Louis Fogelman was born in 1941 in Hilversum, the Netherlands. When he was about a year old, his parents tried to escape with him to Switzerland, but they were betrayed by a family friend who turned them into the Gestapo. Louis and his parents were sent to the Hollandsche Schouwburg, known during the war as the “Jewish Theater,” where Jews were detained before deportation. At the Theater, an underground organization smuggled Louis out and took him to his paternal grandparents. Afraid to keep him, his grandparents sent him to his non-Jewish aunt in Hilversum. He spent the rest of the war in hiding. After the war, he reconnected with his father's sister Betty. In 1948, they immigrated to the United States.
