Asimov was born sometime between October 4, 1919 and January 2, 1920 in Petrovichi in Smolensk Oblast, RSFSR (now Russia), the son of a Jewish family of millers.  Although his exact date of birth is uncertain, Asimov himself celebrated it on January 2.  His family emigrated to Brooklyn, New York and opened a candy store when he was three years old.  He taught himself to read at the age of five. He began reading the science fiction pulp magazines that his family's store carried. Around the age of eleven, he began to write his own stories, and by age nineteen, he was selling them to the science fiction magazines. He graduated from Columbia University in 1939. He married Gertrude Blugerman in 1942.  During World War II he worked as a civilian at the Philadelphia Navy Yard's Naval Air Experimental Station.  After the war, he returned to Columbia University and earned a Ph.D. in biochemistry in 1948.  He then joined the faculty of the Boston University School of Medicine until 1958, when he became a full-time writer. His first novel, [Pebble in the Sky](https://openlibrary.org/works/OL46402W), was published in 1950. He and his wife divorced in 1973, and he married Janet O. Jeppson the same year. He was a highly prolific writer, having written or edited more than 500 books and an estimated 9,000 letters and postcards. || Martin Harry Greenberg (March 1, 1941 – June 25, 2011) was an American academic and anthologist in many genres, including mysteries and horror, but especially in speculative fiction. In all, he compiled 1,298 anthologies and commissioned over 8,200 original short stories. He founded Tekno Books, a packager of more than 2000 published books. He was also a co-founder of the Sci-Fi Channel. Greenberg was also an expert in terrorism and the Middle East. He was a longtime friend, colleague and business partner of Isaac Asimov. || Alfred Elton van Vogt was born on a farm in Edenburg, a Russian Mennonite community east of Gretna, Manitoba. Early in his career he wrote for true confession pulp magazines like True Story, but in the late 1930s he began writing science fiction, which he was more interested in. His first published SF story, "Black Destroyer" was published in 1939, and is considered to be one of the first works of the Golden Age of science fiction. In 1941 he left his job at the Department of National Defence to become a full-time writer, and he went on to write a large number of short stories. In 1944 he moved to Hollywood, California. In the 1950s he briefly became involved in L. Ron Hubbard's Dianetics projects. Although he left Dianetics, he claimed that Hubbard's followers continued to harass him, and he stopped writing for a few years. In the 1960s Frederik Pohl convinced him to start writing again, and he wrote novels (as opposed to short stories that were later developed into novels) until his death in 2000. || English science fiction writer || A science fiction writer and fan from Northern Ireland, noted for his originality and wit. He won the Hugo Award for Best Fan Writer in 1979 and 1980. His short story "Light of Other Days" was a Hugo Award nominee in 1967, as was his novel *The Ragged Astronauts* in 1987. || Philip Kindred Dick was an American novelist, short story writer, and essayist whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug abuse, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly and VALIS.
