Mies van der Rohe in the context of "Zeev Aram"

Modern architecture, also called modernist architecture, or the modern movement, is an architectural movement and style that was prominent in the 20th century, between the earlier Art Deco and later postmodern movements. Modern architecture was based upon new and innovative technologies of construction (particularly the use of glass, steel, and concrete); the principle of functionalism (i.e. that form should follow function); an embrace of minimalism; and a rejection of ornament.

According to Le Corbusier, the roots of the movement were to be found in the works of Eugène Viollet-le-Duc, while Mies van der Rohe was heavily inspired by Karl Friedrich Schinkel. The movement emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the principal style for institutional and corporate buildings by postmodern architecture.

Brutalist architecture is an architectural style that emerged during the 1950s in the United Kingdom, among the reconstruction projects of the post-war era. Brutalist buildings are characterised by minimalist construction showcasing the bare building materials and structural elements over decorative design. The style commonly makes use of exposed, unpainted concrete or brick, angular geometric shapes and a predominantly monochrome colour palette; other materials, such as steel, timber, and glass, are also featured.

Descended from Modernism, brutalism is said to be a reaction against the nostalgia of architecture in the 1940s. Derived from the Swedish word nybrutalism, the term "new brutalism" was first used by British architects Alison and Peter Smithson for their pioneering approach to design. The style was further popularised in a 1955 essay by architectural critic Reyner Banham, who also associated the movement with the French phrases béton brut ("raw concrete") and art brut ("raw art"). The style, as developed by architects such as the Smithsons, Hungarian-born Ernő Goldfinger, and the British firm Chamberlin, Powell & Bon, was partly foreshadowed by the modernist work of other architects such as French-Swiss Le Corbusier, Estonian-American Louis Kahn, German-American Ludwig Mies van der Rohe, and Finnish Alvar Aalto.

Philip Cortelyou Johnson (July 8, 1906 – January 25, 2005) was an American architect who designed modern and postmodern architecture. Among his best-known designs are his modernist Glass House in New Canaan, Connecticut; the postmodern 550 Madison Avenue in New York City, designed for AT&T; 190 South La Salle Street in Chicago; IDS Tower in downtown Minneapolis; the Sculpture Garden of New York City's Museum of Modern Art; and the Pre-Columbian Pavilion at Dumbarton Oaks. His January 2005 obituary in The New York Times described his works as being "widely considered among the architectural masterpieces of the 20th century".

In 1930, Johnson became the first director of the architecture department of the Museum of Modern Art in New York. There he arranged for visits by Walter Gropius and Le Corbusier and negotiated the first American commission for Mies van der Rohe, after he fled Nazi Germany. In 1932, he organized with Henry-Russell Hitchcock the first exhibition dedicated to modern architecture at the Museum of Modern Art, which gave name to the subsequent movement known as International Style. In 1934, Johnson resigned his position at the museum.
