I’ve listed various web sites and organizations that are relevant to Henry’s story, the time period, or Polish culture. Living Kraków Cultural Pilgrimages was invaluable in helping me plan my trip to Poland in 2013.
I am also very appreciative to Dr. Wojciech Płosa of the Auschwitz-Birkenau Museum, as well as Torsten Jugl of Buchenwald Concentration Camp for their assistance in helping me search their respective archives.
