The paintings occupied the upper floor with the collection of antiquities on the lower. At this point, the collection contained nearly 1200 paintings, with a core of 160 from the 17th-century collection of Marchese Vincenzo Giustiniani, bought in Paris in 1815. An even more important purchase was 677 paintings from the collection formed in Berlin by the English merchant Edward Solly, which were acquired in 1821; Solly was an early collector of Italian Trecento and Quattrocento paintings and Early Netherlandish painting. Purchases continued throughout the 19th century, with 345 works acquired during the inaugural directorship of Gustav Friedrich Waagen from 1830–1868, though paintings competed with antiquities for rather reduced purchasing budgets. After Berlin became the capital of the new German Empire in 1871 the funds available greatly increased, and purchases accelerated, as Berlin strove to catch up with the greatest European collections. In 1874 the collection acquired the best of the collection of mostly north European art formed by the industrialist Barthold Suermondt of Aachen after his business collapsed. This was handled for the museum by the art historian Wilhelm von Bode, who had joined in 1872, and was to be the Berlin Museums' greatest Director. He headed the sculpture collections from 1883, then the paintings from 1890, becoming general head of the Berlin Museums from 1890 to 1920. A specialist in Rembrandt and Dutch painting, he made very significant additions in those areas but did not neglect Italian painting. His leadership marked the rise of the Gemäldegalerie to international prominence. In 1904 the Gemäldegalerie moved to the newly built Kaiser Friedrich Museum, now the Bode Museum, where the collection continued to expand. The museum was badly damaged during World War II, but most of the collection survived the war in shelters across Germany. At the end of the war, however, 400 works that were regarded as too large to take to the remoter hiding places were destroyed in a fire in a Flak tower that served as a bomb shelter. Many important altarpieces and other large works were lost, and the collection remains short of very large works compared to the other major European collections. Furthermore, several hundred paintings were looted by Russian or American soldiers or confiscated by the Red Army and never returned, although in June 2006 a small painting by Alessandro Allori, missing since 1944, was returned by the British journalist Charles Wheeler, who had picked
