William and Georgina Cowper-Temple were significant figures in nineteenth-century Britain. William Cowper-Temple, later Lord Mount Temple, was private secretary to one Prime Minister, Lord Melbourne, and minister in the government of Lord Palmerston. He sought to improve the nation's health and rebuild London, and famously amended the Education Act in 1870. His charismatic wife, Georgina, was also champion of diverse social and moral reforms, and friend to such worthies as John Ruskin, Dante Gabriel Rossetti, Frances Power Cobbe and Mrs Oscar Wilde. In the first full-length biography of this distinguished couple, James Gregory explores the Cowper-Temples' roles within Whig-Liberalism, philanthropy and social reform, and provides a fascinating insight into the private lives of two aristocrats dedicated to using their powers of influence to alleviate problems in Victorian society.
