  • Pirelli Dunlop Union (1970-1981)
    A T ROUBLED INTERNATIONAL MERGER PIRELLI DUNLOP UNION (1970-1981) Franco Amatori - Università Bocconi, Milan, Italy [email protected] Fabio Lavista - Università Bocconi, Milan, Italy [email protected] WORK IN PROGRESS Prepared exclusively for discussion in occasion of the EBHA Conference, Geneva, September 2007. Please do not cite. The Announcement On March 2, 1970 Sir Reay Geddes and Mr. Leopoldo Pirelli, the respective leaders of tire manufacturers Dunlop and Pirelli, each sent shareholders a letter with a very similar content, informing recipients that negotiations for a merger between the two corporations were at an advanced stage. In fact, by December extraordinary assemblies at each of the companies had officially decided to approve the merger between the two groups. The Pirelli Dunlop Union from this legal act was born a multinational enterprise that ranked number 3 in the rubber industry (behind American giants, Goodyear and Firestone). If in the early 70s Goodyear had a turnover of almost 3 billion dollars and Firestone could vaunt one of 2.1 billion, Dunlop-Pirelli’s combined turnover of slightly more than 2 billion preceded those of General Tyre (1 billion) and Michelin (900 million). The Anglo-Italian group employed 178,000 persons (76,000 were within Pirelli and the remaining 102,000 were with Dunlop). Dunlop-Pirelli was a global company present in all five continents. In the letters sent to shareholders in March 1970, Pirelli and Geddes had written that in the late 60s their companies results were to be considered satisfactory but in a climate of harsh international competition they had to do much more in terms of rate of growth and geographical and product diversification.

John Boyd Dunlop’s son complained that his solid tyre tricycle was uncomfortable and jarred as he rode along the stony streets on his way to school. John Boyd came up with the idea to wrap a rubber tyre inflated with air round the rims of his son’s tricycle and tested it by rolling it along the floor. The pneumatic tyre went much further compared Corporate Overview 4 to the solid tyre. John Boyd Dunlop had made history! 1888 Dunlop knew that his invention had endless potential and commercial possibilities. He patented his ‘chamber of rubber or other suitable material to contain air under pressure or otherwise, fastened to the rim by the most convenient method’ or, as General Information 6 we’ve come to know it, the tyre.

  • From the Archives History of Dunlop Sports the Previous Article in The
    From the Archives History of Dunlop Sports The previous article in the Roehampton Club Recorder referred to two members of the Du Cros family who had joined the Club and were involved in the early beginnings of the Dunlop Company. From subsequent research into the history of the Company and the use of the Census records in 1911, it is now apparent that Harvey du Cros who had joined Roehampton Club in 1913 was in fact the founder of the Dunlop Company and not the fourth son with the same name as mentioned in the previous article. The census records in 1911 confirm a local address for the 64-year-old Harvey du Cros with his 31-year-old wife Florence, his 7-year-old daughter Patricia and eight members of staff ranging from a Hospital Nurse, Lady’s Maid, Domestic Cook, two Housemaids, Scullery Maid, Harvey du Cros Butler and Footman. The records also confirm the Middlesex address for Arthur Philip du Cros – third son to the founder of the Dunlop Company. Philip also held a senior role in the business as Managing Director. His successful career was also evident from the 1911 census which included references to no less than five servants in his employ. By the time Philip joined Roehampton Club in 1919, the Dunlop business had expanded from the manufacture of pneumatic tyres to extend its influence in the sporting world. The origins of the company were borne from the world of cycle racing when Harvey du Cros was President of the Irish Cyclists Association and his sons were competing regularly in competitive cycle events where he met John Boyd Dunlop.

  • The Technological and Commercial Battles (1910-1915)
    CHAPTER 11 suggested citation: Medrano-Bigas, Pau. The Forgotten Years of Bibendum. Michelin’s American Period in Milltown: Design, Illustration and Advertising by Pioneer Tire Companies (1900-1930). Doctoral dissertation. University of Barcelona, 2015 [English translation, 2018]. THE TECHNOLOGICAL AND COMMERCIAL BATTLES (1910-1915) Since its inception in the tire business in 1896 to the first decade of the 1900s, Michelin’s ambitions and market context changed substantially. The company competed for continental business from their French bulwark and their strategic centers in Italy—the factory of Turin was operative since 1907—and the United Kingdom—with agency in London since 1905—as well as their delegations in other Euro- pean countries. However, also had to coordinate their strategies in a global market that also included territories such as the American continent or Australia and New Zealand. The Michelin Tire Company of Milltown, in particular, focused their efforts between 1910 and 1915 on adequately positioning themselves, as expressed by Vice President Jules Hauvette Michelin in a 1915 November news item: “(…) the last three or four years had been spent in getting together a first class organization, in feeling out the trade and in closing selling arrangements on a large scale with represen- tative tire dealers throughout the country.”1 During this period, the strengthening of traditional com- petition and the appearance of new emerging firms was accompanied by constant evolution and tech- nological improvement. The French multinational company, within the context of their historical and solid positioning in different markets, was slow in reacting.2 1. From the smooth and rough As in many other fields of industry subject to fierce competition, the technological achievements of proven solvency obtained by one tire company were quickly absorbed or imitated by the rest.
