Famous people, CanadaCharles Fenerty
Charles Fenerty is a Canadian inventor who invented the wood pulp process for papermaking which was first adapted into the production of newsprint.

Charles was born in 1821 in Nova Scotia, Canada. He and his two brothers grew up on the family’s large farm near Sackville. His father owned three old-fashioned sawmills. Charles spent much of his spare time there and he had the opportunity to learn a great deal about wood and wood fibers. At the age of 17 he began his experiments of making paper from wood (that time paper was made from pulped rags). In 1844 he made his discovery. Since he was only in his late teens, the idea of patenting his invention never crossed his mind. He neglected to patent his invention and others did patentpapermaking processes based on wood fiber. Pulped wood paper slowly began to be adopted by paper mills throughout Canada, the U.S. and Europe. German newspapers were the first to adopt the process, by the end of the 19th-century almost all newspapers in the western world were using pulp wood newsprint.

There is no record of Fenerty having invented anything else in his lifetime; also his life seems to have been eventful in other ways. He was a poet, a farmer, a tax collector, a health warden, an Australian miner
