The Gestetner is a type of duplicating machine named after its inventor, David Gestetner (18541939). During the 20th century, the term Gestetner was used as a verb—as in Gestetnering. The Gestetner company established its base in London, filing its first patent in 1879. The business grew, remaining within the control of the Gestetner family, and acquiring other businesses. In 1995, the Gestetner company was acquired by the Ricoh Corporation of Japan. History David Gestetner was born in Hungary in 1854, and after working in Vienna and New York, he moved to London, England, filing his first copying patent there in 1879. A later patent in 1881 was for the Cyclostyle, a stylus that was part of the Cyclograph copying device. That same year, he also established the Gestetner Cyclograph Company to produce duplicating machines, stencils, styli, ink rollers and related products. The Gestetner works opened in 1906 at Tottenham Hale, north London, and employed several thousand people until the 1990s, operating in 153 different countries. Gestetner's inventions became an overnight success, and an international chain of branch offices that sold and serviced Gestetner products was established. The Gestetner Company expanded quickly during the early and mid-20th century. Management was passed to David Gestetner's son, Sigmund Gestetner, and from him to his sons, David and Jonathan. Gestetner acquired other companies during the years: Nashua (later changed to Nashuatec), Rex Rotary, Hanimex and Savin. In 1995 the international Gestetner Company, and it's brand, was acquired by the Ricoh company of Japan. The company was renamed NRG Group PLC, and markets and services Ricoh products under its three main brand names, primarily in Europe, South Africa and the Middle East, but also through dealers throughout the world. In Europe, Gestetner Group became NRG Group, which on 1 April 2007 became Ricoh Europe. On that date Ricoh merged its Gestetner dealer network with the Lanier dealer network that had been selling Lanier-branded products on behalf of Ricoh for the North American market. Ricoh indicated that the merger's rationale was based on the fact that both "Gestetner and Lanier brands have been marketing identical products for many years". Thus, Gestetner's American customers can simply substitute Lanier-branded products for previous Gestetner-branded products even though Lanier-branded products are the same as Ricoh and Savin.
