Muriel Siebert, who became a legend on Wall Street as the first woman to buy a seat on the New York Stock Exchange and the first woman to head one of the exchange’s member firms, died on Saturday in Manhattan. She was 84.
The cause was complications of cancer, said Jane H. Macon, a friend and board member of Ms. Siebert’s firm, the Siebert Financial Corporation.
Ms. Siebert, known to all as Mickie, cultivated the same brash attitude that characterized Wall Street’s most successful men. She bought her seat on the exchange in 1967, but to her immense anger, she remained the only woman admitted to membership for almost a decade.
She was one of the pioneers in the discount brokerage field, as she transformed Muriel Siebert & Company (now a subsidiary of Siebert Financial) into a discount brokerage in 1975, on the first day that Big Board members were allowed to negotiate commissions.
She also was the first woman to be superintendent of banking for New York State, appointed by Gov. Hugh Carey in 1977. She served five years during a rocky time when banks were tottering and interest rates were skyrocketing.
