Please answer the following question: Information: - Gray Lensman is a science fiction novel by author E. E. Smith . It was first published in book form in 1951 by Fantasy Press in an edition of 5,096 copies . The novel was originally serialized in the magazine Astounding in 1939 . Gray Lensman is the fourth ( originally the second ) book in the classic Lensman series and the second to focus on the adventures of Lensman extraordinaire Kimball Kinnison . While the novel is colored by 1930s sensibilities , it remains an exciting space opera complete with iron - nerved heroes , bizarre aliens , scheming villains , and colossal space battles . - Lloyd Arthur Eshbach (June 20, 1910 October 29, 2003) was an American science fiction fan, publisher and writer, secular and religious publisher, and minister. - Science fiction (often shortened to SF, sci-fi or scifi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction. - Time travel is the concept of movement (such as by a human) between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in philosophy and fiction, but traveling to an arbitrary point in time has a very limited support in theoretical physics, and usually only in conjunction with quantum mechanics or wormholes, also known as Einstein-Rosen bridges. In a more narrow sense, one-way time travel into the future via time dilation is a well-understood phenomenon within the frameworks of special relativity and general relativity, but advancing a large amount of time is not feasible with current technology. The concept was touched upon in various earlier works of fiction, but was popularized by H. G. Wells' 1895 novel "The Time Machine", which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction. - Edward Elmer Smith (also E. E. Smith, E. E. Smith, Ph.D., E. E. "Doc" Smith, Doc Smith, "Skylark" Smith, orto his familyTed; May 2, 1890 August 31, 1965) was an American food engineer (specializing in doughnut and pastry mixes) and an early science-fiction author, best known for the "Lensman" and "Skylark" series. He is sometimes called the father of space opera. - Fantasy Press was an American publishing house specialising in fantasy and science fiction titles. Established in 1946 by Lloyd Arthur Eshbach in Reading, Pennsylvania, it was most notable for publishing the works of authors such as Robert A. Heinlein and E. E. Smith. One of its more notable offerings was the Lensman series. What is the relationship between 'gray lensman' and 'edward elmer smith'?
