1 A Physical Paradox Asbestos...the world’s most wonderful mineral. A. L. Summers, Asbestos and the Asbestos Industry (1919). ASBESTOS WORKER’S DEATH: MINERAL PARTICLES IN LUNGS THE FIRST CAUSE Headline in the Rochdale Times, 2 Apr. 1924. the asbestos giant On a blustery and showery morning in August 1924, a funeral procession gathered in Rochdale, a town some 8 miles north of Manchester. After a service at a house in one of the better-class districts in the town, the mourners began the slow journey towards the town cemetery. It was a funeral cortège in the grand Victorian manner. Several hundred people had gathered in the town centre to pay their respects, and as the hearse headed past the Town Hall and out towards the cemetery it was followed by nearly sixty carriages and motor cars. At the graveside, fulsome tribute was paid to one of Rochdale’s most famous sons. The dead man was Sir Samuel Turner, an 84-year-old industrialist, who had died from a stroke the previous week at a hotel in Harrogate. The Turners were one of the town’s leading families: worthy Victorian ‘men of mark’, who could be said to have risen from humble origins by dint of their own ‘enterprise’ and practical skill. An honorary freeman and former mayor of Rochdale, Samuel Turner had been knighted in 1914, when he already had the wealth and trappings of a latter-day multi- millionaire. As a Methodist and Liberal, Turner had naturally balanced his wealth with paternalism and a commitment to the local community. His residence, Chaseley, from where his funeral cortège set out, was opposite the park he had donated to the town. To one obituarist, Turner’s career was an uplifting tale of ‘commercial romance’.1 Its origins lay, appropriately, in that seedbed of the Industrial Revolution—the Lancashire textile industry—in a town famous for its production of flannel. Among Rochdale’s fertile textile and engineering 1 Rochdale Observer, 13, 23 Aug. 1924. 2 Physical Paradox base was the calico-weaving business of Samuel Turner & Company. It had been founded by Sir Samuel Turner’s father—confusingly also named Samuel Turner (1807–80)—who in 1856 had occupied the Clod Mill in Spotland, a district only a mile or so west of the town centre. Samuel Turner I had three sons—John, Robert, and Samuel—who in 1871 launched Turner Brothers, a separate operation within Clod Mill. The new venture was established to manufacture cotton seals (packings) for keeping the pistons of engines steam-tight. The inspiration for this busi- ness was the second Samuel Turner (1840–1924), the owner’s son and the man later buried with such ceremony in Rochdale Cemetery. In 1879, hindered by the deficiencies of cotton as a packing material, Turner had seized on the availability of what was then a relatively little-known indus- trial raw material—asbestos. A naturally occurring mineral, asbestos had been known since ancient times, though originally more as an object of wonder and curiosity than as a useful item of commerce. A folklore had grown up around the ma- terial. The Greeks were believed to have used asbestos wicks in lamps for their temples; while another story has Charlemagne astonishing guests by cleaning an asbestos tablecloth by fire. Royal bodies were said to have been wrapped in asbestos cloth to prevent their ashes mingling with those from the funeral pyre: hence, asbestos became known as the funeral dress of kings. Certainly the indestructible and fireproof qualities of asbestos were well appreciated before the modern commercial era began in the late nineteenth century.2 A key event occurred in the 1870s in Canada, where a forest fire in the Thetford area near Quebec revealed large deposits of the material. By the time Samuel Turner II saw his first asbestos, geologists had already described its main characteristics and had divided the fibrous mineral into two geological classifications—serpentine and amphibole (Table 1.1 and Figure 1.1). Chrysotile (or white asbestos) was the material that Turner would have seen first. This type of asbestos, which was to be mined in substantial quantities in Canada, was to dominate the industry and eventually accounted for some 95 per cent of asbestos mined world- wide. Crocidolite (blue asbestos) was also known in the nineteenth century, but it never became as significant commercially: it did, however, have exceptional acid resistance. The other important form, known as amosite (brown asbestos)—a name derived from the Asbestos Mines of South Africa—was to become available after 1917 and was prized for its fire-resistance. Like the ancients, nineteenth-century industrialists were fascinated by a mineral that, when crushed, released a multitude of soft filaments. 2 The ancient history is documented in I. J. Selikoff and D. H. K. Lee, Asbestos and Disease (1978), 3–8. Physical Paradox 3 Table 1.1.

