Ms. Quint, who was a young child during the Holocaust, and Ms. Cycowicz, who was a young teenager, are part of a fading generation that can bear witness to the Nazi atrocities.
After arriving there on Wednesday, Mr. Biden donned a black kippa and met Yad Vashem’s chairman, Dani Dayan, a former settler leader who was Israel’s consul general in New York.
At a memorial ceremony, he is expected to rekindle the eternal flame and lay a wreath. A children’s choir will perform and a cantor will recite a Jewish prayer for the souls of the Nazis’ victims.
Accompanying him on the visit will be Israel’s president, Isaac Herzog; Prime Minister Yair Lapid, who is the son of a Holocaust survivor; Rabbi Israel Meir Lau, a former chief rabbi of Israel who is chairman of Yad Vashem’s council and himself a survivor; Secretary of State Antony J. Blinken; Jake Sullivan, Mr. Biden’s national security adviser; and Deborah Lipstadt, a renowned Holocaust historian who was recently appointed as the Biden administration’s special envoy to monitor and combat antisemitism.
