"The Cavendishes flourished during the high tide of British aristocracy following the revolution of 1688-89, and the case can be made that this aristocracy knew its finest hour when Henry Cavendish gently laid his delicate weights in the pan of his incomparable precision balance. For this it took two generations and two kinds of invention, one in social forms and the other in scientific technique. This biography tells how it came to pass."--BOOK JACKET.

William Cavendish, the father of the first Earl, dissolved monasteries for Henry VIII. Bess, his second wife, was gaoler-companion to Mary Queen of Scots during her long imprisonment in England. Arbella Stuart, their granddaughter, was a heartbeat away from the throne of England and their grandson, the Lord General of the North, fought to save the crown for Charles I. With the help of previously unpublished material from the Chatsworth archives, The Devonshires reveals how the dynasty made and lost fortunes, fought and fornicated, built great houses, patronised the arts and pioneered the railways, made great scientific discoveries, and, in the end, came to terms with changing times.

A NEW YORK TIMES NOTABLE BOOK • NOW A MAJOR MOTION PICTURE Lady Georgiana Spencer was the great-great-great-great-aunt of Diana, Princess of Wales, and was nearly as famous in her day. In 1774 Georgiana achieved immediate celebrity by marrying William Cavendish, fifth duke of Devonshire, one of England’s richest and most influential aristocrats. She became the queen of fashionable society and founder of the most important political salon of her time. But Georgiana’s public success concealed an unhappy marriage, a gambling addiction, drinking, drug-taking, and rampant love affairs with the leading politicians of the day. With penetrating insight, Amanda Foreman reveals a fascinating woman whose struggle against her own weaknesses, whose great beauty and flamboyance, and whose determination to play a part in the affairs of the world make her a vibrant, astonishingly contemporary figure. Praise for The Duchess “Georgiana bursts from the pages of Amanda Foreman’s dazzling biography like the force of nature she undoubtedly was–passionate, political, addicted to gambling, and drunk on life. This is a stunning book about an astonishing woman.”–Simon Schama “Biography at its best . . . seamlessly merges a life and its times, capturing not just an individual but an age.”–The New York Times Book Review “Riveting . . . marvelously diverting.”–The New Yorker
