About New Haven County

English Puritans founded New Haven colony in 1638 and became a county in 1666; county government was abolished in 1960. Initially dependent on agriculture and maritime trade, the economy became industrialized in the 19th century, spurred by the inventions of New Haven residents Eli Whitney, who developed the concept of mass-producing interchangeable parts, and later Charles Goodyear, who created the vulcanization process for rubber.

New Haven is the county’s largest city and the seat of Yale University (founded 1701) and Southern Connecticut State University (founded 1893); from 1701 to 1875 it was co-capital of Connecticut along with Hartford. The Naugatuck River valley supports heavy industry in Ansonia, Naugatuck, and Waterbury, which was once known as “Brass City” because it contained many brass mills. Guilford contains some 400 buildings from the 18th and 19th centuries, as well as the Henry Whitfield House (built 1639), the oldest stone house in New England. Other communities are Meriden, West Haven, Hamden, Milford, and Wallingford. ~Source: Britannica.com
