Bell Labs

Nokia Bell Labs, commonly referred to as Bell Labs, is an American industrial research and development company owned by Finnish technology company Nokia. With headquarters located in Murray Hill, New Jersey, the company operates several laboratories in the United States and around the world.

As a former subsidiary of the American Telephone and Telegraph Company (AT&T), Bell Labs and its researchers have been credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages B, C, C++, S, SNOBOL, AWK, AMPL, and others, throughout the 20th century. Eleven Nobel Prizes and five Turing Awards have been awarded for work completed at Bell Laboratories.

Bell Labs had its origin in the complex corporate organization of the Bell System telephone conglomerate. The laboratory began operating in the late 19th century as the Western Electric Engineering Department, located at 463 West Street in New York City. After years of advancing telecommunication innovations, the department was reformed into Bell Telephone Laboratories in 1925 and placed under the shared ownership of Western Electric and the American Telephone and Telegraph Company. In the 1960s, laboratory and company headquarters were moved to Murray Hill, New Jersey. Its alumni during this time include a plethora of world-renowned scientists and engineers.

With the breakup of the Bell System, Bell Labs became a subsidiary of AT&T Technologies in 1984, which resulted in a drastic decline in its funding. In 1996, AT&T spun off AT&T Technologies, which was renamed to Lucent Technologies, using the Murray Hill site for headquarters. Bell Laboratories was split with AT&T retaining parts as AT&T Laboratories. In 2006, Lucent merged with French telecommunication company Alcatel to form Alcatel-Lucent, which was acquired by Nokia in 2016.

In 1880, when the French government awarded Alexander Graham Bell the Volta Prize of 50,000 francs for the invention of the telephone (equivalent to about US$10,000 at the time, or about $340,000 now), he used the award to fund the Volta Laboratory (also known as the "Alexander Graham Bell Laboratory") in Washington, D.C. in collaboration with Sumner Tainter and Bell's cousin Chichester Bell. The laboratory was variously known as the Volta Bureau, the Bell Carriage House, the Bell Laboratory and the Volta Laboratory.

It focused on the analysis, recording, and transmission of sound. Bell used his considerable profits from the laboratory for further research and education advancing the diffusion of knowledge relating to the deaf. This resulted in the founding of the Volta Bureau (c. 1887) at the Washington, D.C. home of his father, linguist Alexander Melville Bell. The carriage house there, at 1527 35th Street N.W., became their headquarters in 1889.

In 1893, Bell constructed a new building close by at 1537 35th Street N.W., specifically to house the lab. This building was declared a National Historic Landmark in 1972.

After the invention of the telephone, Bell maintained a relatively distant role with the Bell System as a whole, but continued to pursue his own personal research interests.
