Yahad-In Unum Holocaust by Bullets Exhibit
Sunday, December 2nd
10 am- noon
Boulder JCC
No Charge

The Holocaust by Bullets exhibit focuses on the mass shootings of Jews and others that took place throughout Eastern Europe by the Nazi mobile killing units from 1941 to 1944—and the mechanisms of mass violence generally. It pays homage to the memories of the victims while seeking to promote a proactive movement against genocide.
About Yahad-In Unum
Founded in 2004, Yahad-In Unum is a global humanitarian organization dedicated to identifying and commemorating the sites of Jewish and Roma mass executions in Eastern Europe during WWII and educating about genocide prevention. Yahad-In Unum’s Founder and President, Father Patrick Desbois, has devoted his life to researching the Holocaust, fighting anti-Semitism, and furthering relations between Catholics and Jews. In identifying and documenting the Holocaust by Bullets, Yahad-In Unum has recorded the testimonies of thousands of participants and witnesses to these events. Through 14 years of fieldwork, Yahad-In Unum has identified over 1,460 execution sites, 2,487 mass graves, and recorded 6,098 testimonies.
