In 1915, a lawyer named Henry Montgomery traveled to Maine to meet with Alvin Orlando Lombard, a blacksmith from Waterville who had built the first commercially successful tracked vehicle in America. Montgomery represented C. L. Best, who was locked in a legal war with the Holt Manufacturing Company, and he was looking for patent ammunition to use against Holt.

Lombard, who had been nursing a grudge for years, unleashed his fury. He told Montgomery that if God Almighty would charter him to kill a man, he would get on the next train to California and kill old Ben Holt. The animosity ran deep. Eleven years earlier, in 1903, Benjamin Holt had paid Lombard $60,000 for the right to build crawler tractors under Lombard’s patent.

That arrangement had gone sour, and the resulting three-way war between Holt, Lombard, and the Best family would burn through $1. 5 million in legal fees before it was over. The crawler track did not begin with one genius and one invention. It began with a broken promise, a stolen patent, and a rivalry that would shape the construction industry for a century.

This is how Caterpillar was really built. To understand how it all came to pass, one must go back to a sawmill in Concord, New Hampshire, where the man who would create the most recognized name in construction history never made a single engineering drawing in his life. He designed everything in his head. Benjamin Leroy Holt was born on January 1st, 1849, the youngest of four brothers among eleven children.

His father, William Knox Holt, owned a sawmill that produced hardwood for wagon and coach construction. Benjamin trained as a wheelwright in that mill, with no formal engineering education. Everything he knew about machines, he learned by building them and tearing them apart. The four brothers who would matter to this story were William Harrison, the oldest, born around 1840; Ames Frank, born around 1842; Charles Henry, born in 1843; and Benjamin, six years younger than his nearest brother.

Charles was the first to leave New Hampshire. In 1863, at the height of the Civil War, he traveled to San Francisco and opened a lumber and wagon wheel business called C. H. Holt and Company.

William and Ames followed in 1871. Benjamin stayed behind, running the sawmill alone and shipping lumber west to his brothers. He stayed for twelve more years, through his mother Harriet’s death in 1875 and his father William Knox’s death in 1883. Only after burying both parents did Benjamin finally head to California at the age of 34.

The reason the Holts chose Stockton was not about agriculture. It was about wood. Charles Holt had discovered that wagon wheels manufactured from eastern hardwood cracked and failed in California’s arid climate because the wood had not been properly seasoned for dry conditions. Stockton’s hot inland climate was perfect for drying lumber.

The city also sat on the San Joaquin River, reachable by ocean-going ships 72 miles from San Francisco, and the Central Pacific Railroad had arrived in 1869. It was an inland seaport at the heart of California’s richest wheat-growing region. In 1883, Stockton had roughly 7,500 residents. Founded during the Gold Rush in 1849, it had been the fourth largest city in California by 1854.

By the time the Holts arrived, the economy had shifted from gold supply depot to agricultural hub, with flour mills, carriage factories, iron foundries, and shipyards. Five other agricultural machinery companies already operated there. Benjamin invested $65,000, roughly $2. 5 million today, in a factory at the corner of Church and Aurora Streets.

He powered the entire operation with a single 40-horsepower Corliss steam engine manufactured in Providence, Rhode Island, and shipped all the way around Cape Horn to California. Every machine in the plant was belt-driven from that one engine. He started with 25 employees. First year output was 6,000 wagon wheels and 5,000 carriage bodies.

Their most popular product was 10-foot diameter wheels used by redwood loggers, who connected two wheels with a strong axle and used horse teams to drag massive logs from roadless forests. Everyone in Stockton knew Benjamin as Uncle Ben. He spent his mornings in a private workshop across from the main Holt office building that his employees called the little shop of invention. It had machine tools, a pattern shop, and about six dedicated workers.

In the afternoons, he would sit in town talking with friends. He was called the Edison of the West after developing the side-hill combine harvester, a machine that operated on slopes up to 30 degrees while keeping its threshing mechanisms level. It was 36 feet wide and required more than 20 horses to pull it. The detail that matters most for understanding how the crawler track was born is this: Benjamin Holt never made engineering drawings.

He designed everything in his head and told his pattern makers and machinists verbally how to build things. The only drawings that existed were rough sketches for casting patterns. He was, as his colleagues described him, the old-style engineer who worked from an idea in his head. His two closest collaborators were Henry Preble and E.

