Charles Goodyear invented latex condoms.

In 1839, by dropping on a hot stove some india-rubber mixed with sulfur, he discovered accidentally the process for the vulcanization of rubber. Two years more passed before he could find any one who had faith enough in his discovery to invest money in it. At last, in 1844, by which time he had perfected his process, his first patent was granted, and in the subsequent years more than sixty patents were granted to him for the application of his original process to various uses, including rubber condoms, intrauterine devices, douching syringes, and "womb veils" (diaphragms).
