The Jewish Museum Berlin (Jüdisches Museum Berlin), in Berlin, Germany, covers two millennia of German Jewish history. It consists of two buildings. One is the old Kollegienhaus, a former courthouse, built in the 18th century. The other, a new addition specifically built for the museum, designed by world-renowned architect Daniel Libeskind. This was one of the first buildings in Berlin designed after German reunification. The museum opened to the public in 2001. Princeton professor W. Michael Blumenthal, who was born near Berlin and was later President Jimmy Carter’s Secretary of the Treasury, has been the director of the museum since December 1997.
