64-460: The Tefifon is an audio playback format , developed and manufactured in Germany, that utilizes cartridges loaded with an endlessly looped reel of plastic tape. It is somewhat similar to the later 4-track and 8-track magnetic audio tape cartridges, but with grooves engraved into the tape, like a phonograph record . The grooves were engraved in a helical fashion across the width of the tape, in

128-645: A 54% share of the Nippon Electric Company, Ltd. Western Electric's representative in Japan was Walter Tenney Carleton . The company, later known as NEC, would eventually become a major international manufacturer of electronics equipment including semiconductors and personal computers. In 1901, Western Electric secretly purchased a controlling interest in a principal competitor, the Kellogg Switchboard & Supply Company , but in 1909

192-664: A Western Electric decision to join Haverhill and Lawrence locations in 1956 as the Merrimack Valley Works. In 1944, Western Electric purchased a factory in St. Paul, Minnesota to restart manufacture of telephone sets for civilian installation as authorized by War Production Board . By 1946, some of these facilities were relocated to the Hawthorne plant as space became available from war-production scale down. Also,

256-416: A cardboard protective case. A Tefifon cartridge would be inserted into the machine, with the reader tape around the capstan . The machine would then be started. The tape would be read with a stylus, which moved across the grooves, in a manner similar to a phonograph record. However, the tape would be stored in a cartridge, like later magnetic tape systems. While there was no way of moving to a specific track,

320-504: A close relationship with telegraph company Western Union , to whom they supplied relays and other equipment. In 1875, Gray sold his interests to Western Union, including the caveat that he had filed against Alexander Graham Bell 's patent application for the telephone . The ensuing legal battle between Western Union and the Bell Telephone Company over patent rights ended in 1879 with Western Union withdrawing from

384-586: A factory at that location and the Western Electric company known as W.E. Mfg. Co., at the time, had purchased Western Union's New York Factory to continue the increase of phone production. This site would also place the end to Western Union factories. The Boston shop was located at 109-115 Court Street and it was previously known as the Charles Williams, Jr factory that was purchased by Western Electric in 1882. The consolidation of operations

448-436: A factory. On August 22, 1952, the facility opened to produce new electronic components for the U.S. government for use by the military and the space program. In the mid-1950s, Western Electric established several more satellite "Shops" that were smaller locations reporting to the larger "Works" locations. The "Montgomery Shops" were occupied in 1955 to produce Data-Phone data sets, wire spring relays, and test sets. Although, it

512-470: A former physics professor at Oberlin College . Barton thought of future growth in electrical apparatus potential for the company and shared a common enthusiasm with the inventor, who was interested in leading a manufacturing plant capable of long-term developments. Shawk found those plans were beyond his business goals and offered to sell his half-interest partnership to Gray. Anson Stager , a former Chief of

576-581: A long radio program is spread over many sides and assembled later on-air to sound as if the whole thing is live. The first Tefifon players and cartridges for home use came available in the German market towards the end of the 1940s, but could not compete with the popular phonographic disc format readily already available at the time. One reason was that well-known artists were committed exclusively by contract to major record companies, most of which had no interest in offering their artists' albums on Tefifon tapes. As

640-511: A manner similar to Dictaphone 's Dictabelt format. The grooves are read with a stylus and amplified pickup in the player's transport . A Tefifon cartridge, known as a "Tefi", can hold up to four hours of music; therefore, most releases for the format are usually compilations of popular hits or dance music , operas , and operettas . Tefifon players were not sold by television and radio dealers in Germany, but rather sold directly by special sales outlets affiliated with Tefi (the manufacturer of

704-515: A meeting of the top executives to decide whether I might remain with the Company, for it established a precedent and a new policy for the Company – that of married women in their employ. If the women at the top were permitted to remain after marriage then all women would expect the same privilege. The policy was expanded quickly, so that a few years later women were given maternity leaves with no loss of time on their service records." Western Electric

768-559: A permanent plant. The 200,000 square-foot leased plant began in June 1971. In 1974, there were 490 IBEW employee members on strike over local agreement issues. In 1975, this San Ramon Valley Plant announced a September 30 closure of its telephone transmission equipment manufacturing operations. On January 27, 1983, the Kearny facility was announced for closure due to technology changes, underutilized, and too costly to maintain. The phase out of

832-470: A result, most Tefifon releases were of relatively unknown bands and artists. In addition, the Tefifon saw competition from phonographs equipped with record changers , some of which could allow for up to three hours of music without interruption. The Tefifon was offered in the 1950s as a standalone device, but also in combination with various types of radios, including portable and home models. The chassis of

896-667: A section chief and one maintenance man. In 1955, the Lawrence plant reached its peak employment at more than 2,000 employees. This Bell Labs research and development satellite had 40 Bell Telephone Laboratories engineers and 25 Western Electric employees.

