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 for his invention of the cuckoo clock. His family carried on the business of clockmaking, and his German descendants continue to manufacture weather instruments.
