Completed in 1909 along Huttenstraße in Berlin-Moabit, the AEG Turbine Factory (AEG Turbinenfabrik) designed by Peter Behrens (1868–1940) is universally acknowledged as the foundational landmark of modern industrial architecture. Serving as Artistic Advisor to the industrial giant Allgemeine Elektricitäts-Gesellschaft (AEG), Behrens elevated a utilitarian factory into a monumental temple of human labor, fusing monumental classical gravitas with honest structural steel and vast glass curtain walls.
1. Engineering the Great Hall: Three-Hinged Steel Trusses
To accommodate the manufacture and assembly of colossal steam turbines weighing hundreds of tons, Behrens collaborated with structural engineer Karl Bernhard to design an expansive column-free assembly hall:
- The Three-Hinged Arch Trusses: The structural skeleton is formed by 22 massive three-hinged steel portal frames spanning 25.7 meters (84 feet) wide and standing 207 meters (680 feet) long.
- Rhythmic External Pin-Joints: Along the side elevation, the steel stanchions are proudly exposed on the exterior façade, narrowing at their base to rest gracefully on cast-steel pin hinges anchored to concrete plinths.
- Inclined Glass Curtain Walls: Between the external steel columns, enormous glazed panels slant slightly inward toward the roofline, flooding the interior assembly floor with glare-free natural light.
2. Monumental Classical Gable & Corner Bastions
While the longitudinal flanks celebrate lightweight steel and glass, the main street façade facing Berlichingenstraße asserts majestic civic permanence:
The Polygonal Pediment & Corner Masses
Behrens crowned the gable end with a monumental polygonal concrete pediment bearing the engraved hexagonal AEG trademark. The heavy corner pylons are rendered with horizontal banded rustication; however, Behrens intentionally rounded their outer edges, visually revealing that they do not bear heavy corner structural loads, but serve as sculptural frames enclosing the great central glass sheet.
3. Behrens, Van de Velde & The Birth of Corporate Identity
Both Peter Behrens and Henry van de Velde were founding members of the Deutscher Werkbund in 1907. But while Van de Velde operated primarily through elite private patrons, educational academies, and cultural institutions, Behrens took the radical step of entering the heart of modern industrial capitalism.
At AEG, Behrens invented the concept of Corporate Identity (Gesamterscheinungsbild), designing everything from the company's trademark logo, letterheads, and catalogs to electric tea kettles, streetlamps, arc lamps, and factory complexes. Crucially, Behrens's Berlin studio served as the master training ground for the holy trinity of modern architecture: Walter Gropius, Ludwig Mies van der Rohe, and Le Corbusier all worked under Behrens during the construction of the AEG Turbine Hall.
4. Comparative Dialectic: Peter Behrens vs. Henry van de Velde
Behrens's industrial monumentality and Van de Velde's expressive craftsmanship defined the opposite poles of early German Werkbund modernism:
| Dimension | Peter Behrens (AEG Turbine Hall & Industrial Modernism) | Henry van de Velde (Werkbund Theatre & Art Nouveau Reform) |
|---|---|---|
| Primary Patronage | Industrial corporate conglomerates (AEG, Emil Rathenau); mass-production manufacturing. | Aristocratic cultural patrons (Harry Graf Kessler, Karl Ernst Osthaus), grand dukes, state academies. |
| Structural Aesthetic | Monumental tectonic classicism, exposed steel lattice arches, expansive industrial glass envelopes. | Organic kinetic lines (Linienkunst), sculptural cast concrete, undulating biological curves. |
| Design Scope | Comprehensive corporate design: corporate logos, industrial machinery, mass-market electric consumer appliances. | Comprehensive domestic synthesis (Gesamtkunstwerk): bespoke furniture, silver tea services, reform dresses, book typography. |
| Pedagogical Role | Master atelier mentor to Walter Gropius, Mies van der Rohe, and Le Corbusier in Berlin. | Founder of the Grand Ducal Arts and Crafts School Weimar, handpicking Gropius as his successor to create the Bauhaus. |
"A factory should not hide behind historicist Romanesque or Gothic masquerades. Modern industry is the defining spiritual and economic force of our epoch, and its buildings must possess the heroic dignity of ancient temples."
