The collection

In 1982, the Ohio History Connection (at that time the Ohio Historical Society) received the Albert J. Ewing Collection from a private collector• Over 5,000 glass plate negatives of various sizes• Still packed in original boxes in which Ewing bought his 

undeveloped dry plates • Some identifying information• Images dated ca. 1896‐1912• Most locations are small towns in southern Ohio 

and central West Virginia

– Studio– Itinerant– Industrial 

• OHC has numerous glass plate negatives collections– Can last for many years with careful and appropriate 

handling and storage– High level of detail; they scan beautifully!

The collection

A selection of the original plates have been exhibited twice: • January 2013‐June 2014 at the Ohio History Center• November 2015‐Fall 2016 at the Campus Martius Museum in 

Marietta

Over the past 8‐9 years, OHC has been working to digitize and make these images freely available online at OhioMemory.org

The images

Posed portraits of Appalachian residents • Material culture of the region on display• Livestock and family pets • Homes or businesses and personal property

Less formal portraits and photographs documenting daily life

Intimate moments, posthumous and memorial photographs

Built environment of the region: homes, farms, businesses, schools and towns

Remarkable representation of Appalachian life at the turn of the       20th century with a deep sense of place
