Danish design is well-known around the world for its clean lines and refinement. It rose to prominence in the 1940s and 1950s, when the light and simple design of Danish furniture complemented the clean lines of modern International Style architecture. The term "danish design" was first used by American architect Louis Kamper to describe his own work after he studied under Finnish architect Alvar Aalto. In an interview with Design Observer, Kamper said that he took inspiration from Scandinavian design, especially that of Denmark's Børnehave (children's home) designed by Sven Hansen between 1930 and 1935. He also noted the influence of German design during this period. Scandinavia was one of the first regions in Europe to embrace industrial design. The design industry in Denmark, Sweden, and Norway grew rapidly in the 1920s and 1930s, attracting many talented designers. In addition, these countries had a small population with high standards of living, which meant there was plenty of money to spend on beautiful objects. During this time, Danish designers were influenced by the functionalism found in Germany's Bauhaus school and France's Citroën car company. Functionalist design focused on designing useful objects that could be mass-produced in large quantities.
