Worked on developing the syllabary for approximately 12 years, including working through skepticism and accusations of witchcraft from within his own community during the process.

Explicitly pursued the syllabary to give the Cherokee people their own means of written communication and preserve their language; the finished system was subsequently adopted as an official writing system by the Cherokee Nation.
