A Scrap on the Stove
Sometime in the winter of 1839, in the small Massachusetts town of Woburn, a thin, sickly, deeply indebted man let a piece of rubber mixed with sulfur touch a hot stove. Every piece of rubber he had ever heated had melted into a stinking glue. This one charred at the edges, the way leather does, and around the char was a dry, springy rim that was still elastic. He nailed the scrap outside in the freezing air overnight. In the morning it was still flexible.
Charles Goodyear had been trying to make rubber usable for nearly five years by then, and he had already announced several false breakthroughs. His creditors, his relatives and most of the rubber trade regarded him as a crank. It would take him five more years to turn the scrap on the stove into a reliable manufacturing process, and he would patent it in 1844. The process, later called vulcanization, made rubber stable in heat and cold. It opened the way to waterproof clothing and footwear, industrial belts and hoses, insulation, medical goods and, decades after his death, the pneumatic tire.
Goodyear never profited in proportion to what he had made possible. He had been jailed for debt before the discovery and was jailed again after it, in Boston, in England and in Paris. He brought more than two hundred lawsuits against infringers and won the most famous of them, but spent much of what he earned on litigation, exhibitions and further experiments. When he died in 1860 he owed about $200,000. The largest rubber company in the world bears his name, but it was founded nearly four decades after his death by people who had no connection to him.
His story is often told as a parable of persistence rewarded by luck. It is better read as a study in two different skills: the patient, ingenious work of discovering something valuable, and the separate, unglamorous work of capturing the value. Goodyear mastered the first and never learned the second.

A Hardware Merchant from New Haven
Charles Goodyear was born in New Haven, Connecticut, on December 29, 1800, the eldest of six children of Amasa Goodyear and Cynthia Bateman Goodyear. The family traced its roots to Stephen Goodyear, one of the London merchants who founded the New Haven colony in 1638. Amasa was a hardware merchant and a minor inventor whose products included a steel hay fork, a lighter and stronger alternative to the cast-iron forks then common. In 1807 he moved the family to a farm near Naugatuck, Connecticut, where he had bought a water-powered factory that made buttons and farm tools.
Charles was a serious, religious boy who considered becoming a minister. At about seventeen he went instead to Philadelphia to learn the hardware trade. He later returned to Connecticut to work with his father. In August 1824 he married Clarissa Beecher, and two years later the young couple moved to Philadelphia, where Charles opened a hardware store selling the farm implements the family made. At a time when most such tools were imported from Britain, the store specialized in American-made goods, and for a while it did well.
The business did not last. Goodyear sold heavily on credit, fell seriously ill with dyspepsia around 1829, and saw the firm fail under the weight of its debts. Rather than take the relief of bankruptcy, he tried to repay his creditors over time. They lost patience, and in 1830 he was jailed for debt in Philadelphia. Over the following decade he would be imprisoned for debt repeatedly. He was thirty, with a growing family, a record of business failure and no obvious path forward.
Rubber Fever
In the early 1830s Americans had fallen briefly in love with rubber. The gum of South American trees was waterproof and elastic, and manufacturers began making it into coats, boots and life preservers. The Roxbury India Rubber Company of Massachusetts, generally described as the first American rubber manufacturer, led the way, and others quickly followed. The trouble was that raw rubber turned hard and brittle in cold weather and soft, sticky and foul-smelling in heat. Goods that looked fine when sold in winter came back as glue in summer.
In the summer of 1834 Goodyear, visiting New York, walked into the Roxbury company's retail store. According to the company's later account of the episode, he had noticed that the valve on its rubber life preservers was poorly made, designed a better one, and came back hoping to sell it. The manager told him that the company was in no position to buy anything. Its customers were returning melted goods by the thousand, and the directors, according to the same account, had quietly buried about $20,000 worth of rejects. The rubber boom was ending as quickly as it had started, and none of the early companies would last five years.
Goodyear left with the valve still in his pocket and an idea that would occupy the rest of his life. If someone could make rubber stable across the seasons, the market that had just collapsed would return, far larger than before. He had no training in chemistry and no money, but he had an unusual capacity for single-minded work, and rubber was cheap.
Experiments in Jail and Kitchen
When Goodyear returned to Philadelphia, a creditor had him jailed again. He began experimenting in his cell, working raw rubber by hand. His first idea was simple: if rubber was sticky, perhaps a dry powder could absorb the stickiness. He tried magnesia, a powder sold by druggists, and the results looked promising. Out of jail, he and his family made several hundred pairs of rubber overshoes in their kitchen, with magnesia worked into the gum. Before he could sell them, summer arrived and the shoes sagged into paste.
