ABSTRACT
Although wallpaper was nothing new in the nineteenth century, the rise in demand and the need for choice encouraged the development of technologies to meet these desires. One of the major improvements in manufacture was the development of the continuous paper-making process devised by Frenchmen Louis-Nicolas Robert and Henry Fourdrinier. This was an important technology that, in conjunction with steam power and the slighter later adoption of the rotary system used in calico printing (c. 1840), ensured that large-scale production of wallpaper was possible.
