About Cyrus McCormick: Founder of the McCormick Harvesting Machine Company

Cyrus Hall McCormick (February 15, 1809 to May 13, 1884) was an American inventor and businessman who founded the McCormick Harvesting Machine Company, which became part of the International Harvester Company in 1902. Originally from the Blue Ridge Mountains of Virginia, he and many members of the McCormick family became prominent residents of Chicago. McCormick always claimed credit as the single inventor of the mechanical reaper, though he was one of several designing engineers who produced working models in the 1830s. His efforts built on more than two decades of work by his father, Robert McCormick Jr., with the aid of Jo Anderson, an enslaved African-American man held by the family. He also successfully developed a company, with manufacturing, marketing and a sales force, to market his products. He was born in Raphine, Virginia, the eldest of eight children of the inventor Robert McCormick Jr. and Mary Ann "Polly" Hall. Seeing the potential of the design for a mechanical reaper, his father applied for a patent to claim it as his own invention, having worked for 28 years on a horse-drawn mechanical reaper.
