At more than 1,300 pieces, the Maine State Museum’s collection of Maine silver is the largest anywhere.
With that large collection has come the responsibility to conduct research. Over several decades, current and past Maine State Museum staff members and volunteers have tirelessly and quietly carried out these Herculean research efforts, focusing on the development of the first comprehensive list identifying Maine silversmiths, goldsmiths, jewelers, silverplaters, and clock and watchmakers from 1760 to the early 1900s.
Former curator Ed Churchill, now retired, has spearheaded the research project, along with Ann Thomas and Kathy Kirkham. The checklist, now nearly 100 pages
