The Master Key An Electrical Fairy Tale Founded Upon The Mysteries Of Electricity And The Optimism Of Its Devotees. It Was Written For Boys, But Others May Read It by L. Frank Baum Vol. 5 in Project Gutenberg's L. Frank Baum-Series With the Wikipedia-Article on the Author. Lyman Frank Baum (May 15, 1856 - May 6, 1919) was an American author and the creator of one of the most beloved classics of children's literature, The Wonderful Wizard of Oz (more on L.F. Baum: http://en.wikipedia.org/wiki/Frank_Baum ). This non-Oz early SciFi shows all the new wonders of electricity, right to the absurd and utopian... Introduces the Demon of Electricity, who declares Edison and Tesla not to know a thing about matters... Mars not to be populated... and grants wishes to a boy-researcher who perchance came upon the "Master Key of Electritiy", which lead to many dangerous adventures around the globe! Great children's tale, great proto-SF-story.
