Arne Jacobsen 1902–1971
Arne Jacobsen was an architect and designer who approached his work from both perspectives, making major contributions to Functionalism and Danish Modern style. Born and raised in Copenhagen, Denmark, he won the silver medal for his chair design at the Exposition Internationale des Arts Décoratifs in Paris in 1925 while an architecture student at the Royal Danish Academy of Fine Arts. After winning the Danish Architect’s Association competition for his House of the Future design, he opened his own office in 1929. Jacobsen was forced to flee to Sweden in 1943 following the rise of the Nazi party, but later returned to Denmark ushering in a wave of landmark public and private commissions.
