Lighthouse Keeper toby jug produced by Kildare of England circa 1950. A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. The sliver of a moon forms the handle of the jug.
