Who broke the Rosetta code?

The Rosetta Stone, which was crucial in deciphering Egyptian hieroglyphs, was broken by Jean-François Champollion in the early 19th century. In 1822, he announced that he had successfully deciphered the inscriptions on the stone, which included Greek, Demotic, and hieroglyphic texts. Champollion's work laid the foundation for modern Egyptology and significantly advanced our understanding of ancient Egyptian writing and culture.
