The program is scheduled for 6 p.m. Wednesday, Feb. 18, at the society’s headquarters at 246 Main St. in Keene. Admission is free, though advance registration is required due to limited seating.

The film grew out of a family effort to preserve the story of the company before firsthand accounts were lost to time. David Kingsbury Frechette, whose great-grandfather Harry T. Kingsbury founded the business, began recording interviews with former employees several years ago. Those conversations eventually became the foundation for a documentary examining the firm’s transition from toy production to machine tool manufacturing during the mid-20th century.

The completed film was produced by Peter Frechette and later shared with the Historical Society, which is incorporating the screening into its current exhibition, Revolution, Reaction & Reform.

Organizers say the documentary offers a rare look at the people behind the machinery, drawing on archival footage and personal recollections to illustrate the company’s impact on the region’s industrial development.

The event is supported by the Kingsbury Fund, the Putnam Foundation and Fenton Family Dealership.

Founded nearly a century ago, the Historical Society of Cheshire County presents roughly 150 programs annually and maintains extensive collections tied to the region’s past. The society describes its mission as connecting people with local history through exhibitions, education and community events.

Those interested in attending the screening can reserve seats through the society’s website.
