I never heard of her but she amassed by the early 20th Century a fortune equivalent to over a billion dollars all on investments. This video shows how she did it an her life in which she was called The Witch of Wall Street and how there was a lot of myths about her. More then likely folks who were jealous and misogynistic.
Really interesting video that came out about an hour ago about 10 minutes long. Her heirs and grandchildren ended up giving all the money to charity.
They need to make a movie about her.
