The Firedoll Foundation is a private family foundation founded by community activists and liberal donors Sandor and Faye Straus. The foundation supports a number of left-of-center advocacy organizations. 
The Firedoll Foundation is largely funded by the Straus Family Trust and provides grants to groups that engage in community development and entrepreneurship, as well as those working on immigrant issues, human rights, environmentalism, and far-left policy toward the Middle East. 
Firedoll Foundation financially supports a number of pro-Palestinian and anti-Israeli advocacy organizations, including the Palestine Children’s Relief Fund (PCRF). PCRF has ties to the Holy Land Foundation, an organization alleged to have funded the terrorist organization Hamas. 
As for advocating for immigrant issues and human rights, since 2008 the Firedoll Foundation has donated to the Alliance for Global Justice, an organization that funds numerous left-wing groups which also serves as a fiscal sponsor for left-wing social initiatives and supports authoritarian governments in Latin America. 
Sandor Straus and Faye Straus met while campaigning for Senator Eugene McCarthy’s (D-MN) bid for the Democratic Presidential nomination in 1968. Faye received her B.A. in political science from the University of California, Berkeley, and Sandor received a Ph.D. in mathematics from Berkeley, going on to teach mathematics and computer science at NYU Stony Brook. Sandor later became involved in financial modeling and financial investments in the 1980s with Renaissance Technologies, a hedge fund known for its founder James Simons who himself is renowned for his contributions to the mathematical modeling of investments. 
While employed for Renaissance, Sandor worked at the Medallion Fund, Renaissance’s most profitable portfolio and a fund known for having one of the best records in investing history.  While at Medallion, Straus shepherded the fund out of a series of losses during the 1980s and eventually helped to create investment returns of 39.4 percent in 1991, 34 percent in 1992 and 39.1 percent in 1993.  Straus later cofounded his own investment firm, Merfin LLC, which was merged with Edgestream Partners in 2012 and relocated to New Jersey.
Since 199,4 Sandor Straus and Faye Straus have made individual donations respectively totaling $1,674,227.60 and $678,160 to various liberal organizations and Democratic candidates. These include donations to presidential and congressional candidates, the Democratic Congressional Campaign Committee, and groups such as the League of Conservation Voters Action Fund and Indivisible Action.
