Edison's Conquest of Mars was published in 1898 as an unauthorized sequel to H. G. Wells' The War of the Worlds , but did not achieve the fame of its predecessor. It was commissioned by The New York Evening Journal . The book was endorsed by Thomas Edison, the hero of the book -- though not by Wells.

It is the first to portray a battle fought by space craft in the airless void; and possibly the first also to propose the use of sealed suits that enable men to traverse a vacuum.

Serviss showed a talent for explaining scientific details in a way that made them clear to the ordinary reader. Serviss' favorite topic was astronomy, and of the fifteen books he wrote, eight are devoted to it. He unquestionably was more widely read by the public on that topic than anyone prior to his time. He also wrote six works of fiction in his lifetime, all of which would today be classified as science fiction.
