During the late 1920s, Finnish architect and designer Alvar Aalto started to experiment with bending wood and collaborated with the furniture manufacturer Otto Korhonen on developing a number of innovative techniques. One piece in particular emerged out of this collaboration, the "L-Leg." Though it was initially designed with the iconic Stool 60 in mind, its structural properties—Aalto called it "the little sister of the architectural column"—made it ideal for a wide variety of products and it soon became a standard element of Aalto's Artek collection.
The span of his career, from the 1920s to the 1970s, is reflected in the styles of his work, ranging from Nordic Classicism of the early work, to a rational International Style Modernism during the 1930s to a more organic modernist style from the 1940s onwards. Together with his first wife Aino Aalto – would design not just the building, but give special treatments to the interior surfaces and design furniture, lamps, and furnishings and glassware. His furniture designs are considered Scandinavian Modern, in the sense of a concern for materials, especially wood, and simplification but also technical experimentation, which led to him receiving patents for various manufacturing processes, such as bent wood.
