The first European settler was John Seren who came from Connecticut in 1644. Later, Townsend Albertson started a farm and gristmill and the community eventually became known as Albertson, after him.
In 1850, a road was built through Albertson on the lands of Isaac Underhill Willets. The road is still known as I.U. Willets Road. (Willets complained that Long Island has more roads than it would ever need). The Long Island Rail Road opened an Albertson train station in 1864.
