Early Life and Education

Muriel Siebert was born on Sept. 12, 1928, in Cleveland, Ohio. She briefly attended Western Reserve University without completing a degree. Determined to begin her career on Wall Street, Siebert attained her first position with Bache & Company in 1954 by claiming she had successfully graduated from college. She held positions with three brokerage firms in New York City.

Seat on the NYSE

Frustrated by the pay inequity that she experienced working on Wall Street, Muriel Siebert pursued a seat on the New York Stock Exchange (NYSE). This would allow her to buy and sell shares directly on the trading floor. Although women were not prohibited from owning a seat, Siebert spent two years locating a sponsor for her application and a bank that would allow her to borrow the required $300,000. On Dec. 28, 1967, Siebert became the first woman to buy a seat and become a member of the NYSE.

Muriel Siebert & Company

In 1969, Muriel Siebert founded Muriel Siebert & Company. She was the first woman to own and run a brokerage firm that was a member of the NYSE. However, Siebert’s career was marked by the changing status of women in the workplace during the 1960s. Outright or subtle discrimination was evident and women faced limited access to important deal-making at New York City's all-male lunch clubs. Siebert's Jewish heritage also highlighted her exclusion, during years in which anti-Semitism was commonplace in the corporate world.

Muriel Siebert & Company continues to operate in New York City and has 15 branch offices nationwide. It is a subsidiary of Siebert Financial Corp, a holding company that also owns and operates an investment advisory and insurance arm.
