Expressionist architecture was an architectural movement in Europe during the first decades of the 20th century in parallel with the expressionist visual and performing arts that especially developed and dominated in Germany. Brick Expressionism is a special variant of this movement in western and northern Germany and in The Netherlands (Amsterdam School). In the 1950s, a second movement of expressionist architecture developed, initiated by the Ronchamp Chapel Notre-Dame-du-Haut (1950–1955) by Le Corbusier. This second and international movement is called "Expressionist architecture since the 1950s" (see below).
The term "Expressionist architecture" initially described the activity of the German, Dutch, Austrian, Czech and Danish avant garde from 1910 until 1930. Subsequent redefinitions extended the term backwards to 1905 and also widened it to encompass the rest of Europe. Today the meaning has broadened even further to refer to architecture of any date or location that exhibits some of the qualities of the original movement such as; distortion, fragmentation or the communication of violent or overstressed emotion.
The style was characterised by an early-modernist adoption of novel materials, formal innovation, and very unusual massing, sometimes inspired by natural biomorphic forms, sometimes by the new technical possibilities offered by the mass production of brick, steel and especially glass. Many expressionist architects fought in World War I and their experiences, combined with the political turmoil and social upheaval that followed the German Revolution of 1919, resulted in a utopian outlook and a romantic socialist agenda. Economic conditions severely limited the number of built commissions between 1914 and the mid-1920s, resulting in many of the most important expressionist works remaining as projects on paper, such as Bruno Taut's Alpine Architecture and Hermann Finsterlin's Formspiels. Ephemeral exhibition buildings were numerous and highly significant during this period. Scenography for theatre and films provided another outlet for the expressionist imagination, and provided supplemental incomes for designers attempting to challenge conventions in a harsh economicate.
Important events in expressionist architecture include; the Werkbund Exhibition (1914) in Cologne, the completion and theatrical running of the Grosses Schauspielhaus, Berlin in 1919, the Glass Chain letters, and the activities of the Amsterdam School. The major permanent extant landmark of Expressionism is Erich Mendelsohn's Einstein Tower in Potsdam. By 1925 most of the leading architects of Expressionism such as; Bruno Taut, Erich Mendelsohn, Walter Gropius, Mies van der Rohe and Hans Poelzig, along with other Expressionists in the visual arts, had turned toward the Neue Sachlichkeit (New Objectivity) movement, a more practical and matter-of-fact approach which rejected the emotional agitation of expressionism. A few, notably Hans Scharoun, continued to work in an expressionist idiom.
In 1933, after the Nazi seizure of power in Germany, expressionist art was outlawed as degenerate. Until the 1970s scholars commonly played down the influence of the expressionists on the later International style, but this has been re-evaluated in recent years.
Expressionist architecture was individualistic and in many ways eschewed aesthetic dogma, but it is still useful to develop some criteria which defines it. Though containing a great variety and differentiation, many points can be found as recurring in works of Expressionist architecture, and are evident in some degree in each of its works.
Political, economic and artistic shifts provided a context for the early manifestations of expressionist architecture; particularly in Germany, where the utopian qualities of expressionism found strong resonances with a leftist artistic community keen to provide answers to a society in turmoil during and after the events of World War I. The loss of the war, the subsequent removal of Kaiser Wilhelm II, the depravations and the rise of social democracy and the optimism of the Weimar republic created a reluctance amongst architects to pursue projects initiated before the war and provided the impetus to seek new solutions. An influential body of the artistic community, including architects, sought a similar revolution as had occurred in Russia. The costly and grandiose remodelling of the Grosses Schauspielhaus, was more reminiscent of the imperial past, than wartime budgeting and post-war depression.
Artistic movements that preceded expressionist architecture and continued with some overlap were the arts and crafts movement and art nouveau or in Germany, jugendstil. Unity of designers with artisans, was a major preoccupation of the Arts and Crafts movement which extended into expressionist architecture. The frequent topic of naturalism in art nouveau, which was also prevalent in romanticism, continued as well, but took a turn for the more earthen than floral. The naturalist, Ernst Haeckel was known by Finsterlin and shared his source of inspiration in natural forms.
