Patrician Families and the Culture of Discretion — conclusion

Conclusion

The Daig, the old patrician families of Basel, formed a social elite of merchants, manufacturers, bankers, scholars and public servants, connected by marriage and kinship over centuries. They managed their wealth collectively, transmitted it through equal division among children and invested it in the family business, real estate, rents and foreign securities. Dominating public office, they introduced in 1718 the drawing of lots to combat corruption in appointments. Their members included Isaak Iselin, the leading figure of the Basel Enlightenment and founder of the GGG, Peter Ochs, the author of the constitution of the Helvetic Republic, Christoph Merian, who left his fortune to the city, and Jacob Burckhardt, the historian of the Renaissance.

Their culture of discretion, rooted in the Reformation, the experience of the refugees, the egalitarian civic tradition and the needs of business, became the social foundation of Swiss private banking. It survives in the modern law of privacy and banking confidentiality, redefined by the end of banking secrecy for foreign tax purposes. The next chapter follows the path by which the merchant houses of the Daig became banks.
