Sequoyah (ᏍᏏᏉᏯ Ssiquoya, as he signed his name, or ᏎᏉᏯ Se-quo-ya, as is often spelled in Cherokee; also known as George Gist or George Guess) (c.1770–1843), was a Native American polymath of the Cherokee Nation. In 1821, he completed his independent creation of the Cherokee syllabary, making reading and writing in Cherokee possible. His achievement was one of the few times in recorded history that a member of a pre-literate people created an original, effective writing system. His creation of the syllabary allowed the Cherokee nation to be one of the first North American Indigenous groups to have a written language. Sequoyah was also an important representative for the Cherokee nation, by going to Washington, D.C. to sign two relocations and trading of land treaties.
