Josiah Latimer Clark, English electrical engineer, born in Great Marlow, Buckinghamshire. His first interest was in chemical manufacturing, but in 1848 he became assistant engineer at the Menai Straits bridge under his elder brother Edwin (1814-1894), the inventor of the Clark hydraulic lift graving dock. Two years later, when his brother was appointed engineer to the Electric Telegraph Company, he again acted as his assistant, and subsequently succeeded him as chief engineer.

  • Josiah Latimer Clark, English electrical engineer, born in Great Marlow, Buckinghamshire. His first interest was in chemical manufacturing, but in 1848 he became assistant engineer at the Menai Straits bridge under his elder brother Edwin (1814-1894), the inventor of the Clark hydraulic lift graving dock. Two years later, when his brother was appointed engineer to the Electric Telegraph Company, he again acted as his assistant, and subsequently succeeded him as chief engineer. In 1854 he took out a patent "for conveying letters or parcels between places by the pressure of air and vacuum," and later was concerned in the construction of a large pneumatic despatch tube between the general post office and Euston station, London. About the same period he was engaged in experimental researches on the propagation of the electric current in submarine cables, on which he published a pamphlet in 1855, and in 1859 he was a member of the committee which was appointed by the government to consider the numerous failures of submarine cable enterprises. Latimer Clark paid much attention to the subject of electrical measurement, and besides designing various improvements in method and apparatus and inventing the Clark standard cell, he took a leading part in the movement for the systematization of electrical standards, which was inaugurated by the paper which he and Sir CT Bright read on the question before the British Association in 1861. With Bright also he devised improvements in the insulation of submarine cables. In the later part of his life he was a member of several firms engaged in laying submarine cables, in manufacturing electrical appliances, and in hydraulic engineering. Clark died in London on the 30th of October 1898. Besides professional papers, he published an Elementary Treatise on Electrical Measurement (1868), together with two books on astronomical subjects, and a memoir of Sir W. F. Cooke.
  • Josiah Latimer Clark war ein englischer Ingenieur. Der Schwerpunkt seiner Arbeiten lag im Brückenbau und Telegraphenwesen. Er begann als Assistent seines Bruders Edwin (1814-1894) beim Bau der Menai-Straits-Brücke. Clark untersuchte die Signalverzögerung in Unterseekabeln, er gehörte 1854 zu den Erfindern der Rohrpost und erfand 1874 ein Normalelement. Clark bemühte sich um Vereinheitlichung elektrischer Einheiten. Er führte die Einheiten Volt, Ohm, Watt und Farad ein.
  • Josiah Latimer Clark was een Engels elektrotechnicus en uitvinder. Hij was met name betrokken bij de ontwikkeling van de telegrafie, en in speciaal, bij de trans-Atlantische telegraafkabel.
  • Латимер Кларк — английский инженер. В 1850 Кларк поступил на службу электротелеграфной компании, где состоял до 1870. Его опыты над подземными телеграфными проводами в 1853 были изданы в правительственном отчете о кабелях. В 1860 он принимал участие в комитете для исследования вопроса о подводных телеграфах, издавшем через некоторое время весьма ценный доклад по этому вопросу. В следующем году Кларк перед Британским обществом читал доклад «On the Principles to be Observed in Forming Standards of Electric Measurements», в котором предлагал принять вошедшие потом в общее использование обозначения электрических единиц: ом, фарад и вольт. В 1871 Кларк, вместе с Робертом Sabine, опубликовал: «Electrical Tables and Formula for Operators in Submarine Cables», в 1873 — доклад «A Single Cell Battery as a Standard of Electro Motive Force», читанный перед Королевским обществом.
