and former monasteries entered into state hands. King Ludwig I of Bavaria collected especially Early German and Early Dutch paintings but also masterpieces of the Italian renaissance. In 1827 he acquired the collection Boisserée with 216 Old German and Old Dutch masters; in 1828, the king managed to also purchase the collection of the Prince Wallerstein, with 219 Upper German and Upper Swabian paintings. In 1838 Johann Georg von Dillis issued the first catalogue. After the times of King Ludwig I the acquisitions almost ended. Only from 1875 the directors Franz von Reber and Hugo von Tschudi secured important new acquisitions, such as the Madonna of the Carnation of Leonardo da Vinci and The Disrobing of Christ of El Greco. The predilection of the Wittelsbach rulers for some painters made the collection quite strong in those areas but neglected others. Since the 1960s the Pinakothek has filled some of these gaps: for example, a deficit of 18th-century paintings was addressed by the integration into the collection of works loaned from two Bavarian banks. Among these paintings were Nicolas Lancret's The Bird Cage and François Boucher's Madame Pompadour. In April 1988, the serial vandal Hans-Joachim Bohlmann splashed acid on three paintings by Albrecht Dürer, namely Lamentation for Christ, Paumgartner Altar and Mater Dolarosa inflicting damage estimated at 35 million euros. In 1990 Dierick Bouts' Ecce agnus dei was acquired. On 5 August 2014, the museum rejected a request by a descendant of the banker Carl Hagen for the repatriation of Jacob Ochtervelt's Das Zitronenscheibchen (The Lemon Slice) on the grounds that it had been unlawfully acquired as a result of Nazi persecution. An investigation by the museum established that it had been lawfully purchased at the time for a fair price and that the Hagen family's interest extended only to a security on the painting. Collection The museum is under the supervision of the Bavarian State Painting Collections which also owns an expanded collection of several thousand European paintings from the 13th to 18th centuries. Especially its collection of Early Italian, Old German, Old Dutch and Flemish paintings is one of the most important in the world. More than 800 of these paintings are exhibited at the Old Pinakothek. Due to limited space in the building, some associated galleries throughout Bavaria such as the baroque galleries in Schleissheim Palace and Neuburg Palace additionally have works by the Old Masters on display.
