Edgar Lee Hewett, as an ethnologist with the School of American Archeology of the Archeological Institute of America in Santa Fe, met and hired John P. Harrington in 1909. But Harrington was already more or less doing research and working on Native American languages in the Southwest during this time. (e.g. From September 1911 to June 1912, he served as assistant curator of the Museum of New Mexico at Santa Fe.)
