His interest in electronics grew out of his in school-age hobby of amateur radio. Year later, working at Texas Instruments, he devised a way to miniaturize a complicated transistor circuit by building its components on a block of silicon with internal connections that eliminated external wiring. On 12 Sep 1958, he demonstrated his first integrated circuit to his supervisor. A few months later, an IC device in an improved form was independently invented elsewhere by Robert Noyce.
