It was founded in 2013 by four linguists: Uldis Balodis, who has since published a grammar of the Yuki[1] language, Jessica Kirchner, whose doctoral work had included engagement with the Kʷak̓ʷala language, Timothy Henry-Rodriguez, who had written a pedagogical grammar of Ventureño Chumash[2] for his dissertation, and Neil Alexander Walker, who has since published a grammar of the Southern Pomo[3] language.

In 2014, a WIELD board member located the last fluent speaker of the Wappo language, and he and another board member made two trips to make audio recordings of Wappo before the speaker died.
