According to Wikipedia: "Garrett Putnam Serviss (1851-1929) was an astronomer, popularizer of astronomy, and early science fiction writer. Serviss was born in upstate New York, and majored in science at Cornell. He took a law degree at Columbia, but never worked as an attorney. Instead, in 1876 he joined the staff of the New York Sun newspaper, working as a journalist until 1892 under editor Charles Dana. Serviss showed a talent for explaining scientific details in a way that made them clear to the ordinary reader, leading Andrew Carnegie to invite him to deliver The Urania Lectures in 1894 on cosmology, astronomy, geology, and related matters. With Carnegie's financial backing, these lectures were illustrated with magic lantern slides and other effects to show eclipses, presumed lunar landscapes, and much else. Serviss toured the United States for over two years delivering these lectures, then settled down to become a popular speaker in the New York area. He wrote a syndicated newspaper column devoted to astronomy and other sciences. He also wrote frequently for the leading magazines of the day."