1024-470: A statue originally named Electricity , but later renamed Spirit of Communication , which was raised to the roof of 195 Broadway on October 24, 1916. In 1915, the assets of Western Electric Manufacturing were transferred to a newly incorporated company in New York, New York , named Western Electric Company, Inc , a wholly owned subsidiary of AT&T. The sole reason for the transfer was to provide for

1088-487: A telephone not supplied by the Bell System had to first transfer the phone to the local Bell operating company, who leased the phone back to the customer for a monthly charge in addition to a re-wiring fee. In the 1970s when consumers increasingly bought telephone sets from other manufacturers, AT&T changed the policy for its Design Line telephone series by selling customers the phone housing, retaining ownership of

1152-432: A variety of audio formats, some of which store additional information. Recorded two tracks on both stereo channels, requiring a decoder to hear all four tracks. Despite this, the format is playable on any LP turntable. This audio format famously caused controversy among recording companies when released due to the potential of perfect digital copies to increase piracy Western Electric Western Electric Co., Inc.

1216-551: The 1920s. In 1923, construction began on the second factory located in Kearny, New Jersey . The location was known as Kearny Works and in 1925 began telephone cable production. On June 15, 1928, Western Electric employees, photographed by Rosenfeld and Sons, were pictured, in a groundbreaking ceremony , for their expansion of the Kearny Works manufacturing facility at 110 Central Ave, Kearny, New Jersey. Kearny Works would achieve

1280-442: The 4-hour Tefi cartridges recorded at 19 CPS (7-1/2 IPS) could carry 4 hours, the talking book could carry twice that, or eight hours. With no way to get an eight-hour recording done all in one session with no mistakes, these extremely long programs were transcribed first onto 15-minute cartridges (30 minutes of Talking Book) and later 1-hour cartridges (2-hour Talking Book) and then assembled by playing them back in succession much as

1344-510: The Tefifon format was in 1961, with the introduction of stereo sound , but this was not commercially successful. Tefifon production at its main plant in Porz am Rhein was halted in 1965. Afterward, the rights to the name were acquired by the Neckermann mail-order company, which also took over the sale of existing Tefifon products. Even though the Tefifon was little-known outside of Germany, it

1408-524: The U.S. Military Telegraphs during the American Civil War , advanced money for Gray to buy the half-interest and become a partner when Gray and Barton moved operations to Chicago . Gray and Barton previously knew Stager and an agreement was signed on November 18, 1869, to launch the company as Gray & Barton. The firm was open for business by the end of the year in Chicago. In December 1869,

1472-538: The United States for much of the 20th century, Western Electric's equipment was widespread across the country. The company was responsible for many technological innovations, as well as developments in industrial management. In 1856, George Shawk, a craftsman and telegraph maker, purchased an electrical engineering business in Cleveland, Ohio . In January 1869, Shawk had partnered with Enos M. Barton in

1536-459: The Western Electric brand. Early on, Western Electric also managed an electrical equipment distribution business, furnishing its customers with non-telephone products made by other manufacturers This electrical distribution business was spun off from Western Electric in 1925 and organized into a separate company, Graybar Electric Company , in honor of the company's founders, Elisha Gray and Enos Barton. Bell Telephone Laboratories , created from

1600-406: The construction of Hawthorne Works first buildings were authorized by Barton. In 1907, the research and development staffs of Western Electric and AT&T were consolidated to 463 West Street, New York. The location served the newly Western Electric Engineering Department for the responsibility of the testing and inspection of its telephones and equipment. AT&T's Engineering Department retained

1664-405: The data. Note on the use of analog compared to digital in this list; the definition of digital used here for early formats is that which is represented using discrete values rather than fluctuating variables. A piano roll is digital as it has discrete values, that being a hole for each key, unlike a phonograph record which is analog with a fluctuating groove. Music is recorded and distributed using

1728-494: The engineering department of Western Electric in 1925, was half-owned by Western Electric, the other half belonging to AT&T. The company began to increase its presence in other sectors of industry for new products. In September 1931, the Teletype Corporation headquartered in Chicago on Wrightwood Ave, became a subsidiary of Western Electric and it was a manufacturer of teletypewriters for TWX services. There

