A Princess of Mars
The Barsoom series inspired a number of well-known 20th-century science fiction writers, including Jack Vance, Ray Bradbury, Arthur C. Clarke, Robert A. Heinlein, and John Norman. The series was also inspirational for many scientists in the fields of space exploration and the search for extraterrestrial life, including Carl Sagan, who read "A Princess of Mars" when he was a child.