J. Patterson. When absorbed in a problem, he forgot meals, became oblivious to conversation, and responded to questions with an occasional grunt. In 1890, Benjamin married Anna Brown in Stockton.

She was 19 years younger than him, the daughter of prominent Stockton pioneer Benjamin Eseck Brown, and the marriage plugged Holt directly into the local establishment. They had five children. Anna would serve as regent of the University of the Pacific for 25 years and outlived Benjamin by 32 years, dying in 1952. The Holt Manufacturing Company was formally incorporated on January 11th, 1892.

By that point, the factory had expanded from 25 employees to nearly 200. The original three-story brick building had been joined by additional wood-frame structures, a foundry, and a dedicated machine shop. They were producing not just wagon wheels, but complete freight wagons, spring wagons, and drays for the agricultural trade. Annual output was climbing toward half a million dollars.

Within a few years of arriving in Stockton, the Holts had moved into combine harvesters. Benjamin developed a link-belt system that used flexible chains instead of gears. When runaway horses pulled a harvester too fast, the belts would break rather than destroying expensive gear trains. A Holt combined harvester from 1886 is still held by the Smithsonian Institution in Washington.

By 1916, Holt combines would harvest 90 percent of all grain produced on the Pacific Coast. But the real problem that would define Benjamin Holt’s legacy was not grain. It was mud. The Sacramento-San Joaquin River Delta, west of Stockton, comprised 250 square miles of peat bogs, much of it below sea level.

This former seabed had accumulated deep organic peat soil over thousands of years. The soil was incredibly fertile for farming, but it was catastrophically soft for machinery. A man walking through the worst areas would sink to his knees. Even horses fitted with wide wooden shoes called tule shoes to spread their weight could not operate in many sections.

And the heavy steam traction engines of the 1890s, which weighed roughly 1,000 pounds for every horsepower they produced, would sink to the axle and become completely immobile. Thousands of acres of prime farmland were effectively useless because no machine could plow them. Holt’s first steam traction engine, a machine nicknamed Old Betsy, came off the line in 1890. It weighed 48,000 pounds on a 24-foot frame, produced 60 horsepower from a single cylinder with an 11-inch diameter bore and a 12-inch stroke, carried 675 gallons of water, and could burn wood, coal, or oil.

On firm ground, it hauled 50 tons at 3 miles per hour and could harvest at one-sixth the cost of horse-drawn combines. On peat soil, it buried itself. Holt tried the obvious solution first. He made the wheels bigger.

He mounted three enormous drive wheels on each side of a steam engine, each one 6 feet wide and 7. 5 feet tall. The single front steering wheel was replaced with a 10-foot wide wooden barrel. The result was a machine with 18 feet of drive wheels sticking out on each side, creating a total width approaching 46 feet.

It looked, as one observer described it, like a cross between a locomotive and a giant rolling pin. It could not pass through gates. It could not cross bridges. It could not turn at the end of a field.

And despite those massive wheels, it still sank into the peat soil. Getting it out reportedly required every horse and mule in the San Joaquin Valley. Benjamin Holt was not the first person to think of putting a continuous track on a vehicle. He was not the second.

He was not even the 50th. Over 100 patents for crawler-type vehicle treads had already been issued worldwide before Holt’s famous test. Every single one had failed in the field. The lineage stretched back centuries.

In 1713, a Frenchman named De Armand drew a goat-pulled cart riding on 26 rollers wrapped in a belt. In 1770, an Englishman tried powering a similar vehicle with steam. It failed. In 1825, Sir George Cayley patented a universal railway, but with no provision for steering.

In 1832, John Heathcoat built a 30-ton steam plowing engine on two belts, each 7 feet wide. It sank into a swamp and nearly disappeared entirely. In 1858, a man named Warren P. Miller demonstrated a tracked steam plow at the California State Fair in Sacramento, won a cash prize and a gold medal, but only one unit was ever built because he ran out of money.

In 1869, George Minnis broke sod near Ames, Iowa, with a tracked steam engine. In 1871, R. C. Parvin demonstrated a crawler steamer at the Illinois State Fair, started a company, and the company promptly failed.

Every attempt, every decade, every country, failure after failure after failure for nearly two centuries. Holt studied this entire lineage. In 1903, he traveled to England specifically to observe tracked vehicle experiments. He saw multiple designs.

