A brief article in the October 24 1925 edition of the Toronto Daily Star mentioned that a teenage girl was about to become very wealthy.
James Buchanan Duke (1856-1925) and his father gave enough money to a small college in North Carolina that it was renamed after them. It is now Duke University.
Doris Duke (1912-1993) became known as “the richest girl in the world” after receiving her father’s bequest. Looking at her biography, it looks like she did the sort of things that people with a lot of money do: philanthropy, buying real estate, various hobbies and interests.
