    Subject: [HASTRO-L] From Celestial to Terrestrial Timekeeping: New book
    about William Cranch Bond, his sons, and observatory timekeeping

    Below please find a message from Dr. James Nye, chairman of the
    Antiquarian Horological Society, concerning _ From Celestial to
    Terrestrial Timekeeping_, a new book by Donald Saff about William Cranch
    Bond and his sons and their associations with Harvard College
    Observatory and the clockmaking firm of William Bond & Son.   As curator
    of Harvard's Collection of Historical Scientific Instruments, which
    holds the business records, casting patterns, and exquisite astronomical
    regulators by the firm, I had the privilege to write the book's
    introduction.
    
    If you are interested in observatories and precision timekeepers, this
    is a book for you!

    Dear All,
    
    I hope list members (and their institutions, departments and libraries)
    will be interested in a new publication from the AHS
    (http://www.ahsoc.org), which covers in depth the contributions of the
    Bond family of Boston to the recording of star time, maintaining
    accurate time at sea, and time distribution for the New England
    Railroads following the organization of time zones. William Cranch Bond
    and George Bond, Directors of the Harvard College Observatory, were
    distinguished for their celestial discoveries and contributions to
    positional astronomy. In 1866, even as he lay dying, Richard Fifield
    Bond gave instructions for the finishing touches of a clock escapement
    design that proved to be a masterpiece. Soon after, his specifications
    were embodied in three ground-breaking clocks that distributed time
    signals from Harvard College Observatory, Liverpool Observatory, and the
    Bonds' shop in Boston.
    
     From the construction of the first chronometer in America to their role
    in the development of celestial photography, the Bonds were pre-eminent,
    utilizing the telegraph system to provide and distribute accurate time,
    servicing and rating chronometers for navigation, and providing
    observations and calculations for determining longitude in surveys.
    
    At the 1851 Great Exhibition, the Bonds introduced the drum chronograph
    to the scientific community, combatting the human inaccuracies inherent
    in observing star transits. The system was greatly admired and
    universally employed. The Astronomer Royal, Sir George Airy, even coined
    a term for it: the 'American Method'.
    
    Don Saff, the author, is familiar to many from different fields, but in
    the history of science his best-known work has involved research in
    precision horology and coverage of Edward Howard, Charles Fasoldt, and
    John Harrison.
    
    Some reviews of the new book can be seen here:

    The book is 438 pages, casebound, 270mm x 210mm, in a buckram cloth
    cover and on 150gsm silk paper.
