Walter Gropius (Berlin, May 18, 1883 – Boston, July 5, 1969) was a German architect, theorist and teacher, who founded the Bauhaus school.
Gropius created innovative designs that borrowed materials and methods of construction from modern technology. This advocacy of industrialized building carried with it a belief in team work and an acceptance of standardization and prefabrication. Using technology as a basis, he transformed building into a science of precise mathematical calculations.
