Thomson, William, first Baron Kelvin. Letter signed to Latimer Clark. Glasgow, April 16, 1877. 1 page. 180 x 121 mm. Remains of mounting present. Provenance: Latimer Clark.
From the Scottish physicist William Thomson (later Lord Kelvin) to Latimer Clark, an electrical engineer specializing in telegraphic systems. Clark made a number of important investigations in electrical science, leading to his proof that the speed of a current pulse is independent of the voltage applied, and to his demonstration, later expanded upon by Faraday, that the retardation effect in telegraphic cables is due to induction. Thomson was also interested in telegraphy, particulary submarine telegraphy, and became involved in Cyrus Field's Atlantic cable enterprise in late 1856 or early 1857, when he was named to the board of directors of the Atlantic Telegraph Company. Thomson, who "saw telegraphy as an integral part of mathematical physics" (Smith and Wise 1989, 666), took a scientific approach to the design and construction of long-distance submarine cables and signaling equipment, applying theoretical principles he had learned through his studies of electrical phenomena.
Thomson's letter to Clark discusses a proposed memorial for the widow of the Reverend Henry Highton. Origins of Cyberspace 206.
