Edgar Hewett traveled the world visiting archaeological sites, as well as conducting research and excavations across the American Southwest, Mexico, and Guatemala. In addition to his own field work, he also trained many prominent archaeologists, including Sylvanus Griswold Morley, Alfred Kidder, J.P. Harrington, and John Fletcher. Additionally, Hewett’s education was open to women, the first archaeology program to allow their admission, among them Bertha Dutton, Francis Watkins, and Barbara Freire-Marrecco. His wife, Donizetta, a suffragist and active member of the community herself, frequently traveled with him.

Edgar Hewett continued working tirelessly in the field of archaeology, working with both the Museum of New Mexico and the School of American Research, both of which he served as each institutions first directors, until August of 1946, mere months before his death, December 31, 1946.
