Berlin’s Nationalgalerie announced on Thursday that it has added two significant examples of German expressionism to its collection, Art Magazin reported.

The Freunde der Nationalgalerie (Friends of the National Gallery, an association of benefactors) acquired an Ernst Ludwig Kirchner portrait of fellow artist Max Liebermann as well as a self portrait by Max Liebermann.

Kirchner’s oil painting Max Liebermann in seinem Atelier, (1926-1928) (Max Liebermann in His Studio) is one of the artist’s late works and was bequeathed to the Nationalgalerie by Manuela Müller, a longtime member of the Freundeskreis or friends group.

Liebermann’s Selbstbildnis, stehend in Dreiviertelfigur, beide Hände in den Hosentaschen (1915) (Self Portrait, Standing in Three-Quarter Figure, Both Hands in Pockets) was donated by an anonymous member of the Freundeskreis.

Chairperson of the Freunde der Nationalgalerie, Gabriele Quandt, told Art Magazin on Wednesday “This is not only a fantastic double-acquisition, it also shows how deeply rooted the idea of patronage is within our association.”

Unfortunately for art enthusiasts eager to see the new works, the paintings will not be placed on view until the imminent renovation of the Neue Nationalgalerie is completed (see “String of Berlin Museum Closures Begin“). Those renovations are estimated to conclude in 2018. Until then, the works will be kept in storage.

The Freunde der Nationalgalerie has approximately 1400 members and has supported the Nationalgalerie institutions for the past 37 years. They help finance both exhibitions and acquisitions.
