Charles Newbold
Charles Newbold was an American blacksmith born in 1780 in Chesterfield Township, 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.
On 1 April 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.
