About the Book
The incredible true account of a young Jewish student who, in a desperate gambit to escape the Nazis, went underground in his hometown of Berlin, posing as an Aryan with another young escapee—a harrowing ordeal that he would miraculously escape not only with his life, but also with a love that would last a lifetime.
In 1933, the year that Hitler seized power in Germany, Ernest Fontheim was a bookish and playful 11-year-old, leading a charmed existence in Berlin with his assimilated upper-class Jewish family. In less than a decade, the Fontheims’ fortunes irrevocably changed: By 1941, Ernest’s father had been stripped of his law license, their luxurious apartment had been usurped by a Nazi official, and Ernest, now 19, had been forced into labor at the Siemens munitions factory. First his girlfriend, then his best friend, and then his entire immediate family were “deported to the East,” sent to fates unknown.
Finally, in desperation, Ernest approached his friend at Siemens, the charming Margot Hass, with a plan: along with her parents, they would go underground, posing as an Aryan family in order to avoid the roundups. Ernest and the Hasses soon joined the ranks of the roughly 6,500 Berlin Jews who went into hiding after deportations to the camps began. Most of the invisibles were caught within the first few weeks or months. But incredibly, this little group—joined by fate and by choice—would survive not only the terror of the war but also the chaos of its aftermath, when Ernest found himself facing death on numerous occasions at the hands of their Soviet liberators.
Based on a five volume-diary kept by Ernest throughout the war,The Boy Who Vanished is an instant classic; the stunning tale of a young man’s struggle to hold onto his humanity in a country gone mad—and his unlikely triumph over the forces of darkness.

Advance Praise for The Boy Who Vanished
"Written in vivid narrative prose, Ernest Fontheim's story unfolds like scenes from a movie. His odyssey of coming of age underground as a Jewish student in wartime Germany, evading bloodthirsty Nazis on a daily basis, and navigating Berlin’s treacherous black market also exemplifies the courage and luck necessary to overcome a government bent on genocide. Hard to put down, The Boy Who Vanished is a testament to the commitment of a man and his community to freedom, interwoven with a wistful tale of triumph over unimaginable loss."
— Keren Blankfeld, author of Lovers in Auschwitz: A True Story
"The Boy Who Vanished presents an engrossing and intimate account of the complexities, vigilance, never-ending ingenuity, and constant performance required for an underground Jew to evade detection in the Third Reich. A deeply personal and profoundly affecting read which takes seriously the importance of artistic and cultural resistance, The Boy Who Vanished is necessary reading for anyone confronting the realities of life in an authoritarian state."
— Elizabeth Hyman, New York Times bestselling author of The Girl Bandits of the Warsaw Ghetto: The True Story of Five Courageous Young Women Who Sparked an Uprising
"An extraordinary tale of survival, resilience, and courage - and a book that couldn’t have arrived at a more crucial time."
— David Litt, New York Times bestselling author of It’s Only Drowning; Democracy in One Book or Less; and Thanks, Obama
“From the challenges of using fake IDs and finding food on the black market to the hair-raising experience of being marked and chased on foot through Nazi Berlin, The Boy Who Vanished reminds us that survival is a community effort requiring ingenuity, tenacity, and a lot of luck. Ernest Fontheim’s unique and harrowing story draws you in starting on the very first page. You will read this book, cover to cover, in one sitting.”
— Heather Dune Macadam, author of 999 and Star Crossed
