Artur Eisenbach (born April 7, 1906 in Nowy Sącz, died October 30, 1992 in Tel Aviv) was a Polish-Jewish historian; an expert on the history of Jews in Poland, member of Polish Academy of Sciences and the head of the Jewish Historical Institute in Warsaw between 1966 and 1968.
Eisenbach studied history briefly at the Jewish Educational Seminary in Vilna and then at the Warsaw University under Marceli Handelsman. Afterwards, he worked at the Society for Jewish Health Care in Poland (Towarzystwo Ochrony Zdrowia Ludności Żydowskiej w Polsce, TOZ).
He married the sister of a fellow historian, and later ghetto chronicler, Emanuel Ringelblum. After the Nazi invasion of Poland on September 1, 1939 Artur along with his wife and child escaped to his wife's hometown in the east, the small town of Buczacz (now Buchach, Ukraine). However, as a consequence of the Nazi-Soviet pact known as the Molotov-Ribbentrop Treaty, on September 17 the Soviet Union also invaded Poland and Buczacz fell within the Soviet occupation zone. Along with 1,200,000 other Poles, Artur Eisenbach was deported deep within the Soviet Union. His wife and daughter stayed behind. In July 1941, after the Nazi Germany attacked the Soviet Union, Buczacz was taken over by the Germans. Eisenbach's wife and daughter subsequently were murdered by the Nazis.
