Franz Anton Ketterer (1676–1749) was a German clockmaker. Ketterer, one of the founding fathers of the Black Forest clockmaking industry in Germany, was born in the village of Schönwald im Schwarzwald. He is chiefly remembered as one of the earliest makers of cuckoo clocks in the Black Forest. His family carried on the business of clockmaking, and his German descendants continue to manufacture weather instruments. According to another German text *3) Simon Dilger was the teacher of Anton Ketterer.
