Jean-Paul Marat (24 May 1743 – 13 July 1793) was a physician, political theorist and scientist best known for his career in France as a radical journalist and politician during the French Revolution. His journalism became renowned for its fierce tone, uncompromising stance toward the new leaders and institutions of the revolution, and advocacy of basic human rights for the poorest members of society.
Marat was one of the most radical voices of the French Revolution. He became a vigorous defender of the sans-culottes, publishing his views in pamphlets, placards and newspapers, notably his L'Ami du peuple (Friend of the People), which helped make him their unofficial link with the radical, republican Jacobin group that came to power after June 1793.
Marat was assassinated by Charlotte Corday, a Girondist sympathizer, while taking a medicinal bath for his debilitating skin condition. In his death, Marat became an icon to the Jacobins as a revolutionary martyr, as portrayed in Jacques-Louis David's famous painting, The Death of Marat.
