Many of the Germans who came to the United States in the nineteenth century were entrepreneurs, some in the more mundane sense of owning their own businesses, others in the more exciting sense of being innovators within various business sectors. Germans also appear to have been more likely to engage in entrepreneurial activities on a scale large enough to require the formation of corporations. That hypothesis stems from the analysis of a database of the names of several hundred thousand incorporators, people (mostly men) who helped for-profit businesses to receive special charters granted by state legislatures across the United States between 1790 and 1861.
