Luigi Moretti (1907–1973) was an Italian architect known for his expressive modernism and sculptural approach to design. Initially associated with Fascist-era monumental architecture, he later embraced organic forms and parametric experimentation. His most famous works include the Casa delle Armi in Rome, the Watergate Complex in Washington, D.C., and the Il Girasole apartment building. Moretti’s architecture explored the intersection of structure, mathematics, and aesthetics, influencing later developments in computational design. His legacy, though complex, remains significant in shaping postwar modernism, blending rationalism with fluid, dynamic forms.
