In the preface to his classic study of Albrecht Dürer, Erwin Panofsky referred to high- and postmedieval European art as a grand fugue that, as it was most often played, lacked a distinctively Germanic voice. In contrast to that of their more celebrated peers in France, the reputation of German artists in subsequent eras does not appear to have risen much higher. This is complicated by the irony that Germany’s notoriously chauvinistic art-historical establishment deprecated her uniquely important contributions to the evolution of post-Enlightenment architecture, its pedagogy, and its theory. Whether seen from a classic or romantic point of view, many of the enduring features of twentieth-century architecture and theory reflect specifically Teutonic concerns that were either later attributed to the French (by Siegfried Giedion), to the English (first by Hermann Muthesius then a generation later by Nikolaus Pevsner), or seen as an aesthetic dead end. Harry Francis Mallgrave, who is editor of architecture and aesthetics for the Texts & Documents Series at the Getty Center for the History of Art and the Humanities, has toiled for over a decade to correct these errors. His stunning new biography of the architect Gottfried Semper (1803–1879) is bound to exert a healthy influence on the way we approach the aesthetic achievements of the nineteenth century—and the twentieth.

If remembered at all by the public today, Semper’s name is associated with a handful of historicist gems that stud Vienna’s Ringstrasse as well as with the recently restored Dresden Opera House that now bears his name. But, as Mallgrave demonstrates, Semper was also in direct contact (and often in open conflict) with many of the century’s preeminent personalities, including Karl Marx, Friedrich Nietzsche, Richard Wagner, Jacob Burckhardt, Kaiser Franz Josef, “Mad” King Ludwig of Bavaria, Karl Friedrich Schinkel, Jakob Moleschott, Gottfried Keller, Henry Cole, and many others. In fact, Mallgrave’s detailed account of his contribution to the formation of Nietzsche’s and Wagner’s aesthetic doctrines will once again thrust Semper to center stage in the emergence of German modernism.

Mallgrave’s account of Semper’s achievement corrects many common misconceptions. In the first place, he shows that—at the hands of a master like Semper, anyway —historicism as practiced in the mid- and late nineteenth century was hardly a pedantic, formulaic application of the decorative trappings of past styles. In place of this persistent but flawed view, Mallgrave presents Semper vigorously confronting and transforming the conventions of architectural expression to accommodate changing programmatic, iconographic, and theoretical demands. Semper’s contributions and the related developments that followed in their wake constitute the inadequately understood body of work against which so many modernists ultimately revolted.

Yet Semper’s elevated spirit of renewal and improvement so suffuses high modernism that we have grown averse to perceiving its occurrence in previous generations. Avoiding the exhausted method of trying to interpret Semper’s architecture in light of his theory (or vice versa), Mallgrave reexamines each aspect independently and establishes a new analytical standard for understanding Semper’s achievements. The most important breakthrough comes in his analysis of Semper’s “theatricality” and its relationship to Friedrich Schinkel’s dramatic neoclassicism. Mallgrave allows us once again to appreciate Semper’s elegantly modeled urban monuments as worthy exemplars of the classical tradition.

Mallgrave’s performance also reminds us how rare biographies written according to traditional standards have become. Doctrinaire postmodernists are quick to pooh-pooh biography as an invalid literary undertaking because, as Foucauldians repeatedly chide us, the idea of the individual itself has perhaps come to an end. Mallgrave’s evident labor, his methodically patient examination of an enormous quantity of primary documents in several languages, his insistence on visiting all of Semper’s monuments and every potentially helpful archive, as well as his complete mastery of the secondary literature, are all habits of mind that remain utterly alien to the postmodernist. And the result is a biography as readable as it is revelatory.

As is often the case, however, those who would most likely benefit from reading Mallgrave’s Semper are probaby the least likely to crack its covers: Semper—or more precisely a posthumous mistranslation of his thought—was criticized shortly after his death for the kind of materialist preoccupations obsessing the academic architectural profession today. Much of the impetus for what we now recognize as the academic study of architectural history took shape either in deference to or as a reaction against Gottfried Semper’s wide-ranging theoretical activities. In this respect, biographical detail gives the reader a sturdy toehold for appreciating the more abstract dimensions of Semper’s thought. To know that Semper was the kind of man who was observed one evening in the early 1840s dejectedly skipping rocks off the façade of his first Dresden Hoftheater may not illuminate much about his theory or his practice, but it does illustrate his choleric temperament. It was this cantankerousness, even crankiness, that ultimately caused much of Semper’s personal and professional difficulties. As Mallgrave demonstrates, without the chain of unfortunate events precipitated by his role in the 1849 Dresden uprising, Semper might not have been forced to reconsider theoretical matters during the long years of his mid-career exile in Paris and London.

