The Most Influential Women in Finance Throughout History
Women have long faced barriers in the world of finance, but throughout history, a select few have shattered expectations, built empires, and changed the financial landscape. Their strategies, resilience, and groundbreaking achievements continue to inspire investors and business leaders today. Here are some of the most influential women in finance and the key lessons they leave behind.
1. Hetty Green – The First Female Tycoon
Born in 1834, Hetty Green was a financial powerhouse long before women were widely accepted in business. Known as “The Witch of Wall Street,” she became the richest woman in America by using a contrarian investment approach. While industrial titans like Rockefeller and Carnegie built monopolies, Green amassed her fortune by buying undervalued assets during financial panics and keeping ample cash reserves to seize opportunities.
Her investment philosophy mirrored modern financial wisdom: “Buy when others are fearful, and sell when others are greedy.” She focused on railroads, real estate, and government bonds—safe but lucrative assets that allowed her wealth to grow steadily. Unlike many speculators of the Gilded Age, she avoided excessive debt and risky trends.
Beyond her financial acumen, Green was a sharp negotiator. Men often underestimated her, only to realize too late that she was an unrelenting dealmaker. She famously said, “It is the duty of every woman to learn to take care of her own business affairs.” In an era where women were largely excluded from banking and investing, she proved that financial intelligence and patience were more powerful than societal expectations.
Key Takeaways:
-
- Buy low, sell high—investing wisely requires patience and discipline.
- Financial independence is crucial, especially for women.
- Keeping cash reserves allows for opportunity in economic downturns.
2. Muriel Siebert – The First Woman on the New York Stock Exchange 
Muriel Siebert became the first woman to buy a seat on the New York Stock Exchange (NYSE) in 1967, earning her the title “First Woman of Finance.” At a time when Wall Street was an exclusive club for men, she applied to ten firms before one finally agreed to sponsor her membership. She also fought for equality, advocating for women’s restrooms on the NYSE trading floor—a change that took twenty years to be realized.
Beyond Wall Street, Siebert was a women’s rights advocate and philanthropist. She launched the Siebert Entrepreneurial Philanthropic Program, donating half of her firm’s profits to charities supporting women and underrepresented communities in finance and business. Later, as president of the New York Women’s Agenda, she introduced the Siebert Personal Finance Program, which became part of the New York City Schools curriculum, teaching essential financial skills to students and adults alike.
Her legacy goes beyond personal success—she actively paved the way for future generations of women in finance.
Key Takeaways:
- Persistence and resilience are essential when breaking barriers.
- Financial education empowers individuals and strengthens communities.
- Women’s leadership in finance contributes to a more inclusive economy.
3. Madam C.J. Walker – The First Female Self-Made Millionaire 
Born in 1867, Madam C.J. Walker built a haircare empire and became the first female self-made millionaire in the U.S. Her business acumen and marketing strategies not only revolutionized the beauty industry but also created economic opportunities for thousands of Black women.
She used her wealth to fund scholarships, donate to charities, and support civil rights organizations. Walker’s legacy is a testament to the power of entrepreneurship, resilience, and financial independence.
