A. Hoen & Co. Lithocaustic Baltimore. - August Hoen patented his lithocaustic method (originally spelled lithokaustik) in 1860. This covered etching with a mix of citric acid and gum arabic so that the lithographer could see the progress of shaded patterns as they were etched into the stone. He continued to explore methods of producing fine gradations in shading. In 1880, August Hoen was granted several patents for a method of producing halftone prints using lithography.
