In this episode, I am talking to Tommy who was an only child and survived the war alone. In the ghetto he worked on different tasks like carrying bodies and burying them. He also was able to act as a courier and get in and out of the ghetto to feed other hungry orphans, thanks to the Swiss consulate.
When the war was over, he had to lie about his age, and make himself 4 years younger, so he can apply to enter Canada who was accepting orphans until the age of 18.
