Leadership

Five Lessons from a Wall Street Trailblazer

As the first woman to buy a seat at the New York Stock Exchange, Muriel Siebert spent a lifetime breaking barriers. Her legacy, explored through an exhibit at Harvard Business School's Baker Library, offers lessons for all executives.

Muriel Siebert lacked the usual contacts or credentials valued on Wall Street. She liked to say that she arrived in New York City in 1954 with a used Studebaker and $500. Siebert, originally from Cleveland, Ohio, did have strong math skills, courage, and a sister who let her sleep on her sofa while she looked for work.

A year before moving to the city, while visiting her sister, Siebert had toured the New York Stock Exchange (NYSE): "What I saw as I looked down from the visitors’ gallery was a sea of men in dark suits [...] But after absorbing all that fierce energy, I turned to my friends and said, 'Now, this is exciting,'" she recalled in her autobiography.

About a decade later, in 1967, Siebert became the first woman to hold a seat at the NYSE and the first to own and operate a brokerage firm there. She was also the first woman appointed to the powerful position of superintendent of banks for the State of New York.

In 2019, the Muriel Siebert Foundation donated her archive to Baker Library, including calendars, business reports, photos, and articles. An exhibit at Harvard Business School’s library, “Muriel Siebert: Redefining Power and Possibility on Wall Street,” features key items from the collection. These are five lessons we took from her extraordinary journey as a business leader who carved her own path to success.

1. Persistence pays off

When you hit a closed door and it doesn’t budge, just rear back and kick it in—but hold it open so others can follow you.

After being rejected by the United Nations and Merrill Lynch, Muriel Siebert found a job at Bache & Co., a smaller brokerage firm. She was hired as a trainee researcher and later promoted to analyst —one of only three women in that role. Her salary doubled in a couple of years, but it was still lower than that of her male colleagues. She moved to Shields & Co. and became a senior securities analyst and went on to Stearns & Co. and other top firms, where she was became a partner.

Still, she hadn’t achieved equal pay. When she asked a client for advice on which firm she could join to earn the same as her male colleagues, he replied: “Don’t be ridiculous, you won’t. Buy a seat. Work for yourself.”

Siebert asked nine members to sponsor her, but all refused. Eventually, two former colleagues agreed to support her. The seat cost $445,000. On December 29, 1967, Siebert became the “First Lady Member of the New York Stock Exchange,” according to an ad announcing her membership.

2. Challenges fueled her determination

On top of being paid less, Siebert faced many daily challenges: when she attended a board meeting at the men’s Union League Club, she was not allowed to use the elevator. There was also no women’s restroom at the NYSE Luncheon Club. After her experiences, Siebert founded and participated in organizations that supported women in business, like the Women’s Forum and the Committee of 200. She also testified in support of a bill that banned business activities in clubs that excluded women.

“Mentors for women didn’t exist when I started on Wall Street,” Siebert wrote. “It makes you a feminist when you’re making $150 a week and the man sitting next to you is making $300,” she later said in a 1982 interview with Albany Times Union.

3. Develop a personal brand

Before selfies and social media, Siebert knew the power of public relations. She commissioned multiple ads marking major milestones, often contributed to the press, and became a respected speaker at conferences.

4. Create your own game

In June 1969, Siebert was the first woman to own and operate a firm—Muriel Siebert & Co.—on the NYSE. When the Securities and Exchange Commission introduced rules allowing members to negotiate fees, Siebert was among the first to convert her company into a discount brokerage.

Years before that, she had started building a name for herself by diligently learning everything she could about industries that were “dumped” on her as a trainee, such as airlines and movies. That extensive knowledge helped her build future clients.

If you can’t play with the big boys’ ball, start your own game.

5. Use your voice and influence, keep your sense of humor

As superintendent of banks, Siebert oversaw 500 banking institutions, including $400 billion in assets and $100 billion in trust accounts. After a tumultuous few years, she realized that financial laws needed to change. She ran for Senate in 1982.

After losing the Democratic primary, when only one woman held a Senate seat, she returned to her firm and worked to rebuild it.

My motives have always been pride, principle and profit. I don’t know how you stay afloat and sleep at night without all three,” she wrote in her book “Changing the Rules: Adventures of a Wall Street Maverick.”

Siebert was also involved in numerous charities and became a champion of early financial literacy, promoting financial education in colleges and high schools. In 1990, she launched the Siebert Entrepreneurial Philanthropic Plan, which gave 50% of its profits to local charities.

In 1972, Siebert was invited to speak to MBA students at HBS. Her speech began with humor: “When I received the invitation to speak here, I thought of the Virginia Slim cigarette ad: You’ve come a long way baby. As a woman who has succeeded in a man’s world, I’d like to say 'Baby—you’ve got a long way to go.'”

Siebert kept working until her final days. She died at 84. In 2016, three years after her death, the NYSE opened the first hall dedicated to an individual, Muriel F. “Mickie” Siebert.