He moved to New York, where he worked in a borrowed attic room and walked to a mill in Greenwich Village to use its equipment. He tried boiling rubber with magnesia and quicklime, which produced a smoother, less sticky material. In 1835 he showed goods made this way at fairs held by New York's American Institute and Mechanics' Institute and won medals. Then he found that even a drop of weak acid destroyed the treatment. The "tanned" rubber, as he called it, was another dead end.
His next discovery came from an accident he almost missed. He liked to decorate his samples, and one day he used nitric acid to strip bronze paint from an old piece. The rubber turned black, and he threw it away. Days later, remembering that it had felt different, he retrieved it and found that the acid had given the surface a smooth, dry finish. He patented this "acid-gas" process on June 17, 1837, and even received a letter of commendation for his goods from President Andrew Jackson. The work was dangerous. Goodyear nearly suffocated from gas generated in his workroom and afterwards suffered a fever that almost killed him.
A New York businessman advanced several thousand dollars to begin production, and Goodyear set up a factory on Staten Island. Then the Panic of 1837 ruined his backer. The Goodyears, penniless again, camped in the abandoned factory, where, by the company's account, they lived for a time on fish he caught in the harbor.
Woburn and the Mailbags
Goodyear next found support in Boston from John Haskins, a former owner of the Roxbury company, and moved his family to Woburn, north of the city. He began making thin rubber goods such as tablecloths and piano covers. In Woburn he also met Nathaniel Hayward, the former foreman of the defunct Eagle India Rubber Company, who had been experimenting on his own. Hayward had found that rubber treated with sulfur and dried in the sun, a method he called "solarization," was much less sticky.
Goodyear recognized that Hayward was onto something. In 1838 he agreed to buy the rights to Hayward's process for $3,000, paid through a complicated mix of cash, a promissory note and a license, and hired Hayward as an employee. Hayward's patent, No. 1,090, was issued on February 24, 1839, with Goodyear named as assignee. It was a shrewd acquisition by a man who had almost nothing: he could not pay for it in cash, but he secured the most promising line of research in the field.
Hayward's role later became the subject of a local legend that he, not Goodyear, had discovered vulcanization. The record does not support it. Hayward's own patent describes mixing sulfur into rubber with solvents or by rolling, without the prolonged high heat that defines vulcanization. In a later affidavit, preserved in the Patent Office records of the 1850s, Hayward argued that his sulfur treatment was valuable on its own, since many goods could be made from it without being vulcanized, a claim that implicitly conceded the heat process was Goodyear's. The two men's contributions were different in kind. Hayward found an ingredient that improved rubber a little. Goodyear found the conditions under which that ingredient changed rubber completely.
Before the value of sulfur became clear, however, Goodyear suffered his most public failure. His partners won a federal government contract to make 150 rubber mailbags. Goodyear was confident enough in his goods that, according to one widely told account, he stored the finished bags in a warm room and left town. When he returned, the bags had melted. Sources differ on whether they were made with his nitric-acid process or with Hayward's sulfur treatment, but the effect was the same. His credit collapsed, his backers withdrew and his reputation as a man who could not deliver hardened. By the winter of 1838 to 1839 local farmers were letting his children dig half-grown potatoes from their fields.
The Prepared Mind
The discovery at the stove came in the middle of this collapse. The most common version, repeated by the Goodyear company in its own history, has him in a Woburn store in February 1839, waving a lump of his rubber-and-sulfur compound while arguing with skeptical townspeople, and accidentally flinging it onto a hot potbellied stove. Other versions place the event in his kitchen. Goodyear himself left the details vague.
He was firm, though, about what the moment meant. In his later book, he rejected the idea that he had simply been lucky. He compared the hot stove to Newton's falling apple: an event that carried meaning only for the person whose mind was prepared to draw the inference, the one who had applied himself most persistently to the subject. By 1839 he had spent five years mixing rubber with nearly every substance he could find. When the charred scrap stayed flexible, he was probably the only person in America who would have understood what he was looking at.
