John Boyd Dunlop, Scottish businessman, founded Dunlop Rubber (born 1840)

John Boyd Dunlop was a Scottish inventor and veterinary surgeon who spent most of his career in Ireland. Familiar with making rubber devices, he invented the practical pneumatic tyres for his child's tricycle and developed them for use in cycle racing. He sold his rights to the pneumatic tyres to a company he formed with the president of the Irish Cyclists' Association, Harvey du Cros, for a small cash sum and a small shareholding in their pneumatic tyre business. Dunlop withdrew in 1896. The company that bore his name, Dunlop Pneumatic Tyre Company, was not incorporated until later and, despite its name, was Du Cros's creation.

Dunlop Ltd. was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre: he invented the first practical pneumatic tyres for his child's tricycle. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J. B. Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephen Street, Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores.
