Tires
John B. Dunlop was born in Aryshire, Scotland. After completing his schooling, Dunlop practiced as a veterinary surgeon first in Edinburgh, Scotland, andthen in Belfast, Ireland. In 1887 Dunlop was asked by his young son to thinkof some way to make the boy's tricycle ride more comfortably on Belfast's cobblestone streets. Dunlop began experimenting with improvements to the tricycle's solid rubber tires. He cut up an old garden hose, made it into a tube, pumped it up with air, and fitted it to the rear wheels of his son's tricycle.Dunlop had reinvented the pneumatic tire, which, unknown to Dunlop, had firstbeen invented by Robert Thomson in 1845.Dunlop tested and patented his pneumatic tire in Great Britain in 1888, and secured a U.S. patent in 1890. An Irish industrialist named W. H. Du Cros became interested in Dunlop's invention after a cyclist won a Belfast race with his pneumatic-tired bicycle. Du Cros organized a company with Dunlop, which became the Dunlop Rubber Company, eventually a worldwide concern.Dunlop did not profit greatly from his invention. He sold his patent and interest in the company to Du Cros in 1896 and retired to Dublin, where his onlybusiness activity until his death there in 1921 was an interest in a draperyfirm.
