In the early '60's a college drop-out left  Cleveland, Ohio and moved to New York City determined to find a career. She was interested in business and the stock market in particular. The problem was, women had  very limited roles they could play in Wall Street finance.
Muriel Seibert knew the importance and value of information in the Wall Street game of high finance. She became a top industry annalist, specializing in the aviation and entertainment markets. When she began getting calls from major institutional buyers who wanted to place orders she knew it was time to get her own brokers license.
In 1967 Seibert made history by becoming the first woman to purchase a seat on the New York Stock Exchange. She founded her own brokerage, Muriel Seibert & Co. in 1970. Between 1977 and 1987 she served as the New York State Superintendent of Banks.
By February of 1996, Wall Street's top woman executive, could see where brokerage services were headed. To fund the move to discount brokerage services and internet trading Seibert took her brokerage firm public. Utilizing a reverse merger with J. Michaels Inc., a defunct, but publicly traded Brooklyn furniture company, the firm of Muriel Siebert & Co., Inc. (SIEB) was created. By 1999, Seibert's company was rated the number one discount brokerage by Money Magazine (June '99). Her company's stock reached a 52 week high of over $70 per share.
