Abigail Pogrebin's immersive exploration of the Jewish calendar began with her popular 12-month series for the Forward. Now, in My Jewish Year: 18 Holidays, One Wondering Jew, Pogrebin has expanded her investigation-infusing it with more of her personal story and exposing each ritual's deeper layers of meaning.

Pogrebin is also the author of Stars of David: Prominent Jews Talk About Being Jewish, in which she discussed Jewish identity with 62 celebrated public figures ranging from Justice Ruth Bader Ginsburg to Steven Spielberg, from Mike Wallace to Natalie Portman. Pogrebin's second book, One and the Same, about the challenges of twinship, is grounded in her own experience as half of an identical pair. Most recently, she published "Showstopper," a bestselling Amazon Kindle Single that recalls her adventures as a 16-year-old cast member in the original Broadway production of Stephen Sondheim's flop-turned-cult-favorite, "Merrily We Roll Along."

Pogrebin's articles have appeared in Newsweek, New York magazine, The Daily Beast, Tablet, and many other publications. Pogrebin was formerly a producer for Ed Bradley and Mike Wallace at CBS News' 60 Minutes, where she was nominated for an Emmy. Before that, she produced for broadcasting pioneers Fred Friendly, Bill Moyers, and Charlie Rose at PBS.

A frequent speaker at synagogues and Jewish organizations around the country, Pogrebin has for seven years produced and moderated her own interview series at the JCC of Manhattan called "What Everyone's Talking About." Abigail Pogrebin lives in New York with her husband, David Shapiro, and their two teenage children.
