Charles Newbold
American blacksmith
Charles Newbold (1764–1835) was an American blacksmith born in Chesterfield, New Jersey. On June 26, 1797, Newbold received the first patent for a cast-iron plow. However, he was unable to sell his plow because many farmers feared that the iron in it would poison the soil.[1]
On April 1, 1807, inventor David Peacock was issued a patent for a three-piece iron plow (Newbold's plow was cast in one piece). Newbold then sued Peacock for patent infringement and won $1500.
