Eugene O’Brien (Birthname: Louis O’Brien b. November 14, 1880 in Boulder, Colorado – d. April 29, 1966 in Los Angeles, California) was a silent film star and stage actor. He studied medicine at the University of Colorado at Boulder but was keener on the stage than becoming a doctor. O’Brien switched to civil engineering under his family’s guidance, but his heart was still set on becoming an actor. He moved to New York City and was “discovered” by theatrical impresario Charles Frohman who signed O’Brien to a three-year contract and put him in The Builder of Bridges, which opened on Broadway at the Hudson Theatre on October 26, 1909.Cinema Treasures | Hudson TheatreHudson Theater – New York City Landmark – JimsDeli NYC Guide O’Brien made his name playing opposite Ethel Barrymore, in a revival of Sir Arthur Wing Pinero’s play Trelawny of the ‘Wells’, which opened at the Empire Theatre on New Year’s Day, 1911.
