The Cuckoo Clock: Pop Icon from Karlsruhe
The iconic design of the Black Forest cuckoo clock traces its roots to Karlsruhe, Germany. It was created in 1850 by railway enthusiast Friedrich Eisenlohr.
A Style Icon and Its Creator
Friedrich Eisenlohr found inspiration for the cuckoo clock in his architectural plans for railway stations in Baden. It’s no coincidence that the clock’s case resembles a charming signalman’s hut—Eisenlohr, a professor at the Karlsruhe Polytechnic, was responsible for designing most of the stations from the Baden State Railway, from 1838 on. His designs shaped key stations in Mannheim, Heidelberg, and Baden-Baden, as well as the old Karlsruhe station, which once stood near today’s State Theatre and served as a model for numerous stations in Baden. Over his career, Eisenlohr designed more than 300 signalmen’s huts, leaving a lasting mark on the region’s railway landscape.
Eisenlohr designed the cuckoo clock for a competition organized by Robert Gerwig, director of the Furtwangen watchmaking school, which was founded in 1850 to support the struggling Black Forest clockmaking industry. The winning design was produced in 1855 by Kreuzer, Gatz & Co. and quickly became a beloved romantic symbol, its influence extending far beyond the Black Forest.
Engineers from the Polytechnic Shaped Transportation and Urban Landscapes Across Baden
Civil engineer Robert Gerwig, a graduate of the Polytechnic, dedicated much of his career building transportation routes for the Baden Water and Roads Directorate, including the Black Forest Railway, known for its innovative design.
As a professor, Eisenlohr – whose statue decorates the main Court of the Karlsruhe Institute of Technology (KIT) - influenced a generation of architects, including Reinhard Baumeister, a pioneer of the garden city movement. From the 1870s to the mid-1890s, Baumeister designed numerous green districts in Baden, such as Mannheim’s Oststadt, parts of Heilbronn, Heidelberg’s Weststadt, and the redevelopment of former fortress areas in Rastatt. He also planned several picturesque railway routes through the scenic side valleys of the Rhine plain, including the Murg Valley, Rench Valley, and Breisach Railway—routes still popular with tourists today.

200 Years of Pioneering Spirit: The Birth of Scientific Mechanical Engineering
When mechanical engineer Ferdinand Redtenbacher was appointed to the Polytechnic School in 1841, he established nothing less than scientific mechanical engineering in Germany. The ambitious teaching of the Austrian-born Redtenbacher not only brought Karlsruhe international recognition in the engineering world but also became a driving force behind industrialization in Baden, Germany, and beyond.
Redtenbacher believed that mechanical engineering was more than just a trade — he saw it as a science grounded in mathematical and physical principles. At a time when mechanical engineering relied primarily on experience and craftsmanship, and engineers were seen as little more than skilled mechanics, Redtenbacher set out to make engineering more scientific and mathematical. He introduced mathematical and mechanical principles to the field in order to systematically understand and design machines.
His vision was to surpass England, which was far ahead in industrialization, by applying scientific methods to engineering development. In 1835, Germany's first railroad line, connecting Nuremberg and Fürth, had to rely entirely on imported components from Great Britain — from the rails and wagons to the locomotive, the coal, and even the engineer and fireman. By 1847, however, German locomotives had already surpassed their English counterparts in technical capability. One example was the Badenia, built by Maschinenfabrik Karlsruhe, a company founded in 1837 by Emil Kessler and Theodor Martiensen, both graduates of the Polytechnic. German mechanical engineering had come into its own, no longer dependent on its former pioneers for the era's most complex technologies.
In the 1850s, German heavy industry saw a major breakthrough, to which many of Redtenbacher's students contributed. Heinrich Buz, for example, collaborated with Rudolf Diesel and co-founded MAN, a company that developed the diesel engine and contributed to Germany's industrial revolution. Similarly, Eugen Langen worked alongside Nikolaus August Otto to develop the Otto engine, which earned a gold medal at the 1867 World's Fair in Paris and laid the foundation for modern internal combustion engines.
