Edward Page Mitchell (1852-1927) was an American editorial and short story writer for The Sun, a daily newspaper in New York City, for which he wrote a series of fantasy and science fiction stories popular in his day. Never collected in a single volume during his lifetime, his name and stories were forgotten until they were rescued from the newspaper archives. Mitchell's stories were written between the 1870s and 1880s, so Mitchell was ahead of H. G. Wells himself, hence becoming a pioneer. This volume includes stories that can be described as Science Fiction and in which the reader will find a whole series of topics that would later become constants within the genre: time travel, cryogenics, teleportation, artificial intelligence or invisibility.
