Cynthia irwin williams legacy
Cynthia Irwin-Williams (April 14, 1936 – June 15, 1990) was an archaeologist of the prehistoric American Southwest. She received a B.A. in Anthropology from Radcliffe College in 1957; the next year she received a M.A. in the same field. In 1963 she completed her educational career in Anthropology with a PhD. from Harvard University. Beginning her career in the 1950s, Irwin-Williams was considered a "ground-breaker" in the archaeology field for women, like her friend and supporter Hannah Marie Wormington.

Archaeological career
She worked with her brother, Henry Irwin, a fellow archaeologist, in Colorado from the mid-1950s to 1960. In 1966 Irwin-Williams and her brother published a book of her findings from the Magic Mountain Site excavation performed for the Peabody Museum of Harvard University in 1959-1960. They also worked on the nearby and related LoDaisKa Site between 1958-1960.
In the 1960s she defined the Picosa culture, an Archaic culture of people from three locations with interconnected artifacts and lifestyles. It was named by Irwin-Williams for those areas: Pinto Basin (PI), Cochise Tradition (CO) and San Jose (SA), which all together is "Picosa". Irwin-Williams developed the sequence of Archaic culture for the Oshara Tradition, which followed the Picosa culture, during her work in the Arroyo Cuervo area of northwestern New Mexico. Irwin contended that the Ancient Pueblo People, or Anasazi, developed, at least in part, from the Oshara.
In 1962, Irwin-Williams led the team that first excavated the Hueyatlaco site in Mexico. The site became mired in controversy about the age of human habitation in the site, and Irwin-Williams never published a final report on the excavation despite decades of research.
Personal life
Cynthia Irwin-Williams was born April 14, 1936 in Denver, Colorado. After a long chronic illness, Irwin-Williams died on June 15, 1990 in Reno, Nevada.
