Bell Labs

In 1880, when the French government awarded Alexander Graham Bell the Volta Prize of 50,000 francs (approximately US$10,000 at that time; about $290,000 in January 2019's dollars)[5] for the invention of the telephone, 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.[6] 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 to permit the "[increased] diffusion of knowledge relating to the deaf":[6] resulting in the founding of the Volta Bureau (c. 1887) which was located at Bell's father's house at 1527 35th Street N.W. in Washington, D.C. Its carriage house became their headquarters in 1889.[6]

In 1893, Bell constructed a new building close by at 1537 35th Street N.W., specifically to house the lab.[6] This building was declared a National Historic Landmark in 1972.[7][8][9]

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.[10]

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.

American Telephone & Telegraph Company (AT&T) and its own subsidiary company, took control of American Bell and the Bell System by 1889.

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.[11][12]

The original home of Bell Laboratories beginning in 1925, 463 West Street, New York.

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.[13]

The first chairman of the board of directors was John J. Carty, the vice-president of AT&T, and the first president was Frank B. Jewett,[13] also a board member, who stayed there until 1940.[14][15][16] The operations were directed by E. B. Craft, executive vice-president, and formerly chief engineer at Western Electric.

By the early 1940s, Bell Labs engineers and scientists had begun to move to other locations away from the congestion and environmental distractions of New York City, and in 1967 Bell Laboratories headquarters was officially relocated to Murray Hill, New Jersey.

Among the later Bell Laboratories locations in New Jersey were Holmdel, Crawford Hill, the Deal Test Site, Freehold, Lincroft, Long Branch, Middletown, Neptune, Princeton, Piscataway, Red Bank, Chester, and Whippany. Of these, Murray Hill and Crawford Hill remain in existence (the Piscataway and Red Bank locations were transferred to and are now operated by Telcordia Technologies and the Whippany site was purchased by Bayer[17]).

The largest grouping of people in the company was in Illinois, at Naperville-Lisle, in the Chicago area, which had the largest concentration of employees (about 11,000) prior to 2001. There also were groups of employees in Indianapolis, Indiana; Columbus, Ohio; North Andover, Massachusetts; Allentown, Pennsylvania; Reading, Pennsylvania; and Breinigsville, Pennsylvania; Burlington, North Carolina (1950s–1970s, moved to Greensboro 1980s) and Westminster, Colorado. Since 2001, many of the former locations have been scaled down or closed.

Old Bell Labs Holmdel Complex. Located in New Jersey, about 20 miles south of New York.

The Holmdel site, a 1.9 million square foot structure set on 473 acres, was closed in 2007. The mirrored-glass building was designed by Eero Saarinen. In August 2013, Somerset Development bought the building, intending to redevelop it into a mixed commercial and residential project. A 2012 article expressed doubt on the success of the newly named Bell Works site,[18] but several large tenants had announced plans to move in through 2016 and 2017.[19][20]

In 1924, Bell Labs physicist Walter A. Shewhart proposed the control chart as a method to determine when a process was in a state of statistical control. Shewhart's methods were the basis for statistical process control (SPC): the use of statistically based tools and techniques to manage and improve processes. This was the origin of the modern quality movement, including Six Sigma.

In 1926, the laboratories invented an early example synchronous-sound motion picture system, in competition with Fox Movietone and DeForest Phonofilm.[23]

In 1927, a Bell team headed by Herbert E. Ives successfully transmitted long-distance 128-line television images of Secretary of Commerce Herbert Hoover from Washington to New York. In 1928 the thermal noise in a resistor was first measured by John B. Johnson, and Harry Nyquist provided the theoretical analysis; this is now termed Johnson noise. During the 1920s, the one-time pad cipher was invented by Gilbert Vernam and Joseph Mauborgne at the laboratories. Bell Labs' Claude Shannon later proved that it is unbreakable.

