Alfred Lewis Vail (September 25, 1807 – January 18, 1859) was an American machinist and inventor. Along with Samuel Morse, Vail was central in developing and commercializing American telegraphy between 1837 and 1844. [1]


Vail and Morse were the first two telegraph operators on Morse's first experimental line between Washington, D.C., and Baltimore, and Vail took charge of building and managing several early telegraph lines between 1845 and 1848. He was also responsible for several technical innovations of Morse's system, particularly the sending key and improved recording registers and relay magnets. Vail left the telegraph industry in 1848 because he believed that the managers of Morse's lines did not fully value his contributions.

His last assignment, superintendent of the Washington and New Orleans Telegraph Company, paid him only $900 a year, leading Vail to write to Morse, "I have made up my mind to leave the Telegraph to take care of itself, since it cannot take care of me. I shall, in a few months, leave Washington for New Jersey, ... and bid adieu to the subject of the Telegraph for some more profitable business." [2]


Vail's parents were Bethiah Youngs (1778–1847) and Stephen Vail (1780–1864). Vail was born in Morristown, New Jersey, where his father was an entrepreneur and industrialist who built the Speedwell Ironworks into one of the most innovative iron works of its time. [3] Their son and Alfred's brother was George Vail, a noted politician.

Alfred attended public schools before taking a job as a machinist at the iron works. He enrolled in New York University to study theology in 1832, where he was an active and successful student and a member of the Eucleian Society, graduating in 1836. [1] Visiting his alma mater on September 2, 1837, he happened to witness one of Samuel F. B. Morse's early telegraph experiments. He became fascinated by the technology and negotiated an arrangement with Morse to develop the technology at Speedwell Ironworks at his own expense in return for 25% of the proceeds. Alfred split his share with his brother George Vail. When Morse took on Francis O. J. Smith, a congressman from Maine, as a partner, he reduced the Vails' share to one-eighth. Morse retained patent rights to everything Vail developed.

After having secured his father's financial backing, Vail refined Morse's crude prototype to make it suitable for public demonstration and commercial operation. The first successful completion of a transmission with this system was at the Speedwell Iron Works on January 6, 1838, across two miles (3 km) of wiring. The message read "A patient waiter is no loser." Over the next few months Morse and Vail demonstrated the telegraph to Philadelphia's Franklin Institute, members of Congress, and President Martin Van Buren and his cabinet. Demonstrations such as these were crucial to Morse's obtaining a Congressional appropriation of $30,000 to build his first line in 1844 from Washington to Baltimore.

Vail retired from the telegraph operations in 1848 and moved back to Morristown. He spent his last ten years conducting genealogical research. Since Vail shared a one-eighth interest in Morse's telegraph patents with his brother George, Vail realized far less financial gain from his work on the telegraph than Morse and others.

His papers and equipment were subsequently donated by his son Stephen to the Smithsonian Institution and New Jersey Historical Society.

Vail's cousin was Theodore N. Vail, who became the first president of American Telephone & Telegraph.

Morse code

Alfred Vail and Samuel Morse collaborated in the invention of Morse code. A controversy exists over the role of each in the invention. The argument for Vail being the original inventor is laid out by several scholars. [4] [5] [6] [7]

The argument offered by supporters of Morse claims that Morse originally devised a cipher code similar to that used in existing semaphore line telegraphs, by which words were assigned three- or four-digit numbers and entered into a codebook. The sending operator converted words to these number groups and the receiving operator converted them back to words using this codebook.

Morse spent several months compiling this code dictionary. It is said by Morse supporters that Vail, in public and private writings, never claimed the code for himself. According to one researcher, in a February 1838 letter to his father, Judge Stephen Vail, Alfred wrote, "Professor Morse has invented a new plan of an alphabet, and has thrown aside the Dictionaries." [8] In an 1845 book Vail wrote describing Morse's telegraph, he also attributed the code to Morse. [9]


A US Army base was named in his honor. Camp Vail in Eatontown, New Jersey, later renamed Fort Monmouth, was an Army housing complex. After World War II the families of servicemen and civilian Army employees negotiated with the Army to purchase the development, which was later named Alfred Vail Mutual Association, and due to the work of the Town Clerk the residents retained the rights to the original Charter of Shrewsbury Township Est. 1693. This housing development exists to this day under that name. An elementary school near the Speedwell Works, in Morristown, New Jersey, is named "Alfred Vail."

Electrical telegraph Early system for transmitting text over wires

An electrical telegraph is a point-to-point text messaging system, primarily used from the 1840s until the mid 20th century when it was slowly replaced by other telecommunication systems. It used coded pulses of electric current through dedicated wires to transmit information over long distances. It was the first electrical telecommunications system, the most widely used of a number of early messaging systems called telegraphs, devised to send text messages more rapidly than written messages could be sent. This system allowed for communication to occur without the necessity of physical transportation. Prior to the electric telegraph, semaphore systems were used, including beacons, smoke signals, flag semaphore, and optical telegraphs for visual signals to communicate over distances of land.

Morse code Transmission of language with brief pulses

Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes. Morse code is named after Samuel Morse, an inventor of the telegraph.

Samuel Morse American inventor and painter (1791–1872)

Samuel Finley Breese Morse was an American inventor and painter. After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs. He was a co-developer of Morse code and helped to develop the commercial use of telegraphy.

Telegraphy Long distance transmission of text without the physical exchange of an object

Telegraphy is the long-distance transmission of textual messages where the sender uses a semaphore system, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs.

Wireless telegraphy Method of communication

Wireless telegraphy or radiotelegraphy is transmission of telegraph signals by radio waves. Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires, such as electromagnetic induction, and ground conduction telegraph systems.

Morristown, New Jersey Town in Morris County, New Jersey, United States

Morristown is a town and the county seat of Morris County, New Jersey, United States. Morristown has been called "the military capital of the American Revolution" because of its strategic role in the war for independence from Great Britain. Today this history is visible in a variety of locations throughout the town that collectively make up Morristown National Historical Park.

A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the alphabet, a numeral, or some other character. In codes intended for machines rather than humans, code points for control characters, such as carriage return, are required to control the operation of the mechanism. Each code point is made up of a number of elements arranged in a unique way for that character. There are usually two types of element, but more element types were employed in some codes not intended for machines. For instance, American Morse code had about five elements, rather than the two of International Morse Code.

American Morse code Morse code variant used on landline telegraph systems in the U.S.

American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph. The "American" qualifier was added because, after most of the rest of the world adopted "International Morse Code," the companies that continued to use the original Morse Code were mainly located in the United States. American Morse is now nearly extinct—it is most frequently seen in American railroad museums and American Civil War reenactments—and "Morse Code" today virtually always means the International Morse which supplanted American Morse.
