Unsurprisingly, that complicated question is closely connected to the Ohio History Connection’s organizational history.
The Ohio History Connection was established as the Ohio State Archaeological and Historical Society in 1885 (Ohio State Archaeological and Historical Society [OSAHS] 1887a). Very soon afterward, the Society began acquiring objects for an Ohio archaeology collection in a public museum space in the Ohio Statehouse. At the first annual meeting, the Society reported that “in the [museum] cases now are Dr. Hart’s collection, some three thousand specimens, donated in September, 1885; the collection of Ohio State University, and a number of smaller donations, aggregating in all some five thousand specimens” (OSAHS 1887b:293). These are the earliest collections, managed by the Society’s secretary, Albert A. Graham. According to later accounts, Graham kept track of some of the objects by labeling them, but if he kept a catalog, it likely has not been preserved.
