Lake Success is a village and a capital of the Great Neck School District in Nassau County, New York in the United States. The population was 2,934 at the 2010 census.
Lake Success is in the Town of North Hempstead on northwest Long Island. Lake Success was the temporary home of the United Nations from 1946 to 1951, occupying the headquarters of the Sperry Gyroscope Company on Marcus Avenue. It was the home of Canon U.S.A., Inc. Canon U.S.A. has since moved (as of late 2013) its corporate headquarters to Melville, New York (in neighboring Suffolk County).
Lake Success derives its name from a kettle lake of the same name which according to village lore had a Native American name of "Sucut." William K. Vanderbilt II bought land around the lake in the early 20th century for a home. The village was incorporated in 1926.
In 1939, the United States government bought a large tract between Marcus Avenue, Lakeville Road and Union Turnpike, to be the home to the Sperry Gyroscope Company which built a variety of maritime, military, aerospace and navigation products. During World War II the plant had 22,000 employees. After the war, part of the plant became the temporary headquarters of the United Nations from 1947 to 1952, while its headquarters building in New York City was being built.
