From Dyes to Chemistry: Geigy, Ciba, Sandoz and Roche — conclusion

Conclusion

The chemical industry of Basel grew out of the silk dyeing tradition of the city. Its founders, many of them from Lyon and Alsace, began producing synthetic dyes in 1859, attracted by the absence of patent protection in Switzerland and by the capital, water and markets that Basel offered. Alexander Clavel's business became Ciba. The Geigy family turned from the dye trade to dye production. Its early fuchsine production caused the arsenic contamination of the 1860s, one of the first environmental scandals of the industry. Kern and Sandoz founded Sandoz in 1886. The absence of patent protection allowed the industry to grow by imitation until the revision of 1907 introduced protection for chemical processes.

The First World War gave the Basel companies a windfall when German competition disappeared. In 1918 Ciba, Geigy and Sandoz formed the Basel IG, a cartel that lasted until 1951. The companies moved into pharmaceuticals. Sandoz developed ergotamine and, through Albert Hofmann, discovered LSD. Roche, founded in 1896 by Fritz Hoffmann-La Roche as a pharmaceutical company with branded, standardised medicines and international ambitions, survived a near-collapse after the First World War and became the world's leading vitamin producer. Geigy's discovery of DDT saved countless lives before its environmental damage led to its prohibition. By 1945, the chemical industry dominated the Basel economy and shaped its financial centre. The next chapter turns to the banks.