They all failed field tests, but he returned to Stockton with critical knowledge. And more importantly, with something none of the previous inventors had possessed. His company had spent 20 years manufacturing link-belt chains for combine harvesters. That specific metallurgical and chain manufacturing capability would prove to be the difference between another failed crawler patent and the machine that would change the world.

On Thanksgiving Day, November 24th, 1904, Holt’s engineers rolled out a modified steam traction engine at the company’s test grounds near Stockton. Engine number 77, a Holt Junior road engine rated at 40 horsepower, had its rear drive wheels removed and replaced with tracks Benjamin had designed in his head and described verbally to his machinists. Each track frame measured 30 inches high by 42 inches wide by 9 feet long. The track shoes were 3 by 4-inch redwood planks bolted to endless malleable link chains, the same chains Holt had been perfecting for 20 years on his combine harvesters.

Power was transmitted through sprocket wheels. The machine’s weight rode on rollers sitting on top of the lower chain loop. The test location was spongy peat soil beside Mormon Slough, just outside Stockton. The machine crawled forward across ground that had defeated every wheeled tractor ever built.

It then traveled back along Aurora Street to the factory. Extended testing followed on Roberts Island in the Delta and on the Holt ranch itself. The results were decisive. That 40-horsepower tracked machine pulled four two-bottom plows.

A 60-horsepower wheeled Holt steamer could only pull three. The tracked engine plowed 2 inches deeper at 2 to 3 miles per hour. On Roberts Island, where a man could not walk without sinking to his knees, the tracked traction engine operated without leaving a perceptible impression in the ground. Between 1904 and 1906, Holt fabricated six steam-powered track-type prototypes.

The first production model sold in late 1906 for $5,500, roughly $185,000 today. It went to Louisiana for reclaiming wetlands to grow sugarcane. In 1908, Holt made another critical leap. He designed a gasoline engine to replace steam power in his crawlers.

He was so worried that his stockholders would reject the investment, thinking gasoline was a passing fad, that he created a separate subsidiary called the Aurora Engine Company specifically to hide the expenditure from the board. Within 2 years, over 100 gasoline-powered crawlers were in service. Now, the name. Everyone knows the word caterpillar, but almost nobody knows that Benjamin Holt did not like it.

The standard telling places the naming at the Thanksgiving 1904 test. The real timeline is different. The name was most likely coined in March of 1905 during a separate photo session, not during the first test. Company photographer Charles Clements left a first-person account preserved in Caterpillar’s own archives.

He described riding out to the Holt ranch near Roberts Island and seeing the tracked machine moving across a barley field. In his account, he jumped to his feet and exclaimed that it looked like a monster caterpillar. Other versions of the story exist. Some attribute the remark to a man named John Shepherd, who was also present.

One source attributes it to William Mulholland, the famous Los Angeles water engineer, watching a Holt demonstration for the Los Angeles Aqueduct project. A separate British claim holds that soldiers coined the word watching a Hornsby tracked tractor at the military grounds at Aldershot in 1907. What Caterpillar’s own website confirms is this: Benjamin Holt did not like the name caterpillar at all. His family, particularly his nephew Pliny Holt, persuaded him it was the logical choice.

Before that name stuck, the machine had been called a platform wheel engine, a mud turtle, a paddle wheel, and a treadmill. The caterpillar name first appeared on a tractor in 1909. It was formally trademarked on August 2nd, 1910. Holt claimed use dating back to 1904.

He received US patent 874,008 for his traction engine on December 17th, 1907, and he held 47 patents over his lifetime. His nephew Pliny held an additional 38. The crawler’s first major proving ground beyond the Delta came in 1908 when the Los Angeles Aqueduct project purchased a Holt Model 70-120 tractor to haul supplies across the Mojave Desert. The 233-mile aqueduct was being built to carry water from the Owens Valley to Los Angeles, and the machine hauled 30 tons up a 14 percent grade without difficulty.

Engineers immediately ordered 25 more tractors and 78 specially designed Holt wagons. In total, 32 of the first 100 Holt Caterpillar track-type tractors ever manufactured went to work on this single project. Loads weighed up to 50 tons traveling at 4 miles per hour through deep sand and grades of 10 to 30 percent. One section demonstrated that 14 Caterpillar tractors hauled materials over 26,000 miles at 20 cents per ton mile, compared to 40 to 80 cents per ton mile for animal teams.

