Published in book form in 1895, The Time Machine is regarded as the best-known of Wells's “scientific romances” and one of the most influential stories about time travel ever written. Although the story was not the first to explore the concept of time travel, it is significant for its pseudoscientific explanation of how time travel could possibly occur. The novella initially appeared in serialized form as “The Chronic Argonauts” in Science School Journal in April 1888; it was then revised and published as The Time Machine in National Observer in 1894 and the New Review in January 1895. Wells revised the story again for the Atlantic Edition, which was published in 1924. Since its initial appearance in book form, The Time Machine has never gone out of print.
