Coda: Steam’s Last Stand

In the year 1900, automobile sales in the United States were divided almost evenly among three types of vehicles: automakers sold about 1,000 cars powered by internal combustion engines, but over 1,600 powered by steam engines, and almost as many by batteries and electric motors. Throughout all of living memory (at least until the very recent rise of electric vehicles), the car and the combustion engine have gone hand in hand, inseparable. Yet, in 1900, this type claimed the smallest share.

For historians of technology, this is the most tantalizing fact in the history of the automobile, perhaps the most tantalizing fact in the history of the industrial age. It suggests a multiverse of possibility, a garden of forking, ghostly might-have-beens. It suggests that, perhaps, had this unstable equilibrium tipped in a different direction, many of the negative externalities of the automobile age—smog, the acceleration of global warming, suburban sprawl—might have been averted. It invites the question, why did combustion win? Many books and articles, by both amateur and professional historians, have been written to attempt to answer this question.

However, since the electric car, interesting as its history certainly is, has little to tell us about the age of steam, we will consider here a narrower question—why did steam lose? The steam car was an inflection point where steam power, for so long an engine driving technological progress forward, instead yielded the right-of-way to a brash newcomer. Steam began to look like relic of the past, reduced to watching from the shoulder as the future rushed by. For two centuries, steam strode confidently into one new domain after another: mines, factories, steamboats, railroads, steamships, electricity. Why did it falter at the steam car, after such a promising start?

The Emergence of the Steam Car

Though Germany had given birth to experimental automobiles in the 1880s, the motor car first took off as successful industry in France. Even Benz, the one German maker to see any success in the early 1890s, sold the majority of its cars and motor-tricycles to French buyers. This was in large part due to the excellent quality of French cross-country roads – though mostly gravel rather than asphalt, they were financed by taxes and overseen by civil engineers, and well above the typical European or American standard of the time. These roads

…made it easier for businessmen [in France] to envisage a substantial market for cars… They inspired early producers to publicize their cars by intercity demonstrations and races. And they made cars more practical for residents of rural areas and small towns.[1]

 The first successful motor car business arose in Paris, in the early 1890s. Émile Levassor and René Panhard (both graduates of the École centrale des arts et manufactures, an engineering institute in Paris), met as managers at a machine shop that made woodworking and metal-working tools. They became the leading partners of the firm and took it into auto making after becoming licensors for the Daimler engine.

Before making cars themselves, they looked for other buyers for their licensed engines, which led them to a bicycle maker near the Swiss border, Peugeot Frères Aînés, headed by Armand Peugeot. Though bicycles seem very far removed from cars today, they made many contributions to the early growth of the auto industry. The 1880s bicycle boom (stimulated by the invention of the chain-driven “safety” bicycle) seeded expertise in the construction of high-speed road vehicles with ball bearings and tubular metal frames. Many early cars resembled bicycles with an additional wheel or two, and chain drives for powering the rear wheels remained popular throughout the first few decades of automobile development. Cycling groups also became very effective lobbyists for the construction of smooth cross-country roads on which to ride their machines, literally paving the way for the cars to come.[2]

Armand Peugeot decided to purchase Daimler engines from Panhard et Levassor and make cars himself. So, already by 1890 there were two French firms making cars with combustion engines. But French designers had not altogether neglected the possibility of running steam vehicles on ordinary roads. In fact, before ever ordering a Daimler engine, Peugeot had worked on a steam tricycle with the man who would prove to be the most persistent partisan of steam cars in France, Léon Serpollet.

A steam-powered road vehicle was not, by 1890, a novel idea. It had been proposed countless times, even before the rise of steam locomotives: James Watt himself had first developed an interest in engines, all the way back in the 1750s, after his friend John Robison suggested building a steam carriage. But those who had tried to put the idea into practice had always found the result wanting. Among the problems were the bulk and weight of the engine and all its paraphernalia (boiler, furnace, coal), the difficulty of maintaining a stoked furnace and controlling steam levels (including preventing the risk of boiler explosion), and the complexity of operating the engine. The only kinds of steam road vehicles to find any success, were those that inherently required a lot of weight, bulk, and specialized training to operate—fire engines and steamrollers—and even those only appeared in the second half of the nineteenth century.[3]

