The Righteous are not only people who sacrificed themselves or risked their lives to save other people victims of racism, anti-Semitism and violence, but also those who made the Truth known about what was happening and did happen and fought to keep alive the Memory of the facts and people who were victims of Evil, as well as those who fought it.
These are witnesses, historians, intellectuals who, risking their lives, their freedom, their careers, made sure that truth was known and not forgotten.