1792-448: The facility jobs started in fall of 1983 and the 59 year old, 3 million-square-foot, 144-acre facility was sold officially on May 21, 1984, with nearly 1000 last employees left at the plant. The former facility was purchased and later existed as warehouses, distribution, research and light manufacturing facilities. As modern facilities around the country were used for the operations of Hawthorne and its productions distributed, announcement

1856-412: The format). The Tefifon format was developed by the German entrepreneur Dr. Karl Daniel and his "Tefi" company in 1936. A few years earlier, devices using phonographic grooved tape like the Tefifon were produced by Tefi for special purposes, like the military, and were designed for voice recording . Prior to the Tefifon's introduction, Tefi had introduced a device capable of recording and playback under

1920-464: The former Western Union repair shop of Cleveland, to manufacture burglar alarms, fire alarms, and other electrical items. Both men were former Western Union employees. Shawk, was the Cleveland shop foreman and Barton, was a Rochester, New York telegrapher. During this Shawk and Barton partnership, one customer was an inventor sourcing parts and models for experiments. That inventor was Elisha Gray ,

1984-492: The headquarters in Chicago had moved to a new building on Clinton Street, the New York shop had moved two city blocks to a new building on Greenwich Street, and both Boston and Indianapolis factories closed. The Antwerp location was at the same location under Western Electric operations until sold in 1925 to ITT. In April 1879, the New York shop was located at 62-68 New Church Street, Lower Manhattan, New York. Western Union had

The Kansas City Works location was in Lee's Summit, Missouri . A Lawrence, Massachusetts factory opened on November 13, 1951, and was called the "Garfield Shops." The location started with as a wired units job and there were thirteen workers with

2112-550: The internal mechanical and electrical components, which still required paying AT&T a monthly leasing fee. Starting in 1983 with the breakup of the Bell System, Western Electric telephones could be sold to the public under the brand name American Bell, a newly created subsidiary of AT&T. One of the terms of the Modification of Final Judgment in the Bell System divestiture procedures prohibited AT&T from using

2176-444: The issuance of a non-voting preferred class of capital stock, disallowed under the statutes of the state of Illinois. In the Bell System, telephones were leased by the operating companies to subscribers, and remained the property of the Bell System. Service subscribers paid a monthly fee included in the service charge, while paying additionally for special types or features of telephones, such as colored telephone sets. Equipment repair

Here is an aerial image of Kearny Works, between 1925 and 1930, held in the Library Company of Philadelphia. with the picture of the entire plant and railways. In 1929, work began at Point Breeze, Baltimore, Maryland as

2304-591: The location was at 162 South Water Street in Chicago. On December 31, 1869, he entered a partnership with Barton, and later sold his share to inventor Gray. In 1872, Barton and Gray moved the business to Clinton Street, and incorporated it as the Western Electric Manufacturing Company on the Near West Side of Chicago. They manufactured a variety of electrical products including typewriters, alarms, and lighting and had

2368-560: The name Bell after January 1, 1984; prior to this, AT&T's plan was to market products and services under the American Bell name, accompanied by the now familiar AT&T globe logo. In 1903, Western Electric began construction of the first buildings for Hawthorne Works on the outskirts of Chicago . In 1905, the Clinton Street power apparatus shops moved to Hawthorne. Further expansion of large factories began in

2432-442: The name "Tefiphon" (note the alternate spelling) and another device only capable of playback under the name "Teficord". Both use loose tape, unlike the cartridge-loaded tape of the Tefifon. In 1937, a half-speed 9.5 CPS (3-3/4 IPS) format was developed for talking books for the blind in the early run-up to World War II . This was continued, albeit scaled back until vinyl disc technology could catch up in quality if not time, since

2496-479: The operations for pulp cable relocated to Phoenix Works. A loss of 400 positions were expected eliminated in the process. After the Bell System breakup, Western Electric facilities were known as AT&T Technologies facilities in 1984. The three largest and oldest facilities, Hawthorne Works, Kearny Works, and Baltimore Works were closed shortly after due to "excess space". Western Electric used various logos during its existence. Starting in 1914 it used an image of

2560-456: The radio sets were often purchased ready-made from third parties, with a Tefifon playback transport being added to it as a finished product. The sound quality of Tefifon tapes is superior to 78 rpm records made of shellac , but is still less than that of 33 rpm LP records made of vinyl . In addition, the mechanical stress on the stylus and supporting cantilever is quite strong, so this wears out relatively quickly. The last innovation of

