siebertSiebert Financial Corp. is leaning on Rubenstein Associates to handle PR through the death of founder Muriel "Mickie" Siebert, the pioneering Wall Street woman and SFC chief who died Aug. 24.

Rubenstein senior VP Laura Hynes-Keller and senior executive VP Marcia Horowitz are handling Siebert, a long-time agency client.

Siebert was the first woman to own a seat on the New York Stock Exchange and first to head a member firm. She also was Superintendent of Banking for New York State for five years and an innovator in the discount brokerage field in the mid-1970s.

She founded and led SFC until her death in New York on Saturday from complications from cancer.

Joseph Ramos, COO and principal executive officer of the brokerage, will continue a role similar to Seibert, the company said.

"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," Ramos said in a statement. "We will work to continue her legacy."