The Futurist and constructivist architectural movements, and the dada anti-art movement were occurring concurrently to expressionism and often contained similar features. Bruno Taut's magazine, Frülicht included constructivist projects, including Vladimir Tatlins Monument to the Third International. However, futurism and constructivism emphasized mechination, and urbanism tendencies which were not to take hold in Germany until the Neue Sachlichkeit. Mendelsohn is an exception whose work bordered on futurism and constructivism. A quality of dynamic energy and exuberance exists in both the sketches of Erich Mendelsohn and futurist Antonio Sant'Elia. The Merzbau by Dada artist Kurt Schwitters, with its angular, abstract form, held many expressionist characteristics.
Influence of individualists such as Frank Lloyd Wright and Antoni Gaudí also provided the surrounding context for expressionist architecture. Portfolios of Wright were included in the lectures of Erich Mendelsohn and were well known to those in his circle. Gaudí was also both influenced and influencing what was happening in Berlin. In Barcelona, there was no abrupt break between the architecture of art nouveau and that of the early 20th century, where Jugendstil was opposed after 1900, and his work contains more of art nouveau than that of say Bruno Taut. The circle of der Ring, did know about Gaudí, as he was published in Germany, and Finsterlin was in correspondence. Charles Rennie Mackintosh should also be mentioned in the larger context surrounding expressionist architecture. Hard to classify as strictly arts and crafts or art nouveau, buildings such as the Hill House and his Ingram chairs have an expressionist tinge. His work was known on the continent, as it was exhibited at the Vienna Secession exhibition in 1900.
Many writers contributed to the ideology of expressionist architecture. Sources of philosophy important to expressionist architects were works by Friedrich Nietzsche, Søren Kierkegaard, and Henri Bergson. Bruno Taut's sketches were frequently noted with quotations from Nietzsche, particularly Thus Spoke Zarathustra, whose protagonist embodied freedoms dear to the expressionists; freedom to reject the bourgeois world, freedom from history, and strength of spirit in individualist isolation. Zarathustra's mountain retreat was an inspiration to Taut's Alpine Architecture. Henri Van de Velde drew a title page illustration for Nietzsche's Ecce Homo. The author Franz Kafka in his The Metamorphosis, with its shape shifting matched the material instability of expressionist architecture Naturalists such as Charles Darwin, and Ernst Haeckel contributed an ideology for the biomorphic form of architects such as Herman Finsterlin. Poet Paul Scheerbart worked directly with Bruno Taut and his circle, and contributed ideas based on his poetry of glass architecture.
Emergent psychology from Sigmund Freud and Carl Jung was important to expressionism. The exploration of psychological effects of form and space was undertaken by architects in their buildings, projects and films. Bruno Taut noted the psychological possibilities of scenographic design that, "Objects serve psychologically to mirror the actors' emotions and gestures." The exploration of dreams and the unconscious, provided material for the formal investigations of Hermann Finsterlin.
Throughout the 18th and 19th centuries philosophies of aesthetics had been developing, particularly through the work of Kant and Schopenhauer and notions of the sublime. The experience of the sublime was supposed to involve a self-forgetfulness where personal fear is replaced by a sense of well-being and security when confronted with an object exhibiting superior might. At the end of the nineteenth century the German Kunstwissenschaft, or the "science of art", arose, which was a movement to discern laws of aesthetic appreciation and arrive at a scientific approach to aesthetic experience. At the beginning of the twentieth century Neo-Kantian German philosopher and theorist of aesthetics Max Dessoir founded the Zeitschift für Ästhetik und allgemeine Kunstwissenschaft, which he edited for many years, and published the work Ästhetik und allgemeine Kunstwissenschaft in which he formulated five primary aesthetic forms: the beautiful, the sublime, the tragic, the ugly, and the comic. Iain Boyd Whyte writes that whilst "the Expressionist visionaries did not keep copies of Kant under their drawing boards. There was, however, in the first decades of this century [20th] a climate of ideas that was sympathetic to the aesthetic concerns and artistic production of romanticism.
A recurring concern of expressionist architects was the use of materials and how they might be poetically expressed. Often, the intention was to unify the materials in a building so as to make it monolithic. The collaboration of Bruno Taut and the utopian poet Paul Scheerbart attempted to address the problems of German society by a doctrine of glass architecture. Such utopianism can be seen in the context of a revolutionary Germany where the tussle between nationalism and socialism had yet to resolve itself. Taut and Scheerbart imagined a society that had freed itself by breaking from past forms and traditions, impelled by an architecture that flooded every building with multicolored light and represented a more promising future. They published texts on this subject and built the Glass Pavilion at the 1914 Werkbund exhibition. Inscribed around the base of the dome were aphoristic sayings about the material, penned by Scheerbart.
