History of paper

Although there were precursors such as papyrus in the Mediterranean world and amate in the pre-Columbian Americas, these are not considered true paper.^[2][3] Nor is true parchment considered paper:^[a] used principally for writing, parchment is heavily prepared animal skin that predates paper and possibly papyrus. In the 20th century with the advent of plastic manufacture, some plastic "paper" was introduced, as well as paper-plastic laminates, paper-metal laminates, and papers infused or coated with different substances to produce special properties.

19th-century advances in papermaking[edit]

Although cheaper than vellum, paper remained expensive, at least in book-sized quantities, through the centuries, until the advent of steam-driven paper making machines in the 19th century, which could make paper with fibres from wood pulp. Although older machines pre-dated it, the Fourdrinier papermaking machine became the basis for most modern papermaking. Nicholas Louis Robert of Essonnes, France, was granted a patent for a continuous paper making machine in 1799. At the time he was working for Leger Didot with whom he quarrelled over the ownership of the invention. Didot sent his brother-in-law, John Gamble, to meet Sealy and Henry Fourdrinier, stationers of London, who agreed to finance the project. Gamble was granted British patent 2487 on 20 October 1801. With the help particularly of Bryan Donkin, a skilled and ingenious mechanic, an improved version of the Robert original was installed at Frogmore Paper Mill, Hertfordshire, in 1803, followed by another in 1804. A third machine was installed at the Fourdriniers' own mill at Two Waters. The Fourdriniers also bought a mill at St Neots intending to install two machines there and the process and machines continued to develop.


However, experiments with wood showed no real results in the late 18th century and at the start of the 19th century. By 1800, Matthias Koops (in London, England) further investigated the idea of using wood to make paper, and in 1801 he wrote and published a book titled Historical account of the substances which have been used to describe events, and to convey ideas, from the earliest date, to the invention of paper.^[115] His book was printed on paper made from wood shavings (and adhered together). No pages were fabricated using the pulping method (from either rags or wood). He received financial support from the royal family to make his printing machines and acquire the materials and infrastructure needed to start his printing business. But his enterprise was short lived. Only a few years following his first and only printed book (the one he wrote and printed), he went bankrupt. The book was very well done (strong and had a fine appearance), but it was very costly.^{[116][117][118]}


Then in the 1830s and 1840s, two men on two different continents took up the challenge, but from a totally new perspective. Both Friedrich Gottlob Keller and Charles Fenerty began experiments with wood but using the same technique used in paper making; instead of pulping rags, they thought about pulping wood. And at about the same time, by mid-1844, they announced their findings. They invented a machine which extracted the fibres from wood (exactly as with rags) and made paper from it. Charles Fenerty also bleached the pulp so that the paper was white. This started a new era for paper making. By the end of the 19th-century almost all printers in the western world were using wood instead of rags to make paper.^[119]


Together with the invention of the practical fountain pen and the mass-produced pencil of the same period, and in conjunction with the advent of the steam driven rotary printing press, wood based paper caused a major transformation of the 19th-century economy and society in industrialized countries. With the introduction of cheaper paper, schoolbooks, fiction, non-fiction, and newspapers became gradually available by 1900. Cheap wood based paper also meant that keeping personal diaries or writing letters became possible and so, by 1850, the clerk, or writer, ceased to be a high-status job.


Early wood-based paper deteriorated as time passed, meaning that much of the output of newspapers and books from this period either has disintegrated or is in poor condition; some has been photographed or digitized (scanned). The acid nature of the paper, caused by the use of alum, produced what has been called a slow fire, slowly converting the paper to ash. Documents needed to be written on more expensive rag paper. In the 2nd half of the 20th century cheaper acid-free paper based on wood was developed, and it was used for hardback and trade paperback books. However, paper that has not been de-acidified was still cheaper, and remains in use (2020) for mass-market paperback books, newspapers, and in underdeveloped countries.

Determining provenance[edit]

Determining the provenance of paper is a complex process that can be done in a variety of ways. The easiest way is using a known sheet of paper as an exemplar. Using known sheets can produce an exact identification. Next, comparing watermarks with those contained in catalogs or trade listings can yield useful results. Inspecting the surface can also determine age and location by looking for distinct marks from the production process. Chemical and fiber analysis can be used to establish date of creation and perhaps location.^[120]
