John Locke FRS (29 August 1632 – 28 October 1704), English philosopher and physician regarded as one of the most influential of Enlightenment thinkers, widely known as the Father of Classical Liberalism.

His writings influenced Voltaire and Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries.
