manufacturers bid against one another along the wharves for the gum which had been used as ballast and began to make rubber shoes.

European vessels had also carried rubber home; and experiments were being made with it in France and Britain. A Frenchman manufactured suspenders by cutting a native bottle into fine threads and running them through a narrow cloth web. And Macintosh, a chemist of Glasgow, inserted rubber treated with naphtha between thin pieces of cloth and evolved the garment that still bears his name.

At first the new business in rubber yielded profits. The cost of the raw material was infinitesimal; and there was a demand for the finished articles. In Roxbury, Massachusetts, a firm manufacturing patent leather treated raw rubber with turpentine and lampblack and spread it on cloth, in an effort to produce a waterproof leather. The process appeared to be a complete success, and a large capital was employed to make handsome shoes and clothing out of the new product and in opening shops in the large cities for their sale. Merchants throughout the country placed orders for these goods, which, as it happened, were made and shipped in winter.

But, when summer came, the huge profits of the manufacturers literally melted away, for the beautiful garments decomposed in the heat; and loads of them, melting and running together, were being returned to the factory. And they filled Roxbury with such noisome odors that they had to be taken out at dead of night and buried deep in the earth.

And not only did these rubber garments melt in the heat. It presently transpired that severe frost stiffened them to the rigidity of granite. Daniel Webster had had some experience in this matter himself. “A friend in New York,” he said, “sent me a very fine cloak of India Rubber, and a hat of the same material.

I did not succeed very well with them. I took the cloak one day and set it out in the cold. It stood very well by itself. I surmounted it with the hat, and many persons passing by supposed they saw, standing by the porch, the Farmer of Marshfield.”

It was in the year 1834, shortly after the Roxbury manufacturers had come to realize that their process was worthless and that their great fortune was only a mirage, and just before these facts became generally known, that Charles Goodyear made his entrance on the scene. He appeared first as a customer in the company’s store in New York and bought a rubber life-preserver.

When he returned some weeks later with a plan for improving the tube, the manager confided to him the sad tragedy of rubber, pointing out that no improvement in the manufactured articles would meet the difficulty, but that fame and fortune awaited the inventor of a process that would keep rubber dry and firm and flexible in all weathers.

Goodyear felt that he had a call from God. “He who directs the operations of the mind,” he wrote at a later date, “can turn it to the development of the properties of Nature in his own way, and at the time when they are specially needed. The creature imagines he is executing some plan of his own, while he is simply an instrument in the hands of his Maker for executing the divine purposes of beneficence to the race.” It was in the spirit of a crusader, consecrated to a particular service, that this man took up the problem of rubber. The words quoted are a fitting preface for the story of the years that followed, which is a tale of endurance and persistent activity under sufferings and disappointments such as are scarcely paralleled even in the pages of invention, darkened as they often are by poverty and defeat.

Charles Goodyear was born at New Haven, December 29, 1800, the son of Amasa Goodyear and descendant of Stephen Goodyear who was associated with Theophilus Eaton, the first governor of the Puritan colony of New Haven. It was natural that Charles should turn his mind to invention, as he did even when a boy; for his father, a pioneer in the manufacture of American hardware, was the inventor of a steel hayfork which replaced the heavy iron fork of prior days and lightened and expedited the labor of the fields. When Charles was seven his father moved to Naugatuck and manufactured the first pearl buttons made in America; during the War of 1812 the Goodyear factory supplied metal buttons to the Government. Charles, a studious, serious boy, was the close companion of his father. His deeply religious nature manifested itself early, and he joined the Congregational Church when he was sixteen. It was at first his intention to enter the ministry, which seemed to him to offer the most useful career of service, but, changing his mind, he went to Philadelphia to learn the hardware business and on coming of age was admitted to partnership in a firm established there by his father. The firm prospered for a time, but an injudicious extension of credit led to its suspension. So it happened that Goodyear in 1834, when he became interested in rubber, was an insolvent debtor, liable, under the laws of the time, to imprisonment. Soon afterward, indeed, he was lodged in the Debtor’s Prison in Philadelphia.

It would seem an inauspicious hour to begin a search which might lead him on in poverty for years and end nowhere. But, having seen the need for perfect rubber, the thought had come to him, with the force of a religious conviction, that “an object so desirable and so important, and so necessary to man’s comfort, as the making of gumelastic available to his use, was most certainly placed within his reach.” Thereafter he never doubted that God had called him to this task and that his efforts would be crowned with success. Concerning his prison experiences, of which the first was not to be the last, he says that “notwithstanding the mortification attending such a trial,” if the prisoner has a real aim “for which to live and hope over he may add firmness to hope, and derive lasting advantage by having proved to himself that, with a clear conscience and a high purpose, a man may be as happy within prison walls as in any other (even the most fortunate) circumstances in life.” With this spirit he met every reverse throughout the ten hard years that followed.