Asbestos groups Asbestos was described as one of the most ‘marvellous productions’ of inorganic nature—‘a physical paradox’—that combined the properties of rock and silk and could be spun into strands that weighed less than an ounce to a hundred yards.3 It now had more than curiosity value. As Europe and America industrialized, asbestos became inextricably linked 3 R. H. Jones, Asbestos and Asbestic (1897), 1–2. 4 Physical Paradox with the new steam age. Steam was synonymous with heat; and where there was heat, fireproofing and insulation materials were essential. Asbestos was the logical choice, because it resisted decay and destruction by superheated steam or grease. Contemporaries noted admiringly that it was impervious to the pounding meted out by marine, hydraulic, or other engines: ‘So little influence of a chemical nature does [asbestos] exert over any metal, with which it is brought into contact, that, if a joint be broken, the surfaces will be found entirely free from corrosion. Moreover, its incombustible nature and slow conduction of heat render it a complete protection from flames.’4 Turner had realized that asbestos would be ideal in the packings for steam engines and also for insulation. He saw at once ‘the commercial value of the article, providing it could be spun and manufactured’.5 Turner’s breakthrough was to spin and weave asbestos by power-driven machinery. The tough and slippery asbestos fibres made this difficult, but the problem was solved by adding a small amount of cotton or other organic fibre to the mineral.6 Turner recalled: ‘No sooner was it discov- ered that I could produce packing indestructible by heat than the demand became out of all proportions to supply.’ Later he would utilize other innovations from America and Austria. These included adding asbestos fibre to magnesia for use in pre-formed insulation products; and mixing asbestos with cement to produce sheets for roofing and walls.7 All these products made use of asbestos’s indestructibility, high tensile strength, and fireproofing and insulating properties. Turner Brothers (which in 1880 employed only about five hands) was not the first British company to market asbestos, but it led the way in its large-scale production.8 Alongside the original and successful cotton busi- ness, Turner Brothers began growing steadily. By 1900, about fifty were employed in the asbestos side of the business, which occupied the south- ern end of the Spotland site. A decade later, employment was over 300. By 1914, asbestos production at the factory embraced a wide variety of asbestos cloths, including rubber-proofed varieties, besides compressed asbestos fibre (CAF) jointing, and brake linings. In 1913, the company had also opened an asbestos cement plant on the fast-growing industrial estate in Trafford Park, Manchester, which would later tap the huge twentieth- century market for asbestos-cement building materials. 4 Jones, Asbestos, 2–3. 5 Rochdale Observer, 13 Aug. 1924, quoting Family Circle, 27 Aug. 1895. 6 On the technical problems, see W. J. Ellison, ‘Early Years in the Life of Turner Brothers Asbestos Company Ltd’, Firefly (Winter Supp., 1966), 13–20. 7 Magnesia insulation contained up to 15 per cent asbestos; for asbestos cement, the figure was between 15 and 30 per cent asbestos (usually chrysotile). 8 W.

Physical Paradox 5 During the First World War, the firm—renamed Turner Brothers Asbestos (TBA)—continued to expand and not only in Rochdale. The company took its first steps towards multinational status, with the regis- tration in 1907 of a Canadian selling agency (later known as Atlas Asbestos). All the fibre used in Britain had to be imported: that, and the fact that the quality from different suppliers was often variable, led Turner to integrate backwards into asbestos mining.9 In 1917, TBA directors were appointed to the board of the Rhodesia & General Asbestos Corporation, as the company began buying up mines in the Mashaba district in southern Rhodesia. By the early twentieth century, sales of asbestos were booming. TBA had single-handedly repeated the trick of the Lancashire textile industry by taking a common, relatively cheap imported raw material, and then transforming it with local expertise into a profitable product.
