The Navajo language is so complex that very few people besides the Navajo speak it. That’s what made it the ideal template for a secret code used to transmit military information during World War II. The Navajo who created the code and used it to save thousands of lives were called the Code Talkers. Their story is told in the documentary film “True Whispers.” Betsy Cook, a linguist and educator who has taught on the Navajo Reservation since 1977, will introduce the film. After the film, she will answer questions about the Navajo language and the Code Talkers
