Jean Gabriel Marchand, 1st Count Marchand (10 December 1765 – 12 November 1851) went from being an attorney to a company commander in the army of the First French Republic in 1791. He fought almost exclusively in Italy throughout the French Revolutionary Wars and served on the staffs of a number of generals. He participated in Napoleon Bonaparte's celebrated 1796-1797 Italian campaign. In 1799, he was with army commander Barthélemy Catherine Joubert when that general was killed at Novi. Promoted to general officer soon after, he transferred to the Rhine theater in 1800.
