Intercontinental Exchange

Muriel “Mickie” Siebert was the first woman to own a seat on the New York Stock Exchange and the first to head one of its member firms, Muriel Siebert & Co., Inc. Siebert was also a pioneer in the discount brokerage field, transforming her firm into a discount brokerage in 1975. In 1977, she put her firm in a blind trust to serve as New York State’s first woman Superintendent of Banking and under her watch, not a single banking institution failed.

Muriel Siebert became involved in countless organizations that focused on developing, supporting and connecting female leaders. She was one of the first members of the Women’s Forum of New York when she was asked to join by Elly Guggenheimer in 1974.

In 2016 the NYSE dedicated a newly renovated meeting space, Siebert Hall, in her honor. At the dedication, NYSE President Tom Farley stated: “When Mickie became the first female member of the NYSE in 1967, she shattered a glass ceiling on Wall Street. So, when it came time to dedicate our newly-renovated meeting hall - a contemporary counterpart to our more traditional Boardroom - the progressive and ground-breaking Mickie was the obvious choice.”

In late 2017, we marked the 50th anniversary of Siebert’s NYSE membership.
