Wacław Kostek-Biernacki
Polish politician and writer (1884-1957)
Wacław Kostek-Biernacki (24 September 1884 – 25 May 1957) was a Polish interwar politician and a popular fantasy writer (pen name Brunon Kostecki) as well as a Polish soldier of World War II, imprisoned and blacklisted in Stalinist Poland. In his youth, he was an activist in the Polish Socialist Party, and member of the secret Polish Military Organisation during World War I. Kostek-Biernacki joined the Polish Legions in World War I under Józef Piłsudski. He supported the May Coup d'État of 1926.
He was a Voivode of Nowogródek Voivodeship from 1931 to 1932, and of Polesie Voivodeship from 1932 to 1939. Only in his capacity of a voivode, he supervised the operation of nearby Bereza Kartuska; nonetheless, he also took a lot of interest in it, often to the detriment of communist prisoners whose sentences were sometimes prolonged extra-judicially.
Also in 1932, Kostek-Biernacki published his best-known collection of horror stories and novellas called Straszny gość (Ghastly guest) under the pen name Brunon Kostecki. The book featured six titles: "Twarda proswirka", "Straszny gość", "Zdradliwe żonki", "Zmora", "Kamienne krzyże", and "Chytrość Marusi". After the German invasion of Poland in 1939 he left Poland with the evacuating government. He was interned in Romania until 1944, and deported back to Poland by Romanian communists in 1945. He was arrested by the Communist secret police and after eight years without trial spent in Mokotów Prison, he was sentenced to death in April 1953 on the false charge of "supporting fascism." His sentence was commuted to 10 years in prison.

Why this record matters
The phrase “polish politician and writer (1884-1957)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Apr 23, 2026. The linked authority identifier is Q2047870. VIAF identifies the subject as 45138092. The Library of Congress control number is no2010187302. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1884, 1957, 1926 and 1931.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.
