The industrial history of the northern Berkshires will be traced in a free public lecture at 2 p.m. Sunday, June 8, at the Williams Inn.

John L. Sprague, whose father, Robert, co-founded Sprague Electric Co., will discuss how the area has transitioned from an industrial to a post-industrial economy and what the future might bring. He will speak in the Heritage Room of the Inn.

President of the company for 11 years, John Sprague joined it in 1959 as a research scientist and retired as chief executive officer in 1987. His latest book, "87 Marshall Street," is the story of Sprague’s headquarters in North Adams. The campus is now occupied by Mass MoCA.

Sprague’s lecture, which is sponsored by the Williamstown Historical Museum, will follow the museum’s annual meeting.
