The Kent Historical Society will present a program with Emery Roth II of Washington Sunday at 2 p.m., as part of its Sunday Series.

Based on Roth’s book “Brass Valley: The Fall of an American Industry,” the author will discuss the legendary history of the Naugatuck River Valley’s brass industry.

The program will be held at town hall on Kent Green Boulevard.

The Brass Valley began in 1802, when two metalworking families joined forces to manufacture brass.

Business soared during the War of 1812 with the demand for buttons, and soon brass parts became essential in the age of steam and electricity.

As large-scale brass manufacturing grew across what became known as Brass Valley, mill towns along the river, such as Torrington and Waterbury, developed into thriving cultural centers. This continued until 2014, when the last plant closed.

Books will be available for sale and signing.

The program is presented in collaboration with the Connecticut Antique Machinery Association
