Gerrit Rietveld was one of the most important designers and architects of the 20th century. A trained carpenter, the Dutchman joined the De Stijl movement at an early age. From 1918 onwards, his works reflect the artistic ideals of the artists' group. Abstract compositions of lines and planes, predominantly in black, white, grey and the primary colours yellow, red and blue, were characteristic for his work. However, in search of ways to further develop his radical artistic ideas, Rietveld soon turned away from the De Stijl aesthetic and experimented with innovative materials such as laminated wood and aluminium until the end of the 1930s. These experiments ultimately resulted in the legendary Zig-Zag chair.
