Esther Shaya is the author of two prior books, both published exclusively in Dutch - Harry & Sieny: Surviving in Resistance and Love and Just Wait: The Heroic Life of Henriette Pimentel. Shaya has been a board member, editor, and author of the "Jewish Houses Foundation" since 2015. This foundation publishes a book per year with pre-war stories about the Jewish community in the Netherlands. Shaya has been interviewed on national radio and TV and has been a guest speaker about the crèche numerous times in the Netherlands, U.S., and Australia. As she conducted the interviews, Esther learned that her grandparents had sheltered children from the nursery.

As the granddaughter of Eastern-European, Jewish immigrants - some of whom came through the Netherlands - Susan B. Katz is deeply dedicated to keeping Holocaust stories alive. Katz is an award-winning, bestselling author of dozens of children's books; her body of work includes biographies of The Story of Jane Goodall, The Story of Albert Einstein and The Story of Ruth Bader Ginsburg (all bestsellers), among others. Susan also launched and ran Facebook and Instagram's author verticals. Angels of Amsterdam is her first work of narrative non-fiction for adults.
