Caption

Cooke and Wheatstone telegraph. British inventors William Fothergill Cooke (1806-1879) and Charles Wheatstone (1802-1875). Letters from this grid of 20 were signalled with five needles (across centre). Here, two needles are tilted by the magnetic effect of the electric current, pointing to the letter 'V'. Six letters (C, J, Q, U, X and Z) were omitted from the grid. Artwork from an 1873 edition of a German book on the application of electromagnetism to the new technology of telegraphy.
