Frank Harold Hanna Roberts Jr. (August 11, 1897 – 1966) was an American archaeologist and anthropologist, who was the final director of the Bureau of American Ethnology of the Smithsonian Institution.
He worked largely in the American West, including field research at the Lindenmeier site in Northern Colorado and Pueblo Bonito in New Mexico.
Roberts grew up in Laramie, Wyoming, and Denver, Colorado, before moving to Las Vegas, New Mexico in 1910, where his father was president of New Mexico Normal University.
He was an assistant curator at the Colorado State Museum in 1923 and 1924 before moving to Harvard University, where he earned a second master's (1926) and PhD (1926).
[2] He coined the term "Paleoindian" to describe the so-called Clovis peoples who were, at the time, thought to be the earliest humans in North America.
