The son of a lawyer, Jean Baptiste Marie Charles Meusnier de la Place entered the engineering school of Mézières in 1774 as a lieutenant. After graduation he worked on the harbor of Cherbourg. In 1784 Meusnier was appointed to the Academy of Sciences, and then in 1787 he was promoted to capitaine and in 1788 to major.

With the arrival of the French Revolution, Meusnier was promoted to lieutenant colonel in July of 1789. In 1792 he was promoted to colonel of the 14th Infantry Regiment and then employed in the process of manufacturing money. That May Meusnier was sent to the Army of the South to serve under General Montesquiou and then in September he received a promotion to maréchal de camp and he returned to Paris. Next he served in the Ministry of War for a number of months.

In February of 1793 Meusnier was sent to the Army of the Rhine, and during the maneuvers that followed he was with the French force that became trapped at Mainz. As the enemy laid siege to Mainz, Meusnier distinguished himself defending the fort of Kastel. That April he led a sortie that seized Kostheim in the middle of the night, but he and his men were then forced to abandon the place due to the fire of the enemy. Later that same month he attempted to reach the isles of the Rhine, and then he retook Kostheim but again had to give it up. As the Siege of Mainz continued on, in May General Meusnier was promoted to général de division and he successfully seized the isle of Kopf during a night attack. In June he seized Burgereau, but on June 5th he was struck by grapeshot in the right knee while at the fort of Kastel. He was transported to Mainz but died there on June 13th, 1793.
