Laurence van Cott Niven's best known work is Ringworld (Ringworld, #1) (1970), which received the Hugo, Locus, Ditmar, and Nebula awards. His work is primarily hard science fiction, using big science concepts and theoretical physics. The creation of thoroughly worked-out alien species, which are very different from humans both physically and mentally, is recognized as one of Niven's main strengths. Niven also often includes elements of detective fiction and adventure stories. His fantasy includes The Magic Goes Away series, which utilizes an exhaustible resource, called Mana, to make the magic a non-renewable resource. Niven created an alien species, the Kzin, which were featured in a series of twelve collection books, the Man-Kzin Wars. He co-authored a number of novels with Jerry Pournelle. In fact, much of his writing since the 1970s has been in collaboration, particularly with Pournelle, Steven Barnes, Brenda Cooper, or Edward M. Lerner. 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, Topeka, Kansas, in 1962. He did a year of graduate work in mathematics at the University of California at Los Angeles. He has since lived in Los Angeles suburbs, including Chatsworth and Tarzana, as a full-time writer. He married Marilyn Joyce "Fuzzy Pink" Wisowaty, herself a well-known science fiction and Regency literature fan, on September 6, 1969. Niven won the Hugo Award for Best Short Story for Neutron Star in 1967. In 1972, for Inconstant Moon, and in 1975 for The Hole Man. In 1976, he won the Hugo Award for Best Novelette for The Borderland of Sol. Niven has written scripts for various science fiction television shows, including the original Land of the Lost series and Star Trek: The Animated Series, for which he adapted his early Kzin story The Soft Weapon. He adapted his story Inconstant Moon for an episode of the television series The Outer Limits in 1996. 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, which are unusual in comic books. http://us.macmillan.com/author/larryn...

"James Tiptree Jr." was born Alice Bradley in Chicago in 1915. Her mother was the writer Mary Hastings Bradley; her father, Herbert, was a lawyer and explorer. Throughout her childhood she traveled with her parents, mostly to Africa, but also to India and Southeast Asia. Her early work was as an artist and art critic. During World War II she enlisted in the Army and became the first American female photointelligence officer. In Germany after the war, she met and married her commanding officer, Huntington D. Sheldon. In the early 1950s, both Sheldons joined the then-new CIA; he made it his career, but she resigned in 1955, went back to college, and earned a Ph.D. in experimental psychology. At about this same time, Alli Sheldon started writing science fiction. She wrote four stories and sent them off to four different science fiction magazines. She did not want to publish under her real name, because of her CIA and academic ties, and she intended to use a new pseudonym for each group of stories until some sold. They started selling immediately, and only the first pseudonym—"Tiptree" from a jar of jelly, "James" because she felt editors would be more receptive to a male writer, and "Jr." for fun—was needed. (A second pseudonym, "Raccoona Sheldon," came along later, so she could have a female persona.) Tiptree quickly became one of the most respected writers in the field, winning the Hugo Award for The Girl Who was Plugged In and Houston, Houston, Do You Read?, and the Nebula Award for "Love is the Plan, the Plan is Death" and Houston, Houston. Raccoona won the Nebula for "The Screwfly Solution," and Tiptree won the World Fantasy Award for the collection Tales from the Quintana Roo. The Tiptree fiction reflects Alli Sheldon's interests and concerns throughout her life: the alien among us (a role she portrayed in her childhood travels), the health of the planet, the quality of perception, the role of women, love, death, and humanity's place in a vast, cold universe. The Otherwise Award (formerly the Tiptree Award) has celebrated science fiction that "expands and explores gender roles" since 1991. Alice Sheldon died in 1987 by her own hand. Writing in her first book about the suicide of Hart Crane, she said succinctly: "Poets extrapolate." Julie Phillips wrote her biography, James Tiptree, Jr.: The Double Life of Alice B. Sheldon