But even as the machines were proving themselves in the California desert, the legal war was escalating. Alvin Orlando Lombard was born in 1856 in Waterville, Maine. He built the first commercially successful tracked vehicle, the Lombard steam log hauler, and he patented it on May 21st, 1901, US patent 674,737. That patent was a full 3 years before Holt’s Thanksgiving Day test.

Lombard’s prototype, nicknamed Mary Ann, was first tested on Thanksgiving Day, 1900, exactly 4 years before Holt’s famous demonstration. The Lombard was a half-track vehicle with rear continuous tracks and front steering skis, designed for hauling logs over snow. It weighed 19 to 20 tons and could haul 300 tons of timber. 83 units were built between 1901 and 1917.

In 1903, Holt paid Lombard $60,000 for the right to produce vehicles under Lombard’s patent. This gave Holt legal cover for his own crawler development. Then came the betrayal. In 1910, Lombard traveled to California to confront Holt about what he saw as ongoing patent infringement.

Holt’s expensive lawyers had concluded that Lombard’s patents had little value due to prior art. Holt took Lombard on a leisurely country drive in his Oldsmobile roadster, casually suggested they divide the country between them, with Lombard taking the northern woods and Holt taking everything else, and promised to write a letter confirming the arrangement. He never wrote that letter. Lombard’s fury festered for years.

When C. L. Best’s lawyer, Henry Montgomery, visited Lombard in 1915 seeking patent ammunition to use against Holt, Lombard made his murderous declaration. Best purchased two of Lombard’s most important patents, used them to defeat Holt in court, and then sold the Lombard patent rights back to Holt at a profit.

That money helped get Best’s competing company on its feet. Meanwhile, Holt purchased the crawler track patents held by the British firm Richard Hornsby and Sons of Grantham, England for £4,000. Hornsby’s chief engineer, David Roberts, had filed British patent 16,345 on July 23rd, 1904, practically simultaneous with Holt’s own work. Roberts demonstrated tracked tractors to the British War Office multiple times between 1904 and 1910, and even to King Edward VII at Aldershot in 1908.

He also fitted a 75-horsepower Mercedes car with tracks that reached 25 miles per hour on the beach at Skegness, a tracked vehicle speed record that was not surpassed until World War II. Despite all of this, Hornsby sold only five machines in total. The British military was simply not interested in buying them from a British manufacturer. Holt was reportedly more interested in their differential steering mechanism than in the track system itself.

The ironic consequence was that within a year of purchasing those patents, Holt sold 442 continuous track tractors to the British Army, many of them built under license by Ruston and Hornsby in Lincoln, England. Britain had to buy American-made crawlers based partly on their own citizen’s patent. And then, there was Daniel Best. Born in 1838 in Ohio, Best held 42 patents of his own, had lost three fingers in a sawmill accident, and once staged one of the great publicity stunts in agricultural history.

In 1893, his gasoline engine hauled a rival steam engine around the block in a tug-of-war. In 1908, at the age of 70, Daniel Best retired and sold his company to Holt for $325,000, roughly $11. 6 million today. His son, Clarence Leo Best, known as C.

L. Best, received one-third interest and was made president of the Holt-controlled entity. But C. L.

felt his authority was being systematically undermined. An internal Holt memo boasted that the acquisition would make them so strong that they could crush outside competition. By 1910, C. L.

resigned, forfeiting an estimated $50,000 in interest, and founded the C. L. Best Gas Traction Company. He built a 30,000-square-foot plant on 10 acres near San Leandro, California.

Holt immediately sued for breach of contract and trademark infringement. Holt lost. By 1912, Best was producing tracked machines virtually identical to Holt’s design and deliberately using the word caterpillar in his advertising. It was a calculated provocation.

His Best 75 won the gold medal at the California State Fair in 1913. That same year, Holt closed the San Leandro plant he had acquired from Daniel Best. A suspicious fire destroyed a building that housed the models of Daniel Best’s patent machines. It was supposedly a fireproof masonry building.

A family member later speculated arson. In 1916, C. L. Best bought back his father’s old San Leandro factory for $30,000, partly funded by a community fundraiser where local residents contributed $14,000 of their own money.

He opened a new 60,000-square-foot plant with 200 workers earning a combined $17,000 per month in payroll. The total legal fees between the two companies from 1905 to the mid-1920s reached approximately $1. 5 million, roughly $27. 5 million in today’s money.

