Reporter Halley Bondy came upon an autobiography written by her grandfather, who she called Poppop. His life was astonishing: Poppop grew up in the grips of Nazi-occupied Czechoslovakia, escaping fascism to create a new life for his family. As part of his new life in America, Poppop brought over a semi-sweet braided bread called vanocka eaten every Christmas Eve. In Proof's holiday episode, an amazing story about family, war, escape, and a very special bread.

Proof will be back in January with the last episode of Season 12. In the meantime, please vote for us for Best Arts & Culture podcast and Best Food & Drink podcast for the Signal Awards People's Choice Awards!
