The Genesis and Pioneering Spirit of Yellow Cab
The roots of the Yellow Cab Company stretch back to 1905 when Walden W. Shaw and John Hertz formed an automotive agency. A year later, the Walden W. Shaw company was incorporated, swiftly moving into the nascent taxi business by purchasing Thomas taxicabs equipped with meters in 1907. However, the true turning point arrived on New Year's Eve, 1914, with the completion of the design for the first purpose-built taxi by the Yellow Cab Manufacturing company.
This innovative vehicle, the Model J, hit Chicago streets in August 1915, replacing a diverse fleet of 12 different auto makes previously used. The company's ambition was clear: volume business. They aggressively reduced fares, at one point in 1915 and 1916 offering rides for just 25 cents for the first half-mile and 10 cents for each subsequent mile. These rates fluctuated over the years, mirroring the nation's economic shifts, with a mile ride costing 30-45 cents in the 1920s, dipping to 20 cents during the Great Depression in 1933, and rising to 60-70 cents by 1965.
Beyond pricing, Yellow Cab was a true pioneer. Robert E. Samuels, then president of the company, proudly recalled their many 'firsts'. A distinctive colour for cabs was one of their most impactful contributions. Yellow was chosen based on a research institute's survey, proving to be highly visible and memorable. But their innovations didn't stop there. Yellow Cab was at the forefront of adopting balloon tyres for a smoother ride, automatic windshield wipers, and ultra-high-frequency two-way radios for efficient dispatching. In later years, they also championed the fleet-wide use of passenger seat belts, showcasing a commitment to both service and safety.
The Emergence of Checker Taxi: A Different Model
By the mid-1920s, Yellow Cab had largely outmanoeuvred most of its competitors. However, a formidable rival emerged in 1919: the Checker Cab Company. Founded by Frank Dilger, an Oak Park, Illinois cabbie, Checker operated on a distinctly different model. Unlike Yellow Cab's centralised fleet, Checker was an association of independent owner-operators. These drivers, while owning their vehicles, operated under a single livery, easily identified by their striking green and cream paint scheme and distinctive logo. This decentralised model fostered a strong sense of independence and camaraderie among its drivers, setting the stage for an intense rivalry.
Chicago's Infamous Taxi Wars: A Violent Struggle for Dominance
The competition between the Yellow Cab Company and Checker Taxi was not merely economic; it escalated into a Taxi Wars that was fierce, frequently violent, and tragically resulted in numerous shootings and deaths. This period of extreme conflict peaked in 1920 and saw a resurgence in mid-1921, transforming Chicago's streets into a battleground.
Street Battles and Mobile Warfare
The violence began to grab headlines in July 1920, with reports of "Taxicabs Used as Tanks In Fierce Street Battle Between Rival Concerns." This wasn't hyperbole. Drivers from both companies engaged in what was described as "real mobile warfare." Yellow Cabs would rush past Checker headquarters, their occupants firing revolvers in broadsides. Checker cabs would retaliate en masse, launching counter-attacks with "shock action" tactics. Individual drivers, racing their cabs hub to hub, emptied pistols at close range. The battles often started from minor skirmishes, escalating rapidly into widespread engagements across the city, particularly on the West Side.
Police reports from these early clashes, surprisingly, often noted "no casualties," despite hundreds of shots being fired. However, this period served as a grim prelude to the more deadly confrontations that were to come.
Escalation and Fatalities: The Killing of P.A. Skirven
The violence reached a tragic new level on June 9, 1921, when P.A. Skirven, a Yellow Cab driver, was shot and killed. Police believed men connected with the Checker company were responsible. This single act ignited a firestorm, leading to at least four other shooting affrays that night, with passengers reportedly menaced by bullets. The Yellow Cab Company immediately offered a $5,000 reward for the arrest and conviction of Skirven's killers.
The president of the Yellow Cab Company, John Hertz, issued a chilling declaration of war: "We have gone just as far with the murderous methods of the Checker Taxi company as we intend to. It has only been comic opera, warfare until tonight, but from now on it is going to be a fight to a finish. We feel that we might just as well end the whole business right now." Hertz vowed to push for a grand jury investigation into Checker Cab's "entire crooked business," alleging that many Checker drivers were former Yellow Cab employees dismissed for "inefficiency, dishonesty, or worse," and thus harboured resentment.
Confessions, Arrests, and Political Intrigue
The very next day, Philip Fox, a Checker Cab chauffeur, confessed to his involvement in Skirven's murder, naming five companions. He admitted they had been "touring the city all night, doing all the damage they could to Yellow cabs." This confession came after the substantial reward offers from both companies (Yellow Cab's $5,000 and Checker's $25,000 for proof that the killers were Checker drivers). The subsequent arrests and legal proceedings highlighted the deep-seated animosity.
However, the conflict was not just between the companies; it quickly became entangled with Chicago's notoriously complex political landscape and unionism. Officials from Checker company alleged that "politics and unionism are back of the war," claiming they were "fighting the entire Thompson-Landin political organization." They accused the mayor and Chief of Police of unfair treatment, citing arbitrary arrests of Checker drivers for lacking cab stand licenses – a charge that had previously gone unpunished. Checker's attorney, Leonard J. Grossman, even claimed that Yellow Cab employed "gunmen and sluggers" and that a city policeman was on Yellow's payroll. This added a layer of corruption and political manipulation to an already violent feud.
