Serviss's favorite topic was astronomy, and most of the books he wrote are devoted to it. He unquestionably was more widely read by the public on that topic than anyone prior to his time. In his private life Serviss was an enthusiastic mountain climber, describing his reaching the summit of the Matterhorn at the age of 43 as part of an effort "to get as far away from terrestrial gravity as possible."