2624-612: The reduced production of home telephones because of the war, began to have a backlog of two million orders in late 1945 for the Hawthorne plant. Western Electric had acquired a former Studebaker plant on Archer Avenue (Chicago, Illinois) for assemblers that produced out one hundred thousand Model 302s telephones by March 1946. After World War II, the National Carbon Company left a facility that had manufactured United States Navy submarine batteries and underwater detonators in Winston-Salem. This facility at 800 Chatham Road,

On July 24, 1915, employees of the Hawthorne Works boarded the SS Eastland in downtown Chicago for a company picnic. The ship rolled over at the dock and over 800 people died. In 1920, Alice Heacock Seidel

2752-422: The stylus could be moved to a variety of positions on the tape. Timeline of audio formats An audio format is a medium for sound recording and reproduction . The term is applied to both the physical recording media and the recording formats of the audio content —in computer science it is often limited to the audio file format , but its wider use usually refers to the physical method used to store

2816-417: The telephone market and Bell acquiring Western Electric in 1881. This purchase was a crucial step in standardizing telephone instruments and concentrating manufacturing in a single entity. In the company's first few years as Western Electric, there were five manufacturing locations located at Chicago (220-232 Kinzie St.) New York, Boston, Indianapolis and Antwerp, Belgium. The locations were not permanent, as

2880-464: The third manufacturing location, Baltimore Works, began its occupancy by 1930 for various cable and wire production. Two manufacturing plants in Lincoln, Nebraska were leased in 1943 to Western Electric to manufacture signal corps equipment and later production demands from Hawthorne Works. The Eighth Street building, known as "Lincoln Shops," and the 13th Street building were the locations, the latter

2944-539: The three oldest manufacturing facilities for product manufacturing transfers and employee expected layoffs. The Kearny Works facility that made systems to convert commercial power to run various telecom equipment, would transfer remaining work to Dallas Works. The shutdown of the plant would eliminate 4,000 jobs. The Baltimore Works facility that made connectors and protectors for wire and cable had work moved to Omaha Works. A total of 2,300 jobs were potentially eliminated after that announcement. The Hawthorne Works facility, had

3008-519: The variety of new designs introduced into the market place. This led Western Electric to pursue extreme reliability and durability in design to minimize service calls. In particular, the work of Walter A. Shewhart , who developed new techniques for statistical quality control in the 1920s, helped lead to the quality of manufacture of Western Electric telephones. AT&T also strictly enforced policies against using telephone equipment by other manufacturers on their network. A customer who insisted on using

3072-668: Was agreed on September 3, 1974, with employees at 13 plants returning to work. Only the company's subsidiary Teletype Corporation plant in Little Rock, Arkansas and two plants, the Columbia River Switching Equipment factory in Vancouver, Washington and in San Ramon, California were subject to ratification or in negotiations to settle local agreements. In 1983, corporate announcements were made at

A subsidiary of the AT&;T Corporation for most of its lifespan, Western Electric was the primary manufacturer, supplier, and purchasing agent for all telephone equipment for the Bell System from 1881 until 1984, when the Bell System was dismantled . Because the Bell System had a near-total monopoly over telephone service in

3200-703: Was called "Buffalo Plant." A satellite shop was established in Jersey City, New Jersey called "Marion Shops" and occupied in 1947. This location produced portable test sets, rectifiers, and power equipment for the main plant known as the Kearny Works. In July 1948, the equipment plant at Duluth, Minnesota was involved in the National Labors Act with bargaining units of IAM and IBEW. After 1947, eight Works locations were built and occupied by 1961 at Allentown, Indianapolis, North Carolina, Merrimack Valley, Omaha, Columbus, Oklahoma City, and Kansas City for

3264-621: Was done in 1884 to Chicago and New York factories by Charles Williams becoming a Western Electric Manager. In 1888–1889, Western Electric built a 10-story factory building at 125 Greenwich Street in Lower Manhattan, to manufacture some of the first telephones. The New York shop that was renting the Western Union building moved to this building. In preparation for the Chicago Worlds Fair of 1892, Western Electric

3328-606: Was expanding beyond making telephone equipment and American Bell noticed its division from a manufacturing business to a supply business. Western Electric decided to split in 1921, the supply department from the manufacturing business and this led later to a separate entity. In 1925, ITT purchased the Bell Telephone Manufacturing Company of Brussels, Belgium, and other worldwide subsidiaries from AT&T, to avoid an antitrust action. The company manufactured rotary system switching equipment under

