Company origins

Charles H. Holt arrived in San Francisco from Concord, New Hampshire

, in 1864 to form C. H. Holt and Co. Initially the company produced wooden wheels for wagons and, later on, steel wheels for streetcars. In 1869, at age 20, his younger brother Benjamin went to work in their father's sawmill in New Hampshire along with William Harrison Holt and Ames Frank Holt, preparing hardwood

s for shipping to Charles in San Francisco. William and Ames joined Charles in San Francisco in 1871.

In the same year, Charles and Ames established the Holt Brothers Company in San Francisco. The company sold hardwood, lumber, and wagon and carriage materials, primarily manufacturing wagon axles, wheels, and frames. W. Harrison Holt and Ames both temporarily returned around 1871 to New Hampshire – where both were married – to manage the eastern business. The brothers built a factory in Concord, New Hampshire, to manufacture wagon wheels, wheel components, bodies and running gear. In 1872, at age 23, Benjamin was given an interest in his father's business, and he assumed more responsibility for the company's operations. W. Harrison Holt moved to Tiffin, Ohio

, to manage the company's lumber business there, where he remained until the early 1880s. Their mother died in 1875, and their father died eight years later in 1883. After his father's death, Benjamin Holt left New Hampshire in 1883 to help Charles build the business in California.

Charles, Benjamin and Frank incorporated the Holt Bros. Company on January 7, 1892, to deal in lumber and iron. Four days later, they also filed incorporation papers for "Holt Manufacturing Company" with Charles H. Holt, Benjamin Holt, Frank A. Holt, G. H. Cowie and G. L. Dickenson as directors.

The Holt Bros. Company formed a subsidiary, the "The Stockton Wheel Company", to build the wheels. They based their company in the warm Central Valley town of Stockton, California

Farm equipment and tractors

In the late 19th century, there were a large number of companies across the world striving to build a practical horse-drawn combine harvester
Combine harvester

 and other farm equipment. They soon moved on inventing steam-powered farm machinery and, later, designs for crawler-type tractors. More than 100 patents were issued for various crawler designs. Holt began manufacturing horse-drawn combine harvesters in the 1890s and converted to steam-power types around the turn of the 20th century. Over the next few years Benjamin Holt designed and manufactured the first successful crawler-type tractor and designed a gasoline engine (see Tractor design, below.)

Pliny Holt wrote a letter to the Stockton management team on July 1, 1909, reporting, "The plant is as complete and perfect in every detail as I have ever seen ... and one of the best arranged plants that I ever saw."

On October 25, 1909, Pliny Holt purchased the factory, and immediately began preparing the plant for operations with 12 employees.

s during World War I and their capabilities and reliability had become well-known. Benjamin Holt also gained valuable experience securing government contracts. These capabilities separated him from his competition. Holt had obtained significant loans and begun a large expansion to meet the war planners' need for his tractors.

 had meanwhile concentrated on supplying the market for smaller agricultural tractors. Although Best did not make tractors for the war effort, they had secured promises from the federal government that they would be able to obtain all the steel required to continue building tractors for farmers during the war. As a result, Best had gained a considerable market advantage over Holt by war's end. Best also assumed considerable debt to allow it to continue expansion, especially production of its new Best Model 60 "Tracklayer".

When the war ended, Holt's planned expansion to meet the military's needs was no longer needed. The company was left in a difficult situation. The types of tractors needed by the military were very different from what farmers needed. Their situation was worsened as artillery tractors were brought back from Europe, depressing prices for new equipment and Holt's unsold inventory of military tractors. The company moved to focus less on agricultural machinery and more on producing road-building equipment. To keep the company afloat, they borrowed heavily.

Both companies were affected by the transition from a wartime to a peacetime economy, which contributed to a nationwide depression, further inhibiting sales.

On December 5, 1920, 71-year-old Benjamin Holt died after a month-long illness. Holt had been considered a "quiet and unassuming man who loved his work". He was well liked by his workers and dedicated a trust fund for employees who suffered financial difficulties.

Caterpillar company formed

The banks who held the company's large debt forced the Holt board of directors to accept their candidate, Thomas A. Baxter, to succeed Benjamin Holt. Baxter was a former Boston banker who had joined the Holt company in 1913 as a business manager. The company struggled with the transition from wartime boom to peacetime bust. Baxter initially cut the large tractors from the company's product line and introduced smaller models focused on the agricultural market. When the Federal Aid Highway Act of 1921

 company.

Between 1907 and 1918, Best and Holt had spent about USD$1.5 million in legal fees fighting each other. The two companies competed economically and intellectually: Benjamin Holt had 47 patents in his name, while his nephew Pliny Holt had 38 patents; Best founder Daniel Best received 42 patents and his son C. L. Best had 27 patents.

