Before and during World War II the museum was put on a shoestring budget by the Nazi party and many exhibits were allowed to get out of date with a few exceptions such as the new automobile room dedicated 7 May 1937. By the end of 1944 the museum was badly damaged by air bombings with 80% of the buildings and 20% of the exhibits damaged or destroyed. As Allied troops marched into Munich in April 1945, museum director, Karl Bässler, barely managed to keep the last standing bridge to Museum Island from being blown up by retreating German troops.
