Charles G. Penney, like many of the government officials that lived throughout the nineteenth century, was a civil war veteran that took an Indian Agent position on the Pine Ridge Reservation in the late 1890’s. As Montezuma was gathering data during his off time as working on reservations as a physician, he reached out to several Indian agents asking them for lists of the Indians who were on their reservations, which ones were thought of to be educated, and which ones could speak and write the English language. Unfortunately, there is no correspondence or reply from Penney regarding this information. Outside of his general title and position in the government during the period, there isn’t a lot of information that I could find on him other than that he served as a reforming agent on the reservation I previously mentioned.
