Bell Labs had its origin in the complex corporate organization of the

463 West Street in New York City. In 1925, after years of conducting research and development under
Western Electric, a Bell subsidiary, the Engineering Department was reformed into Bell Telephone Laboratories and placed under the shared ownership of the

Alexander Graham Bell, Thomas Sanders, and

Formal organization and location changes
![Bell Laboratories West Street](https://upload.wikimedia.org/wikipedia/commons/4/4c/Bell_Laboratories_West_Street.jpg)
In 1896, Western Electric bought property at
463 West Street to station their manufacturers and engineers who had been supplying AT&T with their product. This included everything from telephones,
telephone exchange switches, and transmission equipment.
On January 1, 1925, Bell Telephone Laboratories, Inc. was organized to consolidate the development and research activities in the communication field and allied sciences for the Bell System. Ownership was evenly shared between
Western Electric and AT&T. The new company had existing personnel of 3600 engineers, scientists, and support staff. In addition to the existing research facilities of 400,000 square feet of space, its space was extended with a new building on about one quarter of a city block.

In 2004, Lucent Technologies awarded two women the prestigious Bell Labs Fellow Award. Magaly Spector, a director in INS/Network Systems Group, was awarded for "sustained and exceptional scientific and technological contributions in solid-state physics, III-V material for semiconductor lasers, Gallium Arsenide integrated circuits, and the quality and reliability of products used in high speed optical transport systems for next generation high bandwidth communication." Eve Varma, a technical manager in MNS/Network Systems Group, was awarded for her citation in "sustained contributions to digital and optical networking, including architecture, synchronization, restoration, standards, operations and control."
In 2005, Jeong H. Kim, former President of Lucent's Optical Network Group, returned from academia to become the President of Bell Laboratories.
In April 2006, Bell Laboratories' parent company, Lucent Technologies, signed a merger agreement with Alcatel-Lucent, Alcatel. On December 1, 2006, the merged company, Alcatel-Lucent, began operations. This deal raised concerns in the United States, where Bell Laboratories works on defense contracts. A separate company, LGS Innovations, with an American board was set up to manage Bell Laboratories' and Lucent's sensitive U.S. government contracts. In March 2019, LGS Innovations was purchased by CACI.
In December 2007, it was announced that the former Lucent Bell Laboratories and the former Alcatel Research and Innovation would be merged into one organization under the name of Bell Laboratories. This is the first period of growth following many years during which Bell Laboratories progressively lost manpower due to layoffs and spin-offs making the company shut down briefly.
In February 2008, Alcatel-Lucent continued the Bell Laboratories tradition of awarding the prestigious award for outstanding technical contributors. Martin J. Glapa, a former chief Technical Officer of Lucent's Cable Communications Business Unit and Director of Advanced Technologies, was presented by Alcatel-Lucent Bell Labs President Jeong H. Kim with the 2006 Bell Labs Fellow Award in Network Architecture, Network Planning, and Professional Services with particular focus in Cable TV Systems and Broadband Services having "significant resulting Alcatel-Lucent commercial successes." Glapa is a patent holder and has co-written the 2004 technical paper called "Optimal Availability & Security For Voice Over Cable Networks" and co-authored the 2008 "Impact of bandwidth demand growth on HFC networks" published by IEEE.
As of July 2008, however, only four scientists remained in physics research, according to a report by the scientific journal ''Nature''.
On August 28, 2008, Alcatel-Lucent announced it was pulling out of basic science, material physics, and semiconductor research, and it will instead focus on more immediately marketable areas, including networking, high-speed electronics, wireless networks, nanotechnology and software.
In 2009, Willard Boyle and George Smith were awarded the Nobel Prize in Physics for the invention and development of the

Publications
The American Telephone and Telegraph Company, Western Electric, and other Bell System companies issued numerous publications, such as local house organs, for corporate distribution, for the scientific and industry communities, and for the general public, including telephone subscribers.
The Bell Laboratories Record was a principal house organ, featuring general interest content such as corporate news, support staff profiles and events, reports of facilities upgrades, but also articles of research and development results written for technical or non-technical audiences. The publication commenced in 1925 with the founding of the laboratories.
A prominent journal for the focussed dissemination of original or reprinted scientific research by Bell Labs engineers and scientists was the ''
Bell System Technical Journal'', started in 1922 by the AT&T Information Department. Bell researchers also published widely in industry journals.
Some of these articles were reprinted by the Bell System as Monographs, consecutively issued starting in 1920. These reprints, numbering over 5000, comprise a catalog of Bell research over the decades. Research in the Monographs is aided by access to associated indexes, for monographs 1–1199, 1200-2850 (1958), 2851-4050 (1962), and 4051-4650 (1964).
Essentially all of the landmark work done by Bell Labs is memorialized in one or more corresponding monographs. Examples include:
* Monograph 1598 - Shannon, A Mathematical Theory of Communication, 1948 (reprinted from BSTJ).
* Monograph 1659 - Bardeen and Brattain, Physical Principles Involved in Transistor Action, 1949 (reprinted from BSTJ).
* Monograph 1757 - Hamming, Error Detecting and Error Correcting Codes, 1950 (reprinted from BSTJ).
* Monograph 3289 - Pierce, Transoceanic Communications by Means of Satellite, 1959 (reprinted from Proc. I.R.E.).
