Born in the Netherlands, Jack was just a 15 year-old high school student when the Nazis occupied Europe. Repeatedly hunted by the Nazis, he escaped capture, an incredible ten times through strength, quick thinking and help from the Resistance.

As hiding places disappeared Jack managed to escape to France, where he became involved in espionage operations with the super secret, O.S.S. (Office of the Strategic Services - which later became the C.I.A.).
 

After completing a critical mission, the O.S.S. sent Jack to the United States to enlist in the U.S. Army C.I.C. (Counter Intelligence Corps). On Dday+2, Jack with his team of agents, landed on Utah Beach and advanced along U.S. forces that liberated France and moved into Germany. His duties were to locate, interrogate and arrest Nazi operatives and war criminals.
 

Jack's journey from hunted survivor to American intelligence agent reflects extraordinary resilience, courage, and determination. 

Throughout his life, Jack has dedicated himself to sharing the lessons of freedom, survival, and leadership with audiences around the world. As a Holocaust survivor, liberator, World War II veteran, speaker, and author, he continues to inspire future generations through his testimony and public appearances.
 

His story stands as a powerful reminder of the value of freedom and the strength of the human spirit in the face of tyranny and war.
