Claude Antoine, comte Prieur-Duvernois

In 1792, Prieur-Duvernois was sent on a mission to the Army of the Rhine to announce the deposition of King Louis XVI, after having voted in favor of his execution.

[1] On 14 August 1793, he became a member of the Committee of Public Safety, where he allied himself with Lazare Carnot in the organization of national defence.

He avoided capture in the riots of Prairial Insurrection (20 May 1795), and was subsequently spared the attacks of moderates in the Thermidorian Convention.

In 1808 he was created a count of the Empire, and in 1811 he retired from the army with the grade of chef de brigade[1] (the equivalent of colonel).

In this role, he helped to establish the Institut de France, to adopt the metric system, and to found the Bureau des Longitudes.
