Jankiel Wiernik
Polish holocaust survivor (1889–1972)

Jankiel (Yankel, Yaakov, or Jacob) Wiernik (Hebrew: יעקב ויירניק; 1889–1972) was a Polish-Jewish Holocaust survivor who was an influential figure in the Treblinka extermination camp resistance. He had been forced to work as a Sonderkommando slave worker there, where an estimated 700,000–900,000 people, mostly Jews, were murdered. After his escape during the uprising of 2 August 1943, Wiernik reached Warsaw and joined the resistance. He also wrote a clandestine account of the camp's operation, A Year in Treblinka, which was copied and translated for printing in London and the US in English and Yiddish.
Following World War II, Wiernik testified at Ludwig Fischer's trial in 1947. He left Poland, emigrating first to Sweden and then to the new state of Israel. In 1961, he testified at Adolf Eichmann's trial in Jerusalem. He returned to Poland in 1964, to attend the opening of the Treblinka Memorial. Wiernik died in Israel in 1972 at the age of 83.
Life
Wiernik grew up and lived with his family in Kobryń, Poland (then part of the Russian Empire), where he followed his father in becoming a master cabinetmaker.
This brief starts where responsible research should: with the source description of “Jankiel Wiernik” as polish holocaust survivor (1889–1972). Everything that follows is an evidence route, not borrowed authority.
Why this record matters

The linked authority identifier is Q6154832. VIAF identifies the subject as 70780932. The Library of Congress control number is n2004043634. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
