Danny, based in Israel, authors family legacy books, preserving the lives, memories and values of parents for their grandchildren, great grandchildren and beyond. He wrote a book about his own grandfather (who was present at the liberation of Bergen-Belsen) and has translated and ghostwritten a number of Holocaust memoirs. He has also penned an ebook about coping with stress (based on his Israeli Army experiences and being a parent of a child with cancer), and has published articles on aish.com, chabad.org and The Jewish Press, among others.
I believe every family should have some written or visual record of their ancestors. Otherwise the memories will be lost within one or two generations.
