Anchor Blocks were a German system of building blocks that were popular as a children’s construction toy in the late nineteenth and early twentieth centuries, notably in Europe. Dr F. Ad. Richter in Rudolstadt, Germany, began developing and manufacturing the system in 1879. The concept was based on the FROEBEL block system, which significantly impacted Frank Lloyd WRIGHT’s design philosophy.
Walter Gropius (1883 – 1969) was an architect born in Germany in the early twentieth century who contributed to the founding of the Bauhaus School. He lived in the United States after 1937 and taught at Harvard University, where he continued to defend the principles of Bauhaus, especially the use of functional materials and clean geometric designs.
