Siebert Financial Corp. (Nasdaq:SIEB) and Kennedy Cabot Acquisition, LLC today announced the dedication of Siebert Hall at the New York Stock Exchange (NYSE) in honor of the late Muriel F. "Mickie" Siebert, who became the first woman to both own a seat on the NYSE and head one of its member firms, Muriel Siebert & Co., Inc., on December 28, 1967. Jane Macon, Chair of Siebert Financial Corp. said, "Mickie liked to say that she came to New York City 'with $500 and a used Studebaker.' She overcame tremendous challenges to become a legendary Wall Street trailblazer, recognized as the 'First Woman of Finance.' We are delighted Mickie's contributions have been acknowledged by the NYSE in such a historic way." The dedication of Siebert Hall is the first time a room at the NYSE, designated a National Historic Landmark in 1978, has been named after an individual. Hosted by Tom Farley, NYSE Group President, the room features memorabilia from Mickie Siebert's career gifted to the NYSE by the Estate of Muriel F. Siebert. "When Mickie became the first female member of the NYSE in 1967, she shattered a glass ceiling on Wall Street," said Farley. "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." Gloria E. Gebbia, owner and managing member of Kennedy Cabot Acquisition said, "Mickie Siebert was courageous, savvy and pioneering, both as a woman and as a business person. My family and I are proud and humbled to continue her professional and charitable legacy. We believe she would be very pleased that the Gebbia family shares her passion for worthwhile causes." Muriel Siebert, who died in 2013, was also a pioneer in the discount brokerage field, transforming her firm into a discount brokerage in 1975 on the first day NYSE members were allowed to negotiate commissions. In 1977, she put her firm in a blind trust to serve as New York State's first woman Superintendent of Banking for five years, and under her watch, not a single banking institution failed.
