Bush chose to maintain his ties with the Navy after the war. It forced him to learn a new skill: the ability to embrace others unlike himself, a skill that would later prove immensely valuable. Bush served in the naval reserves for eight years, even as his career as an academic, an engineer, and a businessman grew. He was appointed a professor of engineering at MIT, invented one of the earliest computers (an analog machine), and helped launch a company that grew into the massive electronics manufacturer Raytheon.
