During the time the Nazis and Hitler attempting to terminate the Jewish people, these six killing centers were installed: Bernburg, Brandenburg, Grafeneck, Hadamar, Hartheim, and Sonnenstein. Within these centers, you would find small rooms that would be used for gas exposure killings. At the start of the Holocaust, the only resource they knew of to use was carbon monoxide. The Nazis would "constantly searched for more efficient means of extermination" (USHMM).
By September 1941, the Nazis had finally found a new way to fuel their gas chambers. Zyklon B. It was ten times as fast to kill the Jewish people. It had also been a big money saver for the Nazis. When they finally had installed it into their gas chambers, they had killed over 6000 Jews each day at Auschwitz.
This astounds me that people would be okay gassing out people, let alone children. I just found it so interesting that they had more than two or three types of ways to kill off the Jewish people, and I hope you do too.
