Personal life
Zuckerman became a US citizen in 1977.
Before marrying, Zuckerman's dating history included writers Betty Rollin, Nora Ephron, Arianna Stassinopoulos Huffington and a four-year relationship with feminist activist Gloria Steinem in the late 1980s, early 1990s.
In 1996 Zuckerman married Marla Prather, a curator of the National Gallery of Art. He and Prather have a daughter, Abigail, together. The couple divorced in 2001, and Prather later married lawyer Jonathan D. Schiller. Zuckerman's second daughter, Renee Esther, was born on December 19, 2008. Zuckerman was 71 at the time; the mother has not been identified.
On the November 28, 2014, episode of The McLaughlin Group, Zuckerman said he was a vegan and has been since 2008, confirming what in November 2010 had been published in Bloomberg Businessweek, "The Rise of the Power Vegans." Zuckerman last appeared on The McLaughlin Group on July 31, 2015, making a case for Texas governor Rick Perry's presidential run during that episode. A day later Zuckerman issued a statement that he would not be appearing at the East Hampton Artists-Writers softball game, the first time he would miss the game since 1993. The same month, the New York Post reported he turned over the sale of the New York Daily News to his nephews and has commented minimally on its dissolution.
Zuckerman contributed to a birthday book of letters for Jeffrey Epstein’s 50th birthday, along with a host of other notable names. Zuckerman was identified as one of Jeffrey Epstein's clients, paying Epstein millions of dollars for estate planning and financial services between 2013 and 2015, years after Epstein's conviction for child sex crimes.
