Manfred Lindenbaum, who lost members of his family in the Holocaust, will speak at Wednesday's "Yom HaShoah" commemoration in Niskayauna.
Lindenbaum, who lives in Jackson, New Jersey, will speak at Congregation Agudat Achim, at 2911 Union St., beginning at 7:30 p.m.
"Yom HaShoah" also is known as Holocaust Remembrance Day.
Lindenbaum and his family became refugees in 1938, forced by the Nazis to leave their home in Germany. They fled over the border into neighboring Poland.
They were denied entry into Poland, so the family lived for a year in the border town of Zbaszyn. In 1939, when Lindenbaum was 6, he and his brother boarded the last of the boats known as the Kindertransport.
Lindenbaum's older sister Ruth was deemed too old for that escape. Ruth and the Lindenbaum parents later were murdered in Auschwitz.
Lindenbaum, to preserve his sister's memory, has spent much of his free time teaching about the Holocaust and devoting himself to the cause of refugees throughout the world.
The commemoration also will feature community prayers and readings led by rabbis of the Schenectady synagogues, and a lighting of candles in memory of the 6 million Jews killed by the Nazis.
The public is invited.
