in England by Sir William F. Cooke, an American inventor, and Professor Sir Charles Wheatstone (1802-1875) a British physicist and inventor who was best known for his work in electricity. Charles Wheatstone was born in Gloucester; he was apprenticed in 1816 to his uncle who was a musical-instrument maker in London.

¡§In 1823 he inherited the business, and in 1829 he invented the concertina. Wheatestone was self-educated in science and in 1834 he was appointed Professor of Experimental Philosophy at the University of London, and in 1837, with the electrical engineer Sir William Fothergill Cooke, he patented the first British electric telegraph.
The electrical instrument known as the Wheatstone bridge, although invented by Samuel Hunter Christie, bears his name because he was the first to apply it for measuring resistance in electric circuits. Wheatstone also invented (1838) the stereoscope. He was knighted in 1868¡¨ (1)

Samuel Morse improved the telegraph in 1840. His system incorporated a buzzer and messages were sent as a code of long and short buzzes. This method was later called Morse code.





Morse code


Samuel Finley Breese Morse (1791-1872). Was born in Charlestown, Massachusetts, United States. Morse was a trained portrait painter and was also a keen inventor.

¡§In 1832 he conceived the idea of a magnetic telegraph using a single wire system, which he exhibited to Congress in 1837. Morse created a dot and dash code for sending messages which used different numbers representing the letters in the English alphabet and the ten digits, and became known as Morse code. In 1844 an experimental telegraph line was completed between Washington and Baltimore and Morse sent the first historical message: 'What hath God wrought¡¨ (2)

The Morse telegraph and workable code was first demonstrated in 1844 when a message comprising of a series of short or long dashes (dots and dashes) were recorded onto a mov...
