The pneumatic tyre was a discovery stolen by a patent battle
In short: John Boyd Dunlop didn't just invent the pneumatic tyre; he lost the rights to it almost immediately. While his child's tricycle revolutionized travel, a 1845 patent by a different inventor forced the Dunlop family into a decades-long struggle to protect their brand and industrial legacy.
In 1888, Scottish veterinary surgeon John Boyd Dunlop discovered the principle of the pneumatic tyre while designing a tricycle for his child. His invention was quickly popularized by Willie Hume, who won seven out of eight cycle races using the technology. However, the legal foundation of the business was precarious. In 1890, Dunlop's patent was withdrawn after it was discovered that Robert William Thomson had actually patented the pneumatic tyre in 1845. This forced Harvey du Cros and Dunlop to navigate significant legal difficulties, eventually acquiring various other rights and patents to shield their commercial position.
The company, originally founded as Pneumatic Tyre in 1889, became a pioneer of the multinational model. To maintain foreign patent rights, the company established factories in Europe and North America, often partnering with local firms like Clement Cycles in France and Adler in Germany to limit capital expenditure. By 1901, the entity was renamed Dunlop Rubber, and it began a period of intense diversification. While it dominated the cycle market, it also moved into motor car tyres in 1900, aeroplane tyres in 1910, and even produced golf balls and tennis balls.
Despite its massive scale—reaching 70,000 employees by 1946 and holding nearly half of the UK tyre market by the early 1950s—the company faced structural hurdles. It struggled with market shifts, such as the rise of radial tyres in the 1960s, and suffered from a disastrous 1971 merger with Italy's Pirelli. The merger, intended to create the world's third-largest tyre company, was dissolved by 1981 after failing to turn a profit. By 1985, the company was acquired by BTR, marking the end of its era as a primary British industrial titan.
