Siebert wasn't the first woman to rise above gender discrimination in the world of finance. One of the earliest documented female investors in the U.S. was Abigail Adams, who ignored her husband John's instructions to invest in land while he was stationed overseas, and instead made a much larger return investing in U.S. government bonds. Contemporary accounts describe Abigail's foray into the investing world as the one source of contention in the couple's otherwise happy marriage, despite her success.
There are also abundant examples of women who went out of their way to de-emphasize or even hide their gender to foster their careers in finance. Among them were the first women to own a Wall Street brokerage, sisters Victoria Woodhull and Tennessee Claflin, who had custom-made business dresses designed to hide their femininity and blend in with their male colleagues. Even so, the New York Times headline that announced the firm's opening in 1870 read "Wall Street Aroused," and the story's reporter concluded that "A short, speedy winding up of the firm of Woodhull, Claflin & Co. is predicted."
