Dennis L. McKiernan

In 1977, while riding his motorcycle, McKiernan was hit by a car that had crossed the center-line, and he was confined to a bed, first in traction and then in a hip spica cast, for many months. During his recuperation, he began writing a sequel to J. R. R. Tolkien's The Lord of the Rings. The publisher Doubleday showed an interest in his work and tried to obtain authorization from Tolkien's estate but was denied. Doubleday then asked McKiernan to rewrite his story, placing the characters in a different fictitious world, and also to write a prequel supporting it. The prequel, of necessity, resembles The Lord of the Rings; the decision of Doubleday to issue the work as a trilogy increased that resemblance; and some critics have seen McKiernan as simply imitating Tolkien's epic work. McKiernan has subsequently developed stories in the series that followed along a story line different from those that plausibly could have been taken by Tolkien.

McKiernan was born in Moberly, Missouri, where he lived until he served the U.S. Air Force for four years, stationed within US territory during the Korean War. After military service, he attended the University of Missouri and received a BS in electrical engineering in 1958 and an MS in the same field from Duke University in 1964. He worked as an engineer at AT&T, initially at Western Electric but soon at Bell Laboratories, from 1958 until 1989. In 1989, after early retirement from engineering, McKiernan began writing on a full-time basis.

Dennis Lester McKiernan (born April 4, 1932) is an American writer best known for his high fantasy The Iron Tower. His genres include high fantasy (set in various fictitious worlds), science fiction, horror fiction, and crime fiction. His primary setting, Mithgar, was originally meant to host Middle-Earth stories that were sequels to Tolkien's work. It has since grown to reflect a much broader variety of influences, including "fairy tales and Oz books and folk tales and other such stories".
