1837: Telegraph invented |
The term "Telegraph" is derived from the greek "tele" which means far and "graphein" which means to write. [Telegraph and Beyond]
1826 - 31: Optical telegraph lines operated in Europe, and in a few locations in the United States: New England, Philadelphia, and San Francisco [Starr p 157][Wired Prof]
1832: Samuel FB Morse conceives of idea of electromagnetic telegraph. [Smithsonian][Starr p 158]
"Samuel F. B. Morse , [Portrait to Morse] while a professor of arts and design at New York University in 1835, proved that signals could be transmitted by wire. He used pulses of current to deflect an electromagnet, which moved a marker to produce written codes on a strip of paper -the invention of Morse Code. The following year, the device was modified to emboss the paper with dots and dashes.
1837:
- Sept 4: Morse transmits over 1700 feet of wire wrapped around in his classroom.
- Morse filed a Caveat for his invention with the Patent and Trademark Office. [SI] Morse gives first public demonstration of telegraph. [Starr p 158]
- Charles Wheatstone and William Fothergille Cooke obtained a british patent for a needle telegraph. [Starr p 158]
1838: Morse forms a company around his telegraph invention with Alfred Vail and Leonard Gale. [Smithsonian][Starr p 160]
Disruptive Technology: "Telegraphy became big business as it replaced messengers, the Pony Express, clipper ships and every other slow paced means of communicating. The fact that service was limited to Western Union offices or large firms seemed hardly a problem. After all, communicating over long distances instantly was otherwise impossible. Yet as the telegraph was perfected, man's thoughts turned to speech over a wire." [Farley]
"He gave a public demonstration in 1838, but it was not until five years later that Congress -- reflecting public apathy -- funded $30,000 to construct an experimental telegraph line from Washington to Baltimore, a distance of 40 miles." Morse origianlly attempted to construct the lines underground using Ezra Cornell's trench digger invention. This proved unsuccessful, therefore Morse switched to installing telegraph poles. [Smithsonian] [Starr p 157]
1838: William Cooke and Charles Wheatstone initiate commercial electric telegraph service in England. [White]
"Six years later, members of Congress witnessed the sending and receiving of messages over part of the telegraph line. Before the line had reached Baltimore, the Whig party held its national convention there, and on May 1, 1844, nominated Henry Clay. This news was hand-carried to Annapolis Junction (between Washington and Baltimore) where Morse's partner, Alfred Vail, wired it to the Capitol. This was the first news dispatched by electric telegraph.
Source: Library of Congress (large resolution)
"The message, "What hath God wrought?" sent later by "Morse Code" from the old Supreme Court chamber in the United States Capitol to his partner in Baltimore, officially opened the completed line of May 24, 1844.[SI] Morse's second transmission that day was "Have you any news?" [Hochfelder 310]
"Three days later the Democratic National Convention was held in Baltimore. Van Buren seemed the likely choice, but his opponent, James K. Polk, won the nomination. This news was telegraphed to Washington, but skeptics refused to believe it. Only after persons arrived by train from Baltimore to confirm the reports were many convinced of the telegraph's value.
| 1851 - 51 telegraph companies [Alven] |
"Samuel Morse and his associates obtained private funds to extend their line to Philadelphia and New York. Small telegraph companies, meanwhile began functioning in the East, South, and Midwest.

1845: Morse and his partners form the Magnetic Telegraph Company. [Smithsonian]
1846: The Magnetic Telegraph Company constructs the first commercial telegraph line between Washington D.C. and New York City. [Smithsonian]
Much of the telegraph lines are constructed along railway ROW. There is a strong symbiotic relationship. The telegraph operators gain access of long rights of way, that connect major population centers. The railroads gain use of the communications network, helping them coordinate train traffic and take advantage of single track lines - instead of two tracks, one for each direction - saving in capital costs. As a result, telegraph companies indirectly benefited from the land grants that the federal government gave to the railroads.

1850 "Period of Wasteful Competition" [Hochfelder 310]
1851 Judge Samuel Selden and Hiram Sibley formed the New York and Mississippi Valley Printing Telegraph Company (NY&MI) with the goal of acquiring and uniting otherwise non-interconnected rival telegraph companies. (See AT&T Vail and Universal Service). Sibley proceeded to acquire companies westard. [Smithsonian]

1854:
- "In 1854, Sibley acquired the Morse patent rights for the Midwest from Jeptha Wade and John Speed for $50,000. The NY&MI company proceeded to migrate to the superior Morse Code system." See [Smithsonian]
- Atlantic and Pacific Telegraph Company incorporated in Maine. [NYT Mach 31, 1954

1856: NY&MI becomes Western Union. [Smithsonian] [Brooks p 62]
1860: The Pacific Telegraph Act is enacted authorizing the construction of a transcontinental telegraph. Western Union wins the contract. [Smithsonian] "Western Union built its first transcontinental telegraph line in 1861, mainly along railroad rights-of-way." Western Union becomes the United States first truly nationwide company.

