Claude Joseph Rouget de Lisle was a French army officer and composer, best known for writing the "Marseillaise," the national anthem of France. Born on March 10, 1760, in Lons-le-Saunier, he became involved in the French Revolution, which inspired his famous song in 1792. The anthem reflects revolutionary ideals and has become a symbol of national pride. Rouget de Lisle's contributions to music extended beyond the "Marseillaise," as he composed various other pieces, but none achieved the same level of fame. He passed away on June 26, 1836, leaving a lasting legacy in French culture and history.
