The brothers established Ziff Brothers Investments and significantly increased their inherited fortunes. Leslie Ziff holds a BFA in dance from Cornish College of the Arts. The couple is divorced.


PERFORMING ARTS: Daniel Ziff is a longtime supporter of performing arts in New York City. He began supporting Lincoln Center for the Performing Arts in 1997, and since then his gifts to the institution have increased to about $1 million each year. Leslie Ziff has served on the board of trustees of the American Ballet Theater and Rosie’s Theater Kids, Rosie O’Donnell’s performing arts program for students from New York City’s “neediest elementary schools.” Additional past grantees include Mark DeGarmo Dance, the Polaris Dance Theatre, Sing for Hope, the New York Philharmonic, Carnegie Hall, and the Metropolitan Opera.

LOOKING FORWARD: The fate of the Leslie and Daniel Ziff foundation is unclear in light of the couple’s divorce.
