Sylvia is Lou's younger sister. She was born January 30, 1918. As a child, she could outrun Lou when he was angry at her and chasing her. She died in 2008. Laura got a lot of the information for the book from long phone conversations with Sylvia. In the book there are pictures of Sylvia with her husband, Harvey Flammer (also a WWII soldier-- he was a tank driver who fought in the Battle of the Bulge and earned the Bronze Star).
