Friedrich Eisenlohr

Jakob Friedrich Eisenlohr (23 November 1805, in Lörrach – 27 February 1854, in Karlsruhe) was a German architect and university professor. His design for a cuckoo clock, now known as the Bahnhäusle (train station) style, was the first to be mass-produced and helped make the clocks popular outside of Germany. Provided by Wikipedia