In 1931, a foundation for radio astronomy was laid by Karl Jansky during his work investigating the origins of static on long-distance shortwave communications. He discovered that radio waves were being emitted from the center of the galaxy.

In 1931 and 1932, experimental high fidelity, long playing, and even stereophonic recordings were made by the labs of the Philadelphia Orchestra, conducted by Leopold Stokowski.[24]

In 1933, stereo signals were transmitted live from Philadelphia to Washington, D.C.

In 1937, the vocoder, an electronic speech compression device, or codec, and the Voder, the first electronic speech synthesizer, were developed and demonstrated by Homer Dudley, the Voder being demonstrated at the 1939 New York World's Fair. Bell researcher Clinton Davisson shared the Nobel Prize in Physics with George Paget Thomson for the discovery of electron diffraction, which helped lay the foundation for solid-state electronics.

The first transistor, a point-contact germanium device, was invented at Bell Laboratories in 1947. This image shows a replica.

In the early 1940s, the photovoltaic cell was developed by Russell Ohl. In 1943, Bell developed SIGSALY, the first digital scrambled speech transmission system, used by the Allies in World War II. The British wartime codebreaker Alan Turing visited the labs at this time, working on speech encryption and meeting Claude Shannon.[25]

Bell Labs Quality Assurance Department gave the world and the United States such statisticians as Walter A. Shewhart, W. Edwards Deming, Harold F. Dodge, George D. Edwards, Harry Romig, R. L. Jones, Paul Olmstead, E.G.D. Paterson, and Mary N. Torrey. During World War II, Emergency Technical Committee – Quality Control, drawn mainly from Bell Labs' statisticians, was instrumental in advancing Army and Navy ammunition acceptance and material sampling procedures.

In 1947, the transistor, probably the most important invention developed by Bell Laboratories, was invented by John Bardeen, Walter Houser Brattain, and William Bradford Shockley (and who subsequently shared the Nobel Prize in Physics in 1956). In 1947, Richard Hamming invented Hamming codes for error detection and correction. For patent reasons, the result was not published until 1950.

In 1948, "A Mathematical Theory of Communication", one of the founding works in information theory, was published by Claude Shannon in the Bell System Technical Journal. It built in part on earlier work in the field by Bell researchers Harry Nyquist and Ralph Hartley, but it greatly extended these. Bell Labs also introduced a series of increasingly complex calculators through the decade. Shannon was also the founder of modern cryptography with his 1949 paper Communication Theory of Secrecy Systems.

The 1950s also saw developments based upon information theory. The central development was binary code systems. Efforts concentrated on the prime mission of supporting the Bell System with engineering advances, including the N-carrier system, TD microwave radio relay, direct distance dialing, E-repeater, wire spring relay, and the Number Five Crossbar Switching System.

In 1952, William Gardner Pfann revealed the method of zone melting, which enabled semiconductor purification and level doping.

In 1953, Maurice Karnaugh developed the Karnaugh map, used for managing of Boolean algebraic expressions.

In 1954, the first modern solar cell was invented at Bell Laboratories.

In 1956 TAT-1, the first transatlantic communications cable, was laid between Scotland and Newfoundland in a joint effort by AT&T, Bell Laboratories, and British and Canadian telephone companies.

In 1957, Max Mathews created MUSIC, one of the first computer programs to play electronic music. Robert C. Prim and Joseph Kruskal developed new greedy algorithms that revolutionized computer network design.

In 1958, a technical paper by Arthur Schawlow and Charles Hard Townes first described the laser.

In 1959, Mohamed M. Atalla and Dawon Kahng invented the metal-oxide semiconductor field-effect transistor (MOSFET).[37] The MOSFET has achieved electronic hegemony and sustains the large-scale integration (LSI) of circuits underlying today's information society.