Holt’s trademark tagline during this period was simple: “There is only one caterpillar and Holt builds it. ” Best, barred from using caterpillar, branded his machines tracklayers. And all of this was happening while Benjamin Holt was losing his entire family. Ames Frank Holt died in October 1889.

William Harrison Holt died on February 15th, 1904, just 9 months before the Thanksgiving Day test that changed everything. Charles Henry Holt died on July 8th, 1905, while on a trip to Spokane, Washington, only 7 months after the crawler track had proven itself. By 1905, Benjamin was the last brother standing, completely alone at the helm, right as the caterpillar revolution was taking off. The most important invention in construction history was developed by a man who was burying his brothers one by one as he built it.

Then came the war. In August 1914, World War I erupted across Europe, and Benjamin Holt’s California farm tractor became the most important piece of military equipment on the Western Front. The connection began not in Washington or London, but in Hungary. In 1910, a wealthy Hungarian farmer named Leo Steiner ordered a Holt tractor, became a dealer with exclusive rights for Austria-Hungary and Germany, and by 1913 was purchasing as many Holts as possible for the Austro-Hungarian military.

When war broke out, Holt refused to fill those orders. The key figure who connected Holt to the British tank program was a mining engineer named Hugh F. Marriott. He had seen a Holt caterpillar in Antwerp, Belgium in July 1914 and wrote to Colonel Ernest Swinton with a simple assessment: “This machine climbs like hell.

” Swinton forgot that letter until October 1914 when driving through northern France as a war correspondent, he conceived the idea of an armored tracked fighting vehicle. By Christmas 1914, Swinton saw a Holt tractor towing a gun through the mud of Flanders, and the tank concept crystallized. Benjamin Holt’s tractors ended up powering the tank programs of all three sides of the war. The British Mark was inspired by Holt’s design, though the final machine was engineered from scratch by William Tritton and Lieutenant Walter Wilson at Winston Churchill’s Land Ships Committee, founded on February 20th, 1915 with £70,000 in Admiralty funds.

They tested actual Holt tractors, but found them insufficient for crossing trenches. The French Schneider CA1 was built directly on a lengthened Holt baby chassis. France ordered 400 Schneider tanks at 56,000 francs each. At the training base at Marly-le-Roi, crews trained on actual Holt tractors because the Schneider tanks were not ready yet.

And the German A7V, the only German-designed tank of the war, had running gear directly copied from captured Holt tractors provided by the Austro-Hungarian Army. Only 20 were ever completed as tanks. One man’s invention, all three sides. The entire mechanized warfare revolution of the 20th century traces back to a factory in Stockton, California.

Holt manufactured over 5,000 tractors during the war. An estimated 10,000 Holt vehicles served in the Allied effort when including license-built units produced by Ruston and Hornsby in England and by Maxwell, REO, and Chandler Motor Companies in the United States. The British alone purchased over 1,800 Holt 75 tractors and 243 Holt 120 models. Total wartime government contracts exceeded $23 million.

Pliny Holt stated in September 1916 that they had been shipping two caterpillars per day to the British government for the previous 18 months. All motors were manufactured in Stockton. They were assembled at their Peoria plant and shipped as agricultural machinery. Holt also attempted to build actual tanks, and the results were spectacular failures.

The Holt gas-electric tank, America’s first tank prototype, was a partnership with General Electric. It used a 90-horsepower Holt engine connected to a GE generator powering two electric motors. It weighed 25 tons, reached 6 miles per hour on flat ground, and could not climb slopes at all. It was tested and rejected at Aberdeen Proving Ground.

The Holt steam wheel tank used two 75-horsepower Doble steam engines built by Abner Doble, the famous steam car manufacturer. It had three wheels, two 8-foot rear wheels, and a front roller. It weighed 17 tons and repeatedly got stuck during testing. Only one prototype was ever built.

On April 22nd, 1918, General Ernest Swinton, the man credited as the father of the tank, visited Stockton to publicly honor Benjamin Holt. The city held a parade. Swinton called Holt the developer of the track that inspired the tank and said it helped change the course of the war. By the end of the war, nearly everything Holt had built was at risk.

Millions of dollars in government contracts were abruptly canceled after the armistice on November 11th, 1918. Nearly 10,000 surplus military tractors flooded the civilian market, collapsing new equipment prices practically overnight. A farmer who needed a crawler could now buy a surplus military Holt for a fraction of what a new one cost. Holt’s inventory of heavy military machines was poorly suited for farming.

