Formed in 1951, Louis and Anne Abrons Foundation is a private grantmaking foundation established by the late Louis W. Abrons, a New York City property developer from the early 20th century.  The foundation supports performing arts initiatives, humanitarian projects, and left-of-center advocacy organizations in New York and around the United States.  
The Louis and Anne Abrons Foundation is a private foundation founded by the late Louis W. Abrons. Born in Russia, Abrons and his parents moved to the United States in the late 1800s. From the 1920s to the 1930s, he made a large fortune running a New York City construction company.  In 1951, Abrons established his own grantmaking foundation, known as the Louis and Anne Abrons Foundation. Since his death in 1977, the foundation has been managed by his family; but it continues to be funded by Abrons’ estate.   The foundation is known for supporting the arts in New York City; it is a key donor of the Henry Street Settlement, a social services charity that also operates the Abrons Arts Center. 
Backing Left-Wing Causes
In addition to its conventional charitable activities, the Louis and Anne Abrons Foundation has supported many left-wing organizations, primarily in the areas of social liberal advocacy, and environmentalism. 
The foundation supports several “pro-choice” advocacy groups and women’s medical clinics that provide abortion services. In 2017 alone, it backed the Planned Parenthood Federation of America with an unrestricted grant of $250,000. During the same year, the foundation donated almost $137,000 to affiliates of the group, including Planned Parenthood of Northern New England, Planned Parenthood of Michigan, and Planned Parenthood Hudson Peconic. 
According to its most recent tax filing, the Louis and Anne Abrons Foundation has approximately $143 million in assets. 
Today, the foundation’s leadership consists of Louis Abrons’ children and a few close relatives. Peter and Leslie Abrons, Louis’s children, are the co-presidents of the organization and both serve on the board of directors. Meanwhile, their brother and fellow board member, Henry L. Abrons, is the foundation’s treasurer.
