Known as the trial of the century, the case against the the former SS man was brought to court on April 11, 1961. It attracted international attention: Adolf Eichmann was one of the people responsible for the murder of an estimated six million Jews and Sinti and Roma in Europe. As court witnesses, Holocaust survivors described the horrific crimes committed during the Nazi era. For most of the survivors who testified, this was the first time they had spoken out about what had happened to them. Their accounts of murder, torture and manslaughter were devastating.
