The Cunningham Block in Millbury was constructed by, and named for Winthrop P. Cunningham (1820-1895), and his son and business partner, Russell Clark Cunningham (1845-1907). Winthrop Cunningham had come to Millbury in about 1837 and worked for Waters, Flagg & Harrington prominent gun manufacturers in town. His foundry work there brought him into a partnership with Matthias Felton in the Millbury Foundry Company. The Cunningham Block is sited on a prominent corner lot and built into the slope of the hill which drops down toward the river. I am especially fond of the curved corner facade and repetition of the paired round-arched windows on the second floor.
