Wyss (28 May 1743 – 11 January 1818) was a Swiss author, best remembered for his book The Swiss Family Robinson (Der schweizerische Robinson) (1812). He was born and died in Bern. It is said that he was inspired by Daniel Defoe's Robinson Crusoe, but wanted to write a story from which his own children would learn, as the father in the story taught important lessons to his children. The Swiss Family Robinson was first published in German in 1812, then translated into English two years later. It has since become one of the most popular books of all time.[citation needed] The book was edited by his son, Johann Rudolf Wyss, a scholar known for writing the Swiss national anthem, Rufst du, mein Vaterland. Another of Wyss's sons, Johann Emmanuel Wyss, illustrated the book. Johann David Wyss died in 1818 at the age of 74. He lived longer than his son Johann Rudolf, who would die twelve years later at the age of 48.
Wyss has been described as an author whose style was "firmly Christian and moral in tone". There are also many underlying tones of Christianity throughout the book, particularly with regard to many of the characters and their moral philosophies.
