The Wasmuth portfolio (1910) is a two-volume folio of 100 lithographs of the work of the American architect Frank Lloyd Wright (1867–1959).
Titled Ausgeführte Bauten und Entwürfe von Frank Lloyd Wright, it was published in Germany in 1911 by the Berlin publisher Ernst Wasmuth, with an accompanying monograph by Wright. It contained plans and perspectives (in linework only) of buildings from 1893–1909. It was the first publication of any of Wright's work to appear anywhere in the world, as Wright had not published any of his work in his twenty previous years of activity in the United States.
The portfolio is significant as a link between Wright's pioneering American architecture, and the first generation of modernist architects in Europe. Wright toured Europe for a year from October 1909 through October 1910, partly to support the publication of the portfolio, but also to experience first-hand a great deal of European architectural history.
Wright's early influence in northern Europe is unquestionable: Le Corbusier is known to have had and shared a copy, Czech architect Antonin Raymond and Austrian architects Rudolf Schindler and Richard Neutra all re-located to the United States in hopes of working for Wright, and one look at Willem Marinus Dudok's 1924 Hilversum Town Hall betrays its origins. At the time of the portfolio's publication, three major influential architects of the twentieth century (Le Corbusier, Ludwig Mies van der Rohe and Walter Gropius) were all working essentially as apprentices in the atelier of Peter Behrens in Berlin, where it has been said that work stopped for the day when the portfolio arrived. If this story is true, it reveals the magnitude of the immediate impact of Wright's architecture in European circles, since Behrens could have conceivably received a copy of the Wasmuth portfolio merely days or weeks after its publication.