Harry H. Fair of the bond brokerage house of Pierce, Fair & Company of San Francisco was involved in funding C. L. Best's debt, when Holt shareholders approached him about their company's financial plight. He concluded that both companies might not survive and recommended that the Holt and Best companies should consolidate operations. In April and May 1925, the financially stronger C. L. Best merged with the market leader Holt Caterpillar to form the Caterpillar Tractor Co.

  Baxter had been removed as CEO earlier in 1925, and Clarence Leo Best assumed the title of CEO, and remained in that role until October, 1951. The new company was headquartered in San Leandro until 1930, when under the terms of the merger it was moved to Peoria.

The Caterpillar company consolidated its product lines, offering only five track-type tractors: the 2 Ton, 5 Ton, and 10 Ton from the Holt Manufacturing Company's old product line and the and from the C. L. Best Tractor Co.'s former product line. The 10 Ton and 5 Ton models were discontinued in 1926. In 1928, the 2 Ton was discontinued. The first completely new tractor produced after the union of the two companies was the 1929 Caterpillar L20.

After Benjamin Holt's death in 1920, William K. "Bill" Holt formed the first Caterpillar dealership in Mexico. In 1933, he was authorized to operate the dealership for the 60 southern counties of Texas. The company merged with another Holt business and was renamed HOLT CAT. It continues as the largest Caterpillar dealerships in the United States.

In comparison, large modern combines have a 20 feet (6.1 m) cutting bar. Some of the Holt combines needed as many as 40 horses to operate.

Holt adapted the combine to work on slopes. He added two separate wooden frames which enabled the drive wheels to be raised or lowered independently. This allowed the combine to operate on slopes as steep as 30 degrees while the threshing machine remained level. In 1890, Holt built his first experimental steam traction engine

. Holt tried to solve the problem by increasing the size and width of the wheels, but this also made the tractors increasingly complex, expensive and difficult to maintain. One tractor had wheels 7.5 feet (2.3 m) tall and 6 feet (1.8 m) wide, producing a tractor 46 feet (14 m) wide. Holt could spend hours in his private workshop, and experimented by adding multiple wheels and ultimately with a track-laying technique.

First workable crawling tread

Many people had attempted to add tracks to moving machines. Over 100 patents had already been issued worldwide, but all failed to work in practical situations. In 1903 Benjamin Holt paid Alvin Lombard USD$60,000 for the right to produce vehicles under Lombard's patent for the Lombard Steam Log Hauler

, was experimenting with a chain-track. Hornsby's design incorporated a steering clutch that varied the speed of each set of wheels, allowing the operator to turn the tractor by retarding one tread or the other. Roberts of Hornsby & Sons obtained a patent for their design in July 1904.

By December 1903, Holt wielded considerable influence over former competitors, including Houser-Haines Manufacturing and Mattison-Williamson Works.

Holt returned to Stockton and applied his skills and his company's expertise in metallurgy, design, and testing to develop a workable track-laying system. He replaced the wheels on a 40 hp 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!" Others reported that Holt got the name from British troops who witnessed a working prototype of Hornsby's track-type vehicle in July 1907. Continuous tracks allowed practical cultivation of the rich farmland on an industrial scale. The invention also allowed planters to reclaim thousands of acres of delta land previously unusable for farming.

Holt began producing models under the Caterpillar brand. His first production model had a dual-track frame 30 inches (76.2 cm) high by 42 inches (106.7 cm) wide by 9 feet (2.7 m) long. Its tracks used 3 by 4 in (7.6 by 10.2 ) slats made of the same redwood

 used previously to produce wagon wheels. Holt sold the first model of steam-powered tractor crawlers for USD$5,500. By 1915, the Holt company employed 1,000 workers in its Stockton plant. Nearly 2,000 Caterpillar crawlers had been sold in more than 20 countries.

Gasoline engines

Pliny E. Holt, the son of Benjamin's half-brother, William Harrison Holt, had been working with Stockton Wheel Company for the past nine years. In 1906, he was named president of the newly formed Aurora Engine Company, named after Aurora Street in Stockton where it was located. The new company manufactured gasoline engines to replace the large, heavy steam boilers used to power the earlier Holt tractors. A gasoline engine considerably reduced the overall size and weight of a tractor, produced more power per pound of weight, and reduced the tractor's cost, making it more cost-effective and affordable. Holt's most popular gasoline engine tractor was a Model 75, weighing 24000 lbs with a 75 hp engine. Pliny was also treasurer of another subsidiary, the Houser and Haines Manufacturing Company of Stockton, from 1905-09.

, a gasoline-engined tractor required fewer men to operate it. Competing steam engines typically required a crew of seven, including one highly skilled and well-paid, licensed "farm engineer". He was responsible for rising in the middle of the night to start the boiler fire to get up steam by first light. Steam traction boilers had a huge need for water and fuel, either coal or wood. Much of the seven-man crew's time was spent keeping it fueled.

