Edward Duffield: Philadelphia Clockmaker, Citizen, Gentleman, 1730-1803

The first comprehensive study of the life and times of colonial Philadelphia clockmaker Edward Duffield

Edward Duffield (1730-1803) was a colonial Philadelphia clockmaker, whose elegant brass, mahogany, and walnut timekeepers stand proudly in major American museums and collections. Duffield, unlike other leather-apron ’mechanics, ’ was born rich and owned a country estate, Benfield, and many more properties. He was deeply involved in civic and church affairs during crucial years in American history--his lifelong close friend, Benjamin Franklin, was staying at Duffield’s Benfield estate when Franklin, Thomas Jefferson, and John Adams first discussed the Declaration of Independence. Sally, Franklin’s daughter, brought her family there for extended periods during the Revolution and Franklin’s wife, Deborah, was best friends for fifty years with Duffield’s mother-in-law. Duffield was even one of three executors of Franklin’s will.

In this lavishly illustrated book, Bob Frishman catalogs and describes seventy-one known Duffield clocks and instruments and reveals how, during the mid-eighteenth century, they largely were not fabricated from scratch by isolated individuals. He contends that Duffield and his fellow clockmakers were not furniture-makers; they were mechanical artisans whose complex metal machines rang the hours and steadily ticked inside wooden cases made by others. Existing books on Philadelphia clocks have focused on these artifacts as furniture, including their woodwork, cabinetmakers, and decorative aspects. However, 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.

Far more than a treatise on pre-industrial horological timekeeping, this book tells the compelling stories of a man, a city, and an era, while deepening our appreciation for Duffield’s stately sentinels--often a colonial American family’s most valuable possession--and the times and places in which their makers lived.

Bob Frishman was introduced to horology--the science of timekeeping--on Thanksgiving Day, 1980, when he was invited into the overflowing cellar of a collector and dealer of antique clocks, watches, tools, and machinery. Had Bob stayed home that day, or not left the holiday dining table and gone down those basement stairs, this book would not have been written.

Nor would Bob’s other horological efforts during the past four decades ever have happened: eight thousand mechanical clocks repaired; two thousand antique clocks and watches restored and sold; hundred-plus articles and reviews published; hundred-plus in-person and virtual lectures delivered to horological and general audiences here and abroad; annual NAWCC symposia organized at the Winterthur Museum, the Museum of Fine Arts, Boston, the Henry Ford Museum, and the Museum of the American Revolution; and exhibits created and mounted by him at venues including the Horological Society of New York and the Willard House & Clock Museum.

Bob is a Silver Star Fellow of the National Association of Watch and Clock Collectors, and a Liveryman of the Worshipful Company of Clockmakers in London. As a dedicated supporter of other venerable cultural institutions, he is a Proprietor of the Boston Athenaeum, holder of Share Number 8 of the Library Company of Philadelphia, a member of the Grolier Club, the American Antiquarian Society, and the Ross Society of the Museum of Fine Arts, Boston.

He continues to operate Bell-Time Clocks in Andover, Massachusetts, where he lives with his wife, author Jeanne Schinto.