The company had expanded aggressively during the war, growing from about 1,000 employees in 1915 to over 2,500 at peak production. They had built new factory buildings, hired specialists, and taken on debt to finance the expansion. When the contracts evaporated, the debt remained. Company assets had increased by more than $12 million during 1917 and 1918, but most of that was now worthless inventory.

And while Holt had focused on war production, C. L. Best had captured the domestic farm market. Best had secured government promises for all the steel needed to keep building farm tractors while Holt was shipping everything he had to Europe.

Best’s machines, particularly the Best 30 and Best 60, were lighter, more fuel-efficient, and better suited for agricultural work than Holt’s heavy military crawlers. Benjamin Holt was 71 years old and exhausted. He fell ill in November 1920. On his deathbed, one of his last requests was a progress report on a machine he had under development.

He died on December 5, 1920, leaving a company drowning in war expansion debt. Banks forced the board to accept Thomas F. Baxter, a former Boston banker, as Benjamin’s successor. Both Holt and Best were battered by the depression of 1920 and 1921.

A San Francisco bond broker named Harry H. Fair, who had financed Best’s debt and also had ties to Holt shareholders, concluded that both companies might not survive independently. On April 15, 1925, the two companies merged to form the Caterpillar Tractor Company. C.

L. Best, the financially stronger partner, became chairman and CEO, a position he held until his death in October 1951. Raymond C. Force became president.

Murray M. Baker, the implement dealer who had found the East Peoria plant for Pliny Holt back in 1909, became the first executive vice president. Initial headquarters were in San Leandro, California, but the merger terms required a move to Peoria, Illinois, which happened in 1930. What each side brought to the deal tells everything about how this rivalry ended.

Best contributed better finances, advanced tractor designs, and a strong dealer network focused on farming. Holt contributed worldwide reputation, the Caterpillar trademark, larger manufacturing facilities, and a 40-year combine harvester product line. The initial product line was consolidated to five track-type tractors. First-year sales were $13 million.

By 1929, they reached $52. 8 million. The old Holt plant in East Peoria, Illinois, which Pliny Holt had purchased in 1909 for just $50,000 when the facility had cost $450,000 to build, became the company’s largest manufacturing center. Machines were painted battleship gray with red trim until the iconic highway yellow with black trim was adopted in 1931.

C. L. Best himself said the merger would have never happened without the Caterpillar name. The name Benjamin Holt never wanted.

The Holt family never left the Caterpillar business. They just shifted from manufacturing to dealership. Benjamin’s son, William Knox Holt, moved to San Antonio, Texas, in 1933 and established William K. Holt Machinery Company, a Caterpillar dealership starting with one store and fewer than 10 employees.

In the 1940s, he developed the Holt root plow for clearing brush on the King Ranch using custom twin D8 Caterpillar tractors. Benjamin’s great-grandson, Peter M. Holt, served in Vietnam, where he earned a Silver Star, three Bronze Stars for Valor, and a Purple Heart. He later reunited the original Texas dealership and grew it from one of the smallest Caterpillar dealers in the country to the largest in the United States and one of the five largest in the world.

He set up headquarters in a corrugated metal building he nicknamed The Barn. In 1993, he invested in the NBA team, the San Antonio Spurs, to keep them in San Antonio. The Spurs won five NBA championships under Holt ownership. Today, fifth-generation descendants Peter John Holt and Corinna Holt Richter run Holt Cat across a Texas territory covering 118 counties.

That territory includes Holt Cat, Texas First Rentals, and Holt Truck Centers across 35 locations. Peter John Holt is now chairman and managing partner of the San Antonio Spurs. The direct line from Benjamin Holt’s 1883 wagon wheel shop to a modern billion-dollar equipment empire and NBA franchise spans 143 years and five generations. Caterpillar is today worth over $70 billion.

It employs more than 100,000 people in nearly every country on Earth. Every crawler track on every bulldozer, every tank, every piece of tracked equipment anywhere in the world traces its lineage to a 40-horsepower steam engine with redwood planks bolted to chains rolling across peat soil beside Mormon Slough on Thanksgiving Day, 1904. The man who built it never wanted the name. The man who really invented the crawler track wanted him dead.

And the rival whose company he tried to crush became the first CEO of the empire that carries his invention’s name. That is the real story of Benjamin Holt and the birth of Caterpillar.
