On Heroes, Hero Worship, and the Heroic in History (1840) by

Thomas Carlyle (4 December 1795 - 5 February 1881) was a Scottish philosopher, satirical writer, essayist, historian and teacher. Considered one of the most important social commentators of his time, he presented many lectures during his lifetime with certain acclaim in the Victorian era. One of those conferences resulted in his famous work On Heroes, Hero-Worship, and The Heroic in History where he explains that the key role in history lies in the actions of the "Great Man", claiming that "History is nothing but the biography of the Great Man". A respected historian, his 1837 book The French Revolution: A History 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. He also wrote articles for the Edinburgh Encyclopaedia, and his Occasional Discourse on the Negro Question (1849) remains controversial. 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.Carlyle was born in Ecclefechan in Dumfriesshire. His parents determinedly afforded him an education at Annan Academy, Annan, where he was bullied and tormented so much that he left after three years. His father was a member of the Burgher secession church. In early life, his family's (and nation's) strong Calvinist beliefs powerfully influenced the young man. After attending the University of Edinburgh, Carlyle became a mathematics teacher, first in Annan and then in Kirkcaldy, where he became close friends with the mystic Edward Irving. (Confusingly, there is another Scottish Thomas Carlyle, born a few years later, connected to Irving via work with the Catholic Apostolic Church
