Charles Vincent Walker FRS (20 March 1812 – 24 December 1882) was an English electrical engineer and publisher, a major influence on the development of railway telecommunications, he was also the first person to send a submarine telegraph signal.
Born Marylebone, Middlesex son to Vincent and Ann née Blake, Walker's elementary education and engineering training are uncertain.
[1] Also in 1841, Walker worked on the Manual of Electricity, Magnetism and Meteorology which formed part of Dionysius Lardner's Cabinet Cyclopedia.
[5] Royal Astronomical Society Charles Vincent Walker[6] died at his residence at Tunbridge Wells, on the morning of 24 December 1882, in the seventy-first year of his age.
He was a zealous worker in the science of electricity, and was the inventor of several useful appliances in connection with telegraphy, including the instruments by which the block system on railways is worked.
On 10 May 1849, Mr. Glaisher wrote to Mr. Walker that he wished to talk with the latter about the laying down of a wire from the Observatory to the Lewisham Station, and on 23 May following, the Astronomer Royal gave Mr. Walker a brief sketch of the use to be made of the wire referred to, his scheme, as he stated, being " the transmission of time by galvanic signal to every part of the kingdom in which there is a galvanic telegraph from London."
It was proposed to lay four wires underground from the Royal Observatory to the railway station at Lewisham, and to extend them to London Bridge.
The first time-signal sent from the Royal Observatory was received at London Bridge Station at 4 p.m. on 5 August 1852; and on 9 August 1852, Dover received a time-signal for the first time from the Royal Observatory direct, and it was made visible at certain first-class stations between London and Dover.
