The cuckoo clock is by no means a modern invention.  This whimsical clock has deep roots in the storied tradition of clock making.  It is recorded that in the 3rd century B.C. Greek mathematician Ctesibius  invented a clock in which an owl signaled the hour with the use of a whistle sounded with water.  Perhaps that is the earliest ancestor to the cuckoo clock, but the familiar clocks that we know today have a history that dates back to the early 17th century.  

Historians have discovered  the first written description of a cuckoo clock that was penned in 1629 in Germany.  A courtier by the name of Philipp Hainhofer wrote a detailed description of a cuckoo clock that was owned by a member of the German royalty that is believed to have been produced somewhere outside the country.  

It is also known that about 1669 an Italian clock maker named Domenico Martinelli described in a manual on clock building how to make a clock with automation, much like a cuckoo clock.  Based on his work, this style of clock began to appear in diverse areas of Europe.  The earliest cuckoo clocks were made contemporaneously in various places, long before they became a specialty of the clock makers in the Black Forest.  Many legends were scripted to make it appear that the true birthplace of the cuckoo clock is indeed the Black Forest, but none of them have solid historical backing.  And since their publication, other finds have come to light to show the origins are more diverse.

One thing is not disputed however.  Once clock makers in Germany’s Black Forest began to produce them in the mid-18th century, cuckoo clocks became wildly popular throughout the area and country and the appeal of the Black Forest cuckoo clock spread to other countries.  By about 1750 several large clock making companies in the Black Forest were creating cuckoos with wooden gears that laid the mechanical foundation for all cuckoo clocks that followed.  While gears are now metal, mechanical-style cuckoos are not very different at all from their historical ancestors. 

Even if the cuckoo clock has broader roots, it is generally agreed that Black Forest clock makers popularized the clock that we know and love today.  The so-called Black Forest cuckoo clock, formed in the shape of a chalet with carved wood and pine-cone shaped weights, remains the most popular motif in today’s cuckoos.  While many traditional cuckoo clocks are still produced every year, electrical power is used in some modern clocks instead of weights, and many keep time digitally rather than rely on a pendulum.  However, true to their roots they continue to use weights and pendulums as ornamentation along with all the other quaint features that have made them a favorite for more than 350 years.
