Raytheon: A History of Global Technology Leadership

''Two former college roommates Laurence K. Marshall and Vannevar Bush, along with scientist Charles G. Smith, founded Raytheon Company in Cambridge, Mass., as the American Appliance Company in 1922.''

''Throughout its more than 80-year history, Raytheon Company has been a leader in developing defense technologies and in converting those technologies for use in commercial markets. From its early days as a maker of radio tubes, its adaptation of World War II radar technology to invent microwave cooking, and its development of the first guided missile, Raytheon has successfully built upon its pioneering tradition to become a global technology leader.''
