Title: Charles Goodyear
Content:  Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844. Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock. His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire and Rubber Company is named after him.

Content:  From 1834 through 1839, Goodyear worked anywhere he could find investors, and often moved locations, mostly within New York, Massachusetts, Philadelphia, and Connecticut. In 1839, Goodyear was at the Eagle India Rubber Company in Woburn, Massachusetts, where he accidentally discovered that combining rubber and sulfur over a hot stove caused the rubber to vulcanize. For this Goodyear and Nathaniel Hayward received US patent number 1,090 on February 24 of the same year. Several years earlier, Goodyear had started a small factory at Springfield, Massachusetts, to which he moved his primary operations in 1842. The factory was run largely by Nelson and his brothers. Charles Goodyear's brother-in-law, Mr. De Forest, a wealthy woolen manufacturer became involved as well. The work of making the invention practical was continued. In 1844, the process was sufficiently perfected and Goodyear received US patent number 3633, which mentions New York but not Springfield. Also in 1844, Goodyear's brother Henry introduced mechanical mixing of the mixture in place of the use of solvents. Goodyear sold some of these patents to Hiram Hutchinson who founded Hutchinson SA in France in 1853.

But in the heat of summer, rubber goods turned into a gooey, foul-smelling mess; in the winter, they froze stiff. In 1839, Charles Goodyear had a breakthrough when he mixed liquid latex with sulfur and heating it in the sun or over a stove top. The leather-like form of the stretchable substance resulted in the first vulcanized rubber. Goodyear received a patent on June 15, 1844.

Content:  Goodyear died on July 1, 1860, while traveling to see his dying daughter. After arriving in New York, he was informed that she had already died. He collapsed and was taken to the Fifth Avenue Hotel in New York City, where he died at the age of 59. He is buried in New Haven at Grove Street Cemetery. In 1898, almost four decades after his death, The Goodyear Tire & Rubber Company was founded and named after Goodyear by Frank Seiberling. On February 8, 1976, he was among six individuals selected for induction into the National Inventors Hall of Fame. In Woburn, Massachusetts, there is an elementary school named after him. The Government of France made him a Chevalier de la Légion d'honneur in 1855. The ACS Rubber Division awards a medal named in Goodyear's honor, the Charles Goodyear Medal. The medal honors principal inventors, innovators, and developers whose contributions resulted in a significant change to the nature of the rubber industry. The Goodyear welt, a technique in shoemaking, was named after and in honor of its inventor, Charles' son; Charles Goodyear Jr.
Title: Charles Goodyear Medal
Content:  The Charles Goodyear Medal is the highest honor conferred by the American Chemical Society, Rubber Division. Established in 1941, the award is named after Charles Goodyear, the discoverer of vulcanization, and consists of a gold medal, a framed certificate and prize money. The medal honors individuals for "outstanding invention, innovation, or development which has resulted in a significant change or contribution to the nature of the rubber industry". Awardees give a lecture at an ACS Rubber Division meeting, and publish a review of their work in the society's scientific journal Rubber Chemistry and Technology.

The goods that were made in this way were beautiful to look at, and it appeared, as it had before, that all difficulties were overcome. Goodyear discovered a new method for making rubber shoes and received a patent which he sold to the Providence Company in Rhode Island. However, a method had not yet been found to process rubber so that it would withstand hot and cold temperatures and acids, and so the rubber goods were constantly growing sticky, decomposing and being returned to the manufacturers.
Title: Rubber Company v. Goodyear
Content:   Charles Goodyear invented a process for "vulcanizing" rubber by heating it to a high temperature in the presence of sulfur and lead carbonate or another chemical, so that it was converted from a soft, sticky, gummy product (so-called India rubber) to a hard, resilient, elastic, flexible product (so-called vulcanized rubber). Goodyear was issued a patent on the process by which vulcanized India-rubber is manufactured and another patent for the product that the process produced. In 1846, Goodyear granted what amounted to a royalty-free exclusive license to E.M. Chaffee, the assignor to the Providence Rubber Company (Providence), to "use" the patented "metallic gum-elastic composition for coating of cloths for the purpose of japanning, marbling, and variegate japanning,

Between the years 1831 and 1832, Goodyear heard about gum elastic (natural rubber) and examined every article that appeared in the newspapers relative to this new material. The Roxbury Rubber Company, of Boston, had been for some time experimenting with the gum, and believed it had found means for manufacturing goods from it. It had a large plant and was sending its goods all over the country. It was some of Roxbury's goods that first attracted Goodyear's attention. Soon after this, Goodyear 
Title: Condom
Content:  In 1839, Charles Goodyear discovered a way of processing natural rubber, which is too stiff when cold and too soft when warm, in such a way as to make it elastic. This proved to have advantages for the manufacture of condoms; unlike the sheep's gut condoms, they could stretch and did not tear quickly when used. The rubber vulcanization process was patented by Goodyear in 1844. The first rubber condom was produced in 1855. The earliest rubber condoms had a seam and were as thick as a bicycle inner tube. Besides this type, small rubber condoms covering only the glans were often used in England and the United States. There was more risk of losing them and if the rubber ring was too tight, it would 

Question: when did charles goodyear invented rubber?
Answer: During the early 1830's he began inventing, filing six patents between 1830 and 1834, and during this period became interested in rubber, which he tried - unsuccessfully - to use in some of his mechanical inventions.
