Well of course: but why let dull facts get in the way of a great film script?
(Although the origins of the first cuckoo clock remain unknown, evidence dates similar, though primitive, objects to the mid-17th century. The first known description of a coo coo clock dates back to 1629 when a German nobleman named Philipp Hainhofer described a clock belonging to Prince Elector August von Sachsen. In 1650, scholar Athanasius Kirche documented the elements of a mechanical cuckoo clock in an engraving in a handbook on music, Musurgia Universalis. In 1669, Domenico Martinelli penned a handbook on elementary clocks, Horologi Elementari, and described how the cuckoo call indicates the time.
The first Black Forest cuckoo clock is attributed to Franz Anton Ketterer, a clock maker from the village of Schönwald, who, inspired by the bellows of church organs, started incorporating the cuckoo’s sound into clocks. By the mid-18th century, many clock-making shops in the region were producing cuckoo clocks with wooden gears. Today, Ketterer is known as one of the founding fathers of the Black Forest clock making industry).
