Royal Earl House (9 September 1814 –25 February 1895) was the inventor of the first printing telegraph, which is now kept in the Smithsonian Institution. His nephew Henry Alonzo House is also a noted early American inventor.
The printing telegraph was invented by Royal Earl House in 1846. House's equipment could transmit around 40 instantly readable words per minute, but was difficult to manufacture in bulk. The printer could copy and print out up to 2,000 words per hour. This invention was first put in operation and exhibited at the Mechanics Institute in New York in 1844.
The Smithsonian Institution, established on August 10, 1846 "for the increase and diffusion of knowledge," is a group of museums and research centers administered by the Government of the United States. The institution is named after its founding donor, British scientist James Smithson. Originally organized as the "United States National Museum," that name ceased to exist as an administrative entity in 1967.
Henry Alonzo House was an American inventor who developed machinery and processes that have had a lasting impact on several industries.
Royal Earl House spent his childhood in Vermont experimenting, designing, and building, a habit which would earn him distinction as an adult. He once caught a toad, skinned it, placed a set of springs in the skin and made it hop. Around 1840, he went to Buffalo, New York to live with relatives and attend law school in that town. However, he read a work on electricity which so inspired him that he decided to give up law and study the science of electricity instead. He was also interested in mechanics, chemistry and magnetism.
Vermont is a state in the New England region of the northeastern United States. It borders the U.S. states of Massachusetts to the south, New Hampshire to the east, New York to the west, and the Canadian province of Quebec to the north. Vermont is the second-smallest by population and the sixth-smallest by area of the 50 U.S. states. The state capital is Montpelier, the least populous state capital in the United States. The most populous city, Burlington, is the least populous city to be the most populous city in a state. As of 2015, Vermont was the leading producer of maple syrup in the United States. It was ranked as the safest state in the country in 2016.
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands.
Buffalo is the second largest city in the U.S. state of New York and the largest city in Western New York. As of July 2016, the population was 256,902. The city is the county seat of Erie County and a major gateway for commerce and travel across the Canada–United States border, forming part of the bi-national Buffalo Niagara Region.
By 1846, the Morse telegraph service was operational between Washington, DC, and New York. Royal Earl House patented [1] his printing telegraph that same year. He linked two 28-key piano-style keyboards by wire. Each piano key represented a letter of the alphabet and when pressed caused the corresponding letter to print at the receiving end. A "shift" key gave each main key two optional values. A 56-character typewheel at the sending end was synchronised to coincide with a similar wheel at the receiving end. If the key corresponding to a particular character was pressed at the home station, it actuated the typewheel at the distant station just as the same character moved into the printing position, in a way similar to the daisy wheel printer. It was thus an example of a synchronous data transmission system. House's equipment could transmit around 40 instantly readable words per minute, but was difficult to manufacture in bulk. The printer could copy and print out up to 2,000 words per hour. This invention was first put in operation and exhibited at the Mechanics Institute in New York in 1844.
Telegraphy is the long-distance transmission of textual or symbolic messages without the physical exchange of an object bearing the message. Thus semaphore is a method of telegraphy, whereas pigeon post is not.
In 1886 and 1887, when the Royal E. House telegraph company was producing the printing telegraph, the Morse Telegraph company tried to enjoin (legally prevent) them from infringing on the Morse patents. Morse claimed the sole right of transmitting intelligence by electricity, utilizing the Morse code. The courts decided the House Company did not infringe the Morse patent, as the messages using the House system were all printed on a slip of paper, without the use of Morse Code.
Morse code is a character encoding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called dots and dashes or dits and dahs. Morse code is named for Samuel F. B. Morse, an inventor of the telegraph.
Later the House Co. and the Morse Co. joined and formed the Great Western Telegraph Company.
The Baudot code[bodo], invented by Émile Baudot, is a character set predating EBCDIC and ASCII. It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the teleprinter code in use until the advent of ASCII. Each character in the alphabet is represented by a series of five bits, sent over a communication channel such as a telegraph wire or a radio signal. The symbol rate measurement is known as baud, and is derived from the same name.
An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via dedicated telecommunication circuit or radio.
Jean-Maurice-Émile Baudot, French telegraph engineer and inventor of the first means of digital communication Baudot code, was one of the pioneers of telecommunications. He invented a multiplexed printing telegraph system that used his code and allowed multiple transmissions over a single line. The baud unit was named after him.
Samuel Finley Breese Morse, OIC was an American painter and inventor. 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 the Morse code and helped to develop the commercial use of telegraphy.
A teleprinter is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially they were used in telegraphy, which developed in the late 1830s and 1840s as the first use of electrical engineering. The machines were adapted to provide a user interface to early mainframe computers and minicomputers, sending typed data to the computer and printing the response. Some models could also be used to create punched tape for data storage and to read back such tape for local printing or transmission.
Wireless telegraphy means transmission of telegraph signals by radio waves; a more specific term for this is radiotelegraphy. Before about 1910 when radio became dominant, the term wireless telegraphy was also used for various other experimental technologies for transmitting telegraph signals without wires, such as electromagnetic induction, and ground conduction telegraph systems.
Sir Charles Wheatstone FRS, was an English scientist and inventor of many scientific breakthroughs of the Victorian era, including the English concertina, the stereoscope, and the Playfair cipher. However, Wheatstone is best known for his contributions in the development of the Wheatstone bridge, originally invented by Samuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development of telegraphy.
Alfred Lewis Vail was an American machinist and inventor. Along with Samuel Morse, Vail was central in developing and commercializing American telegraphy between 1837 and 1844.
Ticker tape was the earliest digital electronic communications medium, transmitting stock price information over telegraph lines, in use between around 1870 through 1970. It consisted of a paper strip that ran through a machine called a stock ticker, which printed abbreviated company names as alphabetic symbols followed by numeric stock transaction price and volume information. The term "ticker" came from the sound made by the machine as it printed.
Alexander Bain was a Scottish inventor and engineer who was first to invent and patent the electric clock. He installed the railway telegraph lines between Edinburgh and Glasgow.
Frederick George Creed was a Canadian-born inventor, who spent most of his adult life in Britain. He worked in the field of telecommunications, and is particularly remembered as a key figure in the development of the teleprinter. He also played an early role in the development of SWATH vessels.
The Teletype Corporation, a part of American Telephone and Telegraph Company's Western Electric manufacturing arm since 1930, came into being in 1928 when the Morkrum-Kleinschmidt Company changed its name to the name of its trademark equipment. Teletype Corporation, of Skokie, Illinois, was responsible for the research, development and manufacture of data and record communications equipment, but it is primarily remembered for the manufacture of electromechanical teleprinters.
Procedure signs or prosigns are shorthand signals used in radio telegraphy procedures, for the purpose of simplifying and standardizing communications related to radio operating issues among two or more radio operators. They are distinct from general Morse code abbreviations, which consist mainly of brevity codes that convey messages to other parties with greater speed and accuracy.
Edward Ernst Kleinschmidt was one of the inventors of the teleprinter, and was a prolific inventor who obtained 118 patents in the course of his 101-year life.
Harrison Gray Dyar (1805–1875) was an American chemist and inventor.
Charles Grafton Page was an American electrical experimenter and inventor, physician, patent examiner, patent advocate, and professor of chemistry.
The Electro-Magnet, and Mechanics Intelligencer was an 1840 newspaper published by Thomas Davenport, inventor of the electric motor. This newspaper, published in New York City, was the first printed on a press run by electricity. It was the first American periodical devoted to electricity and the world's first electrical technical journal.
