One of the saplings grown from Anne Frank's beloved chestnut tree has been cut down and stolen, reports the Jerusalem Post. Someone felled the 8-foot tree that had been planted outside the Anne Frank School in Frankurt, Germany, at some point over the last week. It was one of several grown from cuttings of the chestnut tree that stood outside Frank's home in Amsterdam and lifted her spirits while she was in hiding from the Nazis. “It was, obviously, more than just a tree for us,” says a school spokesperson. It's also impossible to replace: A storm brought down the original tree in 2010. (More Anne Frank stories.)
