From a New York Times obit by Daniel E. Slotnik headlined “Haim Roet, Who Kept Holocaust Victims’ Names Alive, Dies at 90”:

Rosina Roet. Adelheid Roet. Abraham Roet.

The names of three Dutch Jews and others who died in the Holocaust could have easily been lost to history, their individual humanity snuffed out under the overwhelming weight of six million victims.

Haim Roet, a relative, ensured that this never happened.

Mr. Roet, who survived the Holocaust by hiding in a Dutch village, came up with the simple but powerful idea of memorializing Jewish victims of the Nazis by intoning their names.
