Steven Pressman’s “50 Children: One Ordinary American Couple’s Extraordinary Rescue Mission into the Heart of Nazi Germany” will be released April 22, to coincide with Holocaust Remembrance Day on April 28.

His book tells the story of how Gilbert and Eleanor Kraus of Philadelphia rescued 50 Jewish children just as the doors to Jewish emigration from Europe were closing. It was the subject of a one-hour documentary that premiered a year ago on HBO. Pressman, an S.F.-based journalist, also directed the documentary.

He learned about the rescue mission when his wife, Liz Perle, showed him an unpublished manuscript by her grandmother, Eleanor Kraus.

Pressman will talk about “50 Children” at 7 p.m. April 28 at Books Inc. Opera Plaza, 601 Van Ness Ave., S.F. and 7 p.m. April 29 at Book Passage, 51 Tamal Vista Blvd., Corte Madera. A full listing of upcoming talks can be found at www.tinyurl.com/mymzwfe.
