(born Feb. 15, 1809, Rockbridge county, Va., U.S. — died May 13, 1884, Chicago, Ill.) U.S. industrialist and inventor. He is generally credited with the development (from 1831) of the mechanical reaper, which revolutionized the harvesting of grain. By 1850 the McCormick reaper was known throughout the U.S.; its prizes and honours, including the Grand Medal of Honour at the 1855 Paris exposition, made it famous around the world. In 1902 the McCormick Harvesting Co. joined with other companies to form International Harvester Co., with McCormick's son Cyrus, Jr., as its first president.
