The Kupferstichkabinett was officially founded in 1831, with a collection of drawings and watercolours acquired by Frederick William I in 1652 at its core [REF].
In 1986 the Kupferstichkabinett took over the graphics collection of the National Gallery of Berlin, whose emphasis was on 20th-century prints, including Expressionist works that the Nazis had classified as "degenerate" and confiscated.
