Wojciech Kętrzyński (born Adalbert von Winkler; 11 July 1838 – 15 January 1918), was a Polish historian and the director of the Ossolineum Library in Lemberg, then the capital of Galicia, Austrian Empire.In 1856 his sister had discovered the family's ancestry and informed him about it, which caused his decision to identify himself as a Pole, even though he did not read or write Polish and knew only a few words and expressions.[1] In 1863 he was imprisoned for his support of the Polish January Uprising in the Russian partition and spent his jail time in Olsztyn (Allenstein), Berlin, and Kłodzko (Glatz).[1] After being released from prison, Kętrzyński completed his doctorate at the university of Königsberg (Królewiec) and moved to the Kingdom of Galicia and Lodomeria (the Austrian Partition of Poland) within Austria-Hungary to pursue his interests.In recognition of his deeds after World War II, the town of Rastenburg in Masuria, after conquest by the Soviets, (Polish: Rastembork) was renamed Kętrzyn after Kętrzyński in 1946.
