As a printer Franklin helped produce three hymn books including "Gottliche Liebes und Lobes Gethone," "Vorspiel der Neuen Welt" and "Jacobs Kampff und Ritter-Platz". He also printed a numer of copies of Isaac Watt's "Psalms and Hymns." Playing the harp, glass dulcimer, guitar and experimenting with musical glasses, Franklin used his knowledge to print a treatise on aesthetics. A string quartet bears his name but is more accurately ascribed to Ignace Pleyel. ~ Keith Johnson, Rovi
