Cromwell Fleetwood Varley
Cromwell Fleetwood Varley (born April 6, 1828 in Kentish Town, London , † September 2, 1883 in Bexleyheath , southern England) was a British electrical engineer.
He was the second of ten children of the painter Cornelius Varley . One brother was Samuel Alfred Varley (1832-1921).
In 1846 he went to the newly founded Electric Telegraph Company , where he became chief engineer for the London area in 1852 and company director in 1861.
He dealt with the transmission of electrical messages and in 1854 invented double-current encryption and a suitable double-current relay (see telegraph relay ).
After the first transatlantic cable broke in 1858, he became a member of the committee of inquiry. To compensate for the self-induction in submarine cables, he proposed capacitors, which was implemented in the transatlantic cable laid in 1866. Here he replaced Wildman Whitehouse as chief electrician of the cable company.
When he returned from this expedition, his wife Ellen (née Rouse) had left him in favor of Ion Perdicari and the marriage was divorced in 1873. Four years later he married Heleanor Jessie.
He gained fame with the Varley bridge circuit for fault location determination in deep-sea cables.
In 1870 he invented the cymaph , a telegraph that could transmit speech.
He partnered with William Thomson, 1st Baron Kelvin and Fleeming Jenkin to market their telegraphic instruments.