Tiller wheel

C. L. Best introduced a crawler tractor in 1913 that was virtually a carbon copy of Holt's design. Holt's tractors had a conventional wheel on the front, which was used to steer, and crawling-type wheels on the back, but otherwise looked very similar to a traction engine

. During 1914, both Best and Holt introduced models without the front "tiller" or steering wheel. Holt offered the Caterpillar 45 and Best introduced his C. L. Best Model 40 "Tracklayer".

Patents and trademark disputes

Benjamin Holt aggressively defended his patents and was quick to sue anyone he felt might infringing on his rights. In June 1899, he claimed that the Haines-Houser's tractors used certain devices for which Holt held the trademark. Holt sent all farmers who owned Haines-Houser tractors in Yolo County, California

 lawsuit ensued between the two. After three years of legal battles, the two companies decided to settle out of court. The parties resolved two suits when Holt made a cash payment to C. L. Best and provided C. L. Best a license giving them access to all Holt patents applying to manufacturing the C. L. Best's "Tracklayers." In 1916, C. L. Best bought his father's old factory in San Leandro, which Holt had closed after acquiring the company. C. L. Best built a new factory on the same location. His company gained attention for its continued improvements to its products.

Holt buys Lombard patent

Holt received a patent 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 1908, he designed a gasoline engine to power the tractor.

Although Holt had paid Alvin Orlando Lombard USD$20,000 in 1903 (about $ today) for rights to use his patents, Lombard visited Holt in 1910 complaining of patent infringement

, and when Lombard raised the issue of money, Holt merely suggested that they divide the country. Lombard should take up the Northern woods and Holt would take the remainder of the nation. Holt promised to write a letter to that effect, although he never did.

Best invalidates Lombard patent

In 1915, the C. L. Best Gas Traction Co. exhibited its new "Tracklayer" at the California state fair. Holt once again sued, this time for patent infringement

. C. L. Best thought that his best defense was to prove that Holt's patents violated Lombard's patents. One of Best's lawyers, Henry Montgomery, visited Lombard and sought his assistance as a friendly witness. Lombard was more than friendly. He allegedly responded, "By God, young man, I'm glad to see you. If God Almighty could charter me to kill a man, I'd get on the train and go to California and kill old Ben Holt." Best bought all rights to Lombard's 1901 and 1907 patents for $20,000, which pre-dated Holt's "crawler" patents also purchased from Lombard. Holt's earlier rights to the Lombard patents were annulled and Best counter-sued Holt.

s and he registered "Caterpillar" as a trademark in 1911. Since Holt had trademarked Caterpillar, Best named his tractors Tracklayers. In 1911, Holt began building the "Holt Model 60 Caterpillar" in its Stockton plant and a "Holt Model 40-60 Caterpillar" at its East Peoria factory. Additional models followed, including the "Holt Model 60-75 Caterpillar", which sold very well, eventually renamed as the "Holt Model 75 Caterpillar", their best-selling front tiller-wheeled tractor.

 because as owner of the Best Manufacturing Company, he believed he also owned the "Best" name. Holt did not prevail and Best continued to produce tractors that directly competed with Holt's models.

Holt continued to innovate and worked to build a tractor that could perform rugged tasks yet was not heavy itself. He fitted adjustable blades onto his tractors and hired them out to grade roads and move soil and rock for construction purposes. By 1916, Holt had sold over 2,000 tractors worldwide.

Early military uses

The concept of a half-wheeled, half-tracked vehicle appeared in the United States around 1916. The Holt company was one of the earliest manufacturers, which attached its crawling tread mechanism to an ordinary 4x2 truck of about three tons' capacity, replacing the rear drive axle.

Hauled artillery and supplies

The Allies used crawler tractors to replace horses for hauling artillery and other supplies. The full advantages of a track-laying vehicle appear not to have been realized until they were used in the quagmire of Northern France. The tracks allowed it to negotiate terrain that was impassable to horse teams and wheeled vehicles. The Quartermaster Corps also used them to haul long trains of freight wagons over the unimproved dirt tracks behind the front. However, the Holt tractor really proved its usefulness when in October 1917, Britain and France each sent six divisions to assist the Italians. The Holt tractor ferried the supplies and ammunition over the steep and twisting mountain roads in less than two weeks.

Additional prototypes were produced, including the "Mark II" and "Mark III", and the "Mark IV", which departed slightly from the prior models. Pliny completed a preliminary study of a one-man tank which was later built by the Ford company. The prototypes were rejected after trials found that their size and maneuverability did not offer the relative agility required by a tank for cross-country travel.
Holt also produced the world's first self-propelled artillery, a 75mm gun that could travel at 28 miles per hour (12.5 m/s), exceeding the military requirement of 12 miles per hour (5.4 m/s), and climb a 45 degree slope. Before the work could be completed, the Armistice
