The document discusses Expressionist architecture, an avant-garde movement that sought to transform reality rather than imitate it. Expressionism emerged from Art Nouveau in the early 20th century and was influenced by the trauma of World War I, during which architects were freed from practical constraints. Notable Expressionist architects included Erich Mendelsohn, Joseph Maria Olbrich, Rudolph Steiner, Eero Saarinen, and Frank Gehry. Their works featured organic, non-rectilinear forms meant to express deeper meanings rather than mimic surface appearances.
