From Nick Dodman, Gestetner, Wikipedia, "The Gestetner is a type of duplicating machine named after its inventor, David Gestetner (1854 – 1939). During the 20th century, the term Gestetner has been 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 1996, the Gestetner company was acquired by the Ricoh Corporation of Japan."
