Samuel Alfred Varley
Samuel Alfred Varley (* 1832 ; † August 4, 1921 ) was an English electrical engineer.
His father was Cornelius Varley and his brother Cromwell Fleetwood Varley .
In 1850 he left his father's company and started working for the Electric Telegraph Company in 1852 . In 1853 he was appointed engineer and entrusted with the Telegraph District of Liverpool.
He was one of the first telegraph operators in the war and oversaw the laying of what was then the longest undersea cable in the Crimea from the Bulgarian Varna on the Black Sea to Constantinople .
In 1859 he returned to London and published a treatise on artificial conduit that became the basis for the duplex process. The engineers found this unnatural and they called it the Phantom Circle, or Phantom for short . Karl Marx called it specter ( specter ).
In 1866, around the same time as Werner von Siemens, he worked on the dynamo principle and built a self-exciting machine.
