Alexander Avram
Overview of Romanian Jewish Surnames in the Old Kingdom of Romania​
Picture
Most Jews living in the Old Kingdom of Romania (former principalities of Moldavia and Walachia) used surnames common throughout European Jewry. There were two exceptions: one, a small concentration of Sephardic Jews in Walachia; the other: between 8% to 14% of the Jews in these territories adapted their surnames to Romanian patterns or adopted plain Romanian surnames. The presentation will try to analyze and categorize these specific surnames by giving examples and outlining their historical and sociological causes and implications.

Dr. Alexander Avram retired in 2025 as Director of the Hall of Names and the Central Database of Shoah Victims’ Names at Yad Vashem. He trained as a philologist and linguist with a Ph.D. in the History of the Jewish People from Bar-Ilan University, Israel. Alexander specializes in Holocaust victim research, Jewish onomastics (the study of the history and origin of personal names), and the history of Jewish presence in the Romanian Principalities, as well as coexistence and anti-Semitism in 19th-century Romania, and the Holocaust in Romania and Transnistria.

Dr. Avram is the author of the book: Historical Implications of Jewish Surnames in the Old Kingdom of Romania
