Douglas C. Engelbart was 25, just engaged to be married and thinking about his future when he had an epiphany in 1950 that would change the world. In a single stroke he had what might be safely called a complete vision of the information age.
One of his inventions was given a warmhearted name, evoking a small, furry creature given to scurrying across flat surfaces: the computer mouse.
Dr. Engelbart died on Tuesday at 88 at his home in Atherton, Calif. His wife, Karen O’Leary Engelbart, said the cause was kidney failure.
