Sifting through the stacks of her local library in Hamburg, Germany, Jennifer Teege happened upon a book that first fascinated and then staggered her. Recognizing photos of her mother and grandmother, she made the horrifying discovery that her grandfather was Amon Goeth – the vicious Nazi commandant chillingly depicted by Ralph Fiennes in Schindler’s List.

The more Teege read, the more certain she became: If Goeth had met her, a German-Nigerian black woman, he would have killed her.

Teege, who was given up by her mother when very young, sits down with the Library’s Kaite Stover during National Library Week for a public conversation about the revelation and Teege’s subsequent quest to unearth and fully comprehend her family’s haunted history. She chronicles the story in her book with award-winning journalist Nikola Sellmair.
