title: Cyrus McCormick text: Cyrus McCormick Cyrus Hall McCormick (February 15, 1809 – May 13, 1884) was an American inventor and businessman who founded the McCormick Harvesting Machine Company, which later became part of the International Harvester Company in 1902. From the Blue Ridge Mountains of Virginia, he and many members of his family became prominent residents of Chicago. McCormick has been simplistically credited as the single inventor of the mechanical reaper. However, he was one of several designing engineers who produced successful models in the 1830s. His efforts built on more than two decades of work by his father Robert McCormick Jr., as title: Cyrus McCormick text: other living man." The Wisconsin Historical Society holds Cyrus McCormick's papers.

His efforts built on more than title: Reaper text: McCormick in 1834 as a horse-drawn farm implement to cut small grain crops. This McCormick reaper machine had several special elements: Cyrus McCormick claimed that his reaper was actually invented in 1831, giving him the true claim to the general design of the machine. Over the next few decades the Hussey and McCormick reapers would compete with each other in the marketplace, despite being quite similar. By the 1850's, the original patents of both Hussey and McCormick had expired and many other manufacturers put similar machines on the market. In 1861, the United States Patent and Trademark Office issued a title: Reaper text: Made in Baltimore, Maryland, Hussey's design was a major improvement in reaping efficiency. The new reaper only required two horses working in a non-strenuous manner, a man to work the machine, and another person to drive. In addition, the Hussey Reaper left an even and clean surface after its use. The "McCormick Reaper" was designed by Robert McCormick in Walnut Grove, Virginia. However, Robert became frustrated when he was unable to perfect his new device. His son Cyrus asked for permission to try to complete his father's project. With permission granted, the McCormick Reaper was patented by his son Cyrus title: Cyrus McCormick Farm text: where meat was dried and smoked to preserve it through the winter. Refrigeration was not introduced until the late 19th century. The McCormick family also maintained a school on their property for neighboring children. The McCormick Farm at Walnut Grove is known as the birthplace of the mechanical reaper, the predecessor to the combine harvester. Cyrus McCormick reportedly designed, built, and tested his reaper all within six weeks at Walnut Grove, although the design may have been merely an improvement upon the similar device developed by his father and his brother Leander over 20 years.
