As a result of the Alien Property Custodian enactment during the First World War, the company lost their American branch and all of their U.S. patents. This caused the company great economic hardship. Later the depression and the mass production of new technologies like the radio and the electric record player in the 1920s virtually brought about the demise of the firm and its expensive instruments. Other companies with similar products like American Piano Company (Ampico) and Duo-Art also began to fade from the scene at this time.
