Muriel Siebert (Muriel Siebert)

Muriel Siebert

Siebert began her career working at various brokerages. In 1967, she founded her own eponymous firm, Muriel Siebert & Co., Inc., beginning by doing research for institutions, and buying and selling financial analyses. That same year, she applied for a seat on the New York Stock Exchange. Of the first ten men she asked to sponsor her application, nine denied her.

The NYSE itself insisted on a new condition before considering Siebert’s application. It insisted that Siebert obtain a letter from a bank offering loans of $300,000 at the near record $445,000 seat price. But banks would not commit to lend her the money until the NYSE would agree to admit her. Siebert finally was elected to membership on December 28, 1967. In 1975, when the Securities and Exchange Commission first permitted broker commissions to be negotiable, she criticized the discount brokers vehemently; she ran numerous ads calling the discounters and the rates “low ball”. In 1977, she was named Superintendent of Banks for the State of New York, with oversight of all of the banks in the state, regulating about $500 billion. Not one bank failed during her tenure, despite failures nationwide. When she learned Hugh Carey, New York Governor at the time had appointed her to the position, Siebert recalled thinking, “Mickie, you know you’re a college dropout. You’ve done pretty well as a college dropout!”

Shortly after returning to her firm, she ran in the Republican primary for the Senate seat of Daniel Patrick Moynihan. She finished second behind State Assemblywoman Florence Sullivan, who went on to lose to Moynihan in November 1982. In the mid-1990s, Siebert & Co. merged into a furniture holding company, J. Michael & Sons, that was liquidating, thereby becoming a publicly traded company. Siebert remained President of her eponymous firm, and continued to be a sought after commentor on phenomena in financial markets.

Siebert was an outspoken advocate for women and minorities in industry. She was quoted as saying, “American business will find that women executives can be a strong competitive weapon against Japan and Germany and other countries that still limit their executive talent pool to the male 50 percent of their population,” as well as “men at the top of industry and government should be more willing to risk sharing leadership with women and minority members who are not merely clones of their white male buddies. In these fast-changing times we need the different viewpoints and experiences, we need the enlarged talent bank. The real risk lies in continuing to do things the way they’ve always been done.”

In 1990, she created the Siebert Entrepreneurial Philanthropic Plan, through which she shared 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. Through 2006, more than $5 million has been contributed through this program. She served as president of the New York Women’s Agenda in 1998. During her term NYWA developed a program advocating “Financial Literacy for Women”, which continued until her death.   She sat on the boards of several philanthropies including The Economic Club of New York, The New York State Business Council, the Greater New York Council of the Boy Scouts of America, and the Guild Hall Museum, and others.

In honor of Siebert’s 30th anniversary on the New York Stock Exchange, she rang the closing bell on January 5, 1998. Likewise, on December 28, 2007, exactly 40 years after her election to the membership of the New York Stock Exchange, she rang the closing bell in celebration.  Siebert was a member of the National Women’s Hall of Fame, and was interviewed in the 2003 documentary Risk/Reward. She has been awarded 17 honorary doctorates. Siebert was inducted into the Junior Achievement U.S. Business Hall of Fame in 2009. She was honored at Wagner College during the 123rd Graduation Ceremony on May 21, 2010, with an Honorary Doctorate.

Siebert was born in Cleveland, Ohio on September 12, 1928. She attended Western Reserve University (now Case Western Reserve University) from 1949 to 1952, but left without graduating when her father fell ill. She never married or had children.  On August 24, 2013, Siebert died, aged 84, from complications from cancer at Memorial Sloan-Kettering Cancer Center. She is survived by her sister, Elaine Siebert.
