Samuel Morse



While teaching arts and design at New York University in 1835, Morse 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. This led to the invention of Morse Code.



The following year, the device was modified to emboss the paper with dots and dashes. He gave a public


demonstration in 1838, but it wasn't until five years later that Congress, reflecting public apathy, awarded him 


$30,000 to construct an experimental telegraph line from Washington to Baltimore, a distance of 40 miles.



Six years later, members of Congress witnessed the transmission of messages over part of the telegraph line.


Before the line had reached Baltimore, the Whig party held its national convention there and nominated


Henry Clay on May 1, 1844. The 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.



What Hath God Wrought?



The message "What hath God wrought?" sent by "Morse Code" from the old Supreme Court chamber in the


United States capitol to his partner in Baltimore officially opened the completed line on May 24, 1844. Morse


allowed Annie Ellsworth, the young daughter of a friend, to choose the words of the message and she selected


a verse from Numbers XXIII, 23: "What hath God wrought?" to be recorded onto paper tape. Morse's early


system produced a paper copy with raised dots and dashes, which were translated later by an operator.



The Telegraph Spreads



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. Dispatching trains


by telegraph started in 1851, the same year Western Union began business. Western Union built its first


transcontinental telegraph line in 1861, mainly along railroad rights-of-way. In 1881, the Postal Telegraph


System entered the field for economic reasons and later merged with Western Union in 1943.



The original Morse telegraph printed code on tape. However, in the United States, the operation developed into


a process in which messages were sent by key and received 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 1900, Canadian Fredrick Creed invented the Creed Telegraph System, a way to convert Morse code to text.
