- US astronomer
who established the Harvard College Observatory as a centre of astronomical
research. Much of his work as done in collaboration with his son
George
Phillips Bond. He also designed chronometers.
Bond was born in Falmouth, Maine, and worked as a watchmaker. An amateur
astronomer, he was one of the independent observers who discovered
the comet of 1811. He was commissioned by Harvard College to investigate
the equipment at observatories in England during a trip he made there
in 1815, and in 1839 Harvard invited him to move his private observatory
into their premises. Bond thus became the first director of the Harvard
College Observatory.
William and George Bond discovered Hyperion (the eighth satellite
of Saturn) 1848 and the Crêpe Ring (a faint ring inside two
bright rings) around Saturn 1850. Their observation that stars could
be seen through the Crêpe Ring led to their conclusion that
the rings of Saturn are not solid.
The two Bonds also collaborated on the development of photographic
techniques for astronomy. They took superior photographs of the Moon,
and the first photographs of stars.