Understanding it was only the start. He now knew that heat and sulfur together transformed rubber, but not how much heat, for how long, or in what proportions. The next winter was, by his family's accounts, the worst of his life. Suffering from gout and dyspepsia, he moved about on crutches. He roasted rubber in hot sand, steamed it over a kettle, pressed it between hot irons and pushed samples into his wife's bread oven. He pawned his watch and the furniture. On a trip to Boston to look for backers he was jailed for an unpaid hotel bill of about five dollars, and he returned home to find that his infant son had died. Six of the Goodyears' twelve children died in infancy or early childhood.
Eventually he found that heating the compound with steam under pressure for several hours at around 270 degrees Fahrenheit gave the most consistent results. He had a process.
Shirred Goods and the Patent
What finally made the process commercial was a fashion. Goodyear wrote to his brother-in-law William De Forest, a New York woolen manufacturer who had once lectured him about neglecting his children, and explained that threads of cured rubber woven into cloth could produce the puckered, "shirred" effect then fashionable in shirts. De Forest was interested, and over the years his investment in Goodyear's work grew to nearly $50,000. Goodyear began making sheet goods in 1841, moved his main operations to a small factory in Springfield, Massachusetts, run largely by his brothers, and on March 9, 1844, patented a machine for making shirred rubber fabrics.
On June 15, 1844, he received U.S. Patent No. 3,633 for an "Improvement in India-Rubber Fabrics," the patent that covered vulcanization. That year the Naugatuck India-Rubber Company was established in Connecticut, the start of a rubber industry in the Naugatuck Valley that would last for more than a century. His brother Henry introduced mechanical mixing in place of solvents, and another brother, Nelson, later patented hard rubber for uses such as dentures.
Having finally reached the point where he could build a business, Goodyear largely chose not to. He disposed of his manufacturing interests and licensed his patents to other makers, product by product, then went back to inventing. He wanted to make everything from rubber: banknotes, musical instruments, ship sails, jewelry, even ships. He had his portrait painted on rubber and wore rubber hats and ties. Many of his ideas were decades ahead of their time. His licensing terms were far behind. According to the Goodyear company's history, the rights to shirred goods went for a royalty of three cents a yard on cloth that licensees sold for three dollars a yard.
Losing Britain
Goodyear had been slow to seek patents abroad, but he had not been slow to show off. In the early 1840s samples of his cured rubber, sent to potential British partners without an explanation of how they were made, reached England. One reached Thomas Hancock, a leading British rubber manufacturer and partner in Charles Macintosh and Company, who had been trying for years to solve the same problem. Hancock later said a friend, William Brockedon, had shown him American samples treated with sulfur in 1842. Whether or not he analyzed them, as critics later claimed, he worked out a vulcanization method of his own, involving immersion in molten sulfur, and filed a provisional British patent on November 21, 1843. Goodyear had not applied for one. It was Brockedon, by Hancock's account, who suggested the name "vulcanization," after Vulcan, the Roman god of fire.
When Goodyear finally sought British protection, he found Hancock already in place. According to the Goodyear company, Hancock offered him a half-share in the British patent if he would drop his challenge, and Goodyear refused. In 1855 Hancock's patent was contested in court by another British maker, Stephen Moulton, with the argument that Hancock had copied Goodyear. Goodyear attended the trial, hoping that if Hancock lost, his own British application would succeed. Several chemists testified that no one could have deduced the process from examining the samples. Hancock won, and Britain, then the world's largest manufacturing economy, was lost to Goodyear.
The Great India-Rubber Case
At home Goodyear fought infringers relentlessly. As soon as the 1844 patent was issued, rival manufacturers challenged it and others used the process without paying. Goodyear granted licenses to particular firms for particular products, secured a reissue of his patent that broadened its scope, and sued both unlicensed makers and licensees he believed were cheating him. A Yale Law Journal study of nineteenth-century patent litigation counts more than two hundred suits brought by Goodyear in the late 1840s and early 1850s.
The largest was against Horace H. Day, a New Jersey rubber manufacturer who had been one of Goodyear's most persistent adversaries. The case was argued in March 1852 before the federal circuit court at Trenton, New Jersey, with Justice Robert Grier of the Supreme Court and Judge Philemon Dickerson on the bench. The written proofs and exhibits ran to about 4,000 printed pages. Goodyear hired Daniel Webster, then secretary of state and the most celebrated advocate in the country, for a fee widely reported as $15,000, said to be the largest ever paid to an American lawyer at the time. Day was represented by Rufus Choate, one of Webster's few rivals at the bar. Webster, who died that October, spoke for two days.