Consider Serpollet’s immediate predecessor in steam carriage building, the debauched playboy Comte Albert de Dion. He commissioned two toymakers, George Bouton and Charles Trépardoux to make several small steam cars in the 1880s. These coal-fueled machines took thirty minutes or more to build up a head of steam. In 1894 a larger Dion steam tractor finished first in one of the many cross-country auto races that had begun to spring up to help carmakers promote their vehicles. But the judges disqualified Dion’s vehicle on account of its impracticality: requiring both a driver and a stoker for its furnace, it was in a very literal sense a road locomotive. A discouraged Comte de Dion gave up the steam business, but De Dion-Bouton went on to be a successful maker of combustion automobiles and automobile engines.[4]

Coincidentally enough, Léon Serpollet and his brother Henri were, like Panhard and Levassor, makers of woodworking machines, and like Peugeot, they came from the Swiss borderlands in East-central France. Also like Panhard and Levassor, Léon studied engineering in Paris, in his case at the Conservatoire national des arts et métiers. But by the time he reached Paris, he and his brother had already concocted the invention that would lead them to the steam car: a “flash” boiler that instantly turned water to steam by passing it through a hot metal tube. This would allow the vehicle to start more quickly (though it still took time to heat the tube before the boiler could be used) and also alleviate safety concerns about a boiler explosion.

The most important step to the (relative) success of the Serpollets’ vehicles, however, was when they replaced the traditional coal furnace with a burner for liquid, petroleum-based fuel. This went a long way towards removing the most disqualifying objections to the practicality of steam cars. Kerosene or gasoline weighed less and took up less space than an energy-equivalent amount of coal, and an operator could more easily throttle a liquid-fuel burner (by supplying it with more or less fuel) to control the level of steam.

With early investments from Peugeot and a later infusion of cash from Frank Gardner, an American with a mining fortune, the Serpollets built a business, first selling steam buses in Paris, then turning to small cars. Their steam powerplants generated more power than the combustion vehicles of the time, and Léon promoted them by setting speed records. In 1902, he surpassed seventy-five miles-per-hour along the promenade in Nice. At that time, a Gardner-Serpollet factory in eastern Paris was turning out about 100 cars per year. Though impressive numbers by the standards of the 1890s, already this was becoming small potatoes. In 1901 7,600 cars were produced in France, and 14,000 in 1903; the growing market left Gardner-Serpollet behind as a niche producer. Léon Serpollet made one last pivot back to buses, then died of cancer in 1907 at age forty-eight. The French steam car did not survive him.[5]

Unlike in the U.S., steam car sales barely took off in France, and never had parity with the total sales of combustion engine cars from the likes of Panhard et Levassor, Peugeot, and many other makes. There was no moment of balance when it appeared that the future of automotive technology was up for grabs. Why this difference? We’ll have more to say about that later, after we consider the American side of the story.

The Acme of the Steam Car

Automobile production in the United States lagged roughly five years behind France; and so it was in 1896 that the first small manufacturers began to appear. Charles and George Duryea (bicycle makers, again), were first off the block. Inspired by an article about Benz’ car, they built their own combustion-engine machine in 1893, and, after winning several races, they began selling vehicles commercially out of Peoria, Illinois in 1896. Several other competitors quickly followed.[6]

Steam car manufacturing came slightly later, with the Whitney Motor Wagon Company and the Stanley brothers, both in the Boston area. The Stanleys, twins named Francis and Freelan (or F.E. and F.O.), were successful manufacturers of photographic dry plates, which used a dry emulsion that could be stored indefinitely before use, unlike earlier “wet” plates. They fell into the automobile business by accident, in a similar way to many others—by successfully demonstrating a car they had constructed as a hobby, drawing attention and orders. At an exhibition at the Charles River Park Velodrome in Cambridge, F.E. zipped around the field and up an eighty-foot ramp, demonstrating greater speed and power than any other vehicle present, including an imported combustion-engine De Dion tricycle, which could only climb the ramp halfway.[7]

