Harold S. Gladwin was a former New York City stockbroker who eventually left his position and moved to Santa Barbara, California.
In Santa Barbara, he met his future wife, Winifred, and William North Duane, who introduced Gladwin to his cousin, the archaeologist A.V.
[2] With Harold S. Gladwin's backing and funding, the Gila Pueblo Archaeological Foundation was able to conduct extensive excavations and research throughout the American Southwest.
One of the most significant contributions made by the foundation was the definition of the Hohokam culture, a task in which the young archaeologist Emil Haury played a key role.
The building that housed the foundation, now part of Eastern Arizona College, is listed on the National Register of Historic Places.