Another example of expressionist use of monolithic materials was by Erich Mendelsohn at the Einstein Tower. Not to be missed was a pun on the towers namesake, Einstein, and an attempt to make the building out of one stone, Ein stein. Though not cast in one pour of concrete (due to technical difficulties, brick and stucco were used partially) the effect of the building is an expression of the fluidity of concrete before it is cast. 'Architecture of Steel and Concrete' was the title of an 1919 exhibition of Mendelsohn's sketches at Paul Cassirer's gallery in Berlin.
Brick was used in a similar fashion to express the inherent nature of the material. Josef Franke produced some characteristic expressionist churches in the Ruhrgebiet in the 1920s. Bruno Taut used brick as a way to show mass and repetition in his Berlin Housing Estate "Legien-Stadt". In the same way as their Arts and Crafts movement predecessors, to expressionist architects, populism, naturalism, and according to Pehnt "Moral and sometimes even irrational arguments were adduced in favor of building in brick". With its color and pointillist like visual increment, brick became to expressionism what stucco later became to the international style.
Europe witnessed a boom in theatrical production in the early twentieth century. In 1896 there were 302 permanent theatres in Europe, by 1926 there were 2,499. Cinema witnessed a comparable increase in its use and popularity and a resulting increase in the number of picture houses. It was also able to provide a temporary reality for innovative architectural ideas.
Many architects designed theatres for performances on the stage and film sets for expressionist films. These were defining moments for the movement, and with its interest in theatres and films, the performing arts held a significant place in expressionist architecture. Like film, and theatre, expressionist architecture created an unusual and exotic environment to surround the visitor.
Built examples of expressionist theatres include Henry van de Velde's construction of the model theatre for the 1914 Werkbund Exhibition, and Hans Poelzig's grand remodelling of the Grosses Schauspielhaus. The enormous capacity of the Grosses Schauspielhaus enabled low ticket prices, and the creation of a "people's theatre". Not only were expressionist architects building stages, Bruno Taut wrote a play intended for the theatre, Weltbaumeister.
Expressionist architects were both involved in film and inspired by it. Hans Poelzig strove to make films based on legends or fairy tales. Poelzig designed scenographic sets for Paul Wegener's 1920 film Der Golem. Space in Der Golem was a three-dimensional village, a lifelike rendering of the Jewish ghetto of Prague. This contrasts with the setting of the Cabinet of Doctor Caligari, which was painted on canvas backdrops. Perhaps the latter was able to achieve more stylistic freedom, but Poelzig in Der Golem was able to create a whole village that "spoke with a Jewish accent."
Herman Finsterlin approached Fritz Lang with an idea for a film. Fritz Lang's film Metropolis demonstrates a visually progressive 'Futurist' society dealing with relevant issues of 1920s Germany in relation to labour and society. Bruno Taut designed an unbuilt theatre for reclining cinema-goers. Bruno Taut also proposed a film as an anthology for the Glass Chain, entitled Die Galoschen des Glücks(The Galoshes of Fortune) with a name borrowed from Hans Christian Andersen. On the film, Taut noted, "an expressionism of the most subtle kind will bring surroundings, props and action into harmony with one another". It featured architectural fantasias suited to each member of the Chain. Ultimately unproduced, it reveals the aspiration that the new medium, film, invoked.
The tendency towards abstraction in art corresponded with abstraction in architecture. Publication of Concerning the Spiritual in Art in 1912 by Wassily Kandinsky, his first advocacy of abstraction while still involved in the Blau Reiter phaze, marks a beginning of abstraction in expressionism and abstraction in expressionist architecture. The conception of the Einstein Tower by Erich Mendelson was not far behind Kandinsky, in advancing abstraction in architecture. By the publication of Kandinsky's Point and Line to Plane in 1926 a rigorous and more geometric form of abstraction emerged, and Kandinsky's work took on clearer and drafted lines. The trends in architecture are not dissimilar, as the Bauhaus was gaining attention and expressionist architecture was giving way to the geometric abstractions of modern architecture.
The term Brick Expressionism (German: Backsteinexpressionismus) describes a specific variant of expressionism that uses bricks, tiles or clinker bricks as the main visible building material. Buildings in the style were erected mostly in the 1920s. The style's regional centres were the larger cities of Northern Germany and the Ruhr area, but the Amsterdam School belongs to the same category.
