The Lives of the Most Eminent Literary and Scientific Men comprised ten volumes of Dionysius Lardner's 133-volume Cabinet Cyclopaedia (1829–1846). Aimed at the self-educating middle class, this encyclopedia was written during the 19th-century literary revolution in Britain that encouraged more people to read.
The Lives formed part of the Cabinet of Biography in the Cabinet Cyclopaedia. Within the set of ten, the three-volume Lives of the Most Eminent Literary and Scientific Men of Italy, Spain and Portugal (1835–37) and the two-volume Lives of the Most Eminent Literary and Scientific Men of France (1838–39) consist of biographies of important writers and thinkers of the 14th to 18th centuries. Most of them were written by the Romantic writer Mary Shelley. Shelley's biographies reveal her as a professional woman of letters, contracted to produce several volumes of works and paid well to do so. Her extensive knowledge of history and languages, her ability to tell a gripping biographical narrative, and her interest in the burgeoning field of feminist historiography are reflected in these works.