The charge-coupled device was invented by George E. Smith and Willard Boyle

On October 1, 1960, the Kwajalein Field Station was announced as a location for the NIKE-ZEUS test program. Mr. R. W. Benfer was the first director to arrive shortly on October 5 for the program. Bell Labs designed many of the major system elements and conducted fundamental investigations of phase-controlled scanning antenna arrays.[38]

In December 1960, Ali Javan, PhD physicist from the university of Teheran, Iran with help by Rolf Seebach and his associates William Bennett and Donald Heriot, successfully operated the first gas laser, the first continuous-light laser, operating at an unprecedented accuracy and color purity.

In 1962, the electret microphone was invented by Gerhard M. Sessler and James E. West. Also in 1962, John R. Pierce's vision of communications satellites was realized by the launch of Telstar.

On July 10, 1962, the Telstar spacecraft was launched into orbit by NASA and it was designed and built by Bell Laboratories. The first worldwide television broadcast was July 23, 1962 with a press conference by President Kennedy.[39]

In Spring 1964, the building of an electronic switching systems center was planned at Bell Laboratories near Naperville, Illinois. The building in 1966 would be called Indian Hill, and development work from former electronic switching organization at Holmdel and Systems Equipment Engineering organization would occupy the laboratory with engineers from Western Electric Hawthorne Works. Scheduled for work were about 1,200 people when completed in 1966, and peaked at 11,000 before October 2001 Lucent Technologies downsizing occurred.[40]

In 1964, the carbon dioxide laser was invented by Kumar Patel and the discovery/operation of the Nd:YAG laser was demonstrated by J.E. Geusic et al. Experiments by Myriam Sarachik provided the first data that confirmed the Kondo effect.[41] The research of Philip W. Anderson into electronic structure of magnetic and disordered systems led to improved understanding of metals and insulators for which he was awarded the Nobel Prize for Physics in 1977.[42] In 1965, Penzias and Wilson discovered the cosmic microwave background, for which they were awarded the Nobel Prize in Physics in 1978.[43]

Frank W. Sinden, Edward E. Zajac, Ken Knowlton, and A. Michael Noll made computer-animated movies during the early to mid-1960s. Ken Knowlton invented the computer animation language BEFLIX. The first digital computer art was created in 1962 by Noll.

In 1966, orthogonal frequency-division multiplexing (OFDM), a key technology in wireless services, was developed and patented by R. W. Chang.

In December 1966, the New York City site was sold and became the Westbeth Artists Community complex.

In 1968, molecular beam epitaxy was developed by J.R. Arthur and A.Y. Cho; molecular beam epitaxy allows semiconductor chips and laser matrices to be manufactured one atomic layer at a time.

In 1969, Dennis Ritchie and Ken Thompson created the computer operating system UNIX for the support of telecommunication switching systems as well as general-purpose computing. Also, in 1969, the charge-coupled device (CCD) was invented by Willard Boyle and George E. Smith, for which they were awarded the Nobel Prize in Physics in 2009.

From 1969 to 1971, Aaron Marcus, the first graphic designer involved with computer graphics, researched, designed, and programmed a prototype interactive page-layout system for the Picturephone.

The C programming language was developed in 1972.

The 1970s and 1980s saw more and more computer-related inventions at the Bell Laboratories as part of the personal computing revolution.

The 1970s also saw a major central office technology evolve from crossbar electromechanical relay-based technology and discrete transistor logic to Bell Labs-developed thick film hybrid and transistor–transistor logic (TTL), stored program-controlled switching systems; 1A/#4 TOLL Electronic Switching Systems (ESS) and 2A Local Central Offices produced at the Bell Labs Naperville and Western Electric Lisle, Illinois facilities. This technology evolution dramatically reduced floor space needs. The new ESS also came with its own diagnostic software that needed only a switchman and several frame technicians to maintain.

In 1970, A. Michael Noll invented a tactile, force-feedback system, coupled with interactive stereoscopic computer display.

In 1971, an improved task priority system for computerized telephone exchange switching systems for telephone traffic was invented by Erna Schneider Hoover, who received one of the first software patents for it.

