Bell Labs

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 Deal Labs to 208 acres (84 ha). This added land increased the facility for radio transmission studies.

The buyer, Franklin Partners, purchased the 41-acre (17 ha) site for warehousing but decisions were made to demolish the building for future approved planning. The pedestrian bridge to Indian Hill building was demolished as a separated company. The conference room and lobby scenes of the building were filmed in July 2010, during Alcatel-Lucent ownership, for the Ron Howard film, The Dilemma.)

Discoveries and developments

Bell Laboratories is known by many for developing a wide range of technologies, including radio astronomy, the transistor, the laser, information theory, the operating system Unix, the programming languages C and C++, solar cells, the charge-coupled device (CCD), and many other optical, wireless, and wired communications technologies and systems.

1920s

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 control movement, including Six Sigma.

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

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, for which Harry Nyquist provided the theoretical analysis; this is now termed Johnson-Nyquist 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 1928, Harold Black invented the negative feedback system commonly used in amplifiers. Later, Harry Nyquist analyzed Black's design rule for negative feedback. This work was published in 1932 and became known as the Nyquist criterion.

1930s

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, the labs made experimental high fidelity, long playing, and even stereophonic recordings of the Philadelphia Orchestra, conducted by Leopold Stokowski.

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

In 1933, the labs published the results of an experimental cable carrier installation at Morristown, New Jersey. The experiment demonstrated multi-channel transmission over cable pairs and helping establish the practical basis carrier telephony systems. A 850 mile circuit with 1300 dB of repeater gain was demonstrated.

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.

1940s

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.

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, arguably the most important invention developed by Bell Laboratories, was invented by John Bardeen, Walter Houser Brattain, and William Bradford Shockley (who subsequently shared the Nobel Prize in Physics in 1956). Also in 1947, Douglas H. Ring of Bell Labs introduced the idea of using hexagonal "cells" to reuse frequencies in mobile radiotelephony, laying the theoretical groundwork for modern cellular networks. The same year, Richard Hamming invented Hamming codes for error detection and correction. For patent reasons, his 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 went much further. 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.

Model I: A complex number calculator, completed in 1939 and put into operation in 1940, for doing calculations of complex numbers.

Model II: Relay Computer / Relay Interpolator, September 1943, for interpolating data points of flight profiles (needed for performance testing of a gun director). This model introduced error detection (self checking).

1950s

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 January 1954, Bell Labs built one of the first completely transistorized computer machines, TRADIC or Flyable TRADIC, for the United States Air Force with 10,358 germanium point-contact diodes and 684 Bell Labs Type 1734 Type A cartridge transistors. The design team was led by electrical engineer Jean Howard Felker with James R. Harris and Louis C. Brown ("Charlie Brown") as the lead engineers on the project, which started in 1951. The device took only 3 cubic-feet and consumed 100 watt power for its small and low powered design in comparison to the vacuum tube designs of the times. The device could be installed in a B-52 Stratofortress Bomber and had a performance up to one million logical operations a second. The flyable program used a Mylar sheet with punched holes, instead of the removable plugboard.

In 1954, the first modern solar cell was invented at Bell Laboratories. The Bell Labs scientists that are credited for inventing the solar cell are Daryl Chapin, Calvin Fuller, and Gerald Pearson.

In 1955, Carl Frosch and Lincoln Derick discovered semiconductor surface passivation by silicon dioxide.

In 1956 TAT-1, the first transatlantic communications cable to carry telephone conversations, 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.

1960s

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.

In December 1960, Ali Javan, PhD physicist from the University of Tehran, 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.

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.

In 1964, the carbon dioxide laser was invented by Kumar Patel and the discovery/operation of the Nd:YAG laser was demonstrated by Joseph E. Geusic et al. Experiments by Myriam Sarachik provided the first data that confirmed the Kondo effect. 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.

In 1965, Penzias and Wilson discovered the cosmic microwave background, for which they were awarded the Nobel Prize in Physics in 1978.

1970s

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

In the 1970s, major central office technology evolved 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.

About 1970, the coax-22 cable was developed by Bell Labs. This coax cable with 22 strands had a total capacity of 132,000 telephone calls. Previously, a 12-strand coax cable was used for L-carrier systems. Both of these types of cables were manufactured at Western Electric's Baltimore Works facility on machines designed by a Western Electric Senior development engineer.

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.

Production of their first internally designed microprocessor, the BELLMAC-8, began in 1977. In 1980 they demonstrated the first single-chip 32-bit microprocessor, the Bellmac 32A, which went into production in 1982.

1980s

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.

