The Collection Bayer

When you are in Berlin at the Potsdamer Platz, not everybody knows that you have to walk only a few steps to find the impressing museum, the Martin-Gropius-Bau. The building was erected in 1877 as an Arts and Crafts Museum. Since 1981, when the ruin had been restaurated, you can not only see exhibitions of photography and art, but also admire the building with its high atrium.  

Yesterday (they are open on Monday) I went to see the Collection Bayer (from the chemical and pharmaceutical international concern).  The paintings, normally hanging in the offices of their (important, I guess) employees are now "out of office", because the concern is celebrating its 150 years company anniversary. In 1909 Carl Duisberg asked Max Liebermann to paint a portrait of him, which was the foundation. At first the concern bought paintings to educate their employees - now they own over 2000 works of art.  
It is the first time that 240 of their works of art are presented to the public. And the names of the artists are exquisite: Ernst Ludwig Kirchner, Karl Schmidt-Rottluff, Max Pechstein, Emil Nolde,Max Beckmann, Lyonel Feininger, Georges Braques, Pablo Picasso, Joan Mirós, Gerhard Richter, Sam Francis, Andy Warhol - to name a few. 
The exhibition is divided into four parts: German Expressionism, École Paris, After-War-and Informal Art, and American modern art.  I liked a drawing of David Hockney, "Rapunzel" very much, and of course Emil Nolde's paintings. As  nobody is allowed to photograph, you have to put up with the poster, sorry.
