Idawalley Zorada Lewis (later Lewis-Wilson) (February 25, 1842 – October 24, 1911) was an American lighthouse keeper noted for her heroism in rescuing people from the sea. In 1924 the Rhode Island legislature officially changed the name of Lime Rock to Ida Lewis Rock. The lighthouse service changed the name of the Lime Rock Lighthouse to the Ida Lewis Rock Lighthouse—the only such honor ever paid to a keeper in the United States. It is now the home of the Ida Lewis Yacht Club. In 1995 the United States Coast Guard named the first of a new class of buoy tenders for Ida Lewis. The USCGC Ida Lewis (WLM-551), the lead ship of the Keeper-class buoy tender, is currently stationed in Newport, Rhode Island. The folk song "Lighthouse Keeper" by Neptune's Car was inspired by Lewis's experiences.
On July 16, 1881, she was awarded the rare and prestigious Gold Lifesaving Medal from the United States government for her daring rescue on February 4, 1881, of two soldiers from Fort Adams who had fallen through the ice while attempting to return to the fort on foot. Lewis died of a stroke on October 24, 1911, at the age of 69. The bells of all the vessels in Newport Harbor tolled for her that night, and flags were at half staff throughout Newport. More than 1,400 people viewed her body at the Thames Street Methodist Church. Among the crowd that gathered to pay its respects were keepers Charles Schoeneman of Newport Harbor Light, Charles Curtis of Rose Island Light, O. F. Kirby of Gull Rocks Light, and Edward Fogerty of the Brenton Reef lightship. The captain and crew of a local lifesaving station in Newport were also present. Ida Lewis was buried in the Common Burying Ground in a prominent location so her grave can be seen by passers by.