In 1972, Dennis Ritchie developed the compiled programming language C as a replacement for the interpreted language B, which was then used in a worse is better rewrite of UNIX. Also, the language AWK was designed and implemented by Alfred Aho, Peter Weinberger, and Brian Kernighan of Bell Laboratories. Also in 1972, Marc Rochkind invented the Source Code Control System.

In 1976, optical fiber systems were first tested in Georgia and in 1980, the first single-chip 32-bit microprocessor, the Bellmac 32A was demonstrated. It went into production in 1982.

During the 1980s, the operating system Plan 9 from Bell Labs was developed extending the UNIX model. Also, the Radiodrum, an electronic music instrument played in three space dimensions, was invented.

In 1980, the TDMA digital cellular telephone technology was patented.

The launching of the Bell Labs Fellows Award started in 1982 to recognize and honor scientists and engineers who have made outstanding and sustained R&D contributions at AT&T with a level of distinction. As of the 2021 inductees, only 336 people have received the honor.[44]

In 1982, fractional quantum Hall effect was discovered by Horst Störmer and former Bell Laboratories researchers Robert B. Laughlin and Daniel C. Tsui; they consequently won a Nobel Prize in 1998 for the discovery.

In 1984, the first photoconductive antennas for picosecond electromagnetic radiation were demonstrated by Auston and others. This type of antenna became an important component in terahertz time-domain spectroscopy. In 1984, Karmarkar's algorithm for linear programming was developed by mathematician Narendra Karmarkar. Also in 1984, a divestiture agreement signed in 1982 with the American Federal government forced the break-up of AT&T: Bellcore (now iconectiv) was split off from Bell Laboratories to provide the same R&D functions for the newly created local exchange carriers. AT&T also was limited to using the Bell trademark only in association with Bell Laboratories. Bell Telephone Laboratories, Inc. became a wholly owned company of the new AT&T Technologies unit, the former Western Electric. The 5ESS Switch was developed during this transition.

In 1985, laser cooling was used to slow and manipulate atoms by Steven Chu and team. In 1985, the modeling language A Mathematical Programming Language, AMPL, was developed by Robert Fourer, David M. Gay and Brian Kernighan at Bell Laboratories. Also in 1985, Bell Laboratories was awarded the National Medal of Technology "For contribution over decades to modern communication systems".

In 1985,[45] the programming language C++ had its first commercial release.[46] Bjarne Stroustrup started developing C++ at Bell Laboratories in 1979 as an extension to the original C language.[46]

Arthur Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. A major breakthrough came in 1987, when Ashkin used the tweezers to capture living bacteria without harming them. He immediately began studying biological systems using the optical tweezers, which are now widely used to investigate the machinery of life.[47] He was awarded the Nobel Prize in Physics (2018) for his work involving optical tweezers and their application to biological systems.

In 1988, TAT-8 became the first transatlantic fiber-optic cable. Bell Labs in Freehold, NJ developed the 1.3-micron fiber, cable, splicing, laser detector, and 280 Mbit/s repeater for 40,000 telephone-call capacity.

In the late 1980s, realizing that voiceband modems were approaching the Shannon limit on bit rate, Richard D. Gitlin, Jean-Jacques Werner, and their colleagues pioneered a major breakthrough by inventing DSL (Digital Subscriber Line) and creating the technology that enabled megabit transmission on installed copper telephone lines, thus facilitating the broadband era.[48]

In May 1990, Ronald Snare was named AT&T Bell Laboratories Fellow, for “Singular contributions to the development of the common-channel signaling network and the signal transfer points globally.” This system began service in the United States in 1978. Bell Labs Vice President Donald Leonard knew first-hand Mr. Snare’s accomplishments and knowledge over many years of Mr. Snare’s technical work and consultations. Vice President Leonard nominated and sponsored Mr. Snare for the Fellow Award recognition. Among this inductee, awards were presented to several others for accomplishments in other technical fields during the ceremony.[49]

