Larry Niven is an American science fiction writer. His best-known works are Ringworld (1970), which received Hugo, Locus, Ditmar, and Nebula awards, and, with Jerry Pournelle, The Mote in God's Eye (1974) and Lucifer's Hammer (1977). The Science Fiction and Fantasy Writers of America named him the 2015 recipient of the Damon Knight Memorial Grand Master Award. His work is primarily hard science fiction, using big science concepts and theoretical physics. It also often includes elements of detective fiction and adventure stories. His fantasy includes the series The Magic Goes Away, rational fantasy dealing with magic as a non-renewable resource. He is a great-grandson of Edward L. Doheny, an oil tycoon who drilled the first successful well in the Los Angeles City Oil Field in 1892 and was subsequently implicated in the Teapot Dome scandal. He briefly attended the California Institute of Technology and graduated with a Bachelor of Arts in mathematics (with a minor in psychology) from Washburn University in Topeka, Kansas in 1962. He also completed a year of graduate work in mathematics at the University of California, Los Angeles. On September 6, 1969, he married Marilyn Wisowaty, a science fiction and Regency literature fan. Niven has written scripts for three science fiction television series: the original Land of the Lost series; Star Trek: The Animated Series, for which he adapted his early story The Soft Weapon, and The Outer Limits, for which he adapted his story Inconstant Moon into an episode of the same name. He has also written for the DC Comics character Green Lantern, including in his stories hard science fiction concepts such as universal entropy and the redshift effect.
