Until 1846, Lakeville was called "Furnace Village", due to the location there of one of the early
blast furnaces of the historic Salisbury
iron industry (one of which was established in the 1760s by future Revolutionary War hero
Ethan Allen.
Benjamin B. Hotchkiss, inventor of the
Hotchkiss gun, was born in nearby
Watertown. A boarding school in his name, the
Hotchkiss School, was founded by his widow
Maria Bissell Hotchkiss in Lakeville in 1891. It later became
coeducational. The
Indian Mountain School, a boarding school for students Pre-K through 9th, is south of the Lakeville CDP. It was founded in 1922. Lakeville was the original home to what eventually relocated and became the
Mansfield Training School, an institution for intellectually challenged residents of Connecticut from 1860 to 1993.
Other notable events Lakeville is the site of Connecticut's oldest
cold case. Camp Sloane camper
Connie Smith left the camp on Indian Mountain Road on the morning of July 16, 1952. She was ten years old and from
Sundance, Wyoming; she was the granddaughter of former
Wyoming Governor Nels H. Smith. Several people observed Connie walking and hitchhiking toward the center of Lakeville. She was last seen walking along
Route 44 near the intersection of Belgo Road. Connie's disappearance sparked one of the largest searches ever conducted by the Connecticut State Police. She was never found and foul play is suspected. The case remains open and still has a detective assigned to it. ==Local institutions==
