1775The Smalls Rock Lighthouse—the most remote operated by Trinity House—is the first lighthouse to be built on oak pillars, or “piles.” Some years later its designer, Henry Whiteside, was rescued from Smalls Rock after sending a message in a bottle asking for help.

1781Swiss physicist Francois-Pierre-Ami Argand invents a new way to illuminate lighthouses. The Argand Lamp burned 5–10 times brighter than traditional candles, and was cleaner and cheaper to operate. Image Author: Public Domain. PD-US |

1812Congress purchases the patent for the Argand Lamp. By depending on this technology for several decades, the United States falls far behind in lighthouse technology. Portrait of James Peale by Charles Willson Peale (1748-1827)

1820The first U.S. lightship, a small wooden schooner, anchors off the coast of Virginia in Chesapeake Bay. Three years later, the first U.S. lightship in unprotected waters anchored in the Atlantic Ocean off Sandy hook. Lightships provided a beacon in places where soft or muddy bottoms could not support traditional lighthouse construction. For more information on Lightships in the U.S., see below.

1821France‘s Commissioner of Lighthouses Augustin Fresnel introduces his groundbreaking Fresnel lens. His experiments in the science of wave optics enabled him to create a lens that replaced mirrors in lighthouses. For more information on Augustin Fresnel, see below. Image Author: Public Domain. |

1823The first Fresnel lens is installed in the Cordouan Lighthouse in France. For more information on the Cordouan Lighthouse click HERE. For more information on the Fresnel Lens, see below.

1828The Twin Lights are constructed from split bluestone atop the Navesink Highlands. The Twin Lights were designed by Connecticut architect Charles H. Smith, who was instructed to “well and faithfully construct, erect, build, and in every respect completely finish two lighthouses and a dwelling house...on the Highlands of Navesink.” The towers—approximately 40 feet in height—will stand for 34 years before being replaced by the current structure.

1838The Maplin Sands Lighthouse, built at the mouth of England’s Thames River, is the first screw-pile lighthouse. The screw-pile construction system, invented in 1830 by a blind Irish engineer named Alexander Mitchell, enabled lighthouses to be built on the bottoms of lakes, rivers and other large bodies of water. In many instances, screw-pile lighthouses replaced light ships. For more information on screw-pile lighthouse construction see below. Image Author: Public Domain. |

1841A pair of Fresnel lenses—the first ever in the United States—are installed at the Twin Lights. Three years earlier, Commodore Matthew Perry was dispatched by Congress to study European lighthouses. The Fresnel lenses were the result of that voyage. For more information on Commodore Perry see below. Image Author: Mathew Brady (1823–1896). Public Domain. |

1852Congress receives a report on the nation’s lighthouses that is highly critical. The Twin Lights—in desperate need of repair—is actually singled out as the best in the nation. The result of this report is the formation of the U.S. Lighthouse Board. One of their first acts is to order a rebuilding of the Navesink Light Station. |

1862The first lighthouses are illuminated using electricity, thanks to the steam-powered magneto-electric generator, perfected in 1853 by British scientist F.H. Holmes. This generator made it possible to use powerful electric arc lamps in lighthouses where the standard oil lamps were deemed inadequate. The generators needed to create this high voltage weighed several tons. For more information on the magento-electric generator see below. Image Author: Public Domain. |

1885The Trotter-Lindberg petroleum spirit light, invented in Sweden, is in use on both sides of the Atlantic. The automated light does not require daily attention by a keeper. The Trotter-Lindberg system used petroleum spirit or lythene—contained in cisterns placed outside the lantern—which were refilled every week or two. |

1886An arc light is installed in the Statue of Liberty, making it the first U.S. “lighthouse” illuminated in this manner. For more information on the Statue of Liberty see below. Image Author: Elcobbola. This file is licensed under the Creative Commons Attribution-Share Alike 3.0 Unported. |
