From Wikipedia:
> The theory is primarily attributed to the Scottish essayist, historian, and philosopher Thomas Carlyle, who gave a series of lectures on heroism in 1840, later published as On Heroes, Hero-Worship, & the Heroic in History.
From that series of lectures:
1. (5 May) The Hero as Divinity. Odin. Paganism: Scandinavian Mythology
2. (8 May) The Hero as Prophet. Mahomet: Islam
3. (12 May) The Hero as Poet. Dante; Shakspeare
4. (15 May) The Hero as Priest. Luther; Reformation: Knox; Puritanism
5. (19 May) The Hero as Man of Letters. Johnson, Rousseau, Burns
6. (22 May) The Hero as King. Cromwell. Napoleon: Modern Revolutionism
Are any of those people scientists?
Carlyle is talking about political and cultural influence, not technological development. Using scientists that made great discoveries as a counter-example to the theory is a straw man argument.
