He was born in Działoszyce and was a prisoner in the Płaszów camp. After the war, he emigrated with his family to Palestine. He testified as a witness at the Eichmann trial and became one of the leading participants in the national debate on the memory of the Holocaust. In 1970, he was appointed as the second chairman of the Commission for the Righteous at the Yad Vashem Institute, after Justice Moshe Landau, and remained in this position for a quarter of a century. During this time, almost eighteen thousand people were honored with the title Righteous Among the Nations. Trees were planted in the alley at Yad Vashem to commemorate their deeds. Thanks to the diligence and dedication of Moshe Bejski, the search for and commemoration of the Righteous became one of the fundamental tasks of the Institute, alongside collecting data on the victims and perpetrators, as well as Holocaust education. We owe to him the methodology for verifying applications, the adoption of decision-making criteria, and the recognition of popularizing the memory of the Righteous as a fundamental element of Holocaust remembrance.
