Charles Fenerty is a Canadian inventor who invented the wood pulp process for papeimaking 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 patent papermaking 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.

Automobile manufacturer Henry Ford was born the first of six children on 30th July, 1863 on the family's farm Dearborn, Michigan. He set off at the young age of sixteen to the nearby town of Detroit to work as a machinist's apprentice. Then he returned to his home in Dearborn and worked as a part-time employee for Westinghouse Engine Company.
Ford's marriage to Clara Bryant in 1888 required him to get a better paying job. In 1891 he started as an engineer for Edison Illuminating Company and was promptly promoted to Chief Engineer. The job required Ford to be on call 24 hours a day. In his on-call time he began to experiment with internal combustion engines and created the Quadricycle, the first "horseless carriage", powered by gasoline and riding on four bicycle wheels. This invention led to the founding of Ford Motor Company.
In 1903 with $28,000, eleven men, and Ford as Vice President and Chief Engineer, Ford Motor Company was incorporated. In 1908 the company produced the famous Model T, a reliable and affordable vehicle for the mass market (Henry Ford and his engineers used the first 19 letters of the alphabet to name their automobiles, although some of the cars were never sold to public). By 1918, half of all cars in the U.S. were a Model T.
Henry Ford died on 7lh April, 1947 and his presidency was passed down to his grandson Henry Ford II.
