Morse and the
Telegraph
This month marks the 200th anniversary of the birth
of Samuel F. B. Morse, who was born April 27, 1791, in Charlestown, Massachusetts.
It seems an appropriate occasion for some reflections on the famous
artist-inventor and the electrical communication system that he and his
associates developed.
Morse's father, Jedediah, was a leader in the
Congregational church who also authored geography books, causing his son to
gain the nickname, "Geography Morse." Samuel Morse graduated in 1810
from Yale, where he acquired some knowledge of electrical science from Benjamin
Silliman, Jeremiah Day, and Sereno Dwight. Morse's early career was devoted to
art, and he managed to spend about four years in Europe where he was tutored in
art by Benjamin West. Morse returned to Massachusetts in 1815 and enjoyed some
success as a painter of portraits but not of the large historical painting he
preferred. In 1825, he moved to New York City where he and other artists
founded the National Academy of Design, with Morse serving as its president. In
1827, he attended lectures on the relatively new science of electromagnetism
given by James F. Dana of Columbia College.
In 1829, Morse again went to Europe where he worked
and studied art for nearly three more years. Among his major projects was a
painting known as the Gallery of the Louvre that sold for $1200 in 1835. (In
July 1982, this painting was sold for $3.25 million, reported to have been the
highest price ever for an American painting at the time.) In 1832, Morse took a
position as professor of painting and sculpture at New York University. He
conducted two unsuccessful campaigns for mayor of New York City in 1836 and
1841.
In a frequently cited paper published in 1977, the
historian of technology, Eugene S. Ferguson, stressed the importance of
nonverbal thought in technology, a concept that has since become a popular
interpretive theme. In his book, Emulation and Invention, Brooke Hindle pointed
out the importance of nonverbal thought in understanding Morse's success as an
inventor. Hindle noted that Morse's exceptional ability to think spatially and
to visualize in his mind alterations in paintings also became manifest in his
work on telegraphic devices and systems.
Morse used his art studio at New York University as
a telegraph laboratory for his early experiments. He received important
assistance from Leonard D. Gale, professor of geology and mineralogy at the
university. Gale helped with construction of batteries and informed Morse of
related work by Joseph Henry, a leading American authority on electromagnetism.
Alfred Vail, who graduated from New York University
in 1836, became a participant in development of the Morse telegraph in
September 1837. Members of the Vail family owned the Speedwell Ironworks in
Morristown, New Jersey, and they provided both financial and technical
assistance to the project. The first public demonstration of the Morse system
took place in January 1838 at Speedwell, with signals received over a two-mile
line. (The significance of this demonstration was recognized as an electrical
engineering milestone in a dedication ceremony at Historic Speedwell in May
1988. This was part of an ongoing milestone program supervised by the IEEE
History Committee and administered by the Center for History of Electrical
Engineering.)
Morse received a telegraph patent in 1840 and in
1843 was recipient of a $30000 grant from the federal government to be used to
build a telegraph line between Washington, D.C. and Baltimore, Maryland. The
famous "What hath God Wrought" message was transmitted over this line
on May 24, 1844. Morse's effort to sell his system to the United States government
failed, and the Magnetic Telegraph Company was founded in 1845 to being
building a telegraphic network. By 1848, every state east of the Mississippi
except Florida was linked by telegraph lines, and there were more than 23000
miles of telegraph wire in the United States by 1852. Morse disclosed in 1853
having received $193 000 in income from telegraphy as a shareholder in several
firms. The Western Union Company, formed in 1856, achieved dominance in
American telegraphy in the post Civil War period and handled 92 per cent of
telegraphic traffic in 1880. The first transcontinental telegraph line was
completed in October 1861. (This achievement also was recognized as an
electrical engineering milestone at a dedication ceremony at the Fort Laramie
National Historic Site in Wyoming in August 1990).
The telegraph served an important command and
control function for both sides during the American Civil War. Telegraphic
communication also facilitated control of railroad ,traffic, news gathering,
time standardization, and numerous other business and governmental activities.
The Western Union president, William Orton, told a congressional committee in
1870 that the "telegraph lives upon commerce" and "it is the
nervous system of the commercial system."
The first transatlantic telegraph cable was
completed in 1858, although it failed after a few weeks. After the Civil War, a
new transatlantic cable was laid successfully in 1866. (This extraordinary
technological achievement was recognized as an international electrical engineering
milestone in a ceremony at the Heart's Content cable station in Newfoundland,
Canada, in June 1985).
Samuel Morse died in 1872, but he had lived to see
the installation of a network of telegraph lines and cables connecting cities
and towns around the world. The time required to communicate between London and
New York City has been reduced from approximately two weeks to the speed of
electrical impulses through a submarine cable. Morse's telegraph and the Morse
code established the precedent of the binary mode of information exchange that
has become so ubiquitous in our own age of digital computers and
telecommunications networks. Perhaps some older readers still remember a time
when it was common practice to send important personal messages by telegram and
when the Western Union office was a communication center in every city and
town.