Luckily, as he says, his first experiments required no expensive equipment. Fingers were the best tools for working the gum. The prison officials allowed him a bench and a marble slab, a friend procured him a few dollars’ worth of gum, which sold then at five cents a pound, and his wife contributed her rolling pin. That was the beginning.

For a time he believed that, by mixing the raw gum with magnesia and boiling it in lime, he had overcome the stickiness which was the inherent difficulty. He made some sheets of white rubber which were exhibited, and also some articles for sale. His hopes were dashed when he found that weak acid, such as apple juice or vinegar, destroyed his new product. Then in 1836 he found that the application of aqua fortis, or nitric acid, produced a “curing” effect on the rubber and thought that he had discovered the secret. Finding a partner with capital, he leased an abandoned rubber factory on Staten Island. But his partner’s fortune was swept away in the panic of 1837, leaving Goodyear again an insolvent debtor. Later he found another partner and went to manufacturing in the deserted plant at Roxbury, with an order from the Government for a large number of mail bags. This order was given wide publicity and it aroused the interest of manufacturers throughout the country. But by the time the goods were ready for delivery the first bags made had rotted from their handles. Only the surface of the rubber had been “cured.”

This failure was the last straw, as far as Goodyear’s friends were concerned. Only his patient and devoted wife stood by him; she had labored, known want, seen her children go hungry to school, but she seems never to have reproached her husband nor to have doubted his ultimate success. The gentleness and tenderness of his deportment in the home made his family cling to him with deep affection and bear willingly any sacrifice for his sake; though his successive failures generally meant a return of the inventor to the debtor’s prison and the casting of his family upon charity.

The nitric acid process had not solved the problem but it had been a real step forward. It was in the year 1839, by an accident, that he discovered the true process of vulcanization which cured not the surface alone but the whole mass. He was trying to harden the gum by boiling it with sulphur on his wife’s cookstove when he let fall a lump of it on the red hot iron top.

It vulcanized instantly. This was an accident which only Goodyear could have interpreted. And it was the last. The strange substance from the jungles of the tropics had been mastered. It remained, however, to perfect the process, to ascertain the accurate formula and the exact degree of heat. The Goodyears were so poor during these years that they received at any time a barrel of flour from a neighbor thankfully. There is a tradition that on one occasion, when Goodyear desired to cross between Staten Island and New York, he had to give his umbrella to the ferry master as security for his fare, and that the name of the ferry master was Cornelius Vanderbilt, “a man who made much money because he took few chances.” The incident may easily have occurred, though the ferry master could hardly have been Vanderbilt himself, unless it had been at an earlier date.

Another tradition says that one of Goodyear’s neighbors described him to an inquisitive stranger thus: “You will know him when you see him; he has on an India rubber cap, stock, coat, vest, and shoes, and an India rubber purse WITHOUT A CENT IN IT!”

Goodyear’s trials were only beginning. He had the secret at last, but nobody would believe him. He had worn out even the most sanguine of his friends. “That such indifference to this discovery, and many incidents attending it, could have existed in an intelligent and benevolent community,” wrote Goodyear later, “can only be accounted for by existing circumstances in that community The great losses that had been sustained in the manufacture of gumelastic: the length of time the inventor had spent in what appeared to them to be entirely fruitless efforts to accomplish anything with it; added to his recent misfortunes and disappointments, all conspired, with his utter destitution, to produce a state of things as unfavorable to the promulgation of the discovery as can well be imagined. He, however, felt in duty bound to beg in earnest, if need be, sooner than that the discovery should be lost to the world and to himself… . How he subsisted at this period charity alone can tell, for it is as well to call things by their right names; and it is little else than charity when the lender looks upon what he parts with as a gift. The pawning or selling some relic of better days or some article of necessity was a frequent expedient. His library had long since disappeared, but shortly after the discovery of this process, he collected and sold at auction the schoolbooks of his children, which brought him the trifling sum of five dollars; small as the amount was, it enabled him to proceed. At this step he did not hesitate. The occasion, and the certainty of success, warranted the measure which, in other circumstances, would have been sacrilege.”

His itinerary during those years is eloquent. Wherever there
