William Bond and Son
fl. 1793 - 1977
William Bond & Son was founded by an English silversmith and watchmaker who settled in Boston. His son, the astronomer William Cranch Bond, joined him in the business. He built the first American-made marine chronometer, and the business was a major supplier and regulator of chronometers.
William Cranch Bond was an avid astronomer. He discovered a comet in 1811 and was named the first director of the Harvard College Observatory in 1839. His son, George Phillips Bond, not only joined him in the family business, but was also enthusiastic about astronomy. George P. Bond discovered a satellite and an additional ring of Saturn. He was a pioneeer in celestial and stellar photography. He succeeded his father as observatory director.
W. C. Bond and G. P. Bond also devised a break circuit device that attached to the escapement of a clock, which became the foundation of the new "American method" of determining longitude. It earned a Council Medal at the London Crystal Palace Exhibition of 1851.
The firm had many addresses in Boston. Documents and publications in the Bond Papers in the Collection of Historical Scientific Instruments give these locations:
