Blood Music was first published as a short story (1983) and then expanded to a novel (1985). It has also been credited as the first account of nanotechnology in science fiction. More certainly, the short story is the first in science fiction to describe microscopic medical machines and to treat DNA as a computational system capable of being reprogrammed; that is, expanded and modified. In later works, beginning with Queen of Angels and continuing with its sequel, Slant, Bear gives a detailed description of a near-future nanotechnological society. The historical sequence continues with Heads, which may contain the first description of a so-called "quantum logic computer", as well as Moving Mars. The sequence also charts the historical development of self-awareness in AIs. Its continuing character Jill was inspired in part by Robert A. Heinlein's self-aware computer Mycroft HOLMES (High-Optional, Logical, Multi-Evaluating Supervisor) in The Moon Is a Harsh Mistress.

In 1975, Bear married Christina M. Nielson; they divorced in 1981. In 1983, he married Astrid Anderson, the daughter of the science fiction and fantasy authors Poul and Karen Anderson. They have two children, Chloe and Alexandra. They reside near Seattle, Washington.

Bear was born in San Diego, California. He attended San Diego State University (1968–73), where he received a Bachelor of Arts degree. At the university, he was a teaching assistant to Elizabeth Chater in her course on science fiction writing, and in later years her friend.

Bear is often classified as a hard science fiction author because of the level of scientific detail in his work. Early in his career, he also published work as an artist, including illustrations for an early version of the Star Trek Concordance and covers for Galaxy and F&SF. He sold his first story, "Destroyers", to Famous Science Fiction in 1967.

One of Bear's favorite themes is reality as a function of observation. In Blood Music, reality becomes unstable as the number of observers (trillions of intelligent single-cell organisms) spirals higher and higher. Anvil of Stars (sequel to The Forge of God) and Moving Mars postulate a physics based on information exchange between particles, capable of being altered at the "bit level." (Bear has credited the inspiration for the idea to Frederick Kantor's 1967 treatise "Information Mechanics" (see Digital physics)) In Moving Mars, that knowledge is used to remove Mars from the solar system and transfer it to an orbit around a distant star.

Bear cites Ray Bradbury as the most influential writer in his life. He met Bradbury in 1967 and had a lifelong correspondence. As a teenager, Bear attended Bradbury lectures and events in Southern California.
