The Cherokee Sequoyah, in the early 19th century, working alone, created an entirely new syllabic system for writing Cherokee, which previously had no written language. He overcame great doubts among his people, taught it to others, and within about ten years, with no "help" from missionaries (whose "help" generally comes with strings attached, like pressure to convert to Christianity) most of the Cherokee Nation was literate.
