Caterpillar Inc. traces its origins to the 1925 merger of the Holt Manufacturing Company and the C. L. Best Tractor Company, creating a new entity, the California based Caterpillar Tractor Company. In 1986, the company re-organized itself as a Delaware corporation under the current name, Caterpillar Inc. Caterpillar's headquarters are located in Peoria, Illinois, United States.
In the late 1890s and early 1900s, competitors Daniel Best and Benjamin Holt individually experimented with ways to improve the traction of steam tractors used in farming California's Central Valley.
The steam tractors of the 1890s and early 1900s were extremely heavy, sometimes weighing 1,000 pounds (450 kg) per horsepower, and often sank into the rich, soft earth of the San Joaquin Valley Delta farmland surrounding Stockton, California. Benjamin Holt attempted to fix the problem by increasing the size and width of the wheels up to 7.5 feet (2.3 m) tall and 6 feet (1.8 m) wide, producing a tractor 46 feet (14 m) wide. But this also made the tractors increasingly complex, expensive and difficult to maintain.
Another solution considered was to lay a temporary plank road ahead of the steam tractor, but this was time-consuming, expensive, and interfered with earthmoving. Holt thought of wrapping the planks around the wheels. He replaced the wheels on a 40 horsepower (30 kW) Holt steamer, No. 77, with a set of wooden tracks bolted to chains. On Thanksgiving Day, November 24, 1904, he successfully tested the updated machine plowing the soggy delta land of Roberts Island. Company photographer Charles Clements was reported to have observed that the tractor crawled like a caterpillar, and Holt seized on the metaphor. "Caterpillar it is. That's the name for it!" Some sources, though, attribute this name to British soldiers in July 1907. Two years later Holt sold his first steam-powered tractor crawlers for US$5,500. Each side featured a track frame measured 30 inches (760 mm) high by 42 inches (1,100 mm) wide and were 9 feet (2.7 m) long. The tracks were 3 inches (76 mm) by 4 inches (100 mm) redwood slats.
Holt received the first patent for a practical continuous track for use with a tractor on December 7, 1907 for his improved "Traction Engine" ("improvement in vehicles, and especially of the traction engine class; and included endless traveling platform supports upon which the engine is carried").
In February 16, 1910, Holt opened up a plant in East Peoria, Illinois, led by his nephew Pliny Holt. There Pliny met farm implement dealer Murray Baker who knew of an empty factory that had been recently built to manufacture farm implements and steam traction engines. Baker, who later became the first executive vice president of what became Caterpillar Tractor Company, wrote to Holt headquarters in Stockton and described the plant of the bankrupt Colean Manufacturing Co. of East Peoria, Illinois. On October 25, 1909, Pliny Holt purchased the factory, and immediately began operations with 12 employees. Holt incorporated it as the Holt Caterpillar Company, although he did not trademark the name Caterpillar until August 2, 1910.
The addition of a plant in the Midwest, despite the hefty capital needed to retool the plant, proved so profitable that only two years later the company employed 625 people and was exporting tractors to Argentina, Canada, and Mexico. Tractors were built in both Stockton and East Peoria. Holt's track-type tractors play a support role in World War I. Even before the U.S. formally entered WWI, Holt had shipped 1,200 tractors to England, France and Russia for agricultural purposes. These governments, however, sent the tractors directly to the battlefront where the military put them to work hauling artillery and supplies. When World War I broke out, the British War Office ordered a Holt tractor and put it through trials at Aldershot. The War Office was suitably impressed and chose it as a gun-tractor. Over the next four years, the Holt tractor became a major artillery tractor, mainly used to haul medium guns like the 6-inch howitzer, the 60-pounder, and later the 9.2-inch howitzer. Holt tractors were also the inspiration for the development of the British tank, which profoundly altered ground warfare tactics. Major Ernest Swinton, sent to France as an army war correspondent, very soon saw the potential of a track-laying tractor.:116 Although the British later chose an English firm to build its first tanks, the Holt tractor became "one of the most important military vehicles of all time."