The rights to the Stanley design, through a complex series of business details, ended up in possession of Amzi Barber, the “Asphalt King,” who used tar from Trinidad’s Pitch Lake to pave several square miles worth of roads across the U.S.[8] It was Barber automobiles, sold under the Locomobile brand, that formed the plurality of the 1,600 steam cars sold in the U.S. in 1900: the company sold 5,000 total between 1899 and 1902, at the quite-reasonable price of $600. Locomobiles were quiet and smooth in operation, produced little smoke or odor (though they did breathe great clouds of steam), had the torque required to accelerate rapidly and climb hills, and could smoothly accelerate by simply increasing the speed of the piston, without any shifting of gears. The rattling, smoky, single-cylinder engines of their combustion-powered competitors had none of these qualities.[9]

Why then, did the steam car market begin to collapse after 1902? Twenty-seven makes of steam car first appeared in the U.S. in 1899 or 1900, mostly concentrated (like the Locomobile) in the Northeast—New York, Pennsylvania, and (especially) Massachusetts. Of those, only twelve continued making steam cars beyond 1902, and only one—the Lane Motor Vehicle Company of Poughkeepsie, New York—lasted beyond 1905. By that year, the Madison Square Garden car show had 219 combustion models on display, as compared to only twenty electric and nine steam.[10]

Barber, the Asphalt King, was interested in cars, regardless of what made them go. As the market shifted to combustion, so did he, abandoning steam at the height of his own sales in 1902. But the Stanleys loved their steamers. Their contractual obligations to Barber being discharged in 1901, they went back into business on their own. One of the longest lasting holdouts, Stanley sold cars well into the 1920s (even after the death of Francis in a car accident in 1918), and the name became synonymous with steam. For that reason, one might be tempted to ascribe the death of the steam car to some individual failing of the Stanleys: “Yankee Tinkerers,” they remained committed to craft manufacturing and did not adopt the mass-production “Fordist” methods of Detroit. Already wealthy from their dry plate business, they did not commit themselves fully to the automobile, allowing themselves to be distracted by other hobbies, such as building a hotel in Colorado so that people could film scary movies there.[11]

But, as we have seen, there were dozens of steam car makers, just as there were dozens of makers of combustion cars; no idiosyncrasies of the Stanley psychology or business model can explain the entire market’s shift from one form of power train to another—if anything it was the peculiar psychology of the Stanleys that kept them making steam cars at all, rather than doing the sensible thing and shifting to combustion. Nor did the powers that be put their finger on the scale to favor combustion engines.[12] How, then, can we explain both the precipitous rise of steam in the U.S. (as opposed to its poor showing in France) as well as its sudden fall?

The steam car’s defects were as obvious as its advantages. Most annoying was the requirement to build up a head of steam before you could go anywhere: this took about ten minutes for the Locomobile. Whether starting or going, the controls were complex to manage. Scientific American described the “quite simple” steps required to get a Serpollet car going:

A small quantity of alcohol is used to heat the burner, which takes about five minutes; then by the small pump a pressure is made in the oil tank and the cock opened to the burner, which lights up with a blue flame, and the boiler is heated up in two or three minutes. The conductor places the clutch in the middle position, which disconnects the motor from the vehicle and regulates the motor to the starting position, then puts his foot on the admission pedal, starting the motor with the least pressure and heating the cylinders, the oil and water feed working but slightly. When the cylinders are heated, which takes but a few strokes of the piston, the clutch is thrown on the full or wean speed and the feed-pumps placed at a maximum, continuing to feed by hand until the vehicle reaches a certain speed by the automatic feed, which is then regulated as desired.[13]

Starting a combustion car of that era also required procedures long-since streamlined away—cranking the engine to life, adjusting the carburetor choke and spark plug timing—but even at the time most writers considered steamers more challenging to operate. Part of the problem was that the boilers were intentionally small (to allow them to build steam quickly and reduce the risk of explosion), which meant lots of hands-on management to keep the steam level just right. Nor had the essential thermodynamic facts changed – internal combustion, operating over a larger temperature gradient, was more efficient than steam. The Model T could drive fifteen to twenty miles on a gallon of fuel, the Stanley could go only ten, not to mention its constant thirst for water, which added another “fueling” requirement.[14]

The steam car overcame these disadvantages to achieve its early success in the U.S. because of the delayed start of the automobile industry there. American steam car makers, starting later, skipped straight to petroleum-fueled burners, bypassing all the frustrations of dealing with a traditional coal-fueled firebox, and banishing all associations between that cumbersome appliance and the steam car.

