Telegraph

Original Samuel Morse telegraph on the sea voyage home in 1832, Morse encountered Charles Thomas Jackson of Boston who was well schooled in electromagnetism. Witnessing various experiments with Jackson's electromagnet, Morse developed the concept of a single wire telegraph, and The Gallery of the Louvre was set aside. The original Morse telegraph, submitted with his patent application, is part of the collections of the National Museum of American History at the Smithsonian Institution.[4] In time the Morse code would become the primary language of telegraphy in the world, and is still the standard for rhythmic transmission of data.
