New Film About Native American Languages

Below is the description for this 6 minute trailer:

This is the funding reel for one-hour documentary on John Peabody Harrington, who, from 1907 until his death in 1961 amassed the largest amount of linguistic notes on Native American languages in North America. Some of the languages he recorded have had no speakers in 60 years, but thanks to his notes, these tribes have been able to revive their languages.
