Aron Bielski
Aron Bielski (born July 21, 1927), later changed to Aron Bell, is a Polish-American Jew and former member of the Bielski partisans group, the largest armed rescuers of Jews by Jews during World War II. He was also known as Arczyk Bielski. The youngest of the four Bielski brothers, he is the only one still living (Asael died in 1945, Tuvia in 1987, and Alexander ["Zus"] in 1995).

Life with the Bielski partisans
The Bielski family were farmers in Stankiewicze near Navahrudak in present-day Belarus, an area that at the beginning of the Second World War belonged to the Second Polish Republic. In September 1939, it was seized by the Soviet Union, which was then allied with Nazi Germany. After the Germans launched Operation Barbarossa, the invasion on the Soviet Union, Aron's brothers created a notable resistance organization, the Bielski partisans group. Aron became a member of that group.

Nechama Tec, who wrote a book about them, had the following to say about Aron: "Occasionally in the forest he acted as a guide. Those I spoke to agree that his participation and impact on the life of the Bielski otriad [a partisan detachment] was minimal, almost nonexistent." While Nechama was not able to interview Aron, he was interviewed by Peter Duffy in Duffy's book.
That author, in the second authoritative book about the Bielski partisans, mentions Aron about 30 times and lists him as one of the important sources for the book.  Duffy also interviewed Bell for the article "Heroes Among Us" (2000), published in The New York Times.

Later life
After the war, Bielski returned to communist-dominated Poland but soon afterward emigrated to the British Mandate of Palestine. In 1954, he settled in the United States of America, where he joined his surviving brothers and their families. He  drove and then owned two trucks in New York City. Aron is the only member of the Bielski family to have changed his family name.

Legacy
George MacKay portrayed Aron in the film Defiance (2008).