On September 28, 1852, the court granted Goodyear a perpetual injunction against Day. The case became known as the Great India-Rubber Case, and legal historians regard Grier's decision as an important step toward deciding patent disputes in equity, before judges, without a jury. It made headlines and confirmed Goodyear's claim to be the inventor of vulcanization. It did not end infringement.
Palaces of Rubber
Goodyear's approach to publicity matched his approach to invention: total commitment regardless of cost. At the Great Exhibition in London in 1851, he built a Vulcanite Court, a suite of three rooms whose walls, roof, furniture, carpets and fittings were made of rubber, larger than the entire American section. It displayed combs, musical instruments, gloves, rafts and balloons, all of rubber. He borrowed heavily to pay for it.
In 1852 he went to Europe himself, in part to pursue his patent claims. His wife Clarissa, worn out by decades of hardship, died in England in 1853. That year he published Gum-Elastic and Its Varieties, a two-volume account of rubber, its uses and his own discovery, written in the third person. According to the Goodyear company, some copies were printed on and bound in rubber.
For the 1855 Exposition Universelle in Paris he built another elaborate rubber pavilion, again largely on credit. Then his French patent was canceled on a technicality, his French royalties stopped, and his creditors had him arrested. He spent sixteen days in the Clichy debtors' prison in Paris. While he was there, Emperor Napoleon III made him a knight of the Legion of Honour. By most accounts his son brought the medal to his cell. That same year he was also briefly jailed for debt in England.
In reflecting upon the past, as relates to these branches of industry, the writer is not disposed to repine, and say that he has planted, and others have gathered the fruits. The advantages of a career in life should not be estimated exclusively by the standard of dollars and cents, as is too often done. Man has just cause for regret when he sows and no one reaps.
— Charles Goodyear, Gum-Elastic and Its Varieties, 1853
The Extension and the End
Goodyear returned to the United States and, in 1858, applied for a seven-year extension of his vulcanization patent, which was due to expire after its original fourteen-year term. Extensions were granted when an inventor had not been reasonably paid for his work through no fault of his own. Goodyear showed that he had earned about $163,000 from the patent, a considerable sum, but that he owed far more to the creditors who had kept him alive while he developed it. Commissioner of Patents Joseph Holt granted the extension in June 1858 in a decision that read in places like a defense brief for the inventor.
No inventor probably has ever been so harassed, so trampled upon, so plundered by that sordid and licentious class of infringers known in the parlance of the world, with no exaggeration of phrase, as 'pirates.'
— Joseph Holt, U.S. Commissioner of Patents, Goodyear extension decision, 1858
The decision drew criticism as well as praise. Opponents of long patent monopolies campaigned against extensions for Goodyear and other inventors, and in 1861, a year after his death, Congress abolished the Patent Office's power to grant them. His heirs' later requests for renewal were refused.
By then Goodyear was an old man in his late fifties. For his last six years, gout and neuralgia had forced him to walk on crutches. He kept devising new uses for rubber. In the summer of 1860 he set out to visit a dying daughter in New Haven. When he reached New York he learned that she had already died. He collapsed and was taken to the Fifth Avenue Hotel, where he died on July 1, 1860, aged fifty-nine. He had never kept a proper accounting of his debts. His son Charles Goodyear Jr. untangled the books, paid off the creditors and secured a modest income for the family from the remaining royalties. The son had inherited his father's inventiveness and a better head for business: he developed shoemaking machinery, and the Goodyear welt, a method of attaching soles to shoes, is named after him.
An Industry Without Its Founder
By the year of Goodyear's death, the industry built on vulcanized rubber employed an estimated 60,000 people and produced goods worth more than $8 million a year. Rubber went on to become one of the essential materials of industrial society, in belting, hoses and seals, electrical insulation, medical products and, above all, tires. In 1898 Frank Seiberling founded a tire company in Akron, Ohio, and named it after the inventor. The Goodyear Tire and Rubber Company grew into the largest rubber business in the world. Neither Goodyear nor his family ever had any connection with it. In 1976 Goodyear was among the inventors inducted into the National Inventors Hall of Fame.
Later inventors such as
Thomas Edison learned to build organizations around their discoveries, with laboratories, financiers, manufacturing affiliates and lawyers working together. Goodyear worked almost alone. He solved a problem that had defeated the best-capitalized rubber firms of his day, through a combination of stubbornness, ingenuity and a willingness to endure poverty that his family paid for as much as he did. But he treated the business side of invention, including patents abroad, licensing terms, costs and accounts, as a distraction from the real work. The industry he created thrived, and it thrived without him.
