Industrial mogul John D. Rockefeller had three daughters who lived into adulthood, but just one son, born last. His birth was remarked as fortunate, since it meant that JDR would have an heir.
Since the culture of the eighteenth, nineteenth, and early twentieth centuries was to endow the male heirs with the vast majority of business interests as inheritance, and not to give the daughters any business roles, I am curious about the following:
- Were there any other highly successful tycoon-types (think Carnegie, Nobel, Astor, Gould, etc.) who had only female offspring?
- If there were any such tycoons, how did they handle matters of inheritance? Did they train their daughters to business roles?
(There's also an unrelated question, slightly beyond the scope of this question: did any industrial tycoons -- regardless of the gender distribution of their offspring -- train their daughters for business roles?)
