Happy Birthday Adolphe Loos!! The Austrian architect was born in 1870. When contemplating architecture, he believed reason should determine the design. After spending a year in the army, he studied at the College of Technology in Dresden. Loos worked for a time in the US and was influenced by architect Louis Sullivan. He returned to Austria to eventually open his own practice. The Steiner House, built in 1910, was an important design in modern architecture that established Adolphe Loos’ reputation.
