Eight clippings from a paper titled The Argus with one of the Catonsville Biographies: A Series of Personal Sketches by George C. Keidel Ph. D.; IV. Dr. Adalbert J. Volck.
This biography was published in eight instalments in Catonsville, Maryland, in 1915. Adalbert Johann Volck (1828-1912), a Baltimore dentist who also drew Confederate cartoons and caricatures, had his country home there. Born in Augsburg, Bavaria, in Germany, as Adalbert Johann von Volzsck, he came to the US in 1848.
All I could find about biographer George Charles Keidel was his year of birth, 1868. The caricatures  and  are from Albert Shaw’s Abraham Lincoln; profusely illustrated with contemporary cartoons, portraits and scenes, New York: The Review of Reviews Corporation, Second Printing, February 1930.

‘Volck spent the war publishing for a minuscule group of no more than two hundred subscribers. (…) By definition he was not a Confederate but a Copperhead artist — a Northern etcher with Southern principles. (…) an underground printmaker during the Civil War.’ — Neely, Jr. & Holzer & Boritt, 1987
