Burroughs (1875-1950), author of some 70 books, was one of the commercially successful authors of the 20th century.

He wrote what would today be called science fantasy.

Burroughs is probably best known today as the author of Tarzan of the Apes (1912)

However, A Princess of Mars (1912), his first published story, introduced Barsoom (Mars) and brought interplanetary adventure into science fiction to stay.

At the Earth's Core (1914) introduced Pellucidar, where the hollow Earth lit by a miniature sun harbors savage tribes and fantastic creatures.

Burroughs also wrote:

• Pirates of Venus (1932) and sequels
• The Moon Maid (1923) and sequels
• The Land That Time Forgot (1924) and sequels
