Adolf Loos was an Austrian architect and writer active in Vienna in the early 20th century. He opposed the ornamentation and historicism prevalent in contemporary architecture and sought to develop a pre-modern style suited for his time. Through writings like "Ornament and Crime" he formulated a literary intervention criticizing ornamentation and arguing for unornamented architecture reflecting utility and modern life. This informed his architectural interventions like the Goldman & Salatsch building which featured a stark, unornamented design focused on function over decoration. Loos' rational approach to design drew from thinkers like Kant and Dewey and had a significant influence on the development of modern architecture.
