embassy in Munich, happened to see von Soemmerring s demonstration and was fascinated by the idea of electronic telecommunications, if not by the implementation (which, in contemporary drawings, looks like a component of NEC s recent Fish Club, a thin bubble tank intended to be placed in front of an HDTV monitor to make it look like an aquarium) Hans Christian Oersted, a Danish physicist, discovered in 1819 that an electrical current passing through a wire could deflect a compass needle That was all Schilling needed In 1825, he created and demonstrated a single-wire telegraph system, utilizing a binary system of compass-needle deflections as the receiver s indicator He went a step beyond Bacon s five-bit alphabetic code, however The letter E is the most common in English It is quite wasteful to transmit an E with the same number of bits as a Q or X Schilling, therefore, used (and may well have invented) a new form of coding, one in which the most common letters used the fewest bits and the least common the most (think of the letter values on Scrabble tiles) Today, we refer to that form of data-rate compression as variable-wordlength coding; then it was just Schilling s telegraph code (the later Morse Code is a minor variation) Schilling died in 1837, but not before influencing Professors Carl Friederich Gauss and Wilhelm Weber, as well as William Cooke (who became a partner of Charles Wheatstone in a successful telegraph business) and Gustav Fechner Cooke and Wheatstone received a patent for their telegraph system even before Morse s 1837 successful experiment (see the sidebar, What Hath Who Wrought ), and one of their telegraphs was instrumental in capturing a criminal before Morse s famous first transmission of 1844 (news of a pickpocket escaping by train was wired to the next station, where he was arrested) In fact, telegraphy had spread worldwide long before 1844 By 1839, a telegraph cable was successfully laid by the East India Company underwater across the Hooghly River in Calcutta In 1850, a telegraph cable crossed the English Channel The first transatlantic cable was completed in 1858 but failed roughly two weeks after it went into operation

Ask someone who invented the computer, and you ll probably get a shrug Most people can t name an inventor of television, either No one seems to have a clue as to who invented the magnetic disk drive Almost anyone, however, can easily tell you who invented the telegraph: Morse The same people may have learned in elementary school that Eli Whitney invented the cotton gin, but few remember what a cotton gin is, and there s nothing to associate Whitney s name to it For Morse and the telegraph, there s both Morse Code and the awesome sentence he came up with as the first telegram When President Kennedy initiated telephone service via geosynchronous satellite in 1963, he said, What hath God wrought the exact words transmitted by Morse in 1844 After all, satellites were just the latest way to turn the planet into a global village, a process that began with Morse There are just a few problems with this glorious history: Morse didn t come up with that sentence, it wasn t the first telegraph message, he didn t come up with Morse Code, and he didn t invent the telegraph As for his feelings about the community of humanity, he ran for public office (and lost) as a candidate of the Native American party, an antiimmigrant, anti-Catholic organization Morse was a good artist, regarded highly enough to make a living and to be appointed a professor at the University of the City of New York (now NYU) He also founded the National Academy of Design and served as its first president for 16 years His credentials were strong enough that he was able to successfully petition Congress for funding to develop telegraphy, an idea he d heard about When Annie Ellsworth, daughter of the US Commissioner of Patents, brought him the news that President Tyler signed a bill granting Morse $30,000 (a precursor of more recent government grants for the development of advanced television), he offered her the
