# Nokia Bell Labs

Nokia Bell Labs, formerly Bell Telephone Laboratories, is an American industrial research and development company owned by Nokia, headquartered in Murray Hill, New Jersey, and credited with foundational innovations such as the transistor, laser, Unix, and information theory.

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. 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.

## Early antecedents and the Volta Laboratory

In 1880, 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 roughly $350,000 in modern terms. Bell 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 focused on the analysis, recording, and transmission of sound. Bell used profits from the laboratory for further research and education, particularly advancing knowledge relating to the deaf, which led to the founding of the Volta Bureau around 1887. In 1893, Bell constructed a new building at 1537 35th Street N.W. to house the lab, which was declared a National Historic Landmark in 1972.

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. The Bell Telephone Company, the first telephone company, was formed a year later and later became 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 subsidiary took control of American Bell and the Bell System by 1899. American Bell held a controlling interest in Western Electric, the manufacturing arm, while AT&T conducted research into service providers.

## Formal organization and early locations

In 1896, Western Electric bought property at 463 West Street in New York City to centralize the manufacturers and engineers supplying AT&T with 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, and 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, and a transmission studies site was built in Phoenixville, Pennsylvania, which in 1929 constructed 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 development and research activities for the Bell System. Ownership was evenly shared between Western Electric and AT&T. The new company had 3,600 engineers, scientists, and support staff, and its 400,000-square-foot space was expanded with a new building occupying about one quarter of a city block. The first chairman of the board was John J. Carty, AT&T's vice president, and the first president was Frank B. Jewett, who stayed until 1940. Operations were directed by E. B. Craft, executive vice-president and formerly chief engineer at Western Electric.

In the early 1920s, outdoor facilities and radio communications development sites were established. In 1925, test plot studies were set up in Gulfport, Mississippi, for wood preservation of telephone poles. At Deal, New Jersey, work was done on ship-to-shore radio telephony. In 1926, land was acquired in the Whippany section of Hanover Township, New Jersey, for a 50-kilowatt broadcast transmitter, and in 1931, 75 acres were added. In 1928, a 15-acre site in Chester Township, New Jersey, was leased for outdoor tests, and in 1930, an additional 85 acres were purchased for a new outdoor plant development laboratory. A test plot was also installed in Limon, Colorado, in 1929, similar to the one in Gulfport.

## Major scientific contributions

Throughout the 20th century, Bell Labs researchers produced a remarkable array of innovations. The transistor, invented in 1947 by John Bardeen, Walter Brattain, and William Shockley, revolutionized electronics and earned the team the Nobel Prize in Physics in 1956. The laser was first demonstrated by Arthur Leonard Schawlow and Charles Hard Townes, building on earlier maser work, and Bell Labs later developed practical applications in communications. The photovoltaic cell, capable of converting light into electricity, was advanced significantly at the lab. The charge-coupled device (CCD), invented by Willard Boyle and George E. Smith in 1969, became the basis for digital imaging and earned them the Nobel Prize in Physics in 2009.

Information theory, founded by Claude Shannon in his seminal 1948 paper "A Mathematical Theory of Communication," established the quantitative limits of data transmission and compression. 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, C++, S, SNOBOL, AWK, and AMPL were all created at Bell Labs, with C and C++ becoming among the most widely used languages in software development. Radio astronomy was also pioneered at Bell Labs, notably with the discovery of cosmic microwave background radiation by Arno Penzias and Robert Woodrow Wilson in 1965, which earned them the Nobel Prize in Physics in 1978.

## Corporate changes and the AT&T breakup

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 lost its guaranteed funding from the telephone monopoly. Despite the reduced budget, the lab continued to produce important research, including advances in fiber optics, wireless communications, and software.

In 1996, AT&T spun off AT&T Technologies, which was renamed Lucent Technologies, using the Murray Hill site for headquarters. Bell Laboratories was split, with AT&T retaining parts as AT&T Laboratories. Lucent continued to operate Bell Labs as its research arm, focusing on telecommunications equipment and software. In 2006, Lucent merged with French telecommunication company Alcatel to form Alcatel-Lucent, and Bell Labs became part of that combined entity. Alcatel-Lucent was acquired by Nokia in 2016, and the research organization was renamed Nokia Bell Labs.
