Messengers of Disaster – Raphael Lemkin, Jan Karski, and Twentieth–Century Genocides

Leading up to World War II, two Polish men witnessed the targeted extermination of Jews under Adolf Hitler and the German Reich before the reality of the Holocaust was widely known. Raphael Lemkin, a Jewish lawyer who coined the term "genocide," and Jan Karski, a Catholic member of the Polish resistance, independently shared this knowledge with Winston Churchill and Franklin D. Roosevelt. Having heard false rumors of wartime atrocities before, the leaders met the messengers with disbelief and inaction, leading to the eventual murder of more than six million people.

Messengers of Disaster draws upon little-known texts from an array of archives, including the International Committee of the Red Cross in Geneva and the International Tracing Service in Bad Arolsen. Carrying the knowledge of disaster took a toll on Lemkin and Karski, but their work prepared the way for the United Nations to unanimously adopt the first human rights convention in 1948 and influenced the language we use to talk about genocide today. Annette Becker's detailed study of these two important figures illuminates how distortions of fact can lead people to deny knowledge of what is happening in front of their own eyes.
