Like many other towns, this one went through name changes before its incorporation in 1781: "Saville" in 1768, "Corey's Town", and then "Wendell", for one of the Masonian Proprietors, John Wendell. The marsh near Sunapee Middle High School still bears Wendell's name. The name "Sunapee" was substituted for "Wendell" by the legislature in 1850. The town, Lake Sunapee and Mount Sunapee share the name which comes from the AlgonquianIndian words "suna" meaning "goose", and "apee", meaning "lake". The Indians called the area "Lake of the Wild Goose" because it is shaped like a goose, with the beak being in Sunapee Harbor. Before Sunapee was a sizable tourist attraction, it was an industrial area. One factory produced 110 clothespins a minute. After the factories faded away, the major attraction became the pristine lake, once surrounded by a number of grand hotels. People used large ferries to get from hotel to hotel around the lake, but the ferries were mostly gone by 1915, when the automobile was widely introduced to the area. Lake Sunapee is the only lake in New Hampshire with three working lighthouses, which were originally built in the 1890s by the Woodsum brothers and are currently maintained by the Lake Sunapee Protective Association.
