The Marine Chronometers at Greenwich is the fifth, and largest, of
the distinguished series of catalogues of instruments in the
collections of the National Maritime Museum. Housed at the Royal
Observatory Greenwich - the 'home of time' and the Prime Meridian
of the world - this extraordinary collection, which includes the
celebrated marine timekeepers by John Harrison (1693-1776), is
generally considered to be the finest of its kind in existence. The
book is however much more than just a catalogue, and includes an
accessible and engaging history of the chronometer, revealing why
these instruments were important in our scientific and cultural
history, and explaining, in simple terms, how they worked and were
used. A comprehensive Glossary and Bibliography are included to
ensure any technicalities are explained and that the reader has
suggestions for useful 'further reading'. Over 480 photographs and
illustrations, including many fine macro-photographs and line
drawings, illustrate the 'jewel-like' beauty of the chronometer's
construction and explain the function and subtleties of its
mechanism. A chapter on 'How the Chronometer was Made', describes
the fine sub-division of labour used to create these special
machines, from bare metal, right up to delivery on board ship, and
brief biographies of the makers tell the human story behind this
important nineteenth-century industry. Another chapter, 'The
Evolution of the Chronometer', aimed at collectors, historians and
curators, provides clearly structured information on assessing and
dating the chronometer, something many find difficult. And, for the
dedicated specialist, there is extensive tabulated data on the
technical structure of this important collection, a unique resource
for future research.
