More than 60 years had passed before I found them. Dozens and dozens of letters written to my family during WWII- from total strangers- to tell my great-grandmother that her son had been captured and was being held as a POW. How did they know this? Well, it seems the short-wave radio had held all the answers. POWs were allowed to state their names and hometowns on the radio, and sometimes relay a short message to their families. Scores of Americans, listening to the German propaganda from so far away, heard my grandfather's information, and took it upon themselves to write to my great-grandmother. All of these dear people wanted to give my great-grandmother a measure of comfort to know her son was alive. That was only the beginning of my journey. The second edition of World War Radio Heroes: Letters of Compassionwas publishedin May 2013 with three times as much content and even more amazing stories.
