Harper was born and raised in the countryside of Southern New Jersey. He began art lessons at age 4 with a local artist, Winnie Garrison. He continued with her until age 17 when he departed the area for college, graduate school, and a career as a military attorney with the US Army, JAG Corps. Upon retirement, Harper returned to Southern New Jersey and to painting.
Harper is an emerging artist who works primarily in acrylics. His landscapes are often influenced by the subtle beauty of the local area: the fields, the architecture, and the marshes. His interior paintings currently reflect his fascination with shadows, both real and perceived.
