History
The name Cutchogue is derived from an Algonquin word meaning "principal place". Many of the local Native Americans lived at Fort Corchaug before English-American settlers began arriving in 1640. The Old House, built ca. 1699, is the oldest English-style house in the village. In fact, it is one of the best surviving examples of English domestic architecture in the United States, and it has been named a National Historic Landmark. Famous 18th century residents include political figureParker Wickham and his nephew John Wickham. Cutchogue is also the birthplace of composer Douglas Moore. Hargrave Vineyard, the first winery on Long Island, was established in Cutchogue in 1973. The Long Island Merlot Alliance, which promotes wine-making using the merlot grape, the principal Long Island grape, is based in Cutchogue.

An avid sailor, Albert Einstein once called Little Peconic Bay in Cutchogue "the most beautiful sailing ground I ever experienced." In the summers of 1938 and 1939 he rented a cottage on Old Cove Road, now called West Cove Road, on Nassau Point, and spent many hours alone in a little sailboat he called Tineff. Albert Einstein was taught to sail on Little Peconic Bay by two local brothers, Jack and Bob Fisher, who had a lot of patience getting him to become a successful yachtsman. While in Cutchogue on August 2, 1939, pipe-smoking Einstein was visited by fellow Jewish physicists from Hungary Leó Szilárd and Edward Teller, and dictated the famous Letter to President Roosevelt, alerting him to the new developments in nuclear physics and hinting that the Germans might be working on an atomic bomb, urging him to launch his own program. The letter is widely credited with setting in motion the Manhattan Project, the US government effort that built the first atomic bomb. When Szilárd first explained the concept of a nuclear chain reaction to him, Einstein gave the famous reply, "Daran habe ich gar nicht gedacht!".
