Козимо III Медичи
Teodor and his brother Krzysztof Lubieniecki hailed from Arian family. They learned to paint from Juriaan Stur in Hamburg. In 1667 they travelled to Amsterdam, where Krzysztof apprenticed with Adriaen Backer, and Teodor with Gerard de Lairesse. Teodor enjoyed success in Amsterdam and was visited and admired by Cosimo III de' Medici, Grand Duke of Tuscany who was visiting Amsterdam while on his Grand Tour up the Rhine. In 1682, Teodor moved to Hannover where he found work for the art-loving Frederick William I, Elector of Brandenburg. His son Frederick I of Prussia made Lubieniecki the first curator of his Akademie der Künste in 1702. In 1706 Lubieniecki moved to Poland, which is where he later died.
