John Boyd Dunlop (February 5, 1840 – October 23, 1921) was a Scottish inventor who founded the rubber company that bears his name, Dunlop Tyres.
He was born on a farm at Dreghorn, North Ayrshire, and studied to be a veterinary surgeon at the Dick Vet, University of Edinburgh, a profession he pursued for nearly ten years at home, moving to Belfast, Ireland, in 1867.
In 1887, he developed the first practical pneumatics tyre for his son's tricycle, tested it, and patented it on December 7, 1888. Dunlop's invention arrived at a crucial time in the development of road transport. Commercial production began in late 1890 in Belfast. Dunlop assigned his patent to William Harvey Du Cros, in return for 1500 shares in the resultant company, and in the end did not make any great fortune by his invention. Dunlop died in Dublin.
