“There was limited knowledge about the Navajo people until the investigations of Washington Matthews, in the 1880s. Later the Franciscan Fathers at the St. Michaels Mission published a wide-ranging study of Indian culture in 1910 in their Ethnologic Dictionary.” It was not until the 1920s that university anthropologists, with their rigorous scientific methods, began to intensively investigate the culture of native people.” (Lyon 1989)
