BUCHAREST, Romania — Maksim Goldenshteyn recounts a story his grandmother once told him about how, as a 4-year-old child, she snuck out of a Jewish ghetto during World War II to retrieve her favorite dolls that had been left behind when her family was forcibly evicted from their home in occupied Soviet Ukraine.

“She knew, even at that age, that because she had lighter hair and blue eyes, she could pass for a local Ukrainian girl,” said Goldenshteyn. “She put on a kerchief and slipped out of the ghetto.”

It’s one of the stories that Seattle native Goldenshteyn tells in his book, ” So They Remember,” which recounts — with a blend of intimate family memoir and historical research — the Holocaust in Transnistria, a territory in occupied southern Ukraine that was controlled by Romania, a close ally to Nazi Germany for most of the war.

In that territory, where around 150 camps and ghettos operated, there played out a lesser-known but equally sinister chapter of the Holocaust, where hundreds of thousands of Jews were brutalized, exploited, and murdered. Many died of starvation; some succumbed to disease or exposure; some were executed.

Goldenshteyn, 33, whose family moved to the U.S. from the former Soviet Union in 1992, says he heard fragments of his family’s past while growing up, but he never linked it to one of humanity’s darkest chapters.

“They didn’t really align with the image of the Holocaust that I thought was representative,” he said. Then, 10 years ago, his mother told him the story.

“I was shocked at first,” he said.

Moved by what he’d learned, Goldenshteyn embarked on a decade-long journey researching a part of the Holocaust he feels is largely overlooked.

His starting point was to interview his grandfather, Motl Braverman, in his Seattle home. Braverman, who died in 2015, languished as an adolescent with his family in the remote Pechera death camp.

“My grandfather spoke with a certain detachment, as if relating someone else’s experiences,” Goldenshteyn wrote. “Later, he assured me that the death camp he survived was never far from his mind.”

All of the comforts that his grandmother, Anna Braverman, had known while growing up “evaporated overnight,” when her family was imprisoned in a ghetto in Transnistria in 1941.

Awareness of Romania’s role in the Holocaust, at home and abroad, is far less than that of the Nazis’ role. But in Romanian-controlled territories under the military dictatorship of Ion Antonescu, between 280,000 and 380,000 Jews, plus some 12,000 Roma, were killed during the war. The decades of communism that followed all but erased memories of the Holocaust.

“I don’t think many people realize that Romania was Germany’s principal ally in the East,” Goldenshteyn said, adding that the country’s communist period under dictator Nicolae Ceausescu became the “traumatic history that is more immediate” to Romanians.

A late 2021 study by the National Institute for the Study of the Holocaust in Romania showed that 40% of respondents were not interested in the Holocaust. Nearly two-thirds of the 32% who agreed that the Holocaust took place in Romania mistakenly identified the deportation of Jews to “camps controlled by Nazi Germany.”

Stefan Cristian Ionescu, a historian and Holocaust expert at Northwestern University, said that most Romanians “think that it’s a responsibility of Nazi Germany.”

“I think a lot of Romanians still have a problem accepting that the Antonescu regime and the Romanian authorities … were involved in the Holocaust,” he said. “In the mass murder, deportation, and dispossession of Jews in Romania, and in occupied territories such as Transnistria.”

In a push for wider public awareness, Romanian lawmakers passed a bill last fall to add Holocaust education to the national school curriculum, a move that was applauded by many. But in January the far-right Alliance for Romanian Unity, which holds seats in parliament, called it a “minor topic” and an “ideological experiment.”

David Saranga, Israel’s ambassador to Romania, strongly condemned the party’s comments, saying such statements are “outright proof of either a lack of taking responsibility, or of ignorance.”

Goldenshteyn believes that Romanian authorities have made progress in recent years in acknowledging the country’s role in the Holocaust. He said he was troubled by the party’s comments but also encouraged by the reaction of the diplomatic community.

“It’s important for any country with a dark past to confront it,” said Goldenshteyn, the father of two small children. “Because it’s impossible to chart the way forward without knowing where you’ve been. There is not enough knowledge about what happened during the Holocaust in Eastern Europe.”
