Bruguière discovered photography while travelling to New York, where he met Eugene and Stieglitz, who introduced him to avant-garde photography through Camera Work and Photo-Secession. In 1906, he opened his own portrait studio in San Francisco and, from 1919, worked in New York. There, he worked as a commercial photographer for Vogue and Harper’s Bazaar, combining this work with his passion for theatre and becoming the official photographer of the Theater Guild. A large body of work was intended to become a film with Sebastian Droste entitled The Way, which was never completed. In 1928, he moved to London, where he produced the abstract film Light Rhythm. He continued his career until 1937, when he left photography for painting and sculpture, continuing to work in these fields until his death.