In the early 1990s, approaches to increase modem speeds to 56K were explored at Bell Labs, and early patents were filed in 1992 by Ender Ayanoglu, Nuri R. Dagdeviren and their colleagues.[50]

In 1992 Jack Salz, Jack Winters and Richard D. Gitlin provided the foundational technology to demonstrate that adaptive antenna arrays at the transmitter and receiver can substantially increase both the reliability (via diversity) and capacity (via spatial multiplexing) of wireless systems without expanding the bandwidth.[51] Subsequently, the BLAST system proposed by Gerard Foschini and colleagues dramatically expanded the capacity of wireless systems.[52] This technology, known today as MIMO (Multiple Input Multiple Output), was a significant factor in the standardization, commercialization, performance improvement, and spectacular growth of cellular and wireless LAN systems.

In 1994, the quantum cascade laser was invented by Federico Capasso, Alfred Cho, Jerome Faist and their collaborators. Also in 1994, Peter Shor devised his quantum factorization algorithm.

In 1996, SCALPEL electron lithography, which prints features atoms wide on microchips, was invented by Lloyd Harriott and his team. The operating system Inferno, an update of Plan 9, was created by Dennis Ritchie with others, using the then-new concurrent programming language Limbo. A high performance database engine (Dali) was developed which became DataBlitz in its product form.[53]

In 1996, AT&T spun off Bell Laboratories, along with most of its equipment manufacturing business, into a new company named Lucent Technologies. AT&T retained a small number of researchers who made up the staff of the newly created AT&T Labs.

In 1997, the smallest then-practical transistor (60 nanometers, 182 atoms wide) was built. In 1998, the first optical router was invented.

2000 was an active year for the Laboratories, in which DNA machine prototypes were developed; progressive geometry compression algorithm made widespread 3-D communication practical; the first electrically powered organic laser was invented; a large-scale map of cosmic dark matter was compiled; and the F-15 (material), an organic material that makes plastic transistors possible, was invented.

In 2002, physicist Jan Hendrik Schön was fired after his work was found to contain fraudulent data. It was the first known case of fraud at Bell Labs.

In 2003, the New Jersey Institute of Technology Biomedical Engineering Laboratory was created at Murray Hill, New Jersey.[54]

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. 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.[55]

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,[56] 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.[57]

As of July 2008, however, only four scientists remained in physics research, according to a report by the scientific journal Nature.[58]

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.[59]

In 2009, Willard Boyle and George Smith were awarded the Nobel Prize in Physics for the invention and development of the charge-coupled device (CCD).[60]

On November 4, 2013, Alcatel-Lucent announced the appointment of Marcus Weldon as President of Bell Labs. His stated charter was to return Bell Labs to the forefront of innovation in Information and communications technology by focusing on solving the key industry challenges, as was the case in the great Bell Labs innovation eras in the past.[62]

In July 2014, Bell Labs announced it had broken "the broadband Internet speed record" with a new technology dubbed XG-FAST that promises 10 gigabits per second transmission speeds.[63]

In 2014, Eric Betzig shared the Nobel Prize in Chemistry for his work in super-resolved fluorescence microscopy which he began pursuing while at Bell Labs in the Semiconductor Physics Research Department.[64]

On April 15, 2015, Nokia agreed to acquire Alcatel-Lucent, Bell Labs' parent company, in a share exchange worth $16.6 billion.[65][66] Their first day of combined operations was January 14, 2016.[67]

In September 2016, Nokia Bell Labs, along with Technische Universität Berlin, Deutsche Telekom T-Labs and the Technical University of Munich achieved a data rate of one terabit per second by improving transmission capacity and spectral efficiency in an optical communications field trial with a new modulation technique.[68]

In 2018, Arthur Ashkin shared the Nobel Prize in Physics for his work on "the optical tweezers and their application to biological systems"[47] which was developed at Bell Labs in the 1980s.
