Frederick Hale Holmes

North Foreland lighthouse at Broadstairs, Kent about 1880 with modernised light as it was after 1860

Frederick Hale Holmes (born 1812)[1] was a Professor of Chemistry at the Royal Panopticon of Science and Art[2] and pioneer of electric lighting.[3] In 1853 he demonstrated the ability of electro-magnetic generators to provide continuous current to power arc light and in 1856 patented a magneto to power an arc light for lighthouses which he demonstrated to Michael Faraday at Blackwall in 1857.[4][5] His experiments with alternating current arc lighting at North Foreland lighthouse in 1857-60[6] were the subject of a lecture by Michael Faraday at the Royal Institution.[7]

Holmes generator from Souter Lighthouse at Science Museum in London

One of Holmes' generators built in 1867 and used at Souter Lighthouse is displayed at the Science Museum, London.[8]

Some web sources give his date of death as 1875[9] however he was recorded as still living at time of 1881 census in which his occupation was noted as "Patentee of Fog Signals".[10] which is confirmed by his filing of a patent in 1881 (granted 1883 in US) for a "Siren for Signalling"[11]

Reynaud, the Director-General of the French Lighthouses, inspected the light on April 20, 1859; it was visited by most of the members of the Royal Commission of Lights, Buoys, and Beacons, including myself, three days afterwards, and on the same day Professor Faraday wrote a report to the Trinity House. The opinions expressed were so far favourable that the Elder Brethren desired a further trial of six months, during which time the light was to be entirely under their own control, Mr. Holmes not being allowed interfere in any way. The light was again kindled on August 22

Professor Faraday, in a lecture delivered at the Royal Institution, says: "By means of a magnet, and of motion, we can get the some kind of electricity as from the battery; and, under the authority of the Trinity House, Professor Holmes has been occupied in introducing the magneto-electric light in the lighthouse at the North Foreland...For the last six months the North Foreland has been shining by means of this electric light beyond all comparison better than its former light. Never for once during six months has it failed in doing its duty
