Bruguière discovered photography travelling to New York, where he met Eugene and Stieglitz, who introduced him to avant-garde photography with Camera Work and Photo-Secession. In 1906 he opened his own portrait studio in San Francisco and from 1919 in New York. Here he worked as a commercial photographer for Vogue and Harper’s Bazaar, combining his work with a passion for theatre and becoming the official photographer of Theater Guild. A large body of work was meant to become a movie with Sebastian Droste entitled The Way (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 until his death.