Amsterdam's 1912 cooperative-commercial Scheepvaarthuis (Shipping House) is considered the starting point and prototype for Amsterdam School work: brick construction with complicated masonry, traditional massing, and the integration of an elaborate scheme of building elements (decorative masonry, art glass, wrought-iron work, and exterior figurative sculpture) that embodies and expresses the identity of the building. The School flourished until about 1925.
The great international fame of German Expressionism is not related to German Brick Expressionist architects, but to German Expressionist painters like Ernst Ludwig Kirchner, Karl Schmidt-Rottluff, Emil Nolde, Max Beckmann, Wassily Kandinsky and his German friends in Munich around 1908, and so on.
The legacy of expressionist architecture extended to later movements in the twentieth century. It had an influence on its immediate successor, modern architecture, as well as Art Deco. The new objectivity (Neue Sachlichkeit) art movement arose in direct opposition to expressionism. Expressionistic architecture today is an evident influence in deconstructivism, the work of Santiago Calatrava, and the organic movement of blobitecture.
Another movement that grew out of expressionism to become a school in its own right is Metaphoric architecture which includes elements of biomorphism and Zoomorphic architecture. The style is very much influenced by the form and geometry of the natural world and is characterised by the use of analogy and metaphor as the primary inspiration and directive for design. Perhaps the most prominent voice of the Metaphoric architectural school at present is Dr. Basil Al Bayati whose designs have been inspired by trees and plants, snails, whales, insects, dervishes and even myth and literature. He is also the founder of the International School of Metaphoric Architecture in Málaga, Spain.
Many of the founders and significant players in expressionist architecture were also important in modern architecture. Examples are Bruno Taut, Hans Scharoun, Walter Gropius, and Mies Van der Rohe. By 1927 Gropius, Taut, Scharoun and Mies were all building in the international style and participated in the Weissenhof Estate. Gropius and Mies are better known for their modernist work, but Gropius' Monument to the March Dead, and Mies' Friedrichstrasse office building projects are basic works of expressionist architecture. Le Corbusier started his career in modern architecture but took a turn for a more expressionist manner later in life.
First identified at the Exposition Internationale des Arts Décoratifs et Industriels Modernes in 1925, art deco shares some characteristics of expressionism and is likely to have been influenced directly by the Expressionist movement - particularly the activities of the Weimar Bauhaus - and more generally with the factors and politics that influenced both movements at the time, such as socialism and mechanisation. In common with art nouveau and expressionism they are interested in decorative effects that break with the past and reflect a new modernity. The bold use of zigzag and stepped forms, and sweeping curves and chevron patterns. New materials are employed in new ways such as glass, aluminum, and stainless steel. Later examples of Art Deco, particularly in New York City can be seen as a Transatlantic equivalent of European expressionism.
The influential architectural critic and historian, Sigfried Giedion in his book Space, Time and Architecture (1941) dismissed Expressionist architecture as a side show in the development of functionalism. In the middle of the twentieth century, in the 50s and 60s, many architects began designing in a manner reminiscent of expressionist architecture. In this post war period, a variant of expressionism brutalism had an honest approach to materials, that in its unadorned use of concrete, was similar to the use of brick by the Amsterdam School. The designs of Le Corbusier took a turn for the expressionist in his brutalist phase, but more so in his Notre Dame du Haut. In Mexico, in 1953, German émigré Mathias Goeritz, published the "Arquitectura Emocional" (Emotional architecture) manifesto where he declared that "architecture's principal function is emotion."  Modern Mexican architect Luis Barragán adopted the term that influenced his work. The two of them collaborated in the project Torres de Satélite (1957–58) guided by Goeritz's principles of Arquitectura Emocional. Another mid-century modern architect to evoke expressionism was Eero Saarinen. A similar aesthetic can be found in later buildings such as Eero Saarinen's 1962 TWA Terminal at JFK International Airport. His TWA Terminal at JFK International Airport has an organic form, as close to Herman Finsterlin's Formspiels as any other, save Jørn Utzon's Sydney Opera House. It was only in the 1970s that expressionism in architecture came to be re-evaluated in a more positive light. More recently still, the aesthetics and tactility of expressionist architecture have found echo in the works of Enric Miralles, most notability his Scottish Parliament building, deconstructivist architects such as Zaha Hadid and Daniel Libeskind, as well as Canadian Aboriginal architect Douglas Cardinal.