- Post Roads Act of 1866 (granting telegraph companies right to operate over federal lands)
"During the Civil War, Western Union's lines were primarily in the North. Carriers with lines in the South experienced substantial damage as a result of the war. Carriers with lines in both the North and the South saw their assets and their business split into two. During the war, the military constructed 15,000 miles of telegraph line - that was later ceded to Western Union as compensation for damages; Western Union experienced substantial profits as a result of wartime business. When the war stopped and demand for telegraph decreased sharply, smaller carriers went out of business. "After the Civil War, the three major telegraph companies were Western Union, American Telegraph and United States Telegraph. Through a series of stock swaps, Western Union acquired both of the other companies and established itself as a monopoly. |
US Senate: Art & History Home: History Minutes > 1851-1877 > Telegraph 1866 "Telegraph"
The Vatican fresco artist Constantino Brumidi came to the United States from Italy in 1852 looking for work. Brumidi had the good fortune of arriving in Washington just as the superintendent of the project to construct new wings for the Capitol was looking for skilled artists. From the mid 1850s until his death twenty-five years later, he earned the title "Michelangelo of the Capitol." His great contribution was to integrate American themes into the classical style of the Italian Renaissance. Some of Brumidi's best work exists in the second-floor room now named in honor of former Senate Majority Leader Lyndon Johnson Brumidi took particular interest in that prime space, intended to serve as the Senate Library. To emphasize the theme of learning, he designed four semi-circular lunettes in the ceiling to represent major fields of knowledge-History, Geography, Philosophy, and-recognizing that era's technological expansion in the production of newspapers and journals-the field he called Print. He completed the first painting, Geography, in 1858. A year later, as the Senate moved into its newly completed chamber, members decided that they needed a conveniently located post office more than a library. As workmen installed individual mail boxes for each of the Senate's sixty-six members, Brumidi shifted his attention to other assignments. In 1866, with the war over, the artist returned to complete the room's decoration, including the remaining three ceiling lunettes. Originally, he had planned to decorate one of those spaces to honor the medium of Print. But the shift in the room's function from a library to a post office, along with the excitement surrounding the successful laying of a trans-Atlantic telegraph cable that year, changed the theme to Telegraph. (In this same spirit of scientific innovation, he also changed the Philosophy panel to Physics.) Intensely proud of his new country, the artist took a bit of patriotic license. Although the telegraph cable was laid from Europe to America -from Ireland to Newfoundland -he reversed the direction. At the center of the fresco appears a nymph, who is handing the telegraph wire to the allegorical figure for Europe on the left. With a grateful countenance, Europa looks up to a strong America surrounded by images that suggest the nation's natural abundance and its military might. In the year 1866, however, that image of America 's strength as a world power lay mostly within the colorful imagination of Constantino Brumidi |

Associated Press
Western Union was establishing its monopoly for telegraph; Associated Press was establishing its monopoly for news. In 1867 the two came to an agreement which strengthened their respective holds on their markets.
- AP agreed to only use Western Union lines - not any competitors,and gave up its own telegraph interests
- AP received a preferential rate over rival or independent news sources
- AP would not "encourage or support any opposition or competing telegraph company."
- AP newspapers would only use AP; new newspapers could only join with the approval of existing newspapers.
- To criticize AP would be to risk access to the news content, and to Western Union. You could not criticize Western Union and you could not criticize AP.
- Non-AP news organizations could not gain access to the telegraph lines and therefore could not succeed.
- Western Union, after supporting the Republicans during the civil war and receiving 15,000 miles of telegraph line after the war, was decisively pro-republican.
Reformers would try to break the monopolistic hold of both companies for decades. A repeated argument was that the telegraph service should rightfully be made a part of the US Postal Service. [Ars Technica] [Hochfelder 310] According to Hochfelder,
"Although reformers failed to reach their ultimate goal, the end of Western Union's monopoly over telegraphic communications, they achieved some lasting success. By calling for increased government involvement in economic affairs and in securing citizen's access to communications networks, they constructed an important part of Progressive economic thought. By the 1890s, their efforts helped to establish regulation as an acceptable middle ground between state ownership of a networked technology and its operation by untrammeled private capitalists. [Hochfelder 312]

1876:
- In the disputed election of 1876, there was uncertainty whether the democrats of the republicans had won the electoral college votes from Florida, Louisiana, and South Carolina. Republicans quickly took advantage of the telegraph services of pro-republic Western Union. " During the long controversy in Congress over who actually won the districts in the disputed election of 1876, Western Union secretly siphoned to AP's general agent Henry Nash Smith the telegraph correspondence of key Democrats during the struggle. Smith, in turn, relayed this intelligence to the Hayes camp with instructions on how to proceed. On top of that, AP constantly published propaganda supporting the Republican side of the story. Meanwhile, Western Union insisted that it kept "all messages whatsoever . . . strictly private and confidential." " [Ars Technica]

"The original Morse telegraph printed code on tape. However, in the United States the operation developed into sending by key and receiving by ear. A trained Morse operator could transmit 40 to 50 words per minute. Automatic transmission, introduced in 1914, handled more than twice that number.
"In 1913 Western Union developed multiplexing, which it made possible to transmit eight messages simultaneously over a single wire (four in each direction).
"In a 1918 Joint Resolution, Congress authorized the President to assume control of any telegraph system in the United States and operate it as needed for the duration of World War I." [2009 Review]
Western Union Teleprinter machines came into use about 1925.
Varioplex, introduced in 1936, enabled a single wire to carry 72 transmissions at the same time (36 in each direction). Two years later Western Union introduced the first of its automatic facsimile devices.

