Kew Observatory influenced and was influenced by many of the larger developments in the physical sciences during the second half of the nineteenth century, while many of the major figures involved were in some way affiliated with Kew. Lee T. Macdonald explores the extraordinary story of this important scientific institution as it rose to prominence during the Victorian era. His book offers fresh new insights into key historical issues in nineteenth-century science: the patronage of science; relations between science and government; the evolution of the observatory sciences; and the origins and early years of the National Physical Laboratory, once an extension of Kew and now the largest applied physics organization in the United Kingdom.
