(SIEB) Announces Death of Founder Muriel F. “Mickie” Siebert

In 1967 She Became First Woman Member of New York Stock Exchange; In 1977 First Woman Superintendent of Banking for New York State

Siebert Financial Corporation (Nasdaq: SIEB) and its wholly-owned subsidiary, Muriel Siebert & Co., Inc., are saddened to announce the death of Muriel F. “Mickie” Siebert, Founder, Chairwoman and Chief Executive Officer. Ms. Siebert, 80, died of complications from cancer at Memorial Sloan-Kettering in Manhattan on Saturday, August 24. Joseph M. Ramos, the Company’s Chief Operating Officer, as principal executive officer, will continue performing a similar function to those performed by Ms. Siebert.

Best known as the first woman to own a seat on the New York Stock Exchange and the first to head one of its member firms, Ms. Siebert 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. A champion for the rights of women and individual investors and a strong voice for sound business practices in the financial service industry, Ms. Siebert was frequently quoted in the press, wrote opinion pieces for major media outlets and testified before Congress. Through the Muriel F. Siebert Foundation, she developed the “Siebert Personal Finance Program: Taking Control of Your Financial Future,” a financial literacy program to teach basic financial skills to middle and high school students and adults. As recently as 2010, she was named by U.S. Banker Magazine as one of the “25 Most Powerful Women in Finance.

“This is obviously a great loss not only for our company but for the financial industry in general, “said Mr. Ramos. “Mickie was a pioneer and recognized as a leader throughout the industry and beyond. She was respected as a strong voice of integrity, reason and sound business practices. Although she is best known as the first woman to own a seat on the NYSE, she really became one of the great personalities on Wall Street of either sex. Those of us who worked with her will miss her spirit, leadership and great commitment to her clients and the securities markets. We will work to continue her legacy.”