Civic Intervention and Continued Violence
Alarmed by the escalating violence, Chicago aldermen George M. Mapole and Joseph O. Kostner introduced a resolution calling on the Chief of Police to keep both Yellow and Checker cabs off the streets until they could guarantee peace. Their primary concern was the safety of taxicab passengers, which they deemed "unsafe" in the prevailing climate. The proposal even included revoking licenses.
Despite these interventions, the violence sporadically flared up again. In April 1923, the "taxicab war broke anew" when Yellow Taxi Company superintendent J.S. Ringer was fired upon by men in a Checker taxi. Two years later, in July 1925, Mayor Dever himself issued a stern warning after an incident where a cab was burned and two others wrecked by a "bombardment of bricks." He declared, "The taxi drivers' war must stop, and stop immediately. We will see whether the taximen control and own the streets or the people." This incident was linked to disputes over exclusive rights to hotel taxi stands, revealing a broader pattern of conflict involving other smaller cab companies like Premier, De Luxe, and Diamond, all vying for lucrative passenger traffic.

The brutal nature of these taxi wars underscored the cut-throat competition of the era and the lengths to which companies and their employees would go to secure market share. It was a dark chapter in Chicago's transport history, reflecting a period of rapid urbanisation and often unregulated business expansion.
Beyond Cabs: Yellow Cab's Diversification and John Hertz's Empire
While the taxi wars raged, the Yellow Cab Manufacturing Co., under the ambitious leadership of John Hertz, was already looking beyond just taxis. On January 1, 1921, Hertz announced a massive expansion into the manufacture and distribution of passenger cars and light trucks. The company's new factory was set to produce thousands of vehicles, including the luxury 12-cylinder 'Ambassador' car, a more moderately priced 4-cylinder car based on the Yellow Cab chassis, and one-ton and one-and-a-quarter-ton speed-wagon trucks.
By 1925, Hertz had built a formidable business empire. The Yellow Cab Company itself was owned by the 'Chicago Yellow Cab Company', which was in turn controlled by Hertz, Parmelee, and other investors. In the same year, he established The Omnibus Corporation to control major public transport entities like the Chicago Motor Coach Company and the Fifth Avenue Coach Company in New York. His influence spanned across numerous companies:
- President of the Yellow Cab Company
- Chairman Benzoline Motor Fuel Company
- Chairman Chicago Motor Coach Company
- Chairman Fifth Avenue Coach Company
- Chairman New York Transportation Company
- Chairman Omnibus Corporation of America
- Chairman Yellow Coach Manufacturing Company
- Chairman Yellow Sleeve-Valve Engine Works
- Chairman Yellow Truck and Coach Manufacturing Company
Under Hertz's continued influence, the Yellow Cab operations continued to innovate, introducing further advancements like telephone dispatching of taxis. However, Hertz eventually sold his remaining interest in the Yellow Cab Company in 1929, reportedly following a traumatic firebombing of his stables, which resulted in the death of 11 horses – a stark reminder of the underlying ruthlessness that permeated even the highest levels of Chicago's business world.
The Legacy: What Happened to Yellow Cab and Checker Taxi?
The direct, violent confrontations between Yellow Cab and Checker Taxi largely subsided after the 1920s, as regulation increased and the industry matured. However, both companies continued to operate for many decades, their names becoming synonymous with Chicago's taxi service.
The Checker Taxi company, known for its distinctive vehicles, eventually became associated with the Checker Motors Corporation, which manufactured the iconic Checker Marathon taxi. While Checker Motors ceased car production in 1982, the Checker name continued to be used by independent taxi operators in Chicago and elsewhere. The "association of independent owner-operators" model that Checker pioneered proved resilient, allowing its brand to persist even as the manufacturing arm declined.
The Yellow Cab Company, on the other hand, continued its operations, albeit under various ownerships after John Hertz's divestment. The Yellow Cab name remains a widely recognised brand for taxi services across the United States, including in Chicago, even today. However, the original monolithic entity that Hertz built fragmented over time, with different Yellow Cab companies operating independently in various cities, often licensed franchises rather than direct descendants of the original Chicago powerhouse. The golden age of their direct, violent rivalry is long past, replaced by modern regulations and the rise of ride-sharing services.
The Hertz Corporation Connection
Perhaps one of the most enduring legacies of John Hertz's ventures, stemming indirectly from his Yellow Cab success, is the Hertz Corporation. In 1923, Hertz acquired a small car-rental operation in Chicago started by Walter L. Jacobs in 1918. This business, initially called Hertz Drive-Ur-Self System, was later acquired by General Motors Corporation in 1926 when GM bought Yellow Truck from John Hertz. The Hertz Corporation grew into a global car rental giant, and notably, still incorporates yellow into its logo today, a subtle nod to its founder's origins in the Yellow Cab Company.
