William Sidney Mount was a 19th-century American genre painter. Born in Setauket, New York in 1807, Mount spent much of his life in his hometown and the adjacent village of Stony Brook, where he painted portraits, landscapes, and scenes inspired by daily life from the 1820s until his death in 1868 at the age of sixty. During that time he achieved fame in the U.S. and Europe as a painter who chronicled rural life on Long Island. He was the first native-born American artist to specialize in genre painting. Mount was also passionate about music and a fiddle player, a composer and collector of songs, and designed and patented several versions of his own violin which he named the "Cradle of Harmony." Many of his paintings also feature musicians and groups of people engaged in dance in rural settings.

Stony Brook is a hamlet and census-designated place (CDP) in the Town of Brookhaven in Suffolk County, New York, United States, on the North Shore of Long Island. Begun in the colonial era as an agricultural enclave, the hamlet experienced growth first as a resort town and then to its current state as one of Long Island's major tourist towns and centers of education. Despite being referred to as a village by residents and tourists alike, Stony Brook has never been legally incorporated by the state. The population was 13,740 at the 2010 census.
