Józef Jędrzej Załuski

Józef Andrzej Załuski (12 January 1702 – 9 January 1774) was a Polish Catholic priest, Bishop of Kiev, a sponsor of learning and culture, and a renowned bibliophile. A member of the Polish nobility (szlachta), bearing the hereditary Junosza coat-of-arms, he is most famous as co-founder of the Załuski Library, one of the largest 18th-century book collections in the world.

Together with his brother Andrzej Stanisław Załuski he was raised by their uncles (Andrzej Chryzostom Załuski, bishop of Warmia, and Ludwik Załuski, bishop of Płock). Józef was educated in the Polish-Lithuanian Commonwealth (Warsaw, Gdańsk, Kraków) as well as abroad (Sorbonne in Paris). He took Holy Orders in 1727. In his career he was a Great Crown Referendary (referendarz wielki koronny) from 1728 and canon of Kraków. As a supporter of King Stanisław Leszczyński he accompanied him to France in the 1730s, where he was a royal chaplain on the royal court of Leszczyński's wife, Queen Katarzyna Opalińska. He controlled some of the Church's property in France; after his return to Poland he became the abbot of Wąchock. In 1759 he became the bishop of Kiev and in 1762 he led the synod of the diocese.
