Increasingly, during the 1950s, modern architecture was criticized for its sterility, its "institutional" anonymity, and its disregard for regional building traditions. More varied and individual, as well as regionalist, modes of expression were sought by architects of the next generation, although the basic emphasis on structure and materials continued. This tendency was evident in the works of Louis Kahn, Edward Durell Stone, and Philip Cortelyou Johnson in the United States, and the architects of the so-called New Brutalism movement in England. A dynamic sculptural unity distinguished the buildings of Eero Saarinen and the late works of Le Corbusier. Other leading architects of this generation include Alvar Aalto of Finland, the Italians Pier Luigi Nervi and Paolo Soleri, and in Central and South America, Lúcio Costa, Oscar Niemeyer, Juan O'Gorman, and Felix Candela.
