Internationally renowned as one of the major achievements of modern architecture, the work of Alvar Aalto (1898-1976) was deeply rooted in the culture and the landscape of his native Finland. A Grand Duchy of Russia until the revolution of 1917, the newly independent state promoted architecture as a means of establishing its identity as a social democracy, and in Aalto found an architect with the ambition and talents to meet the challenge. Throughout a long and fertile career his work embraced almost all the key public institutions - town halls, libraries, theatres, churches, universities and government departments - as well as social housing and private dwellings, and he brought to buildings of every type and scale a profound concern for the physical and psychological needs of their individual users, as well as remarkable sensitivity to natural sites and materials and to the experimental qualities of architecture. The complete range of his work is examined through a study of recurring themes - the dialogue between nature and culture, the reciprocity of the individual and the collective, building and place.