1959: Western Union inaugurated TELEX, which enables subscribers to the teleprinter service to dial each other directly.
OCEAN CABLE TELEGRAPH
"With capital obtained from private subscriptions in New York and London and, in part, appropriated by the British and United States governments, an attempt was made in 1857 to lay a cable under the Atlantic Ocean. The cable broke after 355 miles has been laid by a ship operating from Ireland. The following June, another attempt failed. A cable was thought to be successfully laid the next month but it became inoperative. Another cable-laying effort, in 1865, proved futile after the many attempts made.
"On July 27, 1866, the steamship "Great Eastern" completed laying a new cable from Ireland to Newfoundland. Returning to mid-Atlantic, the ship located and raised the cable used in a previous attempt, spliced it, and extended it to Newfoundland, where it was landed on September 8, 1866. Thus, America and Europe were linked by two cables and other ocean cables followed.
"Ocean cables were operated by repeating the messages along the route. In 1921, "regenerators" were developed for direct transmission between terminals. Less than 300 single letters a minute could be sent over the original transatlantic cable. Later new "permalloy" cables raised that capacity to about 2,400 letters a minute.
"Until 1877, all rapid long-distance communication depended upon the telegraph. That year, a rival technology developed that would again change the face of communication -- the telephone. By 1879, patent litigation between Western Union and the infant telephone system was ended in an agreement that largely separated the two services.
. . . . .
RADIO TELEGRAPH
"Few radio broadcasts travel through the air exclusively, while many are sent over telephone wires. In the 1860s James Clerk Maxwell, a Scottish physicist, predicted the existence of radio waves, and in 1886 Heinrich Rudolph Hertz, a German physicist, demonstrated that rapid variations of electric current could be projected into space in the form of radio waves similar to those of light and heat.
"But it remained for Guglielmo Marconi, an Italian inventor, to prove the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful transatlantic radiotelegraph message in 1902.
"Wireless signals proved effective in communication for rescue work when a sea disaster occurred. Effective communication was able to exist between ships and ship to shore points. A number of ocean liners installed wireless equipment. In 1899 the United States Army established wireless communications with a lightship off Fire Island, New York. Two years later the Navy adopted a wireless system. Up to then, the Navy had been using visual signaling and homing pigeons for communication.
"In 1901, radiotelegraph service was instituted between five Hawaiian Islands. By 1903, a Marconi station located in Wellfleet, Massachusetts, carried an exchange or greetings between President Theodore Roosevelt and King Edward VII. In 1905 the naval battle of Port Arthur in the Russo-Japanese war was reported by wireless, and in 1906 the U.S. Weather Bureau experimented with radiotelegraphy to speed notice of weather conditions.
"In 1909, Robert E. Peary, arctic explorer, radiotelegraphed: "I found the Pole". In 1910 Marconi opened regular American-European radiotelegraph service, which several months later, enabled an escaped British murderer to be apprehended on the high seas. In 1912, the first transpacific radiotelegraph service linked San Francisco with Hawaii.
"Overseas radiotelegraph service developed slowly, primarily because the initial radiotelegraph set discharged electricity within the circuit and between the electrodes was unstable causing a high amount of interference. The Alexanderson high-frequency alternator and the De Forest tube resolved many of these early technical problems. The Navy made major use of radio transmitters -- especially Alexanderson alternators, the only reliable long-distance wireless transmitters - for the duration.
"During World War I, governments began using radiotelegraph to be alert of events and to instruct the movement of troops and supplies. World War II demonstrated the value of radio and spurred its development and later utilization for peacetime purposes. Radiotelegraph circuits to other countries enabled persons almost anywhere in the United States to communicate with practically any place on earth.
"Since 1923, pictures have been transmitted by wire, when a photograph was sent from Washington to Baltimore in a test. The first transatlantic radiophoto relay came in 1924 when the Radio Corporation of America beamed a picture of Charles Evans Hughes from London to New York. RCA inaugurated regular radiophoto service in 1926.
"Two radio communication companies once had domestic networks connecting certain large cities, but these were closed in World War II. However, microwave and other developments have made it possible for domestic telegraph communication to be carried largely in part over radio circuits. In 1945 Western Union established the first microwave beam system, connecting New York and Philadelphia. This has since been extended and is being developed into a coast-to-coast system. By 1988 Western Union could transmit about 2,000 telegrams simultaneously in each direction.
