The diary of the notorious Josef Mengele is set to be auctioned off in the United States.

Nazi memorabilia collectors vying for the artifact belonging to the Nazi doctor known at Auschwitz as the “Angel of Death” are expected to pay about $64,000, according to the Daily Mail.

The owner of the diary acquired the volume in Brazil after Mengele died there in 1979, the newspaper said. The historical artifacts house Alexander Autographs in Connecticut told the newspaper that the owner is a source close to the Mengele family.

The diary begins in May 1960, when Mengele was 49.

At Auschwitz, Mengele determined who would live and die, and he conducted horrific, quasi-medical experiments, including on twins.

News of the auction has prompted anger and revulsion among Holocaust survivors and their families, according to a statement released Monday by The American Gathering of Holocaust Survivors and Their Descendants.

“This is a cynical act of exploitation aimed at profiting from the writings of one of the most heinous Nazi criminals,” the statement said. “If the auction house will not halt the sale, we are calling on Connecticut Attorney General Richard Blumenthal to determine if he has the means to do so.”
