One day, in 1834, a Philadelphia hardware merchant, named Charles Goodyear, was led by curiosity to buy a rubber life-preserver. And thus began for this unfortunate genius nearly twenty-five years of struggle, misery, and disappointment. Charles Goodyear was born in New Haven, Conn., December 29, 1800. When a boy his father moved to Philadelphia, where he engaged in the hardware business, and upon becoming of age, Charles Goodyear joined him as a partner. In the panic of 1836-1837 the house went down. Goodyear's attention had been attracted for several years by the wonderful success of the india-rubber companies. Upon examining his life-preserver he discovered a defect in the inflating valve and made an improved one. Going to New York with this device, he called on the agent of the Roxbury Company and, explaining it to him, offered to sell it to the company. The agent was impressed with the improvement, but instead of buying it, told the inventor the real state of the india-rubber business of the country, then on the verge of a collapse. He urged Goodyear to exert his inventive skill in discovering some means of imparting durability to india-rubber goods, and assured him that if he could find a process to effect that end, he could sell it at his own price. He explained the processes then in use and their imperfections. Goodyear forgot all about his disappointment in failing to sell his valve, and went home intent upon experiments to make gum-elastic durable. From that time until the close of his life he devoted himself solely to this work. He was thirty-five years old, feeble in health, a bankrupt in business, and had a young family depending upon him. The industry in which he now engaged was one in which thousands of persons had found ruin. The firm of which he had been a member owed $30,000, and upon his return to Philadelphia he was arrested for debt and compelled to live within prison limits. He began his experiments at once. The price of the gum had fallen to five cents per pound, so that he had no difficulty in getting sufficient of it to begin work. By melting and working it thoroughly and rolling it out upon a stone table, he succeeded in producing sheets of india-rubber that seemed to him to possess new properties. A friend loaned him enough money to manufacture a number of shoes which at first seemed to be all that could be desired. Fearful, however, of coming trouble, Goodyear put his shoes away until the following summer, when the warm weather reduced them to a mass of so offensive an odor that he was glad to throw them away. His friend was so thoroughly disheartened by this failure as to refuse to have anything more to do with Goodyear's scheme. The inventor, nevertheless, kept on.