Semper’s theory is as difficult as it is popular. His prose style strains even native speakers, and Semper’s wide-ranging interests touched on the latest findings in archeology, ethnology, philology, technology, aesthetics, and higher mathematics as well as pertinent developments in the sister arts. Although the sheer scope of Semper’s interests was not sufficient to deter generations of historians from approaching his body of theory, no one was willing to take responsibility for this vast scholarly terrain. Scholars of the very highest caliber, including the late Wolfgang Herrmann, were only able to digest relatively small portions of Semper’s incredibly rich theoretical outpourings. And while Mallgrave’s book is dedicated to the memory of Herrmann and his wife, in many respects he has surpassed his mentor.

The bulk of Semper’s mature theory is set forth in the two stout volumes of Der Stil in den technischen und tektonischen Künsten, oder praktische Aesthetik (1860–63), the fruit of an agonizingly protracted publishing effort whose origins and development Mallgrave patiently chronicles. His poise in balancing the biographer’s task with that of the analytical historian is most evident here. And I suspect that it was Mallgrave’s concern with biographical issues that enabled him to break through the conventional logjam of viewing Semper’s theory as a function of the interplay between Semper’s novel themes: the so-called theory of dressing (Bekleidungstheorie), the theory of architecture’s four elements, and the theory of material transformation (Stoffwechseltheorie). Instead, Mallgrave takes a few paces back in order to consider the overall cultural sweep of Semper’s lifelong interests and presents him as a first-rate metaphysician of architecture.

Semper was consumed with the interplay between appearances and essences, and to the extent that appearances reveal essences, architecture quite literally becomes a grand stage for civic Bildung. Despite the modern appeal of certain features of his earlier polychrome-based theories (“brick should appear as brick, iron as iron” and so on), Semper stridently advocated an architecture of shimmering, ornamentally encrusted surfaces. For him, style was not a function of tectonic rigor or strict conformity of material to function, but rather an almost fractal splendor by which the symbolic and tectonic realms resonate throughout a building’s, or even a precinct’s, overall design.

A shining example is Semper’s plan for the Kunsthistorisches Museum in Vienna: iconographically, the building functions as a clock that, reading clockwise of course, presents the history of art chronologically along each façade. Vertically, the building also tells the evolutionary tale of the emergence of raw crafts to their mastery by great individual artists. The tectonic overlay, of increasing refinement from rugged lithic referentiality to delicate fenestration, shows the architect as the coordinator of this magnificent artistic-historical trajectory, all in service to the House of Hapsburg. The Kunsthistorisches is mirrored by the Naturhistorisches Museum, which taken with the New Hofburg, forms but a torso of his grandiose plan for an immensely complex and iconographically rich Imperial Forum.

Mallgrave traces this pulsing urban scenography to Semper’s theater projects, beginning with the aborted Dresden Forum and continuing through the ill-fated plans for a Munich Festspieltheater for Richard Wagner. Semper prided himself as a theater architect first and foremost. His pivotal insights on the nature of art, the choragic role of the architect, and the literalness of architecture’s primordial symbolism clarify his appeal first to Wagner, and through him, to the young Nietzsche. Indeed Semper’s taut balance of realism and idealism moved Wilhelm Dilthey to call him “the true successor to Goethe.” But Semper’s efforts were, in a sense, sabotaged by the pedantry of his admirers. On the one hand, Semper’s theories were hailed within the academy as a foundational text for the history of art, especially the applied arts. In this respect, Semper’s success as a realist endowed the new discipline with a methodology for dating the minor works of remote antiquity, primarily pottery and metalwork. At the same time, because Semper never wrote the third and final volume of Der Stil, the volume dedicated to architecture per se, the material that would have rounded out Semper’s realism was never presented to the public. To compound the matter, when his sons brought out a posthumous collection of shorter writings in 1884, a critical lecture from the London years was translated in such a way that made Semper appear to be an unvarnished materialist. The dilemma between Semper as realist and Semper as idealist was brought to a close just after the turn of the century when the Viennese art historian Alo is Riegl pegged him as the father of “materialist metaphysics.” Mallgrave ends his book with a sustained examination of the Semper-Riegl problem and demonstrates, with great subtlety, the magnitude of Riegl’s intellectual debt to Semper.

After being considered second only to Schinkel as Germany’s most accomplished architect for over a generation, Semper fell from grace among the community of professional architects. Again, the realist seeds Semper planted in the 1860s sprouted into ideas that eventually undermined his own metaphysics. From Josef Bayer’s aesthetic of structural evolution of the 1880s, to Otto Wagner’s emphasis on developing a modern ornament in the 1890s, to Adolf Loos’s preoccupation with the absence of ornament in the 1900s—each defined his modernity as an honest disagreement with the venerable old Semper. By 1910, Semper was perceived to be the antithesis of architectural greatness and so it remained until the mid-1970s and the emergence of a cottage industry in Semper scholarship. That all of Semper’s writings are once again in print over a century after his death testifies to their enduring significance. Thanks to Mallgrave’s study, without doubt the finest in any language, this incandescent figure can finally be appreciated and Germany’s sonorous voice in the great fugue binding the nineteenth and twentieth centuries has become more defined.
