THE first woman to hold a seat on the New York Stock Exchange left $US100,000 ($107,000) in her will to care for her beloved chihuahua "Monster Girl", plus millions more for the "humane support of animals."

Muriel Siebert, who died of cancer at age 84 in August, gave friend Lynda Fox-Frazer in New York $US100,000 to care for her pooch, the New York Post reports.

"I request that my dog not be left alone for long periods of time during the day," the Wall Street icon writes in her will, filed in Manhattan Surrogate’s Court today.

She also gave $US10,000 to The Animal Medical Centre in Manhattan, to be gifted while Monster Girl is still living.The never married, childless Siebert left a $US48 million fortune, according to filings in Manhattan Surrogates Court.

The majority of the cash will go to the Muriel F. Siebert Foundation, which "supports the furtherance of education in personal financial literacy and the humane support of animals," specifically animals "owned by the elderly who are financially challenged,” states the will.

The trailblazer, who first muscled her way into the boy’s club of Wall Street in 1967 buying a spot for $US445,000, was left her sister $US 1.5 million and was also very generous to her friends, giving them cash and jewellery.
