He was also an award-winning educator and lecturer on the Holocaust. He witnessed the murders of friends and family, the people they were staying with, and some of his extended family, at a dinner table by the Gestapo. He was sent to nine concentration camps in Germany and occupied Poland.
Amazingly, he survived. At age 14, he was a fighter with Soviet partisans. Faber recalls seeing many horrible actions in the concentration camps, ranging from seeing a baby thrown into an oven to losing every friend he made in camp.
Faber also recalls the horrors of seeing most of his family dead. He remembers how an Italian friend named Finci ran into his father's arms and his father was shot right then (in front of him). When he was liberated from Bergen-Belsen in 1945, he was 18 years old and weighed 72 pounds.
Faber says "I was a living skeleton". He said he could not resist anymore, and as soon as he was liberated he gave up on living. He was found at the side of a road and taken to a hospital.
In the 1950s, he moved to the United States, working as a pastry chef in Springfield, Massachusetts, and being called to offer testimony against Nazi war criminals. Faber's book is required reading in some schools. He is buried in King David Lawn at Greenwood Memorial Park in San Diego.
