International expansion: 1925–1949

Cargill becomes international, and diversifies outside of the grain trade

Still largely a regional grain trader, Cargill grew steadily throughout the 1930s and 40s and established offices in Canada, Holland, and Argentina. The company weathered the financial turmoil of the 1930s, as well as a major legal battle with the Chicago Board of Trade. It introduced new innovations to the industry, including a teletype wire system, a new style of grain terminal (first constructed in Omaha, Nebraska), and the establishment of a grain laboratory. Many of these innovations originated directly from Cargill's new leader, John MacMillan, Jr. By the 1940s, Cargill had diversified into feed, soybean processing, seed and vegetable oil.