3392-559: Was forced by a lawsuit to sell back to Milo Kellogg. The Manufacturers Junction Railway Company was incorporated in January 1903 to provide rail connections to major railroad systems. There were approximately 13 miles of track in and out of Hawthorne Works for rail freight of inbound materials and outbound finished products. Western Electric had a tenure of 50 years up to 1952, in the responsibility and operation of its use for Hawthorne and other nearby industrial companies. Also, in 1903,

3456-412: Was imported and sold in the United States for a very short time by Western Electric 's Westrex division from 1963 to 1964 under the "Westrex" name. Tefifon cartridges were made in four sizes: The larger cartridge also had several differences from the smaller units. It featured a spring to assist in removing the tape for playback, and a plastic cover over the tape to protect it. The cartridges also have

3520-576: Was included in the fees. This system had the effect of subsidizing basic telephone service, keeping local telephone service inexpensive, under $ 10 per month. After divestiture, basic service prices increased, and customers became responsible for inside building wiring and telephone equipment. The Bell System had an extensive policy and infrastructure to recycle or refurbish equipment taken out of service, replacing all defective, weak, or otherwise unusable parts for new installations. This resulted in extraordinary longevity of Western Electric telephones, and limited

3584-612: Was located in Montgomery, Illinois, it reported and supported production of the main plant, Hawthorne Works in Cicero, Illinois. The Kearny Works facility had satellite shops that were apart from its location but were part of the manufacturing process. Located in Fair Lawn, New Jersey and occupied since 1956, the "Fair Lawn Shops" produced coils, resistors, transformers, and keys under Kearny manufacturing. The Indianapolis Works facility

3648-611: Was made on June 24, 1983, for closure. Between 1975 and 1983, the Foundry and most of the Telephone Apparatus buildings were demolished and in 1986–1987, the remaining Telephone Apparatus buildings and the Executive Tower were demolished. The Hawthorne facility was in operations for 83 years when it closed its doors in 1986 and torn down for a shopping center. Another building was demolished on April 10, 1994, for

3712-441: Was passed to Western Electric Company and operated until 1966 for production of national telephone companies' switches and circuits. Additionally, the location complex was one of three nationwide Western Electric field engineering sites. The mid-1940s brought occupancy to locations. A plant was established in 1946 at Tonawanda, New York to produce equipment wiring cable, telephone cords, enamelled wire, and insulated wire. This plant

3776-477: Was producing telephone sets and components with a satellite shop. The Indianapolis shop known as "Washington Street Shop" produced miscellaneous subscriber apparatus since its occupancy in 1957. The "Lawrence Shop" that was occupied in 1957 produced BELLBoy receivers, telephone repeaters and carrier products under Merrimack Valley Works. The "Clark Shop" was occupied in 1959 at Clark, New Jersey and manufactured submarine cable repeaters and components. The satellite shop

3840-419: Was responsible for the organized Bell System sales activities and merchandising of apparatus for the 900 long-distance circuit from New York to Chicago. In 1897, the building at 463 West Street, New York was constructed and housed the New York shop as well as the company Eastern headquarters. Western Electric was the first company to join in a Japanese joint venture with foreign capital. In 1899, it invested in

3904-488: Was sold in 1950 for $ 500,000 to Western Electric. The plants were closed after the Omaha Works opened in 1958. Western Electric acquired in 1943, the old Grad and Winchell buildings located at Haverhill, Massachusetts. New Jersey supervisors taught former textile and shoe workers the manufacturing process of coil winding. The employees' acquired skills demonstrated their versatility in this new manufacturing process for

The acquisition of the Queensboro factory in Middle Village, New York became a Western Electric Shop in the 1930s to produce wooden telephone booths. In 1974, the IBEW members at Western Electric's 16 plants went on strike over improved benefits, cost‐of‐living adjustments, and pay increase for up to three years. The ratified contract

4032-432: Was the first female Western Electric employee to be given permission to stay on after she had married. This set a precedent in the company, which previously had not allowed married women in their employ. Miss Heacock had worked for Western Electric for sixteen years before her marriage, and was at the time the highest-paid secretary in the company. In her memoirs, she wrote that the decision to allow her to stay on "required

4096-486: Was under Kearny Works. The 1960s and 1970s had various new facilities built and occupied by Western Electric to produce new technologies such as electronic switching equipment (Dallas and North Illinois), fiber optic cable networks (Atlanta), power systems (Phoenix), business equipment (Denver), and telephone equipment (Shreveport). In 1970, Western Electric purchased land in Bishop Ranch, San Ramon, California for
