Michael Faraday and the First Electric-Powered Lighthouse, Dover - 165 Years Ago

Exactly 165 years ago today, on 20 February 1860, Michael Faraday wrote a letter to the Trinity House by Board regarding his visit to the magneto-electric light at South Foreland, Dover. At the time, Faraday was serving as the Scientific Advisor to the lighthouse authority.

In the letter, he initially describes how heavy snowfall prevented him from reaching the lighthouse, forcing him to return to London and attempt the journey again the following day. He then details some minor operational issues (interruptions from iron in the carbons) and how the attendant successfully maintained steady operation.

He continues:

"I found the two engines in the machine-room, along with both the steam-engines and the magneto-electric machines, properly at work. The latter had not become deranged or given way at any point, and the magnets appeared by the results to be as powerful as ever. The water condensers and other parts acted properly, and as they were required. Though I was not at the lighthouse on Monday night, yet I could see from Dover that the light was at that time in its proper, and regular condition."

I came across this letter today during my morning rereading The Correspondence of Michael Faraday – Volume 5, published by the IET, and once again found myself captivated by the words of one of the founding figures of Electrical Engineering. It never ceases to amaze me how this brilliant scientist and engineer conducted himself—with meticulous care, dedication, and intellectual integrity.

Despite being one of the greatest scientists of his time, he remained remarkably unpretentious and avoided seeking wealth, titles, or high social status. Quite different from the attitude of some today. His legacy continues to teach and inspire us all.
