Laqueur and Organon. The university laboratory and the pharmaceutical industry in the Netherlands Since the 1970s cooperation between universities and pharmaceutical firms is business as usual. This has not always been the case. The first alliances between academic scientists and the pharmaceutical industry can be traced back to the 1920s. Compared to the U.S. and most other European countries, the creation of networks between the Dutch academe and industry shows a rather peculiar pattern that is illustrative in clarifying how the relationships between scientists and the pharmaceutical companies were built. Dutch scientists could not ally themselves with the pharmaceutical industry, simply because no Dutch pharmaceutical company specialized in organpreparations existed prior to the 1920s. This situation forced scientists to opt for the strongest form of alliance they could create, namely to take part in the founding of a pharmaceutical company. Ernst Laqueur, a professor in pharmacology at the University of Amsterdam, was one of the three founders of Organon, the Dutch pharmaceutical firm that was founded in 1923. Based on an analysis of the early history of sex endocrinology, this paper examines the creation of networks between Laqueur and Organon. The paper concludes that the university laboratory played a crucial role in the development of Organon. Organon was dependent on Laqueurs laboratory for the provision of the required biological essay techniques in order to manufacture standardized hormone products. Moreover, Laqueur mediated all the contacts between Organon and the clinic, required for the clinical testing of hormones and the provision of raw materials for the making of hormones into chemicals and drugs.
