Muriel F. 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.
She began her career in finance working for various brokerages, and in 1967 began her own firm, beginning by doing research for institutions and buying and selling financial analyses. In 1975, Muriel Siebert and Company became the nation’s first discount broker, when the Securities and Exchange Commission first permitted broker commissions to be negotiable. In 1977, Siebert became the Superintendent of Banks for the State of New York, with oversight of all of the banks in the state, regulating about $500 billion.
In 1990 she created the Siebert Philanthropic Program, through which she shares half of her firm’s profits from new securities underwriting with charities of the issuers’ choices. The program offers buyers of new securities a chance to help charities in their communities.
