His father, Charles Jules Waltner, was also a French artist and etcher who engraved religious subjects for specialized publishers from 1848.
[2] Waltner became known for his ability to render large color paintings by the likes of Rembrandt, Thomas Gainsborough and Jules Breton into etchings.
Owing to their relative large size, most Waltner prints that have survived till today were either protected behind glassed frames or part of a major collection.
