During the seventeenth and eighteenth centuries, the town of Plymouth, Connecticut--formerly known as Northbury--was settled only by scattered groups of Indians and hearty newcomers from Europe. As time went on, however, the Town of Plymouth developed into an industrial community composed of nine organized districts: Plymouth, Greystone, Allentown, the Lakes, Pequabuck, Terryville, East Plymouth, and the Holt District. Residents of Plymouth were industrious and inventive from the very beginning. In 1793 Eli Terry founded the clock-making business that became the foremost enterprise in the town's history, and in 1854 the expansion of the Eagle Lock Company fostered the development of Terryville. During the course of the nineteenth century, a plethora of smaller companies developed along the town's many waterways, manufacturing everything from furniture to toys, plows, and hats. Plymouth, Connecticut chronicles the development of the town through the years with a remarkable series of vintage images and informative text.

Incorporated in 1795, Plymouth is known for its industrialists and innovations. A. Terry & Company was a pioneer in the industry of malleable iron, and Eli Terry was instrumental in the creation of interchangeable parts leading to mass production. Cooper Oven Thermometer designed and created the first baking thermometers in the United States. Plymouth is also home to two sections of historic importance listed on the National Register of Historic Places: Plymouth Center, known as the initial center of town with locations on the Underground Railroad, and East Church, where a small group of Tories lived during the Revolutionary War.
