Sidney Edwards Morse (brother) Signature. Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) 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.
Morse code. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
Alfred Vail. 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][ a] Vail and Morse were the first two telegraph operators on Morse's first experimental line between ...
American Morse code. 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 ...
Norman Joseph Woodland (September 6, 1921 – December 9, 2012) was an American inventor and engineer, best known as one of the inventors of the barcode, for which he received a patent in October 1952. [1] [2] Later, employed by IBM, he developed the format which became the ubiquitous Universal Product Code (UPC) of product labeling and check ...
Signal lamp. A signal lamp (sometimes called an Aldis lamp or a Morse lamp[ 1]) is a visual signaling device for optical communication by flashes of a lamp, typically using Morse code. The idea of flashing dots and dashes from a lantern was first put into practice by Captain Philip Howard Colomb, of the Royal Navy, in 1867.
Their initial results, a system of lines and circles based on Morse code, was replaced with a bulls eye pattern so it could be scanned from any direction. Silver and Woodland filed a patent for their system on October 20, 1949. U.S. patent 2,612,994 was granted on October 7, 1952. "The two men eventually sold their patent to Philco for $15,000 ...
The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1952. [1] The invention was based on Morse code [2] that was extended to thin and thick bars. However, it took over twenty years before this invention became commercially successful.
