History

The initial request of a light at this site was made in 1897, but construction was delayed until 1901 after the Variety Iron Works Company failed to deliver materials in time. Unlike earlier caisson lights in the bay, the foundation was placed using the pneumatic process, in which the caisson is kept under pressure to expel water, and the interior is excavated to bring the cylinder down to the desired depth.[2]

The tower is taller than other Maryland sparkplug lights because of the provision for a watch room as well as a lantern atop the tower, the only example in the state. A fog bell was originally housed on the lower gallery but was later moved to the watch room level, a backup to the fog horn added in the 1930s. The characteristic was changed several times through the years, with different patterns of flashes and eclipses.[5]

Along with many other Chesapeake Bay lights, automation came in the early 1960s. In 1976 the original fourth-order Fresnel lens was stolen, and it was replaced with a solar-power lamp.[2]

The lighthouse was added to the National Register of Historic Places on December 2, 2002 as Hooper Island Light Station. The structure was officially turned over to the U.S. Lighthouse Society in June 2009, but the light remains active.[1]

gollark: All the I/O stuff in CC is provided to user code via a bunch of tables of functions like `fs` in the global scope.
gollark: Specifically², function environments mostly.
gollark: Process management stuff got enhanced isolation after a spate of bugs relating to that, so it's *probably* okay now, but there are still problems, inevitably.
gollark: Also, some stuff was deliberately not isolated to the extent it should have been for security - mostly the process management, but possibly some filesystem IO.
gollark: Specifically, it relies on quirkiness in some aspects of Lua to work, but the quirks have more nested quirks attached which have problems.
