Author Bob Frishman will discuss the life and work of Edward Duffield (1730–1803), a colonial Philadelphia clockmaker whose elegant brass, mahogany, and walnut timekeepers stand proudly in major American museums and collections.

In this lavishly illustrated book, Bob Frishman catalogs and describes 71 known Duffield clocks. He contends that Duffield and his fellow clockmakers were not furniture-makers; they were mechanical artisans. Frishman, a professional horologist for nearly four decades, brings his vast expertise to bear on this first comprehensive study of Duffield’s life and work.
