Publisher's Synopsis
The Bond family excelled in practical and theoretical work in astronomy, clock design, time distribution, celestial photography-assisting astronomers to map the sky, sailors to determine longitude at sea, and the New England Railroads to run to time. Don Saff charts both the Bond family history and their detailed practical and visionary work on ground-breaking clock designs. The drum chronograph, introduced at the 1851 Great Exhibition, combatted human error, and led to the Astronomer Royal coining a term, 'The American Method'. The Bonds put American horology firmly on the nineteenth century technological map.
