Here's a biographical profile of Charles Goodyear, the man who gave the world one of its most useful products - vulcanized rubber. Natural rubber, the milky sap of rubber trees, is not a very practical commodity. It melts in hot weather or cracks and freezes in cold weather.

Here's a biographical profile of the Freelan and Francis Stanley, identical twins who developed the Stanley Steamers, cars powered by steam engines. In 1897 the brothers, dressed alike in overcoats, bowler hats and sporting thick black beards appeared on Maple Street in Watertown, Mass., driving a horseless carriage that was nearly soundless. Spectators were stunned by the quick pace and eerie silence. One observer later recalled: "It was like watching a pair of pants run down the street with nobody in them."

Here's a biographical profile of Charles and J. Frank Duryea, two visionaries who were among the first to recognize the potential of the automobile. In 1892 they built America's first gasoline-powered car and had it running successfully the following year.

Henry Ford, an American folk hero to many, was a man with several faces. He was a genius who revolutionized the automobile industry, irrevocably altered American culture and commerce, developed mass production, and helped the middle class emerge in America.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark.
