Ulman Strother in 1390 started his paper mill at Nuremberg in Bavaria which was the first paper mill known to have been established in Germany, and is said to have been the only one in Europe then manufacturing paper from linen rags.

Among the privy expenses of Henry VII of the year 1498 appears the following entry: "A reward given to the paper mill, 16s. 8d." This is probably the paper mill mentioned by Wynkin de Worde, the father of English typography. It was located at Hertford, and the water mark he employed was a star within a double circle.

The manufacture of paper in England previous to the revolution of 1688 was an industry of very small proportions, most of the paper being imported from Holland.

The first paper mill established in America was by William Rittenhouse who emigrated from Holland and settled in Germantown, Pa., in 1690. At Roxborough, near Philadelphia, on a stream afterwards called Paper Mill run, which empties into the Wissahicken river, was located the site which in company with William Bradford, a printer, he chose for his mill. The paper was made from linen rags, mostly the product of flax raised in the vicinity and made first into wearing apparel.

It was Reaumer, who in 1719 first suggested the possibility of paper being made from wood. He obtained his information on this subject from examination of wasps' nests.

Matthias Koops in 1800 published a work on "Paper" made from straw, wood and other substances. His second edition appeared in 1801 and was composed of old paper re-made into new. Another work on the subject of "Paper from Straw, &c.," by Piette, appeared in 1835, which said work contains more than a hundred pages, each one of which was made from a different kind of material.

Many other valuable works are obtainable which treat of rag paper manufacture and the stories they tell are instructive as well as interesting.
