Thomas Carlyle (4 December 17955 February 1881) was a British historian, satirical writer, essayist, translator, philosopher, mathematician, and teacher. In his book ''On Heroes, Hero-Worship, and The Heroic in History'' (1841), he argued that the actions of the "Great Man" play a key role in history, claiming that "the history of the world is but the biography of great men". Other major works include ''The French Revolution: A History'', 3 vols (1837) and ''The History of Friedrich II of Prussia, Called Frederick the Great,'' 6 vols (1858–65).A respected historian, his 1837 ''The French Revolution'' was the inspiration for Charles Dickens' 1859 novel ''A Tale of Two Cities'', and remains popular today. Carlyle's 1836 ''Sartor Resartus'' is a notable philosophical novel.
A great polemicist, Carlyle coined the term "the dismal science" for economics, in his racist essay "Occasional Discourse on the Negro Question," which remains controversial. He also wrote articles for the ''Edinburgh Encyclopaedia''.
Once a Christian, Carlyle lost his faith while attending the University of Edinburgh, later adopting a form of deism.
In mathematics, he is known for the Carlyle circle, a method used in quadratic equations and for developing ruler-and-compass constructions of regular polygons. Provided by Wikipedia