At the same time, combustion automobile builders in the U.S. were still early in their learning curve compared to those in France. A combustion engine was a more complex and temperamental machine than a steam engine, and it took time to learn how to build them well, time that gave steam (and electric) cars a chance to find a market. The builders of combustion engines, as they learned from experience, rapidly improved their designs, while steam cars improved relatively little year over year.

Most importantly, they never could get up and running as quickly as a combustion engine. In one of those ironies which history graciously provides to the historian, the very impatience that the steam age had brough forth doomed its final progeny, the steam car. It wasn’t possible to start up a steam car and immediately drive; you always had to wait for the car to be ready. And so drivers turned to the easier, more convenient alternative, to the frustration of steam enthusiasts, who complained of “[t]his strange impatience which is the peculiar quirk of the motorist, who for some reason always has been in a hurry and always has expected everything to happen immediately.”[15] Later Stanleys offered a pilot light that could be kept burning to maintain steam, but “persuading motorists, already apprehensive about the safety of boilers, to keep a pilot light burning all night in the garage proved a hard sell.”[16] It was too late, anyway. The combustion-driven automotive industry had achieved critical mass.

The Afterlife of the Steam Car

The Ford Model T of 1908 is the most obvious signpost for the mass-market success of the combustion car. But for the moment that steam was left in the dust, we can look much earlier, to the Oldsmobile “curved dash,” which first appeared in 1901 and reached its peak in 1903, when 4,000 were produced, three times the total output of all steam car makers in that pivotal year of 1900. Ransom Olds, son of a blacksmith, grew up in Lansing, Michigan, and caught the automobile bug as a young man in 1887. Like many contemporaries, he built steamers at first (the easier option), but after driving a Daimler car at the 1893 Chicago World’s Fair, he got hooked on combustion. His Curved Dash (officially the Model R) still derived from the old-fashioned “horseless carriage” style of design, not yet having adopted the forward engine compartment that was already common in Europe by that time. It had a modest single-cylinder, five-horsepower engine tucked under the seats, and an equally modest top speed of twenty miles-per-hour. But it was convenient and inexpensive enough to outpace all of the steamers in sales.[17]

The market for steam cars was reduced to driving enthusiasts, who celebrated its near-silent operation (excepting the hiss of the burner), the responsiveness of its low-end torque, and its smooth acceleration without any need for clunky gear-shifting. (There is another irony in the fact that late-twentieth century driving enthusiasts, disgusted by the laziness of automatic transmissions, would celebrate the hands-on responsiveness of manual shifters.) The steam partisan was offended by the unnecessary complexity of the combustion automobile. They liked to point out how few moving parts the steam car had.[18] To imagine the triumph of steam is to imagine a world in which the car remained an expensive hobby for this type of car enthusiast.

Several entrepreneurs tried to revive the steamer over the years, most notably the Doble brothers, who brought their steam car enterprise to Detroit in 1915, intent on competing head-to-head with combustion. They strove to make a car that was as convenient as possible to use, with a condenser to conserve water, key-start ignition, simplified controls, and a very fast-starting boiler.

But, meanwhile, car builders were steadily scratching off all of the advantages of steam within the framework of the combustion car. Steam cars, like electric cars, did not require the strenuous physical effort to get running that early, crank-started combustion engines did. But by the second decade of the twentieth century, car makers solved this problem by putting a tiny electric car powertrain (battery and motor) inside every combustion vehicle, to bootstrap the starting of the engine. Steam cars offered a smoother, quieter ride than the early combustion rattletraps, but more precisely machined, multi-cylinder engines with anti-knock fuel canceled out this advantage (the severe downsides of lead as an anti-knock agent were not widely recognized until much later). Steam cars could accelerate smoothly without the need to shift gears, but then car makers created automatic transmissions. In the 1970s, several books advocated a return to the lower-emissions burners of steam cars for environmental reasons, but then car makers adopted the catalytic converter.[19]

It’s not that a steam car was impossible, but that it was unnecessary. Every year more and more knowledge and capital flowed into the combustion status quo, the cost of switching increased, and no sufficiently convincing reason to do so ever appeared. The failure of the steam car was not due to accident, not due to conspiracy, and certainly not due to any individual failure of the Stanleys, but due to the expansion of auto sales to people who cared more about getting somewhere than about the machine that got them there. Impatient people, born, ironically, of the steam age.
