Zenna Chlarson Henderson was born on November 1, 1917 in the Tucson, Arizona area. She graduated from Arizona State in 1940 with a Bachelors degree in education and worked as a teacher in Arizona throughout her life. She died on May 11, 1983, at the age of 65, in Tucson.
Henderson is known almost entirely for short stories about "The People." The People are a race of sensitive, human-looking aliens with psychic abilities who are separated after crash-landing on Earth but come to find each other over a period of many years.
Publishing her "People" stories in the leading science fiction magazines of the 50's, 60's and 70's, Henderson became a pioneer in many areas of science fiction literature. She was one of the first female science fiction writers, and was one of an even smaller number who wrote openly as a woman, without using male-sounding pseudonyms or initials (James Tiptree, Jr.; C.L. Moore; etc.).
Henderson was one of the first in science fiction to truly take young people seriously and write expressive, mature stories from their point of view. She drew on her experience as a teacher of young people, and was able to bring a rare level of insight to her use of young characters. Henderson's youthful protagonists are neither adults forced into young bodies, nor are they frivolous caricatures. They are very human, complete souls, yet marked by authentic signs of youth and innocence. Interestingly enough, Lois McMaster Bujold and Orson Scott Card, both of whom mention Henderson as an important early influence, have also been among the most successful chroniclers of young people, with such Hugo- and Nebula-award winning novels as Falling Free and Ender's Game.
Her books and stories about The People were the basis for the movie
The People, 1972, starring William Shatner and Kim Darby. Despite similarities, both Escape to Witch Mountain, 1975, and Return to Witch Mountain, 1978, were a result of books by Alexander Key.
