HISTORY OF PULP AND PAPERMAKING 



Although the Egyptians are sometimes given credit for the earliest 

 development in the manufacture of paper, more recent research has 

 developed the fact that the Chinese must be credited with the first man- 

 ufacture of paper. The art of papermaking was known in China long 

 before the Christian era. It is likely that the art of papermaking 

 was transmitted from China across India to Persia and Arabia. It 

 is known that the Saracens carried the practice of the art to Spain 

 after their conquest of that country in the 8th century. The industry 

 was gradually developed, but spread very slowly through Europe. 

 From Spain it went to Italy where a paper mill was first operated at 

 Fabriano in the year 1150. This became an important center for 

 papermaking and it is said that paper is still made there at the present 

 time. The first paper mill in France was established in 1189; in Ger- 

 many in 1390; and the date of 1330 is given as the time of the first paper 

 mill in England. 



The introduction and development of papermaking machinery was 

 very slow, because of the current opposition to all forms of labor-saving 

 machinery during the Middle Ages. Forms of paper made in the earliest 

 paper mills in England are still extant and it is generally accepted that 

 the very best kinds of paper were made on the old-fashioned hand presses 

 in the earliest days. In this country early records show that the first 

 paper mill was established in 1690 by William Rittenhouse near Phil-
