correction
An earlier version of this article incorrectly said that on the eve of the 1941 Nazi invasion, Ukraine had the largest Jewish population in Europe, based on inaccurate information from the U.S. Holocaust Museum. The article has been updated.
In 1941, when the Nazis were closing in on Kyiv, Gdalina Novitsky was 3. She recalls her parents listening to the radio, trying to decide what to do. Like many children fleeing from Ukraine today, she had to part from her father, who went to fight in the Soviet army.
“I remember how he put on his military uniform and he cried, my mom cried, I cried,” said Novitsky, who now lives in Wheeling, Illinois.
