Dunlop Rubber was a British multinational involved in the manufacture of various rubber goods. Its business was founded in 1889 in conjunction with Harvey du Cros by John Boyd Dunlop who had discovered the pneumatic tyre. 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. The Dunlop name was not used for any part of the business until after J B Dunlop's retirement in 1895.
