Textophon wire recording device with accessories

The textophone was developed in 1929 by Semi Joseph Begun at Ferdinand Schuchardt AG, and distributed from June 1930 by Echophon AG who called it the "dailygraph." The company C. Lorenz AG took over the manufacturing and distribution in 1932, calling it the "textophone." Textophones recorded sounds on steel wire. The steel wire cassettes patented by Willy Hornauer in 1928 were easier to handle. According to advertising, possible applications included dictations, recording telephone calls, and "acoustic protocols."
