Cambridge, MA, Peabody Museum of Archaeology and Ethnology at Harvard University
The Peabody was founded in 1866 by George Peabody, with a focus primarily on the archaeology and ethnography of the Americas, but holding significant collections from other parts of the world. Egypt and Nubia is well represented principally through material associated with George Reisner.
On enquiring after British excavated material that might be in the Peabody in April 2017, Diana Zlatanovski, Collections Steward, advised that:
"Accession# 07-40 Came to us from the American Exploration Society via their Director Sara Stevenson. Some of the material is from excavations at Ballas and Nagada and Petrie is referenced in the documents from the AES [about 40 Predynastic pottery vessels].
Accession# 98-2 Appears to have come to us via Charles Loring in 1898. However, our catalog has Flinders Petrie recorded as both the collector and donor, so it’s not entirely clear. In a letter dated January 1898, General Loring asks the Peabody to send Flinders Petrie and University College a thank you letter for the material, assumingly because that is who he obtained it from.
969-30-50/8986, believed to be Greek in origin is rumored to have been excavated in Egypt by Petrie in 1886. It went through multiple hands before coming to us in 1969, so it’s hard to say if that attribution is correct."
