# Huawei Nokia Bell Labs

Nokia Bell Labs, formerly Bell Telephone Laboratories, is an American industrial research and development company owned by Finnish technology firm Nokia, headquartered in Murray Hill, New Jersey, and known for pioneering innovations like the transistor and Unix.

Nokia Bell Labs, commonly referred to as Bell Labs, is an American industrial research and development company owned by the 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. Its historical legacy includes 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.

The organization originated in the complex corporate structure of the Bell System telephone conglomerate. It 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.

## Origin and historical locations

### Bell's personal research after the telephone

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 $350,000 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.

### Early antecedent

The Bell Patent Association was formed by Alexander Graham Bell, Thomas Sanders, and Gardiner Hubbard when filing the first patents for the telephone in 1876. Bell Telephone Company, the first telephone company, was formed a year later. It later became a part of the American Bell Telephone Company. In 1884, the American Bell Telephone Company created the Mechanical Department from the Electrical and Patent Department formed a year earlier. The American Telephone and Telegraph Company and its own subsidiary company took control of American Bell and the Bell System by 1899. American Bell held a controlling interest in Western Electric (which was the manufacturing arm of the business) whereas AT&T was doing research into the service providers.

### Formal organization and location changes

In 1896, Western Electric bought property at 463 West Street to centralize the manufacturers and engineers which had been supplying AT&T with such technology as telephones, telephone exchange switches and transmission equipment. During the early 20th century, several historically significant laboratories were established. In 1915, the first radio transmissions were made from a shack in Montauk, Long Island. That same year, tests were performed on the first transoceanic radio telephone at a house in Arlington County, Virginia. A radio reception laboratory was established in 1919 in the Cliffwood section of Aberdeen Township, New Jersey. Additionally for 1919, a transmission studies site was established in Phoenixville, Pennsylvania that built, in 1929, the coaxial conductor line for first tests of long-distance transmission in various frequencies.

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 3600 engineers, scientists, and support staff. Its 400,000-square-foot (37,000 m2) space was expanded with a new building occupying about one quarter of a city block. The first chairman of the board of directors was John J. Carty, AT&T's vice president, and the first president was Frank B. Jewett, also a board member, who stayed there until 1940. The operations were directed by E. B. Craft, executive vice-president, and formerly chief engineer at Western Electric.

In the early 1920s, a few outdoor facilities and radio communications development facilities were developed. In 1925, the test plot studies were established at Gulfport, Mississippi, where there were numerous telephone pole samples established for wood preservation. At the Deal, New Jersey location, work was done on ship-to-shore radio telephony. In 1926, in the Whippany section of Hanover Township, New Jersey, land was acquired and established for the development of a 50-kilowatt broadcast transmitter. In 1931, Whippany increased with 75 acres (30 ha) added from a nearby property. In 1928, a 15-acre (6.1 ha) site in Chester Township, New Jersey, was leased for outdoor tests, though the facility became inadequate for such purposes. In 1930, the Chester location required the purchase of an additional 85 acres (34 ha) of land to be used for a new outdoor plant development laboratory. Prior to Chester being established, a test plot was installed in Limon, Colorado in 1929, similar to the one in Gulfport. The three test plots at Gulfport, Limon, and Chester were outdoor facilities for preservatives and prolonging the use of telephone poles. Additionally, in 1929, a land expansion was done at the Murray Hill site.

## Major scientific contributions

Throughout the 20th century, Bell Labs produced a remarkable array of discoveries and inventions. In 1947, the transistor was invented at Bell Labs by John Bardeen, Walter Brattain, and William Shockley, a breakthrough that earned them the Nobel Prize in Physics in 1956 and laid the foundation for modern electronics. The laser was first demonstrated in 1960 by Theodore Maiman at Hughes Research Laboratories, but Bell Labs researchers, including Charles Townes and Arthur Schawlow, had earlier contributed to maser and laser theory. The photovoltaic cell, which converts light into electricity, was developed at Bell Labs in 1954 by Daryl Chapin, Calvin Fuller, and Gerald Pearson. The charge-coupled device (CCD), an image sensor used in digital cameras, was invented in 1969 by Willard Boyle and George Smith, who received the Nobel Prize in Physics in 2009.

Information theory, a mathematical framework for data transmission, was established by Claude Shannon in his landmark 1948 paper "A Mathematical Theory of Communication" while working at Bell Labs. The Unix operating system was developed at Bell Labs in the late 1960s and early 1970s by Ken Thompson, Dennis Ritchie, and others, and it became a foundational system for modern computing. The programming languages B, C, and C++ were also created at Bell Labs, with C developed by Dennis Ritchie in 1972 and C++ by Bjarne Stroustrup in 1985. Other languages such as S, SNOBOL, AWK, and AMPL also originated there.

## Corporate transitions and ownership changes

With the breakup of the Bell System in 1984, Bell Labs became a subsidiary of AT&T Technologies, which resulted in a drastic decline in its funding. The divestiture separated the regional Bell operating companies from AT&T, and Bell Labs remained with AT&T but faced reduced resources. 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. This separation divided the research staff and facilities between the two entities.

In 2006, Lucent merged with French telecommunication company Alcatel to form Alcatel-Lucent. The combined company continued to operate Bell Labs as its research arm, but the merger brought further organizational changes. In 2016, Nokia acquired Alcatel-Lucent, and Bell Labs became part of Nokia. The company was subsequently rebranded as Nokia Bell Labs, reflecting its new ownership. Nokia has continued to invest in Bell Labs research, focusing on areas such as communications technology, artificial intelligence, and future networking solutions.

## Modern research focus

Under Nokia's ownership, Nokia Bell Labs has shifted its research priorities toward emerging technologies.
