Augustin Cochin (22 December 1876 – 8 July 1916) was a French historian of the French Revolution. Much of his work was posthumously published in an incomplete state after he was killed in action in World War I. Born in Paris, Cochin was the son of Denys Cochin, a Parisian deputy in the National Assembly with ties to the Vatican, and the grandson of Augustin Cochin, a French politician and writer. His Catholic upbringing helped him to remain detached from the French Revolution and study it historically in a new light.
