Communication
Joseph Henry develops the basic principles of the modern telegraph, put into more practical form 11 years later by Samuel Finley Breese Morse [b. Charlestown, Massachusetts, April 27, 1791, d. New York City, April 2, 1872], such as the electric relay and the use of Earth as a ground. The electrical relay enables a current to travel long distances from its origin. See also 1833 Communication; 1836 Communication.
During the summer William Fox Talbot begins to use his new invention of photography to take experimental pictures of his home at Lacock Abbey. See also 1834 Communication.