In late 1981, the Bell Labs Research organization internal use of a terminal called Jerq led to the Blit terminal being renamed by designers Rob Pike and Bart Locanthi, Jr for the UNIX operating system. It was a programmable bitmap graphics terminal using multi-layers of opened windows operated by a keyboard and a distinguished red-colored three-button digitized mouse. It was later known as the AT&T 5620 DMD terminal for commercial sales. The Blit used the Motorola 68000 microprocessor, whereas the Teletype/AT&T 5620 Dot Mapped Display terminal used the Western Electric WE32000 microprocessor.

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, 336 people have received the honor.

Ken Thompson and Dennis Ritchie were also Bell Labs Fellows for 1982. Ritchie started in 1967 at Bell Labs in the Bell Labs Computer Systems Research department. Thompson started in 1966. Both co-inventors of the UNIX operating system and C language were also awarded decades later the 2011 Japan Prize for Information and Communications.

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 breakup of AT&T, and 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.

1990s

Bell Labs' John Mayo received the National Medal of Technology in 1990.

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.

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.

The scientist, W. Lincoln Hawkins in 1992 received the National Medal of Technology for work done at Bell Labs.

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. Subsequently, the BLAST system proposed by Gerard Foschini and colleagues dramatically expanded the capacity of wireless systems. This technology, known today as MIMO (Multiple Input Multiple Output), was a significant factor in the standardization, commercialization, performance improvement, and growth of cellular and wireless LAN systems.

Amos Joel in 1993 received the National Medal of Technology.

Two AT&T Bell Labs scientists, Joel Engel and Richard Frenkiel, were honored with the National Medal of Technology, in 1994.

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.

21st century

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.

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.

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.

2010s

Gee Rittenhouse, former Head of Research, returned from his position as chief operating officer of Alcatel-Lucent's Software, Services, and Solutions business in February 2013, to become the 12th President of Bell Labs.

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.

On May 20, 2014, Michel Combes, CEO of Alcatel-Lucent, announced the opening of a Bell Labs location in Tel Aviv, Israel by summer time. The Bell Labs research team would be directed by an Israeli computer scientist and alum of Bell Labs, Danny Raz. The Bell Labs research would be in 'cloud networking' technologies for communications. The location would have approximately twenty academic scientific background employees.

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.

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.

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

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.

Antero Taivalsaari became a Bell Labs Fellow in 2016 for his specific work.

2020s

In 2020, Alfred Aho and Jeffrey Ullman shared the Turing Award for their work on compilers, starting with their tenure at Bell Labs during 1967–69.

On, November 16, 2021, Nokia presented the 2021 Bell Labs Fellows Award Ceremony, six new members (Igor Curcio, Matthew Andrews, Bjorn Jelonnek, Ed Harstead, Gino Dion, Esa Tiirola) held at Nokia Batvik Mansion, Finland.

In December 2021, Nokia's Chief Strategy and Technology Officer decided to reorganize Bell Labs in two separate functional organizations: Bell Labs Core Research and Bell Labs Solutions research. Bell Labs Core Research is in charge of creating disruptive technologies with 10-year horizon. Bell Labs Solutions Research, looks for shorter term solutions that can provide growth opportunities for Nokia.

The Nokia 2022 Bell Labs Fellows were recognized on November 29, 2022, in a New Jersey ceremony. Five researchers were inducted to the total of 341 recipients since its inception by AT&T Bell Labs in 1982. One member was from New Jersey, two were from Cambridge, UK, and two were from Finland representing Espoo and Tampere locations.

On November 28, 2023, the Nokia 2023 Bell Labs Fellows were recognized in a ceremony held in Finland. Six honorees were inducted to the total of 347 recipients. Two members were from Murray Hill, New Jersey, one from Munich, Germany, and three were from Finland representing two honorees from Espoo and one honoree from Tampere locations. The Murray Hill location honorees were Randeep Bhatia from Bell Labs Core Research, an author of 40 patent filings and Robert L. Willett from Bell Labs Solutions Research, a 35 year employee concentrating on 2D electron systems.

On December 11, 2023, Nokia announced a state of the art research facility in New Brunswick, New Jersey. The planned relocation of the 80 year old, Murray Hill New Jersey Bell Labs facility would take place before 2028. The new building would be LEED Gold certified. The Murray Hill location has had iconic research of various historical innovations for AT&T Corp., Lucent Technologies, Alcatel-Lucent, and Nokia.

On November 19, 2024, the Nokia 2024 Bell Labs Fellows were recognized in a ceremony held in Lisbon, Portugal. Five honorees were inducted to the total of 352 recipients that include 83 from the Nokia community. Alexei Ashikhmin from Bell Labs Solutions Research represented Murray Hill Bell Labs with more than 25 years as a coding theory researcher.

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.).
