Up and Down Stairs: The History of the Country House Servant
Jeremy Musson - 2009
Up and Down Stairs brings to life this hierarchy, showing how large numbers of people lived together under strict segregation and how sometimes this segregation was broken, as with the famous marriage of a squire to his dairymaid at Uppark. Jeremy Musson captures the voices of the servants who ran these vast houses and made them work. From unpublished memoirs to letters, wages, and newspaper articles, he pieces together their daily lives from the Middle Ages to the 20th century. The story of domestic servants is inseparable from the story of the country house as an icon of power, civilization, and luxury. This is particularly true with the great estates such as Chatsworth, Hatfield, Burghley and Wilton. Jeremy Musson looks at how these grand houses were, for centuries, admired and imitated around the world.
A Brief History of Science
Thomas Crump - 2001
With sixteen pages of photographs, and vivid vignettes of scientists and their inventions, Crump guides readers through early attempts to measure time and space—from astronomical charts and calendars to Arabic numerals and algebraic notation—before he examines the birth of an essentially modern technology in the 1600s. With Galileo's telescopic exploration of the skies at the beginning of the seventeenth century and Newton's experiments with the prism and light at its end, the optical instruments fundamental to all scientific research had been invented. Crump then proceeds to electromagnets, cathode tubes, thermometers, vacuum pumps, X rays, accelerators, semiconductors, microprocessors, and instruments currently being designed to operate in subzero temperatures. Here, then, in an accessible, succinctly narrated volume, is the enduring human quest for knowledge through technology. Here, too, is the proof that what is knowable is, and has always been, far more compelling than what is known. "[Crump] provides lively summaries of the progress in different fields, and succeeds in breathing new life into familiar stories."—The Economist "Fascinating reading."—Publishers Weekly
