Kurzbiographie: Bell Laboratories traces its lineage back to Alexander Graham Bell, who used prize money from the 1880 French Volta Prize for the invention of the telephone to create the Volta Laboratory in Washington, DC. (In collaboration with Sumner Tainter and Chichester Bell.) He continued his research into ways of analyzing, recording, and transmitting sound.

In 1875 an informal trust and partnership was created to manage the patents developed by Bell and Thomas Watson, with the initial partners being Bell, Gardiner Greene Hubbard (Bell's father-in-law), and Thomas Sanders (father of one of Bell's deaf students).

in 1877, Hubbard set up the Bell Telephone Company in Boston, Massachusetts, to formalize the partnership as a joint-stock company, with Thomas Watson as its first full-time employee.

In 1878, Bell Telephone was incorporated in Massachusetts, and merged with the New England Telephone and Telegraph Company (also founded by Hubbard) to form the National Bell Telephone Company, then reorganized as the American Bell Telephone Company. Amongst other subsidiaries, including the American Telephone and Telegraph company (AT&T) (managing long-distance telecommunication) and a controlling share of Western Electric, which manufactured telephone equipment. In 1899, more corporate changes led to AT&T being given control over American Bell and the "Bell System" as a whole.

In 1925, AT&T and Western Electric formed Bell Telephone Laboratories to bring all the research and engineering work together. Its offices were originally in New York City, but in 1967, Bell Labs's headquarters moved to Murray Hill, New Jersey, joining other divisions that had previously moved to New Jersey.

Bell Labs's scientists have both invented and refined many concepts and technologies, including the transistor, and contributed fundamental approaches to mathematics, physics, and computing, including the UNIX operating system and the C programming language.

Rezensionen

Engineering and operations in the Bell System von Bell Telephone Laboratories.

Although over thirty-five years out of date, this book provides "a broad picture of engineering and operations in the Bell System." The material was prepared for a course given within Bell Laboratories "primarily for those with little background in the telephone business." It is an extraordinarily comprehensive discussion of an enormously complicated and ever changing network, exploring numerous facets including business economics, customer satisfaction, monitoring and maintenance, theoretical design, implementation, manufacturng, and staffing.

Of particular interest is the fact that the system described is undergoing the transition from the old electromechanical system to a moden system of electronic switching and the use of computers for monitoring quality and managing data (one foot on the dock and one foot on the boat, as it were). Many of the diagnostic programs in use are broadly outlined. It is unfortunate that there is no mention of UNIX, which had been under development in Bell Laborties since 1969 and which would revolutionize computer systems beginning just after this book was published.… (mehr)
