This notebook belonged to Christian author and speaker Elisabeth (Howard) Elliot (1926–2015), who was a missionary to the Waodäni people of Ecuador in the 1950s with her husband, Jim Elliot. Elisabeth chose to stay and live with the tribe after a Waodäni hunting party killed Jim and four other missionaries in 1956. She returned to the United States in 1963. While in Ecuador, Elisabeth worked with the Waodäni to create a writing system for their language. This notebook, one of many, contains language data and grammar notes. The title written on the front reads, “Auca Language Notebook XIII” and “Transcription of Recorded Text.” The header on the first page reads, “Continued from notebook XII – Maenkamu, Aug. 22, 1959.”
