The American architect Louis Kahn (1901-1974) is regarded as one of the great master builders of the twentieth century. With complex spatial compositions and a choreographic mastery of light, Kahn created buildings of archaic beauty and powerful universal symbolism. Nature was not only a source of inspiration, but also became increasingly important as a context for his buildings. Despite having been one of America’s foremost architects, Kahn realized only few buildings in his lifetime. Images courtesy: Vitra Design Museum, Design Museum London.
