Among the industries that owe their existence to technological innovation, voice communication by wire and by radio is an outstanding example. Professor Reich explains that during its first quarter century, however, the telephone enterprise developed a “business-technology mind-set” (he credits Reese Jenkins with the term) that held back further progress until after the thoroughgoing reorganization of American Telephone & Telegraph in 1907. Thereafter, an initial strong focus on applied science was gradually modified as the company sought to solve problems that stood in the way of important new services, such as long-distance telephony; to stay in the vanguard of major innovations, such as radio, that threatened the dominance of wired telephone systems; and to extend new capabilities into as many alternative techniques as necessary to “box the compass” of the patent laws. In the process, AT&T developed a highly structured research and development facility that pushed businessmen's respect for science and technology to new heights.

Espenschied was a laboratory engineer who, toward the end of his career, became interested in the history of research in the Bell System. With an eye for significant facts and a commitment to presenting the full story, Espenschied spent the years before and after his retirement examining company documents, communicating with former colleagues, and setting down the history of AT&T research as he saw it.

As long as all of the patents that the company had to deal with were “little” ones, there was no reason for concern; enough patent rights could be procured by AT&T that the remaining few would have little value, either to AT&T or to their holders.
