Charles Deering was an American businessman, art collector, and philanthropist. He was an executive of the agricultural machinery company founded by his father that became International Harvester. Charles's successful stewardship of the family firm left him with the means and leisure to indulge his interests in the arts and natural sciences. His activities and benefactions in the US were centered on Chicago and Miami; he also aspired to found an art museum in Spain.

The International Harvester Company was an American manufacturer of agricultural and construction equipment, automobiles, commercial trucks, lawn and garden products, household equipment, and more. It was formed from the 1902 merger of McCormick Harvesting Machine Company and Deering Harvester Company and three smaller manufacturers: Milwaukee; Plano; and Warder, Bushnell, and Glessner. Its brands included McCormick, Deering, and later McCormick-Deering, as well as International. Along with the Farmall and Cub Cadet tractors, International was also known for the Scout and Travelall vehicle nameplates. In the 1980s all divisions were sold off except for International Trucks, which changed its parent company name to Navistar International.
