Scottish historian and political philosopher. He worked as a teacher before starting to write articles for the Edinburgh Encyclopedia and critical works on German literature in the 1820s. His first major philosophical work was Sartor Resartus (1833–34), which dealt with social values and is written in a mannered prose style. He established his reputation as a historian with his History of the French Revolution (1837). Carlyle's influence on the development of social and political ideas in Britain during the 19th century was considerable.
