The visual arts in Finland started to form their individual characteristics in the 19th century, when Romantic nationalism was rising in autonomic Finland. The best known of Finnish painters, Akseli Gallen-Kallela, started painting in a naturalist style, but moved to national romanticism. Other notable world-famous Finnish painters include Magnus Enckell, Pekka Halonen, Eero Järnefelt, Helene Schjerfbeck and Hugo Simberg. Finland's best-known sculptor of the 20th century was Wäinö Aaltonen, remembered for his monumental busts and sculptures. Finns have made major contributions to handicrafts and industrial design: among the internationally renowned figures are Timo Sarpaneva, Tapio Wirkkala and Ilmari Tapiovaara. Finnish architecture is famous around the world, and has contributed significantly to several styles internationally, such as Jugendstil (or Art Nouveau), Nordic Classicism and Functionalism. Among the top 20th-century Finnish architects to gain international recognition are Eliel Saarinen and his son Eero Saarinen. Architect Alvar Aalto is regarded as among the most important 20th-century designers in the world; he helped bring functionalist architecture to Finland, but soon was a pioneer in its development towards an organic style. Aalto is also famous for his work in furniture, lamps, textiles and glassware, which were usually incorporated into his buildings.
